But now that record has been broken… by G-Power. This time though, it used the Hurricane RR. A development of the RS, the RR’s power is taken up to 789 bhp (588 kW / 800 PS) thanks to twin ASA T1-316 superchargers, Mahle forged pistons, redesigned connecting rods, strengthened piston pins and a remapped ECU.
With its extra 80 bhp, the Hurricane RR managed to hit 231.2 mph (372.1 km/h). The only change made to the car ahead of its record attempt was substituting the standard 20” wheels for 19” items. That was to accommodate special Michelin Sport Pilot tyres, certified for speeds over 230 mph (370 km/h).
Obviously, though, there are other benefits from having all that horsepower: G-Power reckons the Hurricane RR will accelerate from 0-62 mph (100 km/h) in 4.35 seconds, 0-124 mph (200 km/h) in 9.5 seconds and 0-186 mph (300 km/h) in 25.8 seconds.
The RR package also includes the ‘Highline’ body kit, which is designed for high speed stability while increasing air flow to the engine to aid cooling. High performance brakes are fitted and the suspension features G-Power RS coilover suspension that is adjustable for ride height, compression and rebound. Changes to the interior are confined to plenty of carbon fibre trim, a G-Power steering wheel and a replacement speedometer that reads up to 250 mph (400 km/h).
Customers can order the Hurricane RR as a complete car, with prices starting at €252,100 (about £206,100). Alternatively, individual components can be fitted to an M5 - and that includes the touring.
