BMW’s biggest SUV is now available in M50i trim, which includes a twin-turbo, 4.4-litre V8 good for 523 horsepower and a 0-100 km/h sprint of 4.6 seconds. The xDrive40i and xDrive50i variants are no slouches either, with 335 hp and 456 hp, respectively. The X7 can seat six or seven passengers according the chosen interior layout, while the trim choices and available features are close to those offering in the 7 Series sedan.
