RML Group marks 40-year milestone with four innovative new products!

• UK’s leading high-performance automotive engineering company celebrates 40 years of engineering excellence and motorsport success
• Products include an all-new track day car; a super high-performance battery pack; a Le Mans Hypercar-inspired Porsche 911-based road car; and a heritage SuperClassic Aston Martin V8
• The four launches, one to mark each decade, are the first from RML Group’s four new dedicated divisions: Motorsport; Engineering; Power; and Bespoke

Wellingborough, Northampton, August 5, 2024: RML Group Ltd, the UK’s leading high-performance automotive engineering specialist, today marks its 40th year of engineering excellence with the unveiling of four new innovative products.

The first, from the Motorsport division, builds on all of the company’s multi-championship winning experience to create an all-new track day car. Codenamed P40, the ultra-lightweight, super-safe race car uses Formula 1-inspired aerodynamic technology to reach new levels of speed and handling for track-day cars.
The second, produced by RML Group’s Engineering department, is a Le Mans Hypercar-influenced Porsche 911-based project that will extend the car’s speed and handling capabilities well beyond standard, while maintaining full reliability. Known internally at RML as P39, the upgrade package is designed to work across the 911 range and includes a list of options to enhance both engine and aero performance.

Third on the list, from the company’s Power division, is RML’s high-performance VarEVolt battery module. Having proven itself around the Nurburgring, the proprietary battery technology is now being installed as a key component in a number of supercars, including a current Goodwood FoS record holder.
Rounding off the Group’s 40th anniversary product portfolio, the Bespoke department has drawn heavily on both its storied road and race history with Aston Martin to create a SuperClassic version of the original V8 Vantage. The carbon-bodied car retains all of the original’s muscular design cues but pairs them with 21st century mechanicals to create one of the world’s finest and most capable grand tourers.

“RML Group has achieved an enormous amount in the previous 40 years, we are still focused squarely on the future as these product launches show,” said third-generation CEO, Michael Mallock. “I am excited to bring all of these new high-performance products to market. They are just the beginning of a long product pipeline for us. I look forward to sharing more details on each soon.”

RML Group was founded in 1984 by Michael Mallock’s father, Ray, a successful single-seater and sportscar racer. Under his leadership the business specialised in championship-winning motorsport and precision automotive engineering.

Today, RML Group has expanded to meet the diverse needs of the automotive industry, having recently announced the appointment of former Lotus and Bentley senior executive, Paul Dickinson, to lead operations and drive growth.

From short-run manufacturing projects to continuation cars, from innovative mould-breaking racing cars to cutting-edge ultra-performance battery packs, the company has never strayed from its founding principle of Engineering Excellence.

RML Group reveals new Le Mans Hypercar-inspired P39 project!

- All-new new carbon body has active aero and DRS
- Chassis features longer wheelbase, wider track, hydraulic height adjustor
- Engine extensively tuned to produce more than 900bhp and 1,000Nm
- Projected Nordschleife lap time faster than a 992 GT3RS*
- P39 40th Special Edition limited to 10 examples worldwide

Wellingborough, Northants October 16, 2024 – RML Group Ltd, the UK’s leading high-performance engineering specialist, today unveils first production details of its bespoke P39 project.

Merging Le Mans Hypercar design and daily road-car usability, the P39 40th Special Edition (40SE) delivers an unrivalled blend of RML's championship-winning expertise and engineering excellence.

Based on the Porsche 992.1 Turbo S, the RML P39 40SE upgrades every area affecting performance, ride and handling. The net result is an extraordinary hypercar that has track capability beyond a Porsche 992 GT3 RS* yet maintains a high level of compliance and day-to-day usability.

Michael Mallock, CEO of RML Group, said: ‘What better way to showcase our leadership on road and track over 40 years than with the launch of a Le Mans Hypercar-inspired hypercar?

‘Our new RML P39 40th Special Edition challenges everything that’s possible in this sector,’ he added. ‘It will comfortably eclipse a GT3 RS* at the Nordschleife while being relaxing and easy to drive all the way home again.’

To expand the car’s handling abilities, P39 40SE’s track has been increased front and rear plus the wheelbase has been lengthened. The bodywork has been replaced by a carbon fibre shell inspired functionally and aesthetically by the new Le Mans Hypercar category.

