2019 Mercedes-Benz GLE (W167) -

Press Release:

– Affalterbach

With the new high-performance GLE 63 S SUV, Mercedes-AMG continues a 20 year tradition: in 1999 the M-Class based ML 55 AMG set a new standard in SUV performance with its handcrafted 342 hp V8 engine. This high-performance benchmark has been raised yet again with its current successor, the new Mercedes-AMG GLE 63 S. This top-of-the-line performer comes to the starting line with state-of-the-art engine technology: the AMG 4.0-liter V8 biturbo engine generates 603 hp in the GLE 63 S and is paired for the first time with an EQ Boost starter-generator. This sophisticated system provides an additional electric output of up to 21 hp, powers the 48-volt on-board electrical system and helps optimize efficiency. Fully variable all-wheel drive, air suspension with adaptive damping and active roll stabilization along with an extremely fast-shifting TCT 9G transmission, further enhance this top-performer's dynamics. On top of these performance enhancements, all the advantages of a luxury SUV also shine through: ample visibility and road presence, plenty of space for passengers and luggage, high- quality materials and the brand's very latest driving assistance, infotainment and connectivity features. Even more versatility is provided thanks to improved off-road capabilities with the two additional drive programs of "Trail" and "Sand", as well as a variable vehicle level. The new GLE 63 S is where high on- road performance, first-class off-road characteristics and remarkable day-to-day usability meet.

"With our new GLE Performance models we are transforming a 20-year tradition into the future. For the first time we are electrifying our well-proven 4.0-liter V8 biturbo engine with an EQ Boost starter-alternator and a 48-volt on-board electrical system. As such we are embarking on another new chapter of our drive technology, which we are also successively extending further to other model series as we move towards electrification and hybridization. With our new premium SUVs, our customers can look forward to an unrivalled package of Driving Performance, high day-to-day suitability, optimum traction on practically all surfaces and also comfort on long journeys with high levels of efficiency," says Tobias Moers, Chairman of the Board of Management of Mercedes-AMG GmbH.

Featuring an EQ Boost starter-generator for the first time: the AMG 4.0-liter V8 biturbo engine

The 4.0-liter V8 biturbo engine in the new GLE 63 S is paired for the first time with an integrated EQ Boost starter-generator. It combines a starter motor and an alternator in a single, powerful electric motor integrated between the engine and the transmission. An additional 21 hp of output plus 184 lb-ft of torque can be called upon temporarily, enabling even more responsive acceleration. This innovative component supplies power to the 48-volt on-board electrical system and is used as a generator to perform hybrid functions. These include boost, recuperation, gliding and the virtually imperceptible restarting of the engine with the start/stop function. For the first time, the EQ Boost starter-generator is also responsible for idle speed control. This allows fuel savings that were previously reserved for high-voltage hybrid technology.

The AMG 4.0-liter V8 engine works with well-proven twin turbocharging, in which two exhaust-gas turbochargers are arranged between the cylinder banks. The advantages of the "hot inside V" are the compact engine design and the immediate response of the exhaust-gas turbochargers. These are implemented using twin-scroll technology to make optimal use of the exhaust gas flow and improve responses even further.

Spray-guided direct fuel injection with piezo injectors, the all-aluminum crankcase, the four-valve-per- cylinder design with camshaft adjustment, air-water charge air cooling, alternator management, the ECO start/stop function and the gliding mode have all been retained.

Improved efficiency: intelligent AMG Cylinder Management

For increased efficiency, Mercedes-AMG has also equipped the V8 engine with cylinder shut-off. In the partial-load range, cylinders two, three, five and eight are deactivated, which reduces the fuel consumption. When the driver has selected the "Comfort" drive program, the cylinder deactivation system is available in a wide range from 1,000 to 3,250 rpm. A special display in the instrument cluster indicates whether the cylinder deactivation system is in use and whether the engine is presently operating with four or eight-cylinders. The shift between these two operating states is immediate, fast and torque-neutral, so the transition is not noticeable.

The new GLE 63 S also features innovative active engine mounts. These active mounts can achieve as soft a connection as possible to the powertrain for high comfort, and as rigid a connection as possible for optimized driving dynamics. The active mounts can realize these competing aims by seamlessly and quickly adapting their rigidity to the respective driving conditions.

Optimized handling: air suspension with continuously adjustable damping

The standard AMG RIDE CONTROL+ air suspension and the adaptively adjustable ADS+ (Adaptive Damping System) combine great agility with maximum traction and high everyday comfort. The damping characteristics can be preselected in three stages - "Comfort", "Sport" and "Sport+", allowing a clear distinction between high long-distance comfort and sporty driving dynamics.

