Brabus launched a power kit that took the Mercedes-AMG E63 S to almost
hypercar-levels of performance.
G-Power’s “answer” a similar upgrade that solves the E63 S’ “power
deficit”: can you imagine having to live with “only” 612 PS and 850 Nm at your disposal? Joking aside, the tuner didn’t have to look too
far to find a Brabus-rivaling upgrade.
That’s because they
have been offering a serious power kit for Mercedes-AMG’s 4.0-liter twin-turbo
V8 for quite a while now. Launched in the C63 S in October, the upgrade boosts
the eight-cylinder engine by 188 PS and 150 Nm to an
impressive 800 PS and 1,000 Nm of torque.
The pumped-up E63 S
will shoot to 100 km/h from a standstill in just 3.1 seconds before maxing out
at more than 300 km/h. In order to achieve those significant power
and torque gains, G-Power extensively modified the engine’s hardware and
software. Responsible for the electronic tuning is the Performance Software V3,
which remaps the ECU while leaving the engine protection functions and
diagnostic capabilities unaffected.
The key hardware
upgrade is the modification of the turbochargers, which include CNC-machine
cases and aero-optimized turbine wheels. As a result, G-Power claims the turbos
“deliver incomparably better performance compared to the series components.”
Other changes consist of the addition of stainless steel downpipes (including a
catalytic converter) and a stainless steel exhaust system.
Rounding off the
tuned Merc, which you can check out in the following video, is a set of 21-inch
Hurricane RR alloys with a jet black diamond finish. In all other respects, the
E63 S looks rather understated and features only minor changes such as the
black window frames, mirror caps and boot lid spoiler and the black badging.