This features front and rear active aero complete with an integrated, driver-activated drag reduction system (DRS) which reduces aerodynamic drag to boost speed on straights. Furthermore, the entire chassis can be remotely lowered to increase downforce via hydraulic actuators.

In this configuration, P39 40SE generates an extraordinary 662kg of downforce – more than 4.5 times a standard 992.1 911 Turbo S at 150mph.

Making the most of this new-found ability, P39 40SE’s twin-turbo six-cylinder engine is taken to 900bhp at 7,300rpm and 1,000Nm of torque thanks to a new ECU, upgraded turbos and intercoolers, new manifolds and catalytic converters plus a tuned Inconel sports exhaust.

Using RML’s advanced simulation software, these upgrades translate to an anticipated Nordschleife lap time of 6min 45sec*. This compares with 7min 17sec for the standard 992.1 Turbo S and 6min 49sec for the GT3 RS.

Yet as focused and stiff as it is in Track Mode to achieve this scintillating speed, P39 40SE has two distinct modes or characters. With the car in driver-selected Tour Mode, the ride height increases, damping relaxes to make the car more compliant and everyday useable.

Inside, P39 40SE celebrates RML’s 40 years of engineering excellence with new sports seats and embroidery matched with four-point safety harnesses for both driver and passenger. The standard vestigial rear seat is removed and replaced with a custom half roll cage.

The package is completed with no-cost option RML 40SE Ruby Red paintwork and bespoke forged alloy sports rims – 20in at the front and 21in at the rear.

Just 10 examples of P39 40SE will be created at RML’s engineering centre at Wellingborough, near Silverstone, with the first already under construction.

P39 40SE is delivered as a completed vehicle, with each costing £495,000 excluding taxes plus the donor car. RML can source these, as required.

You'd have to be smoking something pretty special of be half blind to be able to see how this is inspired by a LeMans hyper-car!!!

Has Mr Mallock ever been to LeMans?? If he had he would surely noted they look like this nothing at all like his oddly styled 911.

It's very safe to say the Mallocks are familiar with Le Mans.

They're plugging it because they want more involvement in LMH, beyond being a supplier to the current teams.

I don't mind this too much, given that it's not trying to be a fresh take on the retro 911 theme. It's far better than the recent slew of distasteful restomods.

 

[reefer]

Looks a bit over the top for me, but I guess some people will love it.

I know that's way he's jumped the shark trying to liken this abomination to an LMH car. I could understand 90's era GT1 but no current LMH or any protype for that matter looks like that thing.

What is the deal with 911 restomods, the latest crop all look rather vulgar. Gunterwerks, this, the Kalma Automotive pretend 959, all horrible. At least Singer haven't lost track, they are still the go to company.

I agree but, to be clear, this isn't a restomod. It's a tuner kit for 992.1

As we start the countdown to the dynamic debut of Car Zero – the P39 Hypercar development prototype – at next month’s Supercar Fest, we are revealing for the first time some of the key production details of the car. This week: drivetrain.

Working in partnership with celebrated Porsche tuning specialist, UK-based Litchfield Motors, RML Group engineers have developed a unique set of parameters which both preserve the P39’s effortless road manners but can deliver staggering track performance on demand.

Three available power levels are available via the steering wheel mode switch: Wet – offering a softer power curve and around 600hp; Normal, which raises the power output to 750hp and provides a more progressive throttle map; and Sport/Sport+ for track use. This offers Hypercar-level 920hp/705lb ft with the sharpest-possible response.

The P39’s upgraded drivetrain components are unique to the car. While the foundation is based on Litchfield’s extensive work with the 992 Turbo S, the P39 project gave the company freedom to move beyond the constraints of OEM packaging.

Michael Mallock, RML Board Member with responsibility for the Bespoke Division said: “A British powertrain partner, with engineering standards and attention to detail mirroring our own,were critical. I’m confident that the package being developed with Litchfield delivers not only class-leading performance, but great useability.”

RML Group CEO, Paul Dickinson added: “The exacting dual performance characteristics defined by our engineers have been met and even exceeded in some areas. So, we are confident the P39 will deliver on all its visual promise.”

In advance of the dynamic debut of Car Zero – the P39 Hypercar development prototype – at Supercar Fest May 17/18, we are this week revealing some of the car’s chassis insider secrets.