Thanks to pneumatic self-levelling, the new GLE 63 S maintains a constant ride height regardless of the vehicle load. This can be adjusted depending on the driving mode, or manually using a rocker switch in the center console. The vehicle level is generally lowered by 0.4 inches when selecting the AMG DYNAMIC SELECT drive programs "Sport", "Sport+" and "RACE". In the "Comfort" driving mode, the vehicle is lowered by 0.4 inches from a speed of 75 mph, and raised back to normal level when the speed falls below 44 mph. This reduces aerodynamic drag and therefore fuel consumption. In addition, handling stability is improved thanks to a lower center of gravity.

In the drive programs "Trail" and "Sand", the suspension is raised by 2.16 inches to increase ground clearance on poor surfaces, and automatically lowered to normal level when the speed reaches 44 mph. This function can also be controlled using the rocker switch.

Agile and precise: AMG ACTIVE RIDE CONTROL roll stabilization

The AMG-specific dynamics configuration is greatly enhanced by the active roll stabilization system ACTIVE RIDE CONTROL with 48-volt power. This system precisely compensates for changes in vehicle movement. This ensures that even in sporty situations near the limits, the handling remains precisely controllable and extremely direct. The system uses two independently operating, electromechanical actuators at the front and rear axles, each with an integrated planetary gear. The stabilization system not only reduces body roll when cornering, but also allows for more precise tuning of the cornering and load cycle properties. In addition, it increases ride comfort when driving in a straight line, through balancing out one-sided road bumps, for example. Body movements can be actively adapted to the driving status, which intensifies the driving experience.

Another benefit compared with the usual hydraulic-based systems is a significantly faster response. The AMG control system can adapt the driving status to the conditions in a matter of milliseconds.

AMG Performance 4MATIC+ all-wheel drive with fully variable torque distribution

The performance-oriented all-wheel drive system continuously ensures the best possible ratio of performance dynamics, high traction and efficiency. An electromechanically controlled clutch connects the permanently driven rear axle variably to the front axle. The best possible torque split is continuously computed according to the driving conditions and driver's input. The transition from rear-wheel to all- wheel drive and vice versa is seamless, as the intelligent control is integrated into the overall vehicle system architecture. Alongside traction and lateral dynamics, the all-wheel drive also improves the longitudinal dynamics for even more powerful acceleration. Torque distribution is influenced by the driving speed, the lateral and longitudinal acceleration and the steering angle, and also the difference in rotational speed between the individual wheels and the gear selected.

The all-wheel drive is controlled depending on the selected stage of the 3-stage Electronic Stability Program ESP® – from sporty with a focus on safety to highly dynamic. The 4ETS dynamic handling control system further enhances handling safety and agility, in particular on slippery surfaces or on surfaces with different friction coefficients. It uses brake interventions to keep individual driven wheels from spinning when starting off or accelerating. At the same time the differential locking effect enables the drive torque to be shifted to the wheels that are not spinning.

More traction and improved dynamics: the locking differential

To further improve traction and driving situations, the GLE 63 S has a standard electronically controlled locking differential at the rear axle. Slip is suppressed at the inner wheel on turns, ensuring optimum grip and maximum handling safety. The driver is therefore able to accelerate out of corners earlier and with more power thanks to the improved traction. The vehicle remains more stable when braking from high speed, while the limited-slip differential also improves traction when accelerating from a standstill.

Direct and immediate: AMG speed-sensitive sports steering

The electromechanical speed-sensitive power steering has a variable ratio. It impresses with its precise feedback thanks to the AMG-specific rack-and-pinion steering with a variable ratio. The steering assistance is assigned to the various stages of the AMG DYNAMICS system. The configuration in "Basic" and "Advanced" is comfort-oriented. In "Pro" and "Master", a configuration is programmed that supports a sporty driving style and provides more road feedback.

Good control and fade-resistant: the AMG high-performance braking systems

In line with the high engine output and its associated performance, the new GLE 63 S includes a large and highly-effective high-performance brake system. Featuring 6-piston fixed brake calipers and 16 x 1.5 inch brake discs at the front, plus single-piston floating brake calipers and 14.6 x 1.3 inch discs at the rear. The GLE 63 S also features red brake calipers.

As an option, a high-performance ceramic braking system with bronze-colored 6-piston fixed calipers at the front and single-piston floating brake calipers at the rear can be ordered, saving weight while also reducing unsprung mass. Further advantages include strong fading stability under high stress and a long operating life with particularly fast responses.

