Description
The Daimler Six 4.0 was a premium luxury saloon produced by Jaguar Cars under the Daimler nameplate during the 1990s. Introduced in 1994, it was based on the Jaguar X300 platform and represented the highest specification version of the six-cylinder Jaguar XJ series. The Daimler Six combined traditional British craftsmanship with modern engineering, offering smooth performance, a refined driving experience, and the dignified styling long associated with the Daimler brand.
Visually, the Daimler Six 4.0 shared its bodywork with the Jaguar XJ, but subtle differences marked it out as something special. The signature fluted Daimler radiator grille, discreet badges, extra chrome accents, and unique alloy wheels gave it a more stately and distinguished appearance. It was almost always produced in the long-wheelbase configuration, which gave the car an elegant profile and provided additional space and comfort for rear-seat passengers.
Power came from the 4.0-litre AJ16 inline-six engine, an updated and refined version of Jaguar’s proven AJ6 engine. It delivered smooth, linear power with minimal vibration, perfectly complementing the car’s luxury-oriented character. The engine was paired with a four-speed automatic transmission, providing effortless cruising and quiet, seamless gear changes. The driving experience was focused on comfort and composure rather than outright performance, with supple suspension and excellent insulation from road and engine noise.
The interior was a showcase of luxury and attention to detail. High-grade Connolly leather upholstery, hand-finished burr walnut veneer, thick carpeting, and rear picnic tables were standard features. The dashboard layout was classic and restrained, with soft-touch materials and analog dials. Rear passengers benefited from generous legroom, individual reading lights, and often optional extras like lambswool over-rugs and powered rear seats.
The Daimler Six 4.0 occupied a unique space in the luxury saloon market. While it shared much of its engineering with Jaguar’s XJ6, its additional refinement, hand-finished details, and exclusivity appealed to buyers who wanted understated luxury with traditional British style. It also found favour among executives and official use, often serving in diplomatic and ceremonial roles.
Production of the Daimler Six 4.0 continued until 1997, when the X300 series was replaced by the X308, which brought V8 engines to the range. With its blend of smooth six-cylinder power, elegant design, and a cabin steeped in craftsmanship, the Daimler Six 4.0 remains a cherished example of 1990s British luxury motoring. It is increasingly appreciated as a modern classic, especially by those who admire the quiet dignity and heritage the Daimler name represents.
