Jaguar XK-RS Concept

Monster XK-R shows what could be done. Trouble is it's just a concept...


The most powerful road-going Jaguar convertible ever โ€“ the 550 horsepower XK-RS concept car โ€“ was unleashed at the 2004 Chicago Auto Show today.

The car has been developed by Michigan-based Rocketsports Racing in cooperation with Jaguar North America.

"At Rocketsports, weโ€™re very familiar with Jaguarโ€™s XKR sports car, having won the Trans-Am Manufacturersโ€™ Championship two times with this beautiful, fast car ," said Rocketsports Racing owner, Paul Gentilozzi.

"We think the XKR makes a great foundation for high-performance tuning. The XK-RS concept is just one dramatic interpretation of the many directions in which the car can be taken ," he added.

Engineers at Rocketsportsโ€™ Lansing, Michigan workshop took the already-potent Jaguar AJ-V8 Trans-Am race engine and increased its displacement by stroking it out from 4.5 liters to 5.0 litres.

To ensure drivability, the engineers reinstalled an Eaton supercharger to deliver an estimated 550 bhp and 500 lb. ft. of torque, giving the car the power to accelerate from standstill to 60 mph in under four seconds, and take it to a top speed of 200 mph.

"Many of the lessons we learned in developing the 650 bhp normally aspirated Jaguar AJ-V8 race engine for the R-Performance XKR Trans-Am race car were incorporated in the engine for the XK-RS ," explained Gentilozzi.

To make the car more involving for the sports car enthusiast, the standard six-speed ZF automatic transmission was replaced with a five-speed manual transaxle. Re-positioning the driveline weight to the rear of the car also results in a perfect 50:50 weight balance for improved handling.

Rocketsports also used the teamโ€™s expertise in high-speed aerodynamics with its Jaguar XKR Trans-Am race cars, modifying the production XKRโ€™s body to ensure ground-hugging stability at very high speeds.

Special underbody air tunnels running the length of the car were created, along with deeper front and rear spoilers, wider wheel arches and aero-style sill sections similar to those featured on the specially-developed XKR that starred in last yearโ€™s James Bond adventure, โ€˜Die Another Dayโ€™ .

When tested in the wind tunnel, the changes are expected to result in a 100 percent increase in aerodynamic downforce at top speed compared to the standard car.

The production XKRโ€™s suspension was also modified to ensure supercar handling. The changes include the addition of coil-over high-performance Penske shocks. To give the concept the kind of stopping power that matches its anticipated grip, R -Performance Brembo calipers with drilled discs (13-inch front/12-inch rear) were added.

And no 200 mph supercar would be complete without a dramatic wheel and tyre combination. The XK-RS comes fitted with three-piece wheels - center-lock 'Machiavelli Gotti' โ€“ 20-inch x 10-inch at the front, 20-inch x 11-inch at the rear โ€“ shod with high-performance Michelin Pilot tyres.

Inside, the XK-RS features body-hugging Johnson Controls "Leap" seats clad in black leather with medium grey inserts.

To complete the bold appearance, the concept is painted in rich black lacquer. Along each side, Pearl Black Jaguar โ€˜leaperโ€™ graphics echo those used on Rocketsports Racingโ€™s XKR race cars.

George Ayres, vice president of Marketing for Jaguar North America chirped, "The XK-RS uses Rocketsportsโ€™ considerable race car expertise to create this dramatic, one-off concept car ."

I wont be holding my breath cos like all other concept Jags that look the biz, it will probably get binned before making it into production.

They will blame the high development costs involved (whilst at the same time blowing millions on an F1 also ran)

What we'll end up with is another lardy diesel estate from them.

I always thought the XK8 looked a little soft compared with the Aston Martin DB7 but that looks the nuts, defenately high on the want one list.

The two things that I like about all of these Rocketsport cars (like the X-type they did last year):

1. The wheels

2. The paint with the embedded leaper graphic

I was just going to say the same thing, very subtle, yet stunning.

I'm not sure I like the looks.... some elements of it are AWESOME, others are just a little too NASCAR and not enough Jaguar...... having said that, with perhaps just a vry minor amount of fiddling the styling could be made to work for me but overall it's retty tasty nonetheless..... about time Jaguar started building sports cars again...... the last time they did was back in '67 when the S1 E-Type died.... we want it back!

Stop whinging! Buy an old XK8 and make it yourself!

Oh, and it looks like a TVR, too!

Ugly. Ugly. Ugly.

The XK8 Convertible is one of the most beautiful cars ever IMO and this just "Max Power"s it. Yuck.

The idea of taking an XK8 Convertible, making it more powerful and improving the handling and providing a manual box option sounds damn fine.

If I didn't have my Porsche I'd have to think about an XK8 Convertible in dark blue...
