BMW X5 M vs Mercedes-AMG GLE 63 drag race

Why would we put two giant off-roaders head-to-head on the drag strip? Because they are unbelievably fast, that's why.

BMW and Mercedes-AMG make some pretty bold claims for their latest breed of super SUVs, but we couldn't quite believe the numbers that flashed up on the VBox.

Watch the video to see the exact figures, but suffice to say you should think very carefully about taking on these two brutes at a set of traffic lights, no matter what you're driving.

On paper, they are fairly well matched, with the new GLE 63 packing 430kW/760Nm from its 5.5-litre twin-turbo V8 playing the 420kW/750Nm of the X5 M's 4.4-litre twin-turbo V8.

However, as fast as these two are, consider this: the forthcoming Bugatti Chiron will weight considerably less than either of these monsters, yet will pack as much power as both of them combined. Maybe one day we can line that up on the strip.

Until then, enjoy.
