2007 Jaguar XKR



Just a few months after Jaguar's redesigned 2007 XK hit dealerships, the automaker announced the addition of a high-performance XKR. Much like the previous-generation XK8/XKR, the new XKR offers a supercharged V-8 engine. Here it achieves 420 horsepower, 30 more than its predecessor. Like the XK, the XKR is available in two-door coupe or convertible form.

Pricing has been set at about $86,000 for the coupe and $92,000 for the convertible, which is about $12,000 more than the XK. The XKR hits showrooms in January 2007.

Exterior
Free of the elaborate appendages many automakers slap on their performance cars, the XKR looks much like its XK sibling. Changes include a mesh insert in the grille and air dam, twin louvers on the hood and smaller fog lamps with grille inserts below. In back, four exhaust pipes — instead of the two found on the regular XK — sit below a revised lower bumper.

Nineteen-inch wheels replace the XK's 18-inchers, and 20-inch rims are optional. Black brake calipers clutch enormous 14-inch front discs that are nearly 10 percent larger than the XK's. Behind the wheels, Jaguar's Computer Active Technology Suspension has been calibrated for higher-performance handling, and springs and shock absorbers have been sport-tuned.

Jaguar says the XKR coupe's body is 154 pounds lighter than the previous-generation XKR, and the convertible is 220 pounds lighter.

Interior
The XKR's interior benefits from aluminum dashboard trim and sport seats with aggressive side bolsters. Various leathers and trim colors are available. Drivers are reminded of the beast behind the pedal by R logos on the instrument gauges, gearshift knob and steering wheel. Available luxury accoutrements include a navigation system and heated 16-way power front seats.

Under the Hood
A supercharged 4.2-liter V-8 develops 420 hp at 6,250 rpm and 384 pounds-feet of torque at 4,000 rpm — both substantial increases over the XK's 300 hp and 320 pounds-feet of torque. A six-speed automatic transmission includes a manual mode via steering wheel paddle shifters. Jaguar says its Active Exhaust System produces an accelerative roar when the V-8 is pushed hard, but quiets things down for highway cruising.

Jaguar says the XKR coupe accelerates from a standstill to 60 mph in 4.9 seconds, and the convertible does it in 5.0 seconds. Both figures are a full second ahead of the XK coupe and convertible.

Safety
All-disc antilock brakes, front and side airbags and an electronic stability system are standard. The XKR's front brakes are larger in diameter and thickness than the XK's.