Fast and agile: the AMG SPEEDSHIFT TCT 9G transmission

The AMG SPEEDSHIFT TCT 9G transmission is specially tuned to the requirements of the eight-cylinder engine in the GLE 63 S. Systematic hardware and software developments have made it possible to further optimize the reaction times. This improvement means that automatic and manual shift commands can be implemented more quickly than ever before. The extensively tailored software enables extremely short shift times and fast multiple downshifts, delivering an especially dynamic gearshifting experience thanks to the double-declutching function. Gear changes are performed with no interruption in tractive power. Dynamic acceleration and very short shift times are available, as well as a more fuel-efficient driving style - depending on the selected mode.

Highlights of the transmission:

• shift characteristics adapted to the selected AMG DYNAMIC SELECT drive program
• in manual "M" mode the transmission responds directly to manual shift commands by the driver – the powertrain responds precisely and executes the commands almost instantly
• automatic double-declutching when downshifting: this effect is automatically active in drive programs "Sport", "Sport+" and "RACE"
• the ECO start/stop function is automatically active in the "Comfort" drive program
• the "gliding" function can be individually activated in "Individual" mode

Driving pleasure to the power of seven: AMG DYNAMIC SELECT and AMG DYNAMICS

The seven DYNAMIC SELECT drive programs of Comfort, Sport, Sport+, Individual, RACE, Trail and Sand enable a variety of driving experiences with a wide spread between maximum comfort and agile sportiness. The modes modify key parameters, such as the response of the engine, transmission, suspension and steering.

• "Comfort": comfortable and fuel-efficient driving, e.g. thanks to early upshifts. Suspension and steering are set up with an emphasis on comfort.
• "Sport": Sporty characteristics thanks to more agile responses to accelerator pedal inputs, shorter shift times, earlier and more precise downshifts thanks to double-declutching. This mode also includes a more dynamic suspension setup.
• "Sport+": extremely sporty characteristics thanks to an even quicker throttle response, double- declutching on downshifts and targeted torque interventions on upshifts with cylinder deactivation for optimized shift times. Increased idle speed for faster pulling away. An even more dynamic setup for suspension, steering and powertrain.
• "Individual": individual adjustment of the drive system, transmission, AMG DYNAMICS, suspension and exhaust system. In addition, the gliding function is available in the "Reduced" and "Moderate" drive settings.
• "RACE": This drive program is designed for highly dynamic driving on closed race circuits. In this program, all of the parameters are configured for maximum performance.
• "Trail": safe driving at maximum performance on soft, muddy or slippery ground. The suspension is raised to a higher level (2.16 inches more ground clearance). From 44 mph the suspension is automatically lowered again.
• "Sand": these adjustments to the suspension and the 4MATIC+ all-wheel drive are made for sporty driving on loose, sandy surfaces. The suspension is raised to a higher level (2.16 inches more ground clearance). From 44 mph the suspension is automatically lowered again.

The drive modes are linked to the AMG DYNAMICS agility control, which means that the handling characteristics can be closely matched with a variety of requirements and driving conditions. Behind the umbrella term AMG DYNAMICS are the agility functions "Basic", "Advanced", "Pro" and "Master", whose functions are automatically selected by the respective drive program. Additionally there are the "Traction" and "Slide" levels in the off-road "Trail" and "Sand" drive programs when the ESP® is deactivated.

Parameters relevant to driving, such as the response of the engine and suspension or the control thresholds of the completely redeveloped ESP®, are intelligently adapted according to the drive program. The spectrum ranges from very stable and smooth to highly dynamic. The "Master" mode stored in the RACE drive program ensures optimum agility and brings out the high driving dynamics potential to maximum effect -- through higher yaw rates and a faster response from the accelerator pedal, gearshift system, rear axle steering, electronically controlled rear axle locking differential or brake force distribution of the all-wheel drive system.

Irrespective of the drive program, the driver can use the buttons in the center console or control on the steering wheel to directly select manual transmission mode, the favored suspension level and also the exhaust system setting, for example.

Exterior design – muscular and distinctive

The exterior design theme embodies sheer energy and Performance Luxury. The AMG-specific radiator grille with vertical louvers reaffirms a clear membership in the AMG model family, while the dynamic arrow-shape of the front section with its small approach angle emphasizes the distinctive proportions.

As a typical feature of AMG performance models, the front bumper features a dynamic A-wing design painted in the vehicle color and includes black air intakes. Imposing powerdomes in the hood and a front splitter in silver chrome also emphasize the sharper all-round design.

The side skirts, exterior mirror housings and flared wheel arches are painted in the vehicle color, and seamlessly blend into the muscular overall look. Different wheel/tire combinations cover a variety of driving requirements. The GLE 63 S comes with 21-inch wheels as standard. Other wheel variants with diameters from 21 to 22 inches are optionally available.

