Despite the massive power, the new 5.5-litre V8 - which replaces the 6.3-litre AMG of old - gives 7.4mpg more than before, and emits 29 per cent less CO2.
Drive-it-like-you-stole-it and you'll notice the AMG's standard fit Direct-Steer and torque vectoring brake systems, the latter of which gently applies the brake on the inner wheel when cornering.
