The XJ Diesel is also the quietest vehicle in its class for exterior noise, with the noise level measured by the Vehicle Cerification Agency being seven decibels (A) lower than the EU legal limit for diesel vehicles. In order to achieve this, the exterior noise package has been significantly enhanced.

The XJ 2.7 litre twin-turbo Diesel is best-in-class for isolation from engine idle vibration. This is achieved with active engine mounts, which are introduced on all 2006MY XJ Diesels and are an industry first. The engine mounts were designed and developed in conjunction with Avon Automotive. Diesel engines generate much greater levels of vibration than their petrol equivalents, which is why the mounts are being fitted to the XJ Diesel variants. Active mounts use an electronic control system and a powered mechanism to cancel an additional 90 per cent of this engine vibration at idle.

A system that can cancel out in excess of 90 per cent of engine idle vibration into the car has a huge impact on the vibration levels experienced by the vehicle occupants. This technology, in conjunction with the other noise, vibration and harshness (NVH) improvements, ensures that Jaguar delivers class-leading levels of refinement for the XJ's first ever diesel engine.

Significantly Lower Cost Of OwnershipThan Rivals

During the development of the XJ 2.7 twin-turbo Diesel, Jaguar’s engineering team worked closely with our Customer Service Organisation to deliver excellent cost of ownership figures. The diesel-powered XJ benefits from an increased standard mileage service interval over the petrol models, resulting in an approximate saving of 7 per cent in routine maintenance costs over five years.

Against diesel competition - in the shape of the Mercedes S320 CDi - the cost of routine maintenance is forecast to be an impressive 27 per cent less for the XJ 2.7 TDVi. Similarly, wear and tear index costs compared with the Audi A8 3.0 Tdi and Mercedes S320 CDi are forecast to be 25 and 28 per cent lower respectively.

The XJ 2.7 TDVi has a predicted insurance group of 16E, giving it joint best-in-class rating alongside the Mercedes S320 CDi and a whole group improvement over the BMW and Audi equivalent models. Factor into the equation a combined cycle fuel economy of 35mpg from the 207PS 2.7 twin-turbo diesel [CO 2 214g/km = 29% Benefit In Kind or BIK tax category] and the XJ 2.7 TDVi has the lowest company car tax bill of any car in the luxury sector.

“Our new XJ diesel model is fast, refined and economical,” says Bibiana Boerio, managing director, Jaguar Cars. “And our customers will relish the fact that this is a luxury saloon that makes no compromises. We don’t ask them to trade performance for refinement or economy for power. This is a true Jaguar XJ, just like every other model in the range.”