The newly designed rear bumper with AMG-specific details such as a striking diffuser and a trim strip in silver shadow visually accentuate the vehicle's width. The special AMG exhaust system with two rectangular twin tailpipe trims and the distinctive roof spoiler round off the sporty look.

Further sporty design options are available with the AMG Night package. This includes the front splitter, front and rear bumper trim, inserts in the side skirts, mirror caps and window frames in distinctive black. The twin tailpipe trim elements are also finished in black chrome.

Interior design – progressive elegance and robust ambience

The high-quality interior is characterized by a sporty ambience with a dynamic and exclusive touch. The standard AMG seats are upholstered in Exclusive Nappa Leather, provide optimized lateral support and have an AMG-specific seat pattern layout with an "AMG" badge in the front backrests. Exclusive nappa leather with a crystal grey seat band and crystal grey contrast topstitching, along with seat belts in dignified crystal grey is optionally available. Other available interior choices include: leather variants in black, black/truffle brown and black/red pepper. Individually adjustable 64-color ambient lighting is equipped as standard.

AMG-specific interior appointments and controls provide a hallmark AMG atmosphere and support sporty, precise handling. The latest generation, three-spoke AMG Performance steering wheel with aluminum shift paddles impresses with its optimized driver-oriented ergonomics. The steering wheel rim is lined in nappa leather/DINAMICA and features a black 12-o'clock marking. Further options include AMG Drive Unit steering wheel buttons for quick operation of settings related to the driving-dynamics.

The center console has an AMG-specific control panel with additional switches, which can adjust the 3-stage ESP®, manual transmission mode, the adaptive damping adjustment, the standard AMG Performance exhaust system and the suspension level.

Alongside the AMG brushed stainless steel sport pedals, door sill panels and black floor mats with "AMG" lettering further accentuate the sporty look. A wide range of high-quality interior trim elements is available for further individualization of the interior. AMG trim elements in carbon fiber lend a particularly sporty and exclusive touch to the interior.

Featuring AMG-specific displays: the MBUX infotainment system

The innovative MBUX control and display concept in the new GLE 63 S creates an even closer bond between vehicle, driver and passengers. At the same time, the latest version of the infotainment system contributes to great day-to-day practicality. Vibrant displays such as the particularly striking Supersport mode with a central rev counter and 3D-look scales lend visual depth to the instrument display.

Whether it's operated with the touchpad, Touch Control buttons on the steering wheel, by voice control or gesture control: the control concept is both versatile and flexible. Thanks to the innovative voice control – activated with the keyword "Hey Mercedes" – the AI software recognizes and understands practically all commands common in infotainment and vehicle control – even when spoken indirectly.

With the four AMG-specific display styles "Modern Classic", "Sporty", "Discreet" or "Supersport", the vehicle functions are directly visualized on the instrument cluster on the left side and on the touchscreen display on the right. Visually, the two displays connect under one shared glass cover and blend into a Widescreen Cockpit.

In the "Supersport" mode, there is extensive additional information specific to AMG, such as a prompt borrowed from the world of motorsport to shift up in manual transmission mode. Via the AMG menu, the driver can call up various special displays:

• Gear display - with yellow "M" symbol in manual mode
• Warm-Up menu - engine and transmission oil temperature
• Set-Up menu - AMG DYNAMIC SELECT settings
• G-Meter – longitudinal and lateral acceleration forces
• Race-Timer – stopwatch, lap and sector times
• Engine data – output and torque, engine oil and transmission oil temperature

The newly designed visualizations in the multimedia display enable select vehicle functions to be experienced in new ways, including an animated presentation of the driving assistance, vehicle and communication systems, as well as the drive programs. When the AMG-specific DYNAMIC SELECT drive programs "Trail" and "Sand" are activated, off-road-specific settings such as gradient, incline and differential lock can be selected and displayed in the media display.

Increased comfort is assured by the optional ENERGIZING package Plus. It bundles many premium equipment items and includes: multi-contour seats for the driver and front passenger, seat climate control for the driver and front passenger (with seat heating and seat ventilation), the Warmth and Comfort package, the AIR-BALANCE package (fragrances, ionization and air purification) and six ENERGIZING Comfort programs as well as the ENERGIZING COACH for intelligent pre-selection of ENERGIZING Comfort programs to suit the driving situation and the driver's condition. Also on board: ambient lighting with program-specific lighting moods.

Comfort and support while driving: Driving Assistance

The optional Driving Assistance package supports the driver on a situational basis, with speed adaptation, steering, lane changes and even when there is a risk of collision.

