This is the ultimate BMW vs Mercedes showdown. We wanted to find out which is quickest – the new 2018 G30 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 these guys 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.
