G-Power GXM Bi-Turbo Is A BMW XM With Even Less Subtlety
Not only does the BMW XM send a confusing message by being both an SUV and the first standalone M car since BMW's only production supercar to date, but the awkward bodywork, separated headlight clusters, and bulging taillights leave the aftermarket with very few options short of a rebody, and that's not a sound business model when the XM is being outsold by even the Z4. G-Power's solution is to lean into the overt nature of the design by sticking even more angular plastic and carbon fiber elements to the jagged SUV. But instead of designing its own kit from scratch, G-Power has borrowed the entire aesthetic package from Mansory. The only exceptions are the 23-inch Hurricane RR forged wheels, with G-Power's real influence felt beneath the hood.
G-Power Extracts More From The Twin-Turbo V8

As a reminder, the XM, now only available in Label trim, features a 4.4-liter V8 hybrid powertrain delivering a maximum of 738 horsepower and 738 lb-ft - good enough for 0-60 mph in 3.6 seconds and a top speed of 155 mph. The GXM package turns that up to 950 metric horsepower (937 bhp) and a dizzying 1,032 lb-ft of torque, with the speed limiter also rising to somewhere north of 186 mph. With such a powerful base to begin with, the only changes the tuner needed to make were to fit a pair of sport downpipes and write a new tune for the ECU. G-Power says that adding a Deeptone exhaust system will allow the GXM to exceed 1,000 hp, and it intends to show that vehicle soon. Hopefully, that one will have a less lurid paint job.
Numerous Cosmetic Options On Offer

With a tiny market for the XM and an even tinier one for tuning it, G-Power was prudent to raid Mansory's catalog. The options available to the XM (in twill or forged carbon) include hood, mirror caps, front apron (with or without add-ons framing the headlights and side intakes), wheel arch and door extensions, rocker panel lip, rear diffuser (again without or without flaps to match the front), roof spoiler, and decklid spoiler, and both G-Power and Mansory offer full interior makeovers. Pricing is a mystery, but when the result is something intended to make a Lamborghini Urus look tame, this thousand-pony SUV won't be cheap in any guise.