Components include Active Distance Assist DISTRONIC, Active Speed Limit Assist, extended automatic restart on motorways, speed adjustment based on the route, Active Steering Assist, Active Lane Change Assist, Active Emergency Stop Assist, Emergency Lane Function; Active Brake Assist, Cornering and Cross-Traffic Function, End of Traffic Emergency Brake Function, Evasive Steering Assist; Active Lane Keeping Assist, Active Blind Spot Assist, Exit Warning Function; PRE-SAFE® PLUS, Traffic Sign Assist, Active Stop-and-Go Assist, and PRE-SAFE® Impulse Side.

The GLE63s is packing some serious arsenal under its belt in just about all of its capabilities.
That is some impressive info!
No wonder its main competitor is pushing the competition package.

 

[Grosser]

No wonder its main competitor is pushing the competition package.

They didn't name Competiton trim so they could tell their customers: "This CP will beat any RS/AMG", they just needed a name for upper M models it's same for RS Plus/Perfomance and AMG S. Today they almost forcing you to choose upper trims of each division.

 

[domleo999]

Correct me if i'm wrong, but are the GLE53 & 63 sharing the same bumper?

What visual differences do they have?

 

[GTA45E]

^
Yep, bumper and grill.
Only difference it appears is the metal strip on the 63. The 53s are considered AMG models so this was expected in my book. (The F/L E53 will probably get the same bumper and grill as the E63 model as well.)

so lazy!

I don't think it has anything to do with lazy.
Mercedes GLE is not meant to be the hardcore looking SUV this has always been more of a all-rounder suv from Mercedes and the least aggressive styling wise from a Mercedes..I think it looks very good and does a great job for what Mercedes wants from the SUV.. If you looking for more hardcore MB SUV then G class or GLC or even the GLS in some way.

I mean lazy in the way the 53 and 63 don't hardly differentiate.

the X5M50i and X5M look extremely different, same with the SQ8 and RSQ8.

I understand the understated look they are going for but i've been seeing the same AMG bumper rolled out on every AMG model for some time, some differentiation would be nice.

The optional 48 Volt E-ABC controller works together with AIRMATIC.

Operating principle: How E-ACTIVE Body Control works

E-ACTIVE BODY CONTROL in the GLE supplements the air suspension with semi-supporting hydropneumatics. The air springs bear the base load of the vehicle body and gradually regulate the level. The hydropneumatics generate dynamic forces that overlay the air suspension forces, and actively support and dampen the vehicle body.

At each wheel, a damper is installed within the axle whose two working chambers have an adjustable damping valve and a hydraulic pressure reservoir. The damper is connected to an intelligent motor/pump unit in the 48 V network by hydraulic lines. Actuation of the motor/pump unit enables the hydraulic fluid to be displaced to create a difference in pressure within the damper, allowing an active force to be generated.

The motor/pump units at all four wheels are coordinated by a central control unit which also actuates the valves and the compressor for the air spring, and therefore always controls the entire suspension system. It was developed according to the safety standard ISO 26262.

The transition from a belt-driven hydraulic pump to an electric 48-volt pump also takes into account the increasing electrification of the powertrain: the combustion engine is idle increasingly often – or not used at all.

E-ACTIVE BODY CONTROL CHASSIS WITH ROAD SURFACE SCAN

The E-ACTIVE BODY CONTROL suspension, combined with ROAD SURFACE SCAN and CURVE cornering capability, provides a hitherto impossible combination of driving dynamics and comfort, underscoring Mercedes-Benz's claim to build the world's most intelligent SUV suspension.

Components of the E-ACTIVE BODY CONTROL suspension (Code 490):

- Fully active, electro-hydraulic suspension on 48 volt basic
- Four DYNAMIC SELECT driving programs, some with an intensifying plus option:

A look behind the scenes at Mercedes-Benz Handling Development: A question of character: this is how the special driving character of a Mercedes-Benz is created

Sindelfingen. A vehicle is driving on a country road on a cold, dull December morning. The road surface leaves a lot to be desired, and potholes and ruts make for uneven road conditions. The driver does not notice any of this. He effortlessly steers the vehicle along the route and through sharp bends. Even an obstacle which suddenly appears is effortlessly avoided by the vehicle, without setting the driver's pulse racing too much. This special feeling of safety, comfort and effortless superiority is unmistakeable. It is inherent to a Mercedes. The developers behind it refer to this feeling as the "Mercedes-Benz driving character".

Development is a matter of character

"We aspire to make our vehicles immediately recognisable. Not just through the hallmark Mercedes design, but also the handling," is how Markus Riedel, Head of the "Ride & Handling" Centre, sums up his team's main mission. "In concrete terms a Mercedes is characterised by three very pronounced traits: optimum ride comfort, high driving safety and tangible self-assurance. In every situation a Mercedes driver must have the impression that their vehicle still has reserves." It is the job of the engineers at the Sindelfingen Mercedes-Benz Technology Centre to constantly optimise these three goals and develop them further for every new model platform.

