Description
The Daimler Double Six HE Series III was a luxurious and mechanically refined version of Daimler’s flagship V12 saloon, produced during the 1980s and early 1990s. It represented the pinnacle of the Daimler-Jaguar collaboration, blending advanced engineering with a high level of traditional craftsmanship. The HE designation stood for “High Efficiency”, referring to improvements made to the engine to enhance performance and fuel economy.
This model was based on the long-wheelbase Jaguar XJ12 Series III, featuring subtle but significant Daimler distinctions. It retained the elegant lines of the Pininfarina-styled Series III bodywork, with its slimmer roof pillars and slightly raised roofline contributing to a more graceful and contemporary appearance. The Daimler version was distinguished by a fluted chrome grille, unique wheel designs, and understated Daimler badging, giving it a more dignified and exclusive look.
Under the bonnet lay the 5.3-litre Jaguar V12 engine, which in HE form was modified with redesigned cylinder heads and a higher compression ratio. These changes improved fuel efficiency and extended the car’s cruising range, while preserving the V12’s renowned smoothness and quietness. Power delivery was refined and continuous, making the car ideally suited for relaxed high-speed touring. The standard automatic transmission complemented the engine’s characteristics with smooth, unobtrusive gear changes.
The interior was a showcase of luxury. Deep Connolly leather upholstery, polished burr walnut veneers, thick carpeting, and rear picnic tables (in some versions) gave the cabin a club-like atmosphere. The long-wheelbase configuration allowed for generous rear legroom, while sound insulation kept the interior impressively quiet. Attention to detail was apparent throughout, from the chrome-plated interior fittings to the softly illuminated instrumentation and optional lambswool rugs.
As one of the last Daimler saloons to feature a V12 engine, the Double Six HE Series III marked the end of an era for the brand. It was aimed at a discerning clientele who valued refinement, tradition, and smooth performance over overt displays of power or styling. The car was also used in official and diplomatic fleets, further underscoring its status.
Today, the Daimler Double Six HE Series III is remembered as a refined and dignified classic. It stands as a tribute to the craftsmanship and engineering philosophy of its time, offering a uniquely British interpretation of the luxury saloon that combined silent V12 performance with a richly appointed cabin and timeless design.
