G-Power has created one of the fastest BMW's in the world with the M5 Hurricane. At the heart of the high-performance sedan is a five-liter V10 engine with G-POWER EVO II supercharging system that delivers 730 hp. To achieve the desired increase in power output of 223 hp for the fast-revving engine that normally produces 507 hp, G-POWER, in cooperation with ASA Automotive, 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 M5 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. Boost pressure is limited to 0.5 bars.
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 and, in combination with a larger water-cooled oil cooler with pressure reservoir, 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 inner workings of the four-valve ten-cylinder engine are optimized for even higher engine speeds with lightweight, precision-matched high-performance forged pistons from technology partner MAHLE. The supercharged V10 engine produces its maximum power output of 730 hp between 7500 and 8200 rpm. The high efficiency rate of the two superchargers, each spinning at up to 100,000 rpm and more, results in a torque diagram that rises early and at 3800 rpm already surpasses the production engine’s peak torque of 384 lb-ft, delivered at 6000 rpm. The new peak of 517 lb-ft is reached at 7200 rpm.
Acceleration performance benefits accordingly. With a sprint time from rest to 0-60 mph of 4.1 seconds the two-ton sedan bests its production counterpart by half a second. With approx. ten seconds to 200 km/h the advantage grows to 5.0 seconds. The 300-km/h barrier is shattered in less than 29.5 seconds. Contrary to the production car the G-POWER HURRICANE is not limited electronically to a top speed of 250 km/h. Aided by the specially cooled G-POWER anti-slip differential the engine propels the car to an electronically-limited top speed of 211 mph.
Meanwhile the maximum speed exceeds the limits of the OEM tires. Testing found special high-speed tires of the Continental that allow a speed of more than 217 mph. Further aerodynamic adaptations allow an even higher theoretical top speed.
The G-POWER front apron is made from especially light carbon fiber and replaces the production part in its entirety. Its large air inlets provide optimal supply of cooling air for all radiators and front brakes. At the same time the spoiler minimizes lift on the front axle at high speeds.
The G-POWER rocker panels smooth the airflow between the wheel houses and give the M5 and longer, lower and sleeker appearance. Lift on the rear axle is reduced by a spoiler lip attached to the trunk lid and the carbon-fiber rear diffuser for the G-POWER rear apron.
Even better driving dynamics and more exclusive looks are the hallmark of the G-POWER Silverstone 21-inch light-alloy wheels that fill out the space beneath the wheel arches perfectly. The drop-center rims have brilliant-graphite coated centers while the outer rim wells and spokes are polished. They are mounted in sizes 9.5 J x 21 with size 255/30 ZR 21 tires in front and size 10.5 J x 21 wheels with size 295/25 ZR 21 tires on the rear axle. Technology partner Dunlop provides the perfect high-speed tires.
The large wheels make room for the G-POWER high-performance brake system with six-piston fixed calipers and 400 x 36 millimeter brake discs on the front axle. G-POWER also offers an upgrade package for the standard M5 brakes that consists of high-performance pads and brake fluid.
The M5 handling can be made even sportier by installing the height-adjustable G-POWER coil-over suspension RS with nine selectable settings each for bound and rebound.
For upgrading the cockpit G-POWER offers sporty components made from exposed carbon-fiber trim or an ergonomically shaped NARDO EDITION sport steering wheel covered in perforated G-POWER Kjerba-Nappa leather that is a pleasure to touch.
The G-POWER HURRICANE is available as a fully converted car starting at 300,000 Euros. Any existing M5 – sedan and wagon – can also be upgraded with the G-POWER twin-compressor system. The price includes all necessary modifications to suspension, brakes and wheels. Also available are any items from the extensive G-POWER tuning accessories lineup.