At the start of every development cycle the required specification of these three top properties, supplemented by sportiness and precision, is translated into over 90 measurable physical characteristic values, including for vertical, lateral and longitudinal dynamics. Countless calculations, design variants and simulations on supercomputers are necessary before the parameters on paper can be fed into the target description, i.e. into the specification of the component parts and wheel alignment systems. "The real art of the development process is for us to reconcile these statistical values with one another to such an extent that they create a complete driving experience geared to humans," says Markus Riedel, explaining the challenges in developing the handling characteristics. Because for all this digitisation and technology: it is the subjective perception whilst driving that is decisive.

This means that all the objective statistical values – whether calculated or measured – have to be interpreted with subjective perception. This is the only way in which the Mercedes-Benz driving character can be created.

"Modern handling is therefore developed through the triad of digital simulation on the computer, measurements on test stands and finishing touches through subjective fine-tuning with real vehicles. Each of these three instruments has its strengths, but also its limitations. The actual art is now to combine them with one another optimally."

Feeling meets physics

To enable the checking of calculations to run efficiently, even at the early development phases in which there is as yet no actual prototype, there is the Driving Simulation Centre in Sindelfingen. In what is known as the Ride Simulator – two seats mounted next to one another on a hexapod with electrical regulators – the Mercedes-Benz chassis experts work, for example on the damping variance. With the aid of digital vehicle prototypes and the surface data of real test routes, the driver and co-driver can carry out virtual test drives and check how they find, for example, the same uneven road surface with a comfortably soft or sportily tauter suspension tuning. "With this digital transformation we save ourselves one to two coordination loops in testing with real prototypes. We have an entire collection full of virtual vehicles and driving situations in the computer which we can incorporate at the press of a button," Markus Riedel says, explaining how the process works.

This is where it is literally possible to experience at first hand a phenomenon familiar from the realm of acoustics: the masking effect. "When you are out on the road in a normal vehicle these days, you hardly notice the exterior noises such as wind noise, because they are overlaid by the engine noise. These noises are missing from an electric vehicle – and even the airstream seems much louder," Markus Riedel explains. It is a similar story with the various vibration frequencies: "Naturally we can try to dampen away all the vehicle's lower-frequency body movements. But the high-frequency vibrations remain – and this is that tingling in the stomach that many people find so unpleasant."

In the Handling or Moving-Base Driving Simulator one floor up, the focus is on the topic of safety and self-assurance. With its ball structure on a twelve-metre rail, the 360-degree screen, sound systems for reproducing the wind noise and a fast electric drive, it is not dissimilar to a flight simulator. Here, too, the data sets created by supercomputers serve to replicate driving situations which appear as real as possible to the test subjects. The difference is that they are sitting in a complete vehicle body here and can accelerate, steer and brake for themselves.

In this way even dynamic driving manoeuvres such as a double lane change or the effect that a strong lateral gust of wind has on the suspension can be studied extensively. "Many people think that in Development we just deal with steering, braking, damping, etc. But the Handling Simulator also helps us learn which tyres are suitable for which setup, or if the aerodynamics still need to be optimised," says Markus Riedel. The big advantage of simulations is that the results are always objective and reproducible, whilst subjective assessments in the actual test vehicle can tend to vary. Plus the control units required for handling have to be configured for the Mercedes-Benz driving character in a targeted manner. We have the Hardware-in-the-Loop laboratory for configuring the control units.

Loop by loop to the right setting

The rapid increase in electronic control units, whose tasks include assuming responsibility for the drive electronics and suspension in modern vehicles, calls for a level of testing which is as thorough as that on the suspension itself. One possible way of accelerating the development of vehicle components is a process called Hardware-in-the-Loop (HiL), which has been vehemently used and developed further at Mercedes-Benz ever since the infamous moose accident test. In the HiL laboratory, real control units, such as the ESP®, are connected to a supercomputer which simulates the vehicle's behaviour with the aid of computer models.

An example: the vehicle computer model drives through a slalom course at high speed and sends sensor data describing the vehicle behaviour to the ESP®. It reacts and in turn sends the corresponding control impulses back to the hydraulic brake, thus producing precisely the brake force required at the tyres to enable the vehicle to continue meeting the driver's wishes. This creates a loop.

