One of the world’s fastest and most powerful convertibles is made by G-POWER. The 335-km/h G-POWER M6 HURRICANE is based on the latest BMW M6. At the heart of the high-performance convertible is a five-liter V10 engine with G-POWER BI-Kompressor system that delivers 635 hp / 467 kW.
To achieve the desired increase in power output of 128 hp / 94 kW for the fast-revving engine that normally produces 507 hp / 373 kW, G-POWER has developed a high-tech supercharging system. The system uses one belt-driven ASA T1-12 compressor for each cylinder bank. Contrary to conventional mechanical chargers that waste a large portion of the additional power on being driven themselves, the ASA compressor has an efficiency rate of up to 80 percent. The ASA charger is also small, which allows G-POWER to install two of them in the tight confines of the M6 engine bay. With a maximum airstream volume of up to 1,200 kg per hour per cylinder bank the compressors are designed for an even higher power output than the limited boost pressure of 0.4 bars featured at the M6 HURRICANE convertible. In comparison. The G-POWER M5 V10 HURRICANE based on the BMW M5 with a boost pressure of 0.7 bars is producing 730 hp and holds the record for the fastest street legal BMW with a top speed of 360 km/h.
The pre-compressed charge air is cooled down in a highly efficient dual-flow water-to-air intercooler system that is mounted above the engine. This measure optimizes power yield, throttle response and also ensures the engine’s thermal health. Specially developed mapping for engine electronics and SMG gearbox controls coordinate the perfect interaction of all new components.
The supercharged M6 V10 engine produces its maximum power output of 635 hp / 467 kW between 7,500 and 8,200 rpm. The high efficiency rate of the two ASA superchargers, each spinning at up to 100,000 rpm and more, results in a torque diagram that rises early and at 4,800 rpm already surpasses the production engine’s peak torque of 520 Nm, delivered at 6,000 rpm. The new peak of 600 Nm is reached at 7,200 rpm. This special characteristic is, apart from the outstanding reliability and long life qualities, the reason why ALPINA features the ASA superchargers in their models B5, B6 and B7, as well.
Acceleration performance benefits from the perfect performance characteristic accordingly. With a sprint time from rest to 100 km/h of 4.6 seconds and to 200 km/h in 11,9 seconds the 2-ton convertible accelerates like a true sports car. The 300-km/h barrier is shattered after 34,5 seconds from standstill. Contrary to the production car the G-POWER HURRICANE is not limited electronically to a top speed of 250 km/h but to 320 km/h. The determining factors therefore are weight, tyres and most important the soft top of the M6 convertible.
