M5 not powerful enough for you? German tuner G-Power has announced a frankly ludicrous supercharged version of the fast BMW. The Hurricane is an apt name for the blown Beamer – it produces a scarcely credible 720bhp and has been certified at 211mph.

G-Power uses two belt-driven compressors for each bank of the 5.0-litre V10; using two smaller superchargers keeps the weight down and makes them more efficient – each uses 0.5 bar of boost pressure. And it’s not just a bolt-on-and-leave-the-rest-alone job. The German tuners have also fitted new forged pistons, a new intercooler, bigger oil cooler and revised engine mapping.

Peak power lands, with considerable force, at 7500rpm while maximum torque of 516lb ft arrives at a heady 7200rpm. Sounds worryingly peaky, but G-Power claims the Hurricane out-pulls the M5’s maximum thrust by 3800rpm.

End result? The two-tonne saloon scampers to 62mph in 4.2 seconds (half a second faster than the regular M5) and by 124mph the gap has stretched to five seconds. G-Power has a barrage of performance claims, and says the Hurrican will keep on accelerating all the way to 211mph.

The sort of people who’ll buy the maxed-out M5 will love the styling accoutrements. There’s a new front apron (crafted from carbonfibre upon request), rear diffuser and spoilers to channel air to the correct places, while 21-inch wheels wear chunky 30-section Dunlop high-speed rubber and house bigger, six-piston brakes.

All this excess carries a price, of course. The finished item costs a faintly ridiculous £178,000, or you can convert an existing car for £66,000. Which is the same as the M5 costs in the first place…

We’d dispute G-Power’s claim that the Hurricane is the most powerful street-legal BMW on sale. Californian tuner Currency Motors produces a twin-turbocharged M5 that develops 800bhp. Just goes to show you can have too much of a good thing.
