Even the most recent BMW M3 with its 420HP V8 engine can't escape from the tuning claws of G-Power. However, if you've been following the latest news from the German tuning firm, you will probably be surprised with the somewhat modest upgrades that G-Power has incorporated into the M3 Coupe Tornado. The most significant change concerns the addition of tailor-made 'light' supercharger from ASA with a moderate 0,3 bar boost. Along with a new intercooler and a performance exhaust system, the 4.0-liter V8's output increases from 420HP and 400Nm to 500HP and 480Nm (354-lbs/ft). 
G-Power says that the supercharged M3 Coupe with the 6-speed manual gearbox can accelerate from standstill to 200km/h (124mph) in just 13.5 seconds compared to the standard M3's time of 15.8 seconds. Customers can opt for the removal of the electronic speed limiter, in which case the M3 Coupe Tornado can reach a top speed in excess of 320km/h or +199mph..
The M3 Coupe Tornado also comes with a height-adjustable coil-over suspension with nine selectable settings each for bound and rebound while the car rides on Michelin Pilot Sport tires -255/30 ZR20 in front, 295/25 ZR20 in the rear- mounted on lightweight 20-inch Silverstone alloy wheels. The kit is complemented by a new four-pipe muffler made from stainless steel or optionally, from titanium which is 14,5kg or 32-lbs lighter than the factory part.
Unlike other G-Power models like the M6 Hurricane CS and the X5 Typhoon, the M3 Coupe Tornado does not feature any exterior upgrades other than the rims. The German firm does however update the interior with carbon-fiber trim, a new speedometer with the G-Power logo, an aluminum pedal set and optionally, a special leather treatment.
