Traditionally, the bodies of Jaguar cars have been made of steel. In 2002, Jaguar introduced the aluminum-bodied XJ series, weighing 295 kg, instead of a steel body weighing 475 kg. The decision to use aluminum saves about 1,500 litres of gasoline for each vehicle, if a total life cycle driving distance of 200,000 km is assumed.
A life cycle assessment which takes into account production, use and recycling shows that, under such standard assumptions, more than four tonnes of greenhouse gas emissions can be saved per car, i.e. more than 14 kg of GHGs for each kg of aluminum in the car body. Assuming a production run of 160,000 cars, the decision to use aluminum will result in total greenhouse gas savings of more than 600,000 tonnes.
The intensive use of aluminum in cars supports high recycling rates, expected to be close to 100%, when the vehicles reach the end of their useful life.
