Mercedes-Benz Releases A V8 GT 63 4MATIC+
AMG 4.0-litre V8 GT biturbo engine with two twin-scroll turbochargers
At market launch, the new AMG GT Coupé will be launched with two performance levels of the AMG 4.0-litre V8 biturbo engine. The engines are assembled entirely by hand at the company’s site in Affalterbach according to the “One Man, One Engine” principle.
In the top model GT 63 4MATIC+, the engine delivers 585hp and provides a maximum torque of 800Nm over a wide engine speed range from 2,500 to 4,500 rpm.
Accelerating from 0 to 100km/h takes just 3.2 seconds, and the top speed is 315km/h. In the GT 55 4MATIC+ (combined fuel consumption 14.1 l/100 km, combined CO2 emissions 319 g/km), the V8 unit develops an output of 476hp and a maximum torque of 700Nm. The sprint from zero to 100km/h takes 3.9 seconds, and the top speed is 295km/h.
For use in the AMG GT Coupé, the engine received a new oil pan, repositioned intercooler, and active crankcase ventilation. The inlet and outlet ports have been optimized for more effective gas exchange and the exhaust gas routing for the catalytic converter box and Otto particle filter has been enlarged.
The developers achieved the additional output of the AMG GT 63 4MATIC+ Coupé primarily through higher boost pressure and greater air throughput as well as modified engine software.
All in all, the eight-cylinder impresses with its extraordinary power development with powerful boost in all engine speed ranges, combined with the highest possible efficiency for low consumption and emission values.
Manufacturing digital and smart: “One Man, One Engine”
The engine is assembled entirely by hand. In the AMG engine factory at the Affalterbach site, the “One Man, One Engine” principle is linked to Industry 4.0 production methods. This is designed according to modern knowledge of ergonomics, the flow of goods, quality assurance, sustainability, and efficiency.
Smart production is characterised by maximum flexibility, is transparent and highly efficient. In doing so, it secures and increases the quality of the engines and the production processes with digital technologies.
Wet starting clutch for the transmission
The AMG SPEEDSHIFT MCT 9G transmission combines an emotional shift experience with extremely short shift times and is specially tailored to the requirements of the new AMG GT Coupé. A wet starting clutch replaces the torque converter. It reduces the weight and, thanks to its lower mass inertia, optimises the response to commands from the accelerator pedal, especially when sprinting and changing loads.
More traction and driving stability: fully variable AMG Performance 4MATIC+ all-wheel drive
The two V8 models are equipped as standard with the fully variable AMG Performance 4MATIC+ all-wheel drive. The intelligent system combines the advantages of different drive concepts: The fully variable torque distribution on the front and rear axle not only ensures optimum traction at the physical limit.
The driver can also rely on a high level of driving stability and driving safety under all conditions: on dry roads as well as on wet or snowy roads. The transition from rear to all-wheel drive and vice versa takes place continuously, based on a sophisticated matrix that integrates the intelligent control into the overall vehicle system architecture.
An electromechanically controlled clutch variably connects the constantly driven rear axle with the front axle. The best possible torque distribution is continuously calculated depending on the driving situation and the driver’s wishes.
The new coupé can be driven in a continuously variable manner from traction-oriented all-wheel drive with 50:50 power distribution to the front and rear axles to pure rear-wheel drive. In addition to traction and lateral dynamics, the all-wheel drive also improves longitudinal dynamics for even more powerful acceleration.
