The 1983 Jaguar XJ (XJ40), often regarded as a pivotal model in Jaguar's history, marks the brand's transition from the traditional, luxurious saloon of the Series III to a more modern and technically sophisticated vehicle. This generation introduced a completely new platform, dubbed XJ40, featuring a monocoque chassis and independent suspension on all four wheels, a significant departure from the live rear axle of its predecessors. The XJ40 was also the first Jaguar to incorporate fuel injection across the range, replacing the carburetor system of previous models. This technological leap, combined with a streamlined aerodynamic design, resulted in a car that was both more efficient and more powerful.

The 1983 XJ40 offered a range of powerful and refined engines, including the iconic 3.6-liter inline six-cylinder engine, which delivered smooth and effortless acceleration. The later addition of the 4.0-liter and 4.2-liter variants further enhanced the car's performance. The XJ40 also boasted a luxurious interior that was meticulously crafted with high-quality materials and attention to detail. Features like sumptuous leather upholstery, walnut veneer trim, and a sophisticated climate control system epitomized the Jaguar brand's reputation for opulence and comfort. Despite its sophistication, the XJ40 faced some initial reliability challenges, a common issue for first-generation models incorporating new technologies. However, these issues were gradually addressed by Jaguar, solidifying the XJ40's place as a worthy successor to the iconic XJ lineage.
