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.
