As Mercedes-AMG’s
second standalone model after the SLS, the GT is a tremendous sports car,
particularly in range-topping R guise. With 585 PS and 700 Nm of torque produced by a twin-turbocharged 4.0-liter V8 engine, the
Mercedes-AMG GT R is probably the closest thing to a German muscle car. Few
people would feel the need for a faster machine, the GT R goes from
0 to 100 km/h in 3.6 seconds and has a top speed of 318 km/h.
Still, the folks
from G-Power wanted to extract even more performance from the AMG GT R. The
aftermarket specialist offers four different options for increasing the V8’s
peak output, culminating in an 800 PS variant that also comes with a
maximum torque figure of 850 Nm.
The extra oomph is
achieved via a combination of the Performance Software V4 and several hardware
modifications to the M178 motor. Those include a racing fuel pump,
weight-optimized forged pistons with reduced compression, modified
turbochargers with larger turbine and compressor wheels, as well as
CNC-optimized housings and enhanced compressor turbine blades. The intake
system with sports air filters and downpipes with sports catalytic converters
are also new.
To cope with the
additional 215 PS and 150 Nm of torque, G-Power engineers have also
reinforced the seven-speed dual-clutch automatic transmission. If a 789 hp
output sounds too extreme, G-Power also offers the Performance Software V3
combined with the same hardware modifications for a total of 750 PS and 800 Nm of torque.
Further down the
ladder is the Performance Software V2 which takes the 4.0-liter V8 power plant
to 690 PS and 770 Nm of torque in combination with flow
optimized downpipes. Finally, the entry-level Performance Software V1 comes
with a still satisfactory 650 PS and 750 Nm of torque. Each
of the aforementioned power kits can be had with Hurricane RR forged aluminum
rims shod with 275/30 ZR20 Michelin tires at the front and 305/25 ZR21 rubber
at the rear.
