IF you're into raw power, but don't like to boast about it, Jaguar has the perfect car for you.

It's a Touring version of the outrageous XE SV Project 8 which claimed a Nurburgring lap record for a four door saloon last year.

Developed by Jaguar's Special Vehicle Operations division, it's probably the ultimate Q car - a four door saloon with supercar statistics.

The boot-mounted adjustable carbon fibre wing of the original car has gone and been replaced by a discreet new rear spoiler, delivering a covert design that belies the 592bhp vehicle's race track-honed performance capabilities.

It's a significant aerodynamic revision which, because of the reduced downforce, cuts the top speed of the Touring version to 186mph compared with the original's 200mph. Even so, the five-litre, supercharged V8 engine delivers extreme performance, with the 0-60mph sprint ticked off in a supercar-standard 3.3sec.

Only 15 Touring specification versions of the Project 8 will be hand-built for worldwide sale alongside existing 200mph Project 8 derivatives, some of which are still available priced from £149,995. The Touring version comes only as a four seater while the original Project 8 model can also be specified as a two-seater with the Track Pack option.

Says Jaguar Special Vehicle Operations engineering director, Jamal Hameedi: "Touring specification extends the appeal of Project 8 to performance car enthusiasts and collectors who prefer a more discreet appearance, without compromising its driver-focused on-road dynamics."
