With peak output of 280 kW (381 hp) and a maximum torque of 475 Nm, the Mercedes-AMG A 45 4MATIC (W 176) is the world's most powerful compact sports model. The revised gear ratios, aerodynamic fine-tuning and the new DYNAMIC SELECT driving modes raise overall performance to a higher level, underlining the claim to leadership in this market segment. The compact saloon absolves a sprint from standstill to 100 km/h in 4.2 seconds, 0.4 seconds faster than the preceding model. Maximum traction also on tight bends is ensured by the standard all-wheel drive and the optional front axle differential available for the first time. At the same time fuel consumption has remained as before: no other high-performance model in this class can better its NEDC fuel consumption from 6.9 litres per 100 kilometres (corresponding to 162 g/km CO2)..
