Jaguar’s SVO-developed XE SV Project 8 is now the world’s fastest four-door car, following a production-intent prototype’s record lap of the Nürburgring Nordschleife. The incredible time of 7min 21.23sec is nearly 11 seconds quicker than the previous fastest sedan around the legendary 12.9-mile German circuit and puts the 600PS Project 8 ahead of some of the world’s fastest two-door coupés and supercars.