Using all four decades’ worth of skill and championship-winning experience, allied to the latest tech and processes, the RML Group Engineering Division has completely reworked the entire chassis and systems to create the ultimate GT car.

As much thought and care has gone into preserving the car’s ride and everyday useability as increasing the P39’s on-track abilities. For example, after widening the track by 100mm and stretching the wheelbase by 25mm, the new bespoke suspension components preserve the standard active roll bars and rear-wheel steering.

Similarly, instead of compromising the ride in Touring mode for better Track manners, a secondary spring principally designed for Track mode as been introduced to preserve P39’s compliant ride quality in Touring mode and add extra control in Track setting.

A majority of the new chassis componentry – links, top mounts, lifters (OE components in red, above) – is produced by RML’s in-house manufacturing team. The only stand-out external partnership is with British suspension experts, R53, which supplies the bespoke three-mode dampers tuned to RML specs that replace the standard units.

Michael Mallock, RML Board Member with responsibility for the Bespoke Division, comments: ‘P39 will set new performance benchmarks, no question. But, what will surprise most people is just how much of the standard car’s excellent ride quality we have managed to preserve. It really is quite striking.’

RML Group CEO, Paul Dickinson is equally confident about customer response to the car: “Many companies will make you a faster Porsche, only RML Group has the engineering expertise and experience to produce an ultimate GT like P39.”

Rollout time – the P39 Car Zero Prototype takes its first shakedown drive at Millbrook Proving Ground ahead of its public debut at Supercar Fest in Sywell on May 16/17.

Still deep in the proving process, the unpainted P39 shows off its dramatic all-new carbon fibre curves and active aero features which together help it generate more than five times more downforce than the standard car.

Visitors to Supercar Fest will have the chance to get a close-up look at the car and thrill to its signature 920bhp soundtrack as it launches up the runway.

Driving the car on its maiden run, Michael Mallock, RML Board member and Bespoke Division head, comments: ‘The speed and handling of the car, even in this early form, is next level. I’m delighted with the results and thrilled we can share the car with the public for the first time at Supercar Fest.’

 

[Jonathan19]

Ahead of @rmlgroup’s P39 public debut at Supercar Fest at Sywell this weekend, I wanted to share some photos I took during the build.

The P39 has received extensive upgrades over the base vehicle, but these images focus specifically on the suspension changes. You can tell the RML design from the original by the black linkages.

The track has been widened by 100mm, and the wheelbase extended by 25mm. New, custom-designed suspension components have been introduced to retain the standard active roll bars and rear-wheel steering.

Rather than compromising the comfort of Touring mode for improved performance in Track mode, a secondary spring has been added. This allows the P39 to maintain its refined ride quality in Touring mode while delivering enhanced control in Track mode.

I can’t wait to see the car in action this weekend.

RML Group P39 hypercar prototype debuts at Supercar Fest

• RML P39 hypercar prototype breaks cover at Supercar Fest 2025
• Spectators and customers stunned by P39’s supercar-eclipsing performance
• 920 horsepower and 6,500N of downforce for unrivalled road-to-track versatility
• RML development engineers amass valuable data as first customer car remains on track for late summer delivery
• P39 confirmed for starring role at Silverstone Festival, Aug 22-24

Wellingborough, Northampton, 22 May 2025 – RML Group, the British engineering firm renowned for four decades of motorsport and engineering innovation, wowed spectators at Supercar Fest The Runway 2025 with the first public appearance of its limited-edition P39 hypercar prototype.

The event, based around top speed and repeated full-throttle acceleration runs, is staged annually at Sywell aerodrome, near Northampton. It provided the perfect opportunity for RML to show the car in public for the first time.

Conceived to celebrate RML Group’s 40‑year milestone, the P39 transforms the already‑formidable Porsche 992.1 Turbo S platform into a hypercar that retains its daily usability with new, uncompromising circuit capability.

The next opportunities to see the P39 prototype run in the UK are at the Supercar Driver Secret Meet at Silverstone, June 17 and then the Silverstone Festival, August 22-24.

