Following up on the G-Power M5 Hurricane RS, with its tuned 750 hp engine powering it to ‘the world’s fastest sedan’ record of 367.4 kph earlier this year, G-Power has created a new version of their modified BMW M5 called the Hurricane RR, now capable of 372.1 kph.
But it’s not just the two-ton vehicle’s top speed that’s impressive – it can accelerate from 0 to 100 km/h in 4.35 seconds, up to 200 km/h in 9.5 seconds and up to 300 km/h in 25.8 seconds.
To achieve such impressive performance, the twin-supercharger system of the high-revving V10 has been redesigned. The two “ASA T1-313″ superchargers named have been replaced by larger “ASA T1-316″ units.
An optimised mapping of the engine electronics contributes to the increased power output of 800 hp, available between 7,500 and 8,000 rpm. The engine delivers its peak of torque of 800 Nm at 5,000 rpm.
Moreover, G-Power says the increased air volume being transported by these modified superchargers is able to generate a theoretical power output of more than 900 hp.
The inner workings of the 10-cylinder, four-valve engine are optimized by light, precisely balanced MAHLE high-performance forged pistons with lower compression and increased mechanical strength.
The company says it also replaced the standard connecting rods and piston pins because they weren’t up to the considerably increased forces found in the engine.
In addition to the most powerful BMW engine ever being fitted to a street-legal M5, the Hurricane RR is also fitted out with the G-Power “Highline” body kit, which provides increased downforce as well as significantly more air flow to cool the engine. The body kit consists of front and rear skirts and spoilers, doors render and the rear spoiler.
The Hurricane RR also features a G-Power high-performance brake system and height-adjustable G-Power RS coilover suspension that is adjustable for both compression and rebound in nine settings.
To do the actual top-speed test, the M5 Hurricane RR had its standard 20-inch forged wheels to 19-inch ones fitted with high-performance Michelin Pilot Sport tyres (255/35 at the front axle and 305/30 at the rear axle) certified for speeds of more than 370 kph.
The G-Power technology is available for all current M5 and M6 models. The basic G-Power SK III bi-supercharger engine conversion with 750 hp starts at 56,000 Euros.
Inside the car features a tachometer reading up to 400 km/h, clear-coated carbon-fiber panels for the dashboard, center console and door panels, and an ergonomically shaped G-Power sports steering wheel with specially perforated Kjerba Nappa leather.
The G-Power Hurricane RR can only be ordered as a complete car with only five cars to be made available worldwide – hence a 300,000 Euro price tag (approx. US$385,250).
