For more than 35 years the brand G-Power has stood for optimized BMWs with extraordinary performance values. The fitting platform is traditionally mostly one of the top models, which are built in the hallowed production halls of M GmbH. This was also the case for the latest creation by the G-Power specialists, headquartered in the Swabian part of Bavaria. The G-Power G8M Bi-TURBO is based on the equally sporty and luxurious M8 Competition Cabriolet.

In its standard production version, the open Gran Turismo already features the extremely powerful S63B44T4 eight-cylinder engine with an output of 625hp and 750Nm. It is even more brutishly powerful following transformation to the G8M Bi-TURBO – with a whopping output of 820hp (603kW) and 1,000Nm torque! To achieve these values, G-Power relies on a combination of software and hardware upgrades and on the one hand installs the GP-820 performance software, which includes individual, optimized programming of the maps on the factory engine control unit.

On the other hand, upgrade turbochargers with a larger compressor wheel plus improved turbine wheel and CNC-milled housings, downpipes with or without sports catalytic converters that reduce exhaust gas back pressure, and a titanium exhaust system are used. The latter produces a rousing sound backdrop that is even reminiscent of motorsport vehicles. The tailpipes are carbon-tipped. The 820hp version is the most powerful performance upgrade for the M8, and two further upgrades are available. The entry-level upgrade is the increase to 720hp (529kW) and 850Nm, which is achieved exclusively via the GP-720 performance software. In between is the version with 770hp (566kW) and 930Nm, in which case the BMW gets the GP-770 performance software and the downpipes with sports catalytic converters. The G-POWER G8M Bi-TURBO stands out visually thanks to its HURRICANE RR forged wheels. The lightweight, ultra-strong twin-spoke wheels boast a 21-inch format, a black diamond cut finish and Michelin tires in the sizes 285/30ZR21 and 295/30ZR21.
