The G Power Typhoon is a 740bhp BMW X5M

G Power has been lavishing obscene power and dubious names onto already rather-fast BMWs for 30 years. But even so, the specs of their creations can still take some swallowing. This is new G Power Typhoon, which in a previous life was a BMW X5 M developing 567bhp. Not any more, it isn’t.

Thanks to larger twin turbochargers, a titanium exhaust and a remap for the 4.4-litre V8, G Power now claims a power output of some 740bhp beneath its trademark orange engine shroud. Torque has risen from the standard car’s 553lb ft to 723lb ft, and arrives at the road via new 23in rims wearing 315mm tyres. Which ought to make it quick enough to stop passers by grimacing at the bodykit G Power’s applied.

There’s no quoted 0-62mph time, though it’s sure to be an improvement on the X5 M’s hardly tardy 4.2second personal-best. Top speed is now north of 186mph, and the German tuners claim a quarter-mile run of 11.5 seconds. That’s almost two seconds ahead of one of Top Gear’s current favourites in the uber-4x4 set, the Audi SQ7. 

Fast SUVs still struggle to be socially acceptable. Tuner cars even more so, and machines named after natural disasters are hardly likely to change that. But if you must have a X5 with Aventador-bating power, the search ought to end here. We hope.
