The
G63 is powered by Mercedes-AMG's well-known 4.0-litre twin-turbo engine
which, in this application, delivers a stonking 430 kW (at 6 000 rpm)
and 850 Nm of torque from 2 500 to 3 500 rpm. It is mated with the
marque's 9-speed automatic transmission that duly impressed with its
immediacy and slickness during the G63 Edition 1's tenure in our test
fleet. At this point, it's worth noting the G63's kerb weight (around
2.5 tonnes) and the fact that it retains the brick-like aerodynamics (at
face-value, anyway) of its predecessor. It's worth pointing these facts
out because they provide such great context for the figure that follow.