In this way countless driving manoeuvres and all the suspension control units can be tested in a secure environment over and over again for a diverse range of vehicle platforms. There are now 22 functions integrated in the ESP® control unit. They have to be successfully tested in around 900 manoeuvres. And even if every single manoeuvre has to be performed in real time, a great deal of development time can be saved by including Hardware-in-the-Loop. "We can carry out nearly 20 million computing operations in one night on a HiL test stand. With this example alone you can see just what is possible thanks to digitisation. And we can also simulate marginal manoeuvres here too, without endangering any people or vehicles," comments Markus Riedel, explaining the value of Hardware-in-the-Loop for the development of handling.

On the test track

The test drives in the actual vehicle on real routes should of course only ever approach these limits with extreme care, if at all. In order to put the finishing touches to all the characteristic properties of the Mercedes-Benz driving character – so the ride comfort, driving safety, self-assurance, sportiness and precision – the vehicle itself is also tested and optimised. "It's just like a good wine. You can describe it in chemical terms, but that subtle something comes from people for people. As far as we are concerned the simulations cannot replace tests in real conditions. But they do help to put the actual prototypes onto the real test track faster and with a higher maturity level," is how Markus Riedel justifies the subsequent development phase on the test track.

"Testing on public roads, except for ride comfort, would be irresponsible," Markus Riedel explains. "And even when it comes to optimising the springing comfort the volume of traffic or the width of the road prevents us from always driving at the same speed on the same route in order to gain comparable impressions. In addition to this, good routes for fine-tuning are disappearing because they are being asphalted smooth. We measured these routes before they were overhauled and preserved them on the computer with all their dips and bumps, grooves and potholes. And on our test tracks we have faithfully reconstructed these roads. A modern S-Class can and must be measured against its predecessors on the same stretch, for example, from simulation to testing in the actual vehicle."

Even cobblestones were put down on a short section of the test track in Sindelfingen. On test tracks and for ride comfort on public roads, too, the pre-defined suspension settings are optimised and fine-tuned with various parameters in real conditions. Concrete motorways, for instance, present a special challenge. Here there are transverse joints at regular intervals, and when the vehicle speed is increased they cause higher-frequency agitation. The vehicles are tuned in such a way that the agitation is reduced as much as possible for the occupants.

The engineers do not like to compromise when it comes to handling: "We are dealing with technological development at the absolute limit here, and we want to optimise all the driving properties as much as possible," says Markus Riedel. "But if ever there are any conflicts of interest, then driving safety, ride comfort and self-assurance always have priority before sportiness or precision when we make our decisions." Depending on the vehicle platform, after years of development and countless test drives, in the end precisely the right suspension tuning is achieved that lends every single model its very special Mercedes-Benz driving character – so that drivers arrive at their destination relaxed, even after a long journey in difficult conditions.

MERCEDES-AMG GLE AND GLS 63: SALES RELEASE IN FEBRUARY

According to the current status, the new Mercedes-AMG GLE 63 (S) 4MATIC+ and the GLS 63 4MATIC+ model may become available to order in February 2020. So a little patience is required until you can order the top engines of the series.

GLE 63 (S) 4MATIC+ AND GLS 63 4MATIC+ - ORDER RELEASE IN FEBRUARY

To order the GLE 63 (S) 4MATIC+ or the GLS 63 4MATIC+ model with V8 bi-turbo engine and 612 PS / 450 kW with additional 16 kW / 22 PS from the EQ Boost starter generator, prospective customers have to wait a few more weeks. According to the current status, the sales release for the variants starts on February 19, 2020. We then expect deliveries within the first half of 2020.

STRONGEST MOTORIZATION IN THE GLE AND GLS

The waiting time is definitely worth it, especially since a GLE or GLS model with more than the motorization variant now offered has never been available. The AMG models also offer the latest technology from Mercedes-Benz and AMG from Affalterbach. However, the drivetrain for the SUV models comprises: 612 hp from the 4-liter V8 BiTurbo with integrated EQ Boost starter generator, which combines starter and alternator in one electric motor and is installed between the engine and transmission.

AMG MODEL WITH HYBRID FUNCTIONS

The 16 kW / 22 hp output, which can also be called up briefly, as well as 250 Nm torque of the electric motor are intended to provide particularly spontaneous sprints from a standing start and accelerations. The electric drive also provides the usual hybrid functions such as boosting, recuperation and sailing - and a shift in the load point. The almost imperceptible restart of the engine with the start-stop function is also interesting.

I don't know why but I feel so excited about this car, I am sure that Mercedes Benz fans can't wait to purchase this SUV next month.

Look at how lush the rear end is without parking sensors on the colour coded panels. It would look awesome debadged.

