Mercedes-AMG continues to champion performance, dynamism and efficiency: the new Mercedes-Benz E63 AMG is now available as a particularly powerful S-Model with an output of 430 kW / 585 hp, 800 Newton metres of torque and featuring a newly developed performance-oriented AMG 4MATIC all-wheel-drive system. The AMG 5.5-litre V8 biturbo engine continues to be the absolute pinnacle of efficiency: the combination of high performance and low fuel consumption remains unrivalled by any other competitor in the segment worldwide. The permanent all-wheel drive is also optionally available for the other E63 AMG models - on which the V8 engine has been uprated from 386 kW / 525 hp to 410 kW / 557 hp, with 720 Nm of torque. With this range, Mercedes-AMG is premiering high-performance passenger car models with an all-wheel-drive system geared to driving dynamics.
