As far as we know, no one has ever complained about the M6’s performance.
We reckon it’s because its twin-turbocharged 4.4-liter V8 with 575 hp and 501 lb-ft is more than enough, even to putting some not-so-old supercars on notice.
Ah, but there’s never too much thing as too much power, or else tuning companies would go out of business, nothing is ever too good .
This particular package comes courtesy of small firm Noelle Motors. Developed for the German coupe or, as is the case here, convertible, the Stage 3 performance kit sees the installation of custom exhaust downpipes, free-flowing sport metal catalytic converters and an optimized ECU. These relatively minor changes see horsepower soar to 766 hp and torque to a massive 880 Nm (650 lb-ft).
While Noelle Motors hasn’t posted performance numbers, it has removed the factory 250 km/h (155 mph) top speed limiter and claims it can top out at 345 km/h (214 mph).
If customers want the extra performance to go with a louder roar, they can opt for a stainless steel sports exhaust and if they wish to further improve handling and grip, a set of coilovers and a range of aftermarket wheels and tires are also available.
