Jaguar has been touting the aluminum-intensive construction of the XJ sedan since the previous-generation model was introduced back in 2003. According to the automaker, the use of aluminum in lieu of steel can lead to an impressive 40 percent reduction in weight. That's bound to have positive effects on driving dynamics, performance and efficiency.
With its latest redesign, Jaguar claims to have improved its aluminum architecture even further, so it's not surprising that the company plans to extend the technology to the rest of its line. According to Ratan Tata, chairman of the company that now owns Jaguar Land Rover, "JLR is planning to have all its future cars constructed with light weight aluminum bodies resulting in considerable savings in weight, and reduction in CO2 emissions."
To go along with their new diets, Jaguar and Land Rover are known to be experimenting with hybrid powertrains. A kinetic energy recovery system may be in the cards for the XJ line in 2011 while Land Rover has been working on an Electric Rear Axle Drive that could debut in the upcoming LRX compact Range Rover.
