Description
The Daimler Double Six HE was a distinguished and highly refined luxury saloon that represented the pinnacle of British motoring elegance during the 1980s. Built on the Jaguar XJ12 platform, it carried the Daimler name to signify a higher level of finish, craftsmanship, and exclusivity. The “HE” designation stood for “High Efficiency”, referring to a major update to the 5.3-litre V12 engine that improved both fuel economy and performance.
Introduced in 1981, the Double Six HE featured the re-engineered V12 with redesigned “Fireball” cylinder heads developed by Swiss engineer Michael May. These enhancements led to a significant increase in thermal efficiency, allowing for better fuel consumption without sacrificing the smooth, effortless power delivery that the V12 engine was known for. The engine remained one of the quietest and most refined of its kind, offering near-silent operation and abundant torque across the rev range.
Visually, the Daimler Double Six HE retained the elegant silhouette of the Series III Jaguar XJ body, styled by Pininfarina. The Daimler version was subtly differentiated by its traditional fluted chrome grille, distinctive badges, and tasteful detailing that conveyed luxury without ostentation. Most models were built on the long-wheelbase platform, which gave the car a more balanced profile and improved rear-seat comfort.
The interior was a key selling point, designed to evoke a sense of traditional British craftsmanship. High-grade Connolly leather upholstery, hand-polished burr walnut veneers, and thick Wilton carpets created a cabin environment that was both sumptuous and serene. Many models were fitted with fold-down picnic tables in the rear, along with optional features such as individual reading lamps, lambswool rugs, and upgraded audio systems.
Driving the Daimler Double Six HE was an experience defined by its remarkable refinement. The V12 engine delivered seamless acceleration, while the ride quality was soft and composed, aided by independent suspension and power-assisted steering. The standard automatic transmission further added to the car’s relaxed and effortless character, making it an ideal long-distance cruiser.
Throughout its production run, the Double Six HE became a symbol of quiet prestige. It appealed to senior executives, diplomats, and those who appreciated traditional luxury and understated style. Although production was never high, it remained a mainstay in the Daimler lineup until it was eventually succeeded by the more modern XJ40-based Double Six in the early 1990s.
Today, the Daimler Double Six HE is regarded as a classic that combines the smooth charm of a V12 with a level of interior refinement and ride comfort that few cars of its time could match. Its blend of performance, elegance, and exclusivity continues to make it a cherished example of British automotive heritage.
