The most powerful road-going Jaguar
convertible ever – the 550 horsepower XK-RS concept car – was
unleashed at the 2004 Chicago Auto Show today.
Developed
by Michigan-based Rocketsports Racing in cooperation with Jaguar North
America, the XK-RS concept demonstrates how Jaguar’s luxury GT road
car can be transformed into a thundering 200-mph supercar.
"At
Rocketsports, we’re very familiar with Jaguar’s XKR sports car, having
won the Trans-Am Manufacturers’ Championship two times with this
beautiful, fast car," said Rocketsports Racing owner, Paul Gentilozzi.
Engineers
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.
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.
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 team’s considerable expertise in high-speed
aerodynamics with its Jaguar XKR Trans-Am race cars, modifying the
production XKR’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 year’s James Bond
adventure, ‘Die Another Day’. |
