G-Power BMW M5 Hurricane RRs
After the G-POWER M5 HURRICANE RR with twin-supercharger engine and 800 hp/588 kW has set a new High-Speed record with 372 km/h in 2010, improving the old G-POWER record from 2008, the demand for this power sedan with supercharged V10 engine just exploded. So, today already the 100th G-POWER HURRICANE is leaving the G-POWER workshop in Autenzell as a jubilee model with an additional 30 hp output increase.
This light blue G-POWER M5 HURRICANE RRs is equipped with a reworked version of the high-revving V10 engine modified by G-POWER and supercharged by a BI-Kompressor "Sporty Drive“ system. Therefore the two superchargers named ASA T1-313 have been replaced by larger ASA T1-316 units. They are both driven by a belt and do provide each cylinder bank with supercharged air. Further down the line the pre-compressed air from the superchargers is cooled for a maximum power output. A complicated aluminium casting - painted in G-POWER orange - replaces the standard air box on top of the engine, and its direct inlet is responsible for the spontaneous response characteristics which give the G-POWER motor its incomparable response and also much more torque.
The inner workings of the 10-cylinder, four-valve engine are optimised by light, precisely balanced MAHLE high-performance forged pistons with lower compression and increased mechanical strength. As the standard connecting rods and piston pins were equally not up to the considerably increased forces, here too, recourse was had to special parts. The switch to an Alpha-N engine management system and hence the elimination of the air mass sensors also contributes to the increased power output of 830 hp / 610 kW, available between 7,500 and 8,000 rpm. The engine delivers its peak of torque of 780 Nm at 6,500 rpm.
Of course the periphery of the engine, especially the exhaust system and the fuel supply system, needs to be modified as well in order to match with the new requirements. A G-POWER SPEEDFLOW exhaust system with two racing catalysts minimizes the exhaust backpressure and a G-POWER stainless steel rear muffler with DEEPTONE technology and 4 x 83 mm tail pipes featuring the M-Design completes the exhaust system of the M5 HURRICANE RRs. The capacity of the fuel supply system is upgraded with fuel injectors with enlarged mass flow and the use of an additional high performance fuel pump. An electronic control unit designed by G-POWER enables the additional third fuel pump to operated boost related. This set up guaranties and reliable fuel supply under all conditions.
Prepared like this the G-POWER HURRICANE RRs does not only set new performance standards for top speed. With an acceleration of just 4.3 seconds from standstill to 100 km/h, 9.1 seconds from standstill to 200 km/h and 25.2 seconds from standstill to 300 km/h the two-ton sedan is also leading his class.
Two tons of weight and a top speed of more than 370 km/h naturally require extreme demands on the tires, being fitted on special G-POWER wheels. Our technology partner Michelin provided high-performance Pilot Sport tires in the dimensions 255/35 ZR 19 at the front axle and 305/30 ZR 19 at the rear axle for this reason. For every day use the G-POWER HURRICANE RRs runs on 20-inch SILVERSTONE DIAMOND wheels with the dimensions 255/35 ZR 20 and 285/30 ZR 20 front and rear.
Even more contributions to the HURRICANE RRs’s high-speed talents are coming from a height-adjustable G-POWER RS coilover suspension that is adjustable for both compression and rebound in nine settings and the high-performance G-POWER brake system with up to six brake pistons and up to 396 mm brake disc diameter for the front axle and 380 mm for the rear axle. The G-POWER brake system enables a substantially higher brake force than the standard brake system. At the same time, the heat generated due to the braking process can be dissipated more effectively. The G-POWER brake package is completed by brake pads with a larger pad area, higher friction rate as well as metal-coated brake lines. With this set-up, the G-POWER Braking System always provides maximum brake force and the braking point remains precise in any case. Of course, G-POWER customers are provided with the choice of rotor material: both steel brake discs and ceramic alternatives (which are about 50% lighter for significantly improved cornering and road handling) are available.