Mercedes prices new GLE and GLC plug-in hybrid SUVs
Diesel-electric GLE arrives with 61-mile electric range and 256mpg; is joined by 128mpg petrol-electric GLC

by Greg Kable

Mercedes-Benz has revealed UK pricing for the new diesel-electric GLE, which has class-leading electric-only range and CO2 emissions, and the updated petrol-electric GLC.

The GLE 350de 4Matic is the latest in an extended range of new diesel-electric plug-in hybrids from Mercedes, following the C300de and E300de, and is on sale now, priced from £61,360.

Entry-level AMG Line models are equipped with 20in alloy wheels, adaptive headlight assistance, a DAB radio, heated front seats, a 12.3in digital display and wireless smartphone charging.

Prices rise to £64,860 for AMG Line Premium, which brings extras including electrically adjustable front seats and a 360deg parking camera, and £68,360 for range-topping AMG Line Premium Plus, which includes keyless entry, a panoramic sunroof and a Burmester sound system.

While the C300de and E300de use a relatively small 13.5kWh lithium ion battery, the GLE350de has a sizeable 31.2kWh pack - the largest Mercedes has yet used in a series-production hybrid model. The result is a WLTP electric-only range of 61.5 miles.

This move mirrors that of BMW, which has fitted a 24.0 kWh battery to the X5 xDrive45e petrol-electric plug-in hybrid to give it an official zero-emissions range of 54.1 miles.

At the heart of the GLE 350de's driveline is a longitudinally mounted turbocharged 2.0-litre four-cylinder diesel engine that develops 192bhp and 295lb ft of torque. This is supported by 134bhp and 324lb ft from an electric motor mounted within the standard nine-speed automatic gearbox.

Together, the two power sources provide a total system output of 315bhp and 516lb ft – 11bhp shy but equal in torque to the turbocharged 3.0-litre in-line six-cylinder diesel engine of the GLE 400d. For comparison, the turbocharged 3.0-litre in-line six-cylinder petrol engine and electric motor of the X5 xDrive45e deliver a combined 389bhp and 442lb ft.

The combined reserves are sufficient, says Mercedes, to propel the four-wheel-drive GLE 350de from 0-62mph in 6.8sec and up to a limited top speed of 131mph. In electric mode, top speed is limited to 100mph.

The 31.2kWh battery provides the GLE 350de an official electric-only range of between 55.9 and 61.5miles on the WLTP cycle. This correlates to combined fuel consumption of 256.8mpg and CO2 emissions of 29g/km.

The GLE 350de supports both AC and DC charging. With a maximum DC charge rate of 60kW, it can recharge in approximately half an hour.

The large battery has compromised the GLE's boot slightly, however: overall luggage capacity drops from 2055 litres to 1915 litres.

The GLE 350de is among 20 plug-in hybrid models that Mercedes plans to launch by the end of 2020.

New Mercedes GLC 300e is more efficient, thanks to bigger battery

In a further boost to the line-up, Mercedes has also revealed pricing for the updated GLC 300e 4Matic petrol-electric plug-in hybrid.

The BMW X3 xDrive30e rival is available now, priced from £49,687 and equipped as standard with 19in alloy wheels, AMG styling elements and sports seats. Mid-range AMG Premium trim costs £53,187 and brings 20in rims, multibeam LED headlights and leather seats, while top-rung Premium Plus trim includes a panoramic sunroof, a Burmester sound system and the Memory Package from £56,937.

The facelifted GLC variant receives a heavily upgraded driveline that yields a WLTP-certified electric-only range of 26.7 miles and a CO2 rating of 51g/km.

Key among its developments is a new 13.5kWh battery, as used by the C300e and E300e, which replaces a 8.7kWh battery.

Power for the GLC 300e is provided by a longitudinally mounted turbocharged 2.0-litre four-cylinder petrol engine that develops 208bhp and 258lb ft of torque. It's supported by 121bhp and 324lb ft from a gearbox-mounted electric motor. The result is the same 315bhp and 516lb ft combined output as the GLE 350de.

Mercedes claims 0-62mph acceleration in 5.7sec and a limited top speed of 143mph, or 81mph in electric mode.

The GLC 300e's new 13.5kWh battery provides a WLTP electric-only range of between 24.2 and 26.7 miles, giving a combined consumption figure of 128.4mpg and CO2 emissions of 51g/km.

Like the pre-facelift model, the GLC 300e supports only AC charging.

Its key rival, the X3 xDrive30e, runs a turbocharged 2.0-litre four-cylinder petrol engine and an electric motor for a combined output of 248bhp and 310lb ft. Its 12.0kWh battery provides a claimed electric-only range of up to 31 miles, giving it an official consumption figure of 117.7mph and average CO2 emissions of 56g/km.
