Following a preview earlier this month, Jaguar has officially unveiled the 2014 XJR.

Set to debut at the New York Auto Show this week, the XJR has stylish exterior with a new front bumper, aerodynamic side skirts and a trunk-mounted spoiler. The model is also equipped with a ventilated hood, a four-tailpipe exhaust system and 20-inch forged alloy wheels with bespoke Pirelli tires.

Interior changes are limited but the model comes nicely equipped with two-tone leather seats that have contrast stitching and embossed "R" badging. There's also a 12-speaker Meridian audio system and carbon fiber or piano black trim.

As expected, the XJR is powered by a supercharged 5.0-liter V8 engine that develops 550 HP (405 kW) and 680 Nm (502 lb-ft) of torque. It is connected to an eight-speed automatic transmission which enables the sedan to accelerate from 0-60 mph in 4.4 seconds (0-100km/h in 4.6 seconds) and hit an electronically-limited top speed of 174 mph (280 km/h). In terms of efficiency, owners can expect to average 24.4 mpg UK (11.6 L/100km / 18 mpg US) with CO2 emissions of 270 g/km.

On the handling front, engineers installed a retuned suspension, an electronic rear differential and a recalibrated Dynamic Stability Control system. The model has also been outfitted with a new steering system that promises to deliver improved "feel, response and feedback under all driving conditions."
