Of the five XJ models, XJR is probably the most thrilling. The body uses a rivet-bonded aluminum alloy monocoque, which is stiffer and stronger and 40% lighter than steel. Independent, aluminum double-wishbone suspension with larger anti-roll bars, featuring R-tuned self-leveling air springs and enhanced Computer Active Technology, analyze road conditions and curtail pitch and roll. The level is lowered automatically at higher speeds so that the car will be more stable. In other words the closer to the ground the car is, the greater its stability.