Aerodynamics: Active Intelligence Meets Supreme Downforce

From nose to tail, the P39’s bodywork has been re‑sculpted in carbon fibre and laced with active aero devices that completely recalibrate the Turbo S’s performance envelope. An electronically controlled rear wing hides its second element in Road mode, then elevates and pivots in Track mode to create a slot gap that boosts rear wing downforce by 24 percent. A driver‑selectable Drag‑Reduction System (DRS) can flatten the element, trimming drag by 23 percent for maximum velocity on straights.

Up front, an extending splitter slides 75 mm forward in Track mode, increasing surface area and moving the centre of pressure nose‑ward to sharpen turn‑in. Complementary airflow management – including air curtains around the front wheels, fender cut‑outs, an under‑body diffuser and vented rear arches – raises overall downforce from the Turbo S’s stock 1,432N to 5100N in Road mode and more than 6,500N in Track mode at 150 mph. These figures place the P39 firmly in competition with purpose‑built GT racers while preserving ride quality in road mode.

Chassis: Wider, Lower, Faster – Yet Remains Civilized

To exploit this newfound aerodynamic grip, RML engineers re‑imagined the chassis from the hubs inward. New suspension links widen the track, bespoke top mounts preserve ideal camber angles, and secondary springs increase wheel rates in Track mode without destroying ride quality on the road. Bespoke R53‑supplied dampers, tuned by RML, give the driver three cockpit‑selectable settings, while a four‑corner hydraulic lift system provides two rear and three front ride‑height options for everything from speed‑bumps to pit‑lane.

The anti‑roll hydraulics and rear‑wheel‑steer system have been recalibrated for the P39’s lower stance, wider track and longer wheelbase. Bespoke alloys – 20X10 inches up front, 21X12 inches at the rear – wear customer-specified tyres.

Powertrain: Three Personalities, One Huge Heart

Beneath the rear deck, the twin‑turbo flat‑six has been the subject of an exhaustive re‑engineering programme in partnership with Litchfield Motors. Larger‑diameter intake and exhaust plumbing, a unique Inconel exhaust valve – the largest ever fitted to a road‑going flat‑six – and optimised thermal routing lift output to 920 horsepower and 705 lb‑ft of torque in Sport/Sport + mode. Two additional presets give the powertrain dual personalities: a 600‑hp Wet mode for low‑grip conditions and 750‑hp Normal mode for fast road driving. All bespoke components carry a 12‑month/12,000‑mile warranty, while over‑the‑air diagnostics and calibration updates ensure the P39 evolves with its owner.

Leadership Perspective

Michael Mallock, Board Member responsible for RML’s Bespoke Division, comments:
“From the outset we set ourselves the challenge of building a car which could switch personalities at the touch of a button – serene on the road, savage on the circuit. The numbers speak for themselves, but what excites me most is how intuitive and confidence‑inspiring the P39 feels, whatever the setting.”

Paul Dickinson, Chief Executive Officer of RML Group

“P39 is a rolling demonstration of what RML’s Engineering Division can achieve. By integrating active aerodynamics, a re‑imagined chassis and a 920hp powertrain, we have created a hypercar that delivers relentless track performance yet remains perfectly at home on the King’s Road. It is the purest expression of 40 years of engineering excellence, distilled into a car that wears our badge with pride.”

Availability

The P39 will be built in a strictly limited run of 39 cars. First UK customer deliveries are scheduled for late summer 2025 following final tuning and validation testing. A full spectrum of bespoke options is available.

P39 Sales and aftercare agents have been appointed in the US and Europe.

I respect RML and I fully expect this to be a beast on track. But there's just something off about the way it looks. Having seen bunch of P39 instagram posts from Supercar Fest, the car just looks very tall next to your typical supercars. And the fact they added roof scoop and deleted rear window only exacerbates the visual mass issue.

Not to say that P39 is strictly GT1 inspired, but I think 992 Turbo shell lends itself to 959-style conversion much more naturally than to GT1 homage style. M.P. Gemballa Marsien looks just about perfect (despite the lifted suspension), whereas RML P39 looks nothing like GT1, simply because it lacks the most important visual character trait of GT1 - the lowered roof line.
To do it justice, they would have to start with Speedster shell, just like Porsche did with the original GT1. No doubt this would be needlessly complicated... So if it was up to me, I'd drop the GT1 pretense entirely, and lose the roof scoop +retain the rear window.

Apologies for missing photo credits, I downloaded these a while back and CBA to track down the sources.
