Back with a brand-new generation for 2019, the BMW X5 is bigger, more luxurious and more technologically advanced than ever. While the list of options is almost never-ending, there are just two engines available: a turbo 3.0-litre six cylinder and a twin-turbo, 4.4-litre V8 producing 456 horsepower. The diesel version won't be back for 2019, and the plug-in hybrid and X5 M have also been put on pause, but they'll return in a year or two.
