Jaguar Land Rover’s Special Vehicle Operations (SVO) has announced what it calls the most powerful, agile and extreme performance road legal Jaguar ever – the Jaguar XE SV Project 8, which will “offer supercar performance and dynamics in a sedan.”

The XE SV Project 8 will become the second Collectors’ Edition vehicle from SVO, following the Jaguar F-Type Project 7 in 2014. No more than 300 cars, all hand-assembled at SVO’s Technical Centre in Coventry, will be created for sale worldwide.

Under this compact beast’s hood is the most highly tuned version of Jaguar Land Rover’s 5.0 litre supercharged V8 engine, pushing out 600 PS. Full specifications will be revealed soon ahead of its world dynamic debut at Goodwood Festival of Speed in in the UK on June 30. It has been developed at the Nurburgring, as these pics and video of the prototype show.

For now, Autocar says that the mega saloon is all-wheel drive and uses a modified version of the eight-speed ZF automatic gearbox. Jaguar’s above claims would mean that the mad XE will be faster than the F-Type SVR, so expect 0-100 km/h below 3.5 seconds and top speed in excess of 320 km/h.

“The time is right for SVO to produce the most extreme performance road car in the history of Jaguar. The SVO team is possessed by the spirit of performance and committed to creating the most thrilling driving experience imaginable,” said John Edwards, MD of JLR’s performance arm.

“Our clients worldwide were thrilled by the F-Type Project 7. The new XE SV Project 8 takes aerodynamics and performance engineering to another level – it is conceived for enthusiasts and the most discerning collectors. The price for such an extreme performance sports car available in strictly limited numbers will reflect that,” he added.
