Jaguar XJ-Series

Overview

The XJ sedans play in the same upscale neighborhood with entries from BMW and Mercedes-Benz. The base engine is a 4.2-liter naturally aspirated V-8 that makes 300 hp and 310 lb.-ft. of torque. This engine is found in the XJ8, XJ8 L, and Vanden Plas models and enables the XJ to reach 60 mph in just over 6 seconds, according to Jaguar. The XJR (the �R� stands for Jaguar�s racing-series model) gets the supercharged 4.2-liter V-8 that adds an extra 100 hp and more than 100 more lb.-ft. of torque to the Jaguar sedan�s performance, trimming off a full second of the 0-60 mph time. All XJ engines are mated to a ZF 6-speed automatic transmission.

The fifth model is the Super V8, which adds the following to the long-wheelbase XJ8 L model: the supercharged engine, 19-inch alloy wheels, �R� performance braking, radar-based Adaptive Cruise Control, a navigation system, a 320-watt Alpine audio sound system, four-zone climate control, and a power-adjustable rear bench seat. And for good measure, the Super V8 also features lambs-wool rugs and a heated, wood steering wheel.

While the XJ�s engine technology may be advanced, so is the all-aluminum body, which helps reduce weight (and therefore braking effort) yet is strong enough for occupant protection in the event of an impact. The Jaguar features powerful brakes with larger rotors, stiffer calipers, and state-of-the-art technology like Brake Assist, which enhances brake pedal effort in emergency braking situations to help the driver stop the vehicle before the impact occurs.
