1994: XJS receives the new improved AJ16 4.0L engine
January
After 3 years of supply from VPL it was decided that the commercial benefits to be gained from moving Jaguars body panel pressings to Ford’s Halewood factory was to big an opportunity to ignore. Since the 1963 Anglia 105 Halewood had the ability to produce cars from sheets of metal to fully assembled cars all on the one site. Halewood produced all body panels for Jaguar XJ, XJS and XK8 until the (2000s) when Castle Bromwich took over the process. In 2000 Ford changed the factory from the Escort production to the X-TYPE. All X-TYPEs were produced there until 2010 at the end of production.

In the summer of 1994 the AJ6 engine was replaced by the AJ16 4.0 litre engine as fitted to the new X300 saloon, the idea behind the new engine was to improve performance and fuel economy, as well as meeting stricter standards for emission control. The AJ16 engine was fitted with a magnesium cam cover.

Internal changes to the 4.0 litre models included: Seat panels in cloth with shallow grain leather facings. The external 6.0 litre model changes included: Chrome headlamp surrounds; black radiator grille; Twin coachlines; New badges on front wings; New 16in 20-spoke alloy wheels with eggshell painted inner faces. Internal changes to the 6.0 litre included: Autolux leather to the same design but ruched in style with contrasting piping and stitching; Full leather centre console; Leather door trim; Burr walnut veneer with matchwood inlay; Walnut gearshift lever knob.
