The Daimler Super Eight 4.2i V8 32V, produced between 2005 and 2009, represented a significant offering in the luxury sedan segment. Positioned as the flagship model for the revived Daimler brand (following its acquisition by Tata Motors), the Super Eight aimed to recapture the prestige and engineering excellence associated with the historic Daimler name. It was built on a platform shared with Jaguar, specifically utilizing the XJ-based architecture, but distinguished itself through unique styling and a focus on British craftsmanship. This particular 4.2-liter supercharged V8 variant was the top-tier engine option, offering a blend of performance and refinement intended to compete with established German luxury brands.

Powertrain & Engine Architecture
The heart of the Super Eight 4.2i was the 4.2-liter supercharged V8 engine, designated as the AJ34S. This engine was originally developed by Jaguar and shared with Land Rover, but Daimler engineers refined it to deliver a unique driving experience. The engine featured a 90-degree V8 configuration with four valves per cylinder, operated by double overhead camshafts. The supercharger, a Lysholm-type twin-screw unit, provided forced induction, significantly boosting power and torque output. An intercooler was integrated into the intake manifold to reduce intake air temperature, further enhancing performance and efficiency. Fuel delivery was managed by a multi-port fuel injection system, ensuring precise fuel metering for optimal combustion. The engine’s architecture prioritized smoothness and refinement, with careful attention paid to noise, vibration, and harshness (NVH) characteristics. The engine was longitudinally mounted in the front of the vehicle, driving the rear wheels.
Driving Characteristics
The Super Eight 4.2i delivered a distinctly grand touring experience. The supercharger provided immediate throttle response and a broad torque curve, resulting in effortless acceleration. While not overtly sporty, the 400 horsepower output allowed for brisk performance, with 0-60 mph times estimated around 5.7 seconds. The six-speed automatic transmission, sourced from ZF, was tuned for smooth and seamless gear changes, prioritizing comfort over aggressive shifting. The transmission offered a manual shift mode, but it was primarily intended for relaxed cruising. The car’s weight, approximately 4,100 pounds, contributed to a stable and planted feel on the road. The suspension, tuned for comfort, absorbed bumps and imperfections effectively, providing a luxurious ride quality. Steering was precise and well-weighted, but lacked the direct feedback found in more performance-oriented sedans.
Equipment & Trim Levels
The Daimler Super Eight 4.2i was comprehensively equipped as standard. Interior appointments included Connolly leather upholstery, wood veneer trim, and a premium audio system. Standard features included automatic climate control, heated front and rear seats, power-adjustable seats with memory function, and a sunroof. The dashboard featured a classic analog instrument cluster combined with a modern infotainment system. Optional extras included a rear seat entertainment system, upgraded leather options, and a bespoke luggage set. The overall interior ambiance was one of understated elegance and British luxury. Exterior styling was characterized by a traditional Daimler grille, chrome accents, and a long, flowing silhouette.
Chassis & Braking
The Super Eight utilized a modified version of the Jaguar XJ’s chassis, featuring independent double wishbone suspension at all four corners. This suspension setup provided a comfortable ride and good handling characteristics. The car was equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock Braking System (ABS) and Electronic Stability Control (ESC) were standard safety features. The rear suspension incorporated self-leveling air springs to maintain a consistent ride height regardless of load. Stabilizer bars were fitted front and rear to reduce body roll during cornering. The steering system was a power-assisted rack-and-pinion setup.
Market Reception & Comparison
The Daimler Super Eight 4.2i received generally positive reviews from automotive critics. It was praised for its luxurious interior, comfortable ride, and powerful engine. However, some critics noted that it lacked the dynamic sharpness of its German rivals, such as the BMW 7 Series and Mercedes-Benz S-Class. Fuel economy was also a concern, with combined fuel consumption averaging around 18 mpg. Compared to the standard 4.2-liter naturally aspirated version of the engine, the supercharged variant offered a significant performance boost, but at the expense of slightly increased fuel consumption. The Super Eight aimed to appeal to buyers seeking a traditional British luxury experience, prioritizing comfort and refinement over outright performance.
Legacy
The Daimler Super Eight 4.2i represents a unique chapter in Daimler’s history. While production numbers were relatively low, the car has gained a following among collectors and enthusiasts who appreciate its blend of British craftsmanship and modern technology. The AJ34S engine, while shared with Jaguar and Land Rover, proved to be a robust and reliable powerplant when properly maintained. Today, well-maintained examples of the Super Eight 4.2i command respectable prices in the used car market. The car’s long-term reliability is generally good, although preventative maintenance, particularly regarding the supercharger and cooling system, is crucial. The Super Eight serves as a reminder of Daimler’s ambition to revive its legacy as a purveyor of luxury automobiles.
