Jaguar North America and Rocketsports Racing Unveiled the Ultimate XKR
at the 2004 Chicago Auto Show
(February 5, 2004)
most powerful road-going Jaguar convertible ever -- the 550 horsepower
XK-RS concept car -- was unleashed at the 2004 Chicago Auto Show.
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.
at Rocketsports' 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 liters.
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.
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
make the car more involving for the sports car enthusiast, the standard
six-speed ZF automatic transmission was replaced with a six-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.
also used the team's considerable expertise in high-speed aerodynamics
with its Jaguar XKR Trans-Am racecars, modifying the production XKR's
body to ensure ground-hugging stability at very high speeds.
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 year's James Bond adventure, 'Die Another Day'.
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
production XKR'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
rotors (13-inch front/12-inch rear) were added.
the XK-RS features body-hugging Johnson Controls "Leap" seats
clad in black leather with medium grey inserts.
complete the bold appearance, the concept is painted in rich black
lacquer. Along each side, Pearl Black Jaguar 'leaper' graphics echo
those used on Rocketsports Racing's XKR racecars.
XK-RS concept is one more example of our strong relationship with Paul
Gentilozzi and Rocketsports Racing," said George Ayres, vice
president of Marketing for Jaguar North America. "The XK-RS uses
Rocketsports' considerable race car expertise to create this dramatic,
one-off concept car."
The XK-RS is Rocketsports' second Jaguar project car. In 2002, Rocketsports created the purposeful 'Racing Concept' version of Jaguar's all-wheel drive X-TYPE. The dramatic-looking concept racecar was developed to test the potential of Jaguar's X-TYPE as a project car for the enthusiast market.
