What a weapon THIS IS GOING TO BE!
Dynamism made in Affalterbach: the AMG chassis engineering
The outstanding agility and racetrack-ready driving dynamics of the four-door AMG GT are also down to the special AMG suspension. On the six-cylinder model a suspension with steel springs and adjustable damping is used as standard. The suspension on the eight-cylinder variants is based on the fully load-bearing multi chamber air suspension AMG RIDE CONTROL+. A rigid integral carrier bears the front axle, engine, transmission and steering gear.
In conjunction with the wide track width and the configuration for large tyre dimensions, wheel location and spring elements which are independent of one another facilitate high lateral acceleration, whilst the low unsprung masses promote the agile driving feel yet further.
The rear axle differential also has a new specially reinforced mount to improve the NVH (noise, vibration, harshness) characteristics. As on the AMG GT R, an anti-roll bar made of tubular material reduces the overall weight of the rear axle.
Intelligent all-wheel drive: AMG Performance 4MATIC+
All AMG GT 4-Door Coupé models are equipped with the AMG Performance 4MATIC+ all-wheel drive. An electro-mechanically 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.
It is still possible to drift thanks to fully variable torque distribution. The Drift Mode is suitable for this; in the S version of the four-door AMG GT it is standard, and in the other models it is available as an option. This can be activated in the "RACE" drive program using the shift paddles, provided that ESP® is deactivated and the transmission is in manual mode. When activating the Drift Mode the four-door sports car thus turns into a model with purely rear-wheel drive.
Enhanced agility and precision: the active rear-wheel steering
The AMG GT 4-Door Coupé responds even more sensitively to steering commands thanks to the active rear axle steering which comes as standard in the V8 models and is optional in the six-cylinder versions. The system facilitates an even better combination of agility and stability and thus reinforces the dynamism and the handling safety of the new AMG GT four-door model.
Up to a speed of 100 km/h, the rear wheels point in the opposite direction to the front wheels via two electric actuator motors. As a result, the car turns into corners with significantly higher agility. Under everyday driving conditions, the driver also benefits from a smaller turning circle.
At speeds higher than 100 km/h, the system turns the rear wheels in the same direction as the front wheels. That noticeably improves driving stability. At the same time, the lateral force on the rear wheels builds up considerably faster on changes of direction, thus improving the response to the steering. The driver can also rely on extreme rear-axle grip and high stability when changing direction quickly, without the usual tendency for the rear end to break out.
Yet more differentiation in driving experiences: AMG DYNAMICS
Depending on the engine there are up to six drive programs to choose from in the four-door AMG GT: "Slippery", "Comfort", "Sport", "Sport+", "RACE" and "Individual". These levels are selectable via the gearshift paddle in the centre console and stored with the new drive program attribute AMG DYNAMICS, which can be adjusted to match the AMG GT 4-Door Coupé's handling characteristics to different demands and driving conditions in a much more differentiated way.
Behind the umbrella term AMG DYNAMICS are the agility functions "Basic", "Advanced", "Pro" and "Master", which are automatically selected by the respective drive program. Parameters relevant to driving, such as the response of the engine, suspension, the control strategy of the all-wheel drive system and the control thresholds of the completely redeveloped ESP® are intelligently adapted according to the drive program.
The spectrum ranges from extremely safety-oriented to highly dynamic. The "Master" mode stored in the drive program RACE ensures optimum agility and brings out the high driving dynamics potential of the new member of the AMG GT family to optimum effect - for example 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 on the all-wheel drive system.
