The Jaguar X-Type is a compact executive car that was manufactured and marketed by Jaguar Cars from 2001 to 2009 in a single generation under the internal designation X400. Manufactured at the Halewood Assembly Facility near Liverpool, the X-Type was developed during Jaguar's tenure in the Premier Automotive Group (PAG) of Ford Motor Company and was based on a modified version of the Ford CD132 platform, shared with the contemporary Ford Mondeo. The smallest of the Jaguar model range, the X-Type was marketed in saloon and estate variants, and was the first estate manufactured in series production by the company.
The Jaguar X-Type, codenamed X400 was launched in October 2001 as Jaguar's first compact executive car since the Jaguar Mark 2 of 1959. The X-Type was one of the last to be styled under the supervision of Geoff Lawson, with Wayne Burgess as principal designer.The four-door saloon was launched in 2001 and in 2004 the five-door estate joined the range with production of both versions ending in 2009. The estate was officially marketed as the "Sportwagon” in the United States and was the first Jaguar model designed by Ian Callum. Initially, the X-Type was only available with all-wheel-drive and either a 2.5 litre or 3.0 litre V6 petrol engine. In 2002, an entry-level 2.1 litre V6 front-wheel-drive model was added. All three engines were available with either five-speed automatic or five-speed manual transmissions. The X-Type grille was slightly modified for both the 2004 and 2006 model years.
The X-Type was based on a modified version of the Ford CD132 platform shared with the Ford Mondeo. 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 Jaguar AJ-V6 engine design is unique to the Jaguar X-Type; one notable addition is the use of variable valve timing. The X-Type's petrol engine is also set apart by the use of SFI fuel injection, four 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 also offered in front-wheel drive with the introduction of Jaguar’s first four-cylinder diesel engines (based on the Ford Duratorq ZSD unit from the Mondeo and Transit), and with the smaller 2.1 litre petrol V6. The six-speed automatic transmission supplied on the later 2.2-litre diesel models includes Jaguar Sequential Shift.
