G-Power has taken their BMW M5 and has officially made it the world’s fastest sedan clocking in at 372 km/h or 231 mph. Dubbed the Hurricane RR, G-Power has beaten its own previous record of 367.4 km/h or 228 mph. The M5 is able to achieve this top speed through its twin-supercharged V10 engine that puts down 800-hp and 590 ft-lbs of torque.
G-Power informs that the ASA T1-316 superchargers used in the setup could theoretically output over 900-hp. The V10 has obviously been rebuilt, using Mahle pistons and custom rods. The ECU was remapped and tuned to ensure its highest horsepower output is in the M5’s 7500-8000 rpm range.
The record run was achieved on 19-inch G-Power forged wheels wrapped with Michelin Pilot Spot tires. The Hurricane RR as you see it in all its record-setting glory can be ordered from G-Power for a measly $320,000 . But if you’ve already got an M5 or M6 sitting around, G-Power’s twin supercharger setup starts at around $71,415.

Official press release after the break.
Now that BMW is truly embracing the technology behind their twin turbo applications, it’s no surprise that there will be an entirely new generation of M-powered vehicles that will no longer sport large displacement, naturally aspirated V8 and V10 engines. Nowack Motors, who we checked out before with their Mini Coopers, is known for tuning BMW M engines, and their newest product is impressive.
Named the N635S 5.8 Hans Nowack Edition, the 5.0L V10 pushes out 718-hp over the factory 507-hp and revs up to 9000 rpm. This engine conversion is available for all the M5s and M6s sporting the 5.0L V10, and Nowack offers a 12 month warranty with no mileage constraint for those opting to have the work done. So while BMW is pushing ahead with their twin turbo setups and abandoning the joy of torque-heavy V10s, Nowack motors continues to embrace and give current owners a new option to compete with the new technology.
There is unfortunately not a ton of details on what goes on with the conversion other than a remapped ECU and a pair of intake air collectors that are match painted to the car. But we’re going to guess that there’s tons of bottom end work and head work. Then again, it can’t be that difficult to find a whole lot of horsepower once you crack open a V10 can it?
The official press release available after the break.
