Jaguar is expanding the XF range with the addition of the high-performance XFR.
The lower-premium car is powered by a supercharged 510hp version of Jaguars new 5.0-liter direct-injection V-8. That power is routed through a six-speed automatic transmission. Jaguar says the XFR goes on sale this spring in both the US and Europe.
On the road, the XFR goes from 0 to 100kph in 4.7 seconds, Jaguar says, and top speed is electronically limited to 250kph.
The car can go a lot faster.
In November, a slightly modified XFR with the 5.0-liter engine became the fastest Jaguar ever. The car was pushed to 364kph during a test run at the Bonneville Salt Flats in the US state of Utah.
The previous record was 349kph, which was set in 1992 by an XJ220.
To make the record-setting XFR even faster, Jaguar engineers made modifications to improve its aerodynamics at high speeds.
We lowered the ride height and put a big spoiler on the back to keep the car on the ground, said Jaguar Programs Director Mick Mohan. We removed the catalysts, put in racing fuel and made a slight change to the supercharger pulley -- but all the internals were absolutely standard.
Launched alongside the XFR at the show were coupe and convertible versions of the XK upper-premium model. Both cars are powered by the same 510hp engine that is in the XFR.
