This is the ultimate BMW vs Mercedes showdown. We wanted to find out which is quickest - the new 2018 F90 BMW M5, with its 600hp 4.4-litre twin turbo V8, or the Mercedes-AMG E63 S and its 612hp 4.0-litre twin turbo V8. Both have loads of space, both are super luxurious, both cost almost £90,000 and both have clever all-wheel-drive systems which can be switched into rear-wheel-drive only mode. But we didn't use that for this carwow challenge. This video is all about acceleration and stopping performance. Mat Watson will be driving the new BMW M5 - and he likes to win at these things. So which will take the glory - the BMW M5 or the the Mercedes E63 S? Watch the drag race to find out.
