2014 Jaguar XJR

The full-size 2014 Jaguar XJ lineup gets a high-performance upgrade with two new XJR models, boasting wind-tunnel-defying aerodynamics, Nurburgring-tested handling and a whole lot of power.

Revealed at the March 2013 New York International Auto Show, the 2014 Jaguar XJR models go on sale this summer (2013).

The rear-wheel-drive 2014 XJR uses a supercharged 5.0-liter V8 that makes 550 horsepower and 502 pound-feet of torque, the same engine used by the Jaguar XKR sports car. It's mated to an 8-speed automatic transmission with wheel-mounted paddle shifters and uses an active locking electronic differential.

The 2014 XJR will be capable of accelerating from 0 to 60 mph in 4.4 seconds, according to Jaguar Land Rover. Top speed is electronically limited to 174 mph. Fuel economy is expected to be 15/23 mpg City/Highway.

By comparison, the regular Jaguar XJ sedan's base engine uses a 3.0-liter supercharged V6 good for 340 horsepower, and V8 models are available in a naturally aspirated 385-hp version, or a supercharged 470-hp model. They won't catch the XJR on the track, but they're nothing to shake a stick at.

Software in the XJR is tuned for sportier driving, with more aggressive shift points and an adaptive computer that can adjust shifting to match driving style. An adaptable suspension, dubbed Jaguar Adaptive Dynamics, uses variable dampers for a more hunkered-down ride.

Visually, the XJR is more aggressive with a new front bumper, front splitter, side skirts and a rear lip spoiler. But these aren't just for looks; they help to create additional downforce at high speeds and helps the XJR slip more easily through the air. New vents on the hoods help to cool the roaring powerplant that lies beneath. The XKR also sports quad exhaust pipes and rides on lightweight 20-inch wheels.

In the cabin, the XJR is wrapped in semi-aniline leather with carbon fiber or piano black trim. A 12-speaker, 380-watt Meridian audio system comes standard.

The 2014 Jaguar XJR is expected to go on sale in August 2013. Two body styles will be available: the standard wheelbase with a Manufacturer's Suggested Retail Price of $116,000, and a long wheelbase with an MSRP of $119,000. (MSRP does not include $895 destination charge.) Jaguar Land Rover announced the prices at the March 2013 New York International Auto Show.
