The Bentley Bentayga is the fastest SUV in the world and is also one of the most powerful. With 600 hp and a top speed of 187, the Bentayga is a monstrous SUV that can keep up with supercars. If the Bentayga's insane, then Manhart's 700 HP BMW X5 M is a proper monster. A stock X5 M's 4.4-liter twin-turbo V8 makes a whopping 567 hp and 554 lb-ft of torque. The tuning company didn't think that was enough and upped the performance to an incredible 700 hp and 665 lb-ft of torque.

Thanks to engine software modifications, a custom exhaust system and stainless steel mufflers, the X5 M is now into supercar territory with its performance. Manhart hasn't released any performance numbers for the vehicle, except for the fact that by removing the 155 mph limiter, the SUV can sprint all the way up to 196 mph. In regards the SUV's aggressive look, the tuning company fitted the vehicle with 22-inch BBS wheels, H&R lowering springs, as well as a matte gray wrap. None of these upgrades are cheap with the H&R springs costing $1,200, then there's $3,700 for the wrap, $4,500 for the BBS wheels and rubber, while the performance parts cost $8,000 plus installation.
