BMW M6 Gran Coupe by G-Power
With a 560 PS twin-turbocharged
V8, pushing it from standstill to 100 km/h in 3,7 seconds, the BMW M6 Gran
Coupe is already a very powerful, potent, gentleman’s GT. Even so, G-Power
still thought it needed a little bit of oomph.
With an expertise in tuning spanning
over three decades, the German company had no problem bumping the M6’s power
output to ginormous proportions, offering packages ranging from 650 PS all the way to 740 PS.
True, this output is not something
unheard of in this day and age, but lately, car makers and car tuners alike,
throw horsepower values around like it’s nothing, even though an overpowered
four-door sporty limousine is more than you can ask for.
The most modest power upgrades for the
S63 V8 engine were made for as an easy installation, plug-and-play solution for
customers around the world, but if somebody wants to give it the full beans,
then a little more than a remap is required.
A first step is a reduction in exhaust
backpressure, using gas-flow optimized steel downpipes, with (or without) 200
cell catalytic converters. This helps the plug and play remap to achieve 700 PS and 905 Nm of torque, but the most powerful tuning stage is reached by
adding a full-length titanium exhaust system, weighing 10.5 Kg less than the
standard variant, with titanium link pipes and quad tailpipes.
The result? A 740 PS, 975 Nm
machine that sprints from 0 to 200 Km/h in 10.5 seconds, stopping from
accelerating at 325 Km/h.
In charge of putting the power to the
asphalt are a set of ultra-light aircraft grade aluminum, the G-POWER Hurricane
RR 9.0x21-inch and 10.5x21-inch forged alloy wheels.
