More power. Less fuel. That's the bare bones of the latest V8 equipped Mercedes AMG performance model – the E 63 AMG. The car's 5.5 liter biturbo V8 gives it a peak output of 386 kW (525 hp) and torque of 700 Nm – add on the optional AMG Performance package and it jumps to 410 kW (557 hp) and 800 Nm. Acceleration is specced at zero to 62 mph (0-100 km/h) in 4.2 seconds, top speed is 155 mph (250 km/h - electronically limited) and fuel consumption is down almost a quarter on its naturally aspirated predecessor at 24 mpg (9.8 liters per 100 kilometers). Needless to say, there's some impressive tech underlying these figures.
