2011 G-Power BMW M5 Hurricane GS

The outcome is the G-POWER M5 HURRICANE GS equipped with one fully sequential five-cylinder LPG system per cylinder bank. The benefits of LPG as a fuel are both economical and ecological in nature – not only is LPG around 50% less expensive per litre than petrol, it also reduces CO2 emissions by around 15 percent.

That said, there can be no sacrificing the hallmark G-POWER performance increase. 660 hp and 650 Nm of torque are the figures achieved by the SK II bi-supercharger system thanks to low-pressure forced induction with a relative charge pressure of 0.6 bar. Each cylinder bank of the 5.0l V10 power plant is equipped with a belt-driven ASA T1-313 compressor. Compared with conventional mechanical superchargers, which consume a large proportion of the additional power generated to drive themselves, ASA compressors have an efficiency rating of up to 80 percent. They thus form the ideal foundation for efficient forced induction, as well as increased output with an eye on resource conservation.
Downstream of the two ASA compressors, the pre-compressed charge air is brought down to performance enhancing temperatures by the twin-scroll, water-cooled intercooler finished in G-POWER’s characteristic orange. This sophisticated cast aluminium component replaces the series production airbox above the engine, where its short airways facilitate the same spontaneous responsiveness as the series production engine, albeit combined with a considerable benefit in torque. The superiority of the G-POWER compressor system is particularly evident when it comes to low-end torque, which is one weakness in the high-revving concept favoured by M GmbH. At long last, the 5.0l V10 offers impressive power delivery, of the kind that many customers might reasonably have expected from the series production version. Specifically developed mapping of the engine electronics and SMG transmission control ensure perfect interaction of all components.
urther contributors to the high-speed capability of the HURRICANE GS are the G-POWER high-performance braking system and the G-POWER RS coil-over sports suspension, with 9-way adjustability for compression and rebound plus infinitely variable height adjustment.
The G-POWER SK II bi-supercharger system incl. conversion to LPG is also available for the current BMW M5 and M6. The G-POWER SK II bi-supercharger system for 660 hp / 485 kW incl. conversion to LPG is offered for EUR 33,571.43 (net) excl. installation. The 20-inch G-POWER SILVERSTONE CLUBSPORT forged wheel set has a list price of EUR 7,635.13 (net).
