Jaguar are putting the final touches to the all new Jaguar XE saloon ahead of the public reveal at the Paris Motorshow and the company is claiming it will be the most fuel efficient vehicle in brand history. The XE is an Audi A4, BMW 3 Series and Mercedes C Class headache and Jaguar’s biggest selling point will be the extensive use of aluminium which will account for 75 percent of the cars body/chassis. Fuel consumption figures being touted by Jaguar range from 75 mpg  (62 U.S. mpg; 3.8l/100km) and CO2 emissions of less than 100g/km. Jaguar are making bold statements about the fuel efficiency and certainly don’t want to be seen doing a ‘Hyundai’, they blatantly lied about thier car’s fuel efficiency. But there is a growing trend for the use of aluminium in the auto industry to reduce emissions, weight and improve fuel economy. The XE’s ride and handling will be aided by integral link rear suspension, a new grade of high strength aluminum has been developed specifically for the XE and it will be the first Jaguar to make use of a new rear-wheel drive all aluminium chassis. The aluminum “gives us a body structure with unrivaled low weight: it’s light but also immensely strong with extremely high levels of torsional stiffness,” Mark White, Jaguar’s chief technical specialist, body complete, said in a statement. “We’ve made sure our aluminum-intensive body structure exceeds all global safety standards without compromising on vehicle design or refinement.” The Jaguar XE will use a new generation of 4-cylinder diesel engines.
