Just like the Jaguar wild cat, which is difficult to spot, Jaguar Cars Ltd, maker of the marquee car Jaguar, showed a first-teaser glimpse of what the new generation Jaguar 2010XJ would look like, when it released a picture of new luxury saloon ahead of the Shanghai Motor Show yesterday.

After having kept the details of the car under tight wrap for many months, Jaguar only revealed an overhead picture of the car along with a few skimpy details.

The Coventry, UK-based car manufacturer, seems to have made a major redesign of its flagship car since the all-new XJ will be the first car to have the next-generation of Jaguar's aerospace-inspired aluminium body architecture featuring a panoramic glass roof starting from the windshield onwards.

All of Jaguar's new ultra-efficient Gen III petrol and diesel engines will be available in the new XJ, including the already acclaimed V6 diesel and 510 bhp supercharged V8.

The car will be available in long and standard wheel-base including the new 3.0-litre diesel offered in the XF.

Jaguar-Land Rover chief executive David Smith said that the 2010 XJ will be absolutely stunning while Paul Cope, the group manufacturing director said that the appeal of the new car will make rivals like Mercedes and BMW look like yesterday's cold potatoes.

The all-new XJ will be officially revealed on 9 July in London and will go on sale at the end of 2009 while it will be launched in the North American market sometime in early 2010.

Despite of demand for new cars in the UK falling off the cliff, Jaguar is still spending money on new design and research on newer low fuel consumption cars since the latest engines in the Jaguar 2010 XJ is supposed to have one of the cleanest and most fuel-efficient of its kind.

The car maker has already started preparing to start production of the car at its Castle Bromwich assembly plant since the other XJ's were produced from this plant.

Last week, readers of Auto Express magazine have voted the new Jaguar XF as the UK's best car in the '2009 Driver Power survey.'

The results revealed that the XF secured the overall number one spot with drivers praising the Jaguar's combination of luxury, comfort and driving dynamics.

The XF, which was launched in March 2008, scored an impressive score of 91.18 per cent and the Skoda Superb (old), the Skoda Octavia, Land Rover Discovery and the Lexus RX were the other top four.
