2007 Jaguar XJ-Series XJR Trim Overview

This powerful full size R-Style sedan is the fourth step in the XJ lineup.  The top two models are fitted with a supercharger, and each provide a unique set of additional features.  The XJR is priced at a very substantial increase over the entry level XJ8, but this Jaguar offers much more than just a performance-focused presentation.
For 2007, Bluetooth wireless technology is added to a long roster of standard features, and the XJR's seats are now finished with a higher grade of leather.
The XJR is differentiated from the three lower XJ models by the addition of 19-inch wheels, wider tires, larger brakes, front park control, a sport-tuned suspension, and adaptive cruise control.  The XJR also receives some of the Vanden Plas model's luxury upgrades, like the premium sound and navigation systems.  The XJR uses the shorter wheelbase body of the XJ8.
The XJR power plant has the same foundation as all other models: a 4.3 liter DOHC V-8 with an aluminum block and heads.  The XJR and Super V-8 models are set apart from the others by the induction system.  A supercharger boosts both horsepower and torque by a 100-count.  The 400 horsepower and 413 pound-feet of torque help send the XJR from 0 to 60 in five seconds flat, according to  Jaguar.
