This big, black and bad BMW X5 is from German tuner G-Power, which calls it the Typhoon Black Pearl. Its name, which contains a devastating weather condition, denotes that this mean machine is very powerful and very fast. Does it live up to the name?

G-Power’s SK III RS supercharger system is bolted onto the standard X5’s 4.8-litre V8, increasing power from 350 bhp to 625 bhp at 6,100 rpm. Torque meanwhile, swells to 700 Nm at 5,300 rpm, an increase of 225 Nm. G-Power says that the Typhoon “reacts to any impact to the gas pedal aggressively and without any delay”. G-Power assures reliability too; the Typhoon uses a supercharger from ASA, which also supplies its wares to Alpina. The boost pressure is 1.0 bar. With that, acceleration from 0 to 100 km/h takes only 4.5 seconds, while top speed is “more than 300 km/h”.

Besides forced induction, G-Power has tweaked BMW’s V8, starting with a new set of forged pistons, weight-optimised connecting rods and a “precisely manufactured” crankshaft. Fuel injectors with a larger capacity, a new ignition map and an additional cooling system for engine oil and water are the other changes.

The body makeover is of OEM-quality, says its maker. The Typhoon wears 23-inch Silverstone aluminium wheels wrapped with 315/25 ZR high performance tyres by Michelin. More pictures after the jump.
