SPY PICS: Jag's 450kW F-TYPE SVR

Jaguar’s fledgling performance division, SVR, is secretly developing the fastest car in the history of the British car-maker.

Pictured here for the firts time on both the road and the Nurburgring is the range-topping Jaguar coupe expected to be called the F-TYPE SVR.

Clear from these images is that the first SVR sports car will wear a specific aero package including a huge rear wing to cope with a higher top speed than the F-TYPE -- said to be in excess of 320km/h with its limiter removed.

According to Autocar, the F-TYPE R will pack more than 450kW from its 5.0-litre supercharged V8 -- so powerful that engineers have had to give Jaguar's hard-core coupe all-wheel drive to transfer its power to the road.

Off the line, thanks to the all-wheel drive, the new SVR coupe should hit 100km/h from standstill in comfortably less than four seconds, but could even undercut 3.5 seconds like the Porsche 911 Turbo.

The SVR will also come with huge ceramic brakes, lightweight 20-inch alloys and a ix-speed automatic gearbox that benefits from tweaks for the recent Project 7 sports car.

Expected to go on sale next year, the new F-TYPE SVR is likely to be priced in line with Porsche 911 Turbo, with a starting price of about $350,000 — around $100,000 more than the F-TYPE R AWD.
