In 2.8 seconds you’re at 60 mph and in 10.9 you’re whisked through the quarter-mile at 129 mph. That makes the new M5 the quickest sedan we’ve ever tested, tying a Tesla Model S P90D to 60 mph but pulling ahead by 100 mph and in the quarter-mile.
The BMW M5 - here tested in near-600bhp ‘30 Jahre’ guise - is the default benchmark performance saloon. Can the Lexus GS F and its atmospheric, 471bhp V8 compete?
Chris Harris finds out.
