An unintentional yet fitting tribute to the GMC Typhoon of legends told, the G-Power BMW X5 Typhoon RS has been maniacally tuned to take the luxury SUV places no whitebread grocery getter should go. As a matter of fact, so complete was G-Power’s overhaul it’s nearly impossible to assimilate the supercharged behemoth above with the sedate SUVs that flood the school parking lot at every PTA meeting. Nothing save for the chassis was left untouched, which made for a pretty wordy press release that was both exhausting and mildly uncomfortable to read. For a bunch of dudes who are big into wrenching, they were laying down some pretty flowery prose and it took about three scans before we were able to sift through to the important details.
First and foremost we begin with the engine, which is still the same 4.8L V8 found beneath the E70, but with nearly double the horsepower. Outfitted with the G-POWER SK III RS supercharger system, output was boosted from a respectable 350-hp to a staggering 625-hp at 6100 rpm and 516 lb-ft of torque at 5300 rpm. 0-62 mph is achieved in 4.5 seconds and 0-124mph in 16.0 seconds while top speed is electronically limited to 177 mph.
Outside, G-Power brought out every aerodynamic gun in their arsenal. The stock bumpers were ditched in favor of aggressive front and rear skirts, the former which perform the dual function of allowing for larger air inlets and reducing the front axle’s lifting forces. Just as notable in function, the rear skirt provides an outlet for the stainless steel sport dualie exhaust and, when combined with the rear spoiler, also works to reduce drag. Shoes come courtesy of Michelin and measure 315/25 ZR 23 while wing extensions were added to the front and back axle to accommodate the larger-than-stock forged aluminum wheels (11Jx23 front, 12Jx23 rear).
So how much will it hurt your wallet? €12,185 ($17,974), which doesn’t include the cost of the donor car. Worth it? Hell yes.
