The X-Type is a compact executive car manufactured from 2001-2009.
The X-Type, was Jaguar's first compact 4-door saloon since the Jaguar Mark 1 of 1955. The X-Type was one of the last to be styled under the supervision of Geoff Lawson, with the principal designer credited as Wayne Burgess.
The X-Type was lightly based on a modified version of the Ford CD132 platform shared with the 2000 Ford Mondeo. However the Jaguar X-Type only shares about 15 to 20% of the Ford Mondeo design and has unique features which lets it stand on its own as original design platform. Nearly all cars made today use cross platform design to lower cost of production and to provide replacement parts across vehicle lines. Distinguishing it from its rivals and its Ford origins, the X-Type was initially offered as all-wheel drive only and mated to a 2.5 litre and 3.0 litre AJ-V6 petrol engine. The AJ-V6 petrol engine design is unique to the Jaguar X-Type; one notable addition is the use of variable valve timing. The Jaguar X-type AJ-V6 petrol engine is also set apart by the use SFI fuel injection, 4 valves per cylinder and features fracture-split forged powder metal connecting rods plus a one-piece cast camshaft and has direct-acting mechanical bucket (DAMB) tappets. In 2003, the X-Type was offered in front-wheel drive with the introduction of Jaguar’s first four-cylinder diesel engines and with the smaller 2.0 litre petrol V6.
