G-Power already broke the record for the world’s fastest sedan with their G-Power M5 Hurricane RS but now they raise the bar a bit and improve their record with the Hurricane RR. They reached a top speed of 367.4 km/h (228mph)

The G-Power BMW M5 Hurricane RR has a power output of 800 hp / 588 kW and delivers a peak torque of 800 Nm at 5000rpm.

To achieve these extreme numbers, the twin supercharger system of the V10 has been redesigned. The two superchargers have been replaced by the larger ASA T1-316 units and are belt-driven. A theoretical power output of over 900 hp is possible so perhaps we will see them improve their record even further with this engine in the near future.

The G-Power kit is available for all current M5 and M6 models and starts at 56.000 euros excl. VAT.

Right before BMW announces the new BMW M5, Nowack introduces a small upgrade for the current M5.

We’ve already seen Nowack do the Cooper S, X5m and X6m and now they took care of the E60 M5.

They already did the M5 and called it the N635S with 635bhp but to honor the current M5 and give it a proper goodbye, they introduced this special limited edition: ‘The N635s 5.8 Nowack Edition”

The modified 5.8 liter V10 engine now throws out 718bhp at 9000rpm.
