Following up on a BMW M5 powered by a G-Power twin-compressor engine with 730 hp /537 kW, which a few months earlier had set the record for the 'world's fastest BMW sedan' at 360 km/h, G-Power now took the next logical step, breaking the existing record for fastest sedan overall (Brabus Rocket, 365.7 km/h). With this goal in mind, development began on a new evolutionary Hurricane RS stage with 750 hp.
For this stage, the twin compressor system of the fast-revving V10 was redesigned again. Both belt-driven ASA T1-313 superchargers, each providing charge air for one cylinder bank, were replaced by larger ASA T1-316 models. They have the capacity to increase the volume of charge air by up to 25 percent but only a fraction of that was utilised in this engine. The air volume these chargers are capable of would theoretically be sufficient for a rated power output in excess of 900 hp.
The pre-compressed air from both superchargers is cooled for maximum power yield in a dual-flow water-to-air intercooler painted G-Power orange. This cast-aluminium component replaces the stock airbox above the engine. Because of its close proximity to the engine it produces the same instant throttle response as the production engine, albeit with considerably more torque.
The inner workings of the ten-cylinder four-valve engine are optimised with forged high-performance pistons from Mahle that reduce compression. They have been precisely matched for weight and are much stronger than their production counterparts. The production piston rods and pins also had to make way for special components that can handle the much higher forces.
Further optimised mapping of the engine electronics also contributes to the increased power output of 750 hp / 552 kW, available between 7,500 and 8,000 rpm. The engine delivers its peak torque of 800 Nm at 5,000 rpm. With sprint times of less than 4.5 seconds from rest to 100 km/h, 9.7 seconds to 200 km/h and 26 seconds to 300 km/h the two-ton sedan is a record setter!
G-Power engine technology is available for all current M5 and M6 models. The G-Power SK III twin-compressor engine conversion with 730 hp / 537 kW starts at 56,000 Euros. Another option to celebrate the anniversary is a twin-compressor kit that boosts power output of the 5-litre V10 from standard 507 hp / 373 kW to 600 hp / 467 kW and increases peak torque from 520 to 600 Nm. It is available starting at 15,441 Euros.
In addition to the most powerful BMW engine ever to power a street-legal BMW, favourable aerodynamic properties were of elementary importance. The Hurricane RS was equipped with a G-Power "Highline" body kit. In addition to producing the desired downforce it is also designed to supply much more cooling air. It consists of front and rear aprons, rocker panels and a rear spoiler lip. The stealth-look of the Hurricane RS was chosen to do justice to its extraordinary high performance: The experts from folioCar covered the entire car with a carbon-fiber-matte Foliatec car body design film.
Two tons and a top speed of 367.4 km/h naturally place extreme demands on the tires, which were mounted on G-Power light-alloy wheels. Technology partner Michelin provided high-performance Pilot Sport PS2 tires in sizes 255/35 ZR 19 in front and 305/30 ZR 19 on the rear axle. These tires were the only ones capable of handling the extreme stress. In everyday driving the G-Power Hurricane runs on 21-inch Silverstone Diamond wheels with size 255/30 ZR 21 and 295/25 ZR 21 tires.
More contributions to the Hurricane RS's high-speed talents come from a G-Power high-performance brake system and the continuously height-adjustable G-Power coil-over RS suspension. It has nine selectable settings each for bound and rebound.
The standout cockpit of the record car features a speedometer with 400-km/h scale, clear-coated carbon-fiber panels for dash, centre console and doors, as well as an ergonomically shaped G-Power sport steering wheel with especially pleasant perforated Kjerba Nappa leather.
The G-Power Hurricane RS can be ordered as a complete car starting at 300,000 Euros. Any current M5 model - sedan or wagon - can also be equipped with the individual G-Power components.
