Now that the all-new 2019 BMW X5 has broken cover, it's only a matter of time before the full-fat M version arrives. Unfortunately, we're going to be waiting a while, because the new 600-hp BMW X5 M isn't expected to be unveiled until next year. To ease the wait, Polish aftermarket specialist Auto-Dynamics has given the old F85 X5 M a new lease of life with an ambitious tuning job that gives the SUV supercar levels of performance. Under the hood, the X5 M's twin-turbo 4.4-liter V8 has been upgraded to deliver a substantial 670 hp and 649 lb-ft of torque, up from 567 hp and 553 lb-ft of torque in the stock X5 M. It's even more powerful than the mighty Lamborghini Urus, which produces 650 hp.

To achieve this huge power bump, Auto-Dynamics has remapped the ECU, fitted an Akrapovic titanium exhaust system, and upgraded the air filters along with other minor tweaks. With these modifications, the X5 M will hit 62 mph in just 3.5 seconds – not bad for an SUV that weighs 5,260 pounds. This makes it seven-tenths of a second quicker than the stock model off the line. No top speed has been specified, but it's probably safe to assume it surpasses the standard X5 M's electronically limited 155 mph top speed.

As well as upgrading the V8, Auto-Dynamics has replaced the X5 M's standard wheels with a larger 22-inch set and finished the exterior in satin black. Practically every part of the body has been painted in black apart from the blue calipers, giving the SUV a more sinister look. Carbon fiber accents and lowered the suspension round off the transformation.
