1993-1997 Daimler Daimler Double Six 6.0 i V12 (318 Hp)

The Daimler Double Six 6.0i, produced between 1993 and 1997, represents the pinnacle of traditional British luxury motoring under Daimler’s ownership by Jaguar. This variant, powered by a 6.0-liter V12 engine producing 318 horsepower, was the flagship model of the X320 series, the final iteration of the Double Six nameplate before the Daimler brand was fully absorbed into Jaguar. It aimed to provide a supremely comfortable and refined driving experience, appealing to a clientele prioritizing prestige and effortless performance over outright sportiness. The 6.0i distinguished itself from earlier Double Six models with its modernized styling, improved build quality, and advanced (for the time) electronic systems.

Technical Specifications

Powertrain & Engine Architecture

The heart of the Daimler Double Six 6.0i is its 6.0-liter (5993cc) naturally aspirated V12 engine. This engine, internally designated as the AJ12, is a 60-degree V12 featuring aluminum alloy cylinder heads and a cast iron block. It utilizes a Bosch Motronic engine management system controlling fuel injection and ignition. The engine employs a single overhead camshaft per cylinder bank, operating four valves per cylinder. The V12’s smooth operation is a hallmark, delivering power in a linear and refined manner. The 6.0-liter displacement was an increase over previous V12 offerings, contributing to the substantial 318 horsepower and 361 lb-ft of torque. The engine is paired exclusively with a four-speed automatic transmission, a ZF 4HP22 unit, chosen for its smoothness and suitability for the car’s grand touring character. This transmission, while reliable, lacks the responsiveness of more modern gearboxes.

Driving Characteristics

The Daimler Double Six 6.0i delivers a driving experience focused on comfort and effortless cruising. The large displacement V12 provides ample torque throughout the rev range, allowing for brisk acceleration without requiring frequent downshifts. The four-speed automatic transmission, while not particularly sporty, contributes to the smooth and relaxed driving style. The car’s substantial weight (around 4,200 pounds) is noticeable, but well-managed by the sophisticated suspension. Steering is power-assisted and light, prioritizing ease of use over direct feedback. Compared to the Jaguar XJ12 of the same era, the Daimler offered a slightly softer suspension setup and a more opulent interior, further emphasizing its luxury focus. While the 6.0i isn’t a sports sedan, it offers a level of performance that is more than adequate for comfortable high-speed touring. The gear ratios are optimized for relaxed highway cruising, with a focus on minimizing engine noise and maximizing fuel efficiency (relative to the engine’s size and output).

Equipment & Trim Levels

The Daimler Double Six 6.0i was exceptionally well-equipped, reflecting its status as the flagship model. Standard features included Connolly leather upholstery, burled walnut wood trim, power-adjustable front seats with memory function, automatic climate control, a premium sound system, and electric windows and mirrors. Cruise control, a sunroof, and heated seats were also standard. The interior was designed to provide a luxurious and comfortable environment for both driver and passengers. Optional extras included a rear seat entertainment system, upgraded sound systems, and various exterior color options. The Daimler trim level generally featured more extensive wood trim and higher-grade leather than equivalent Jaguar models. The emphasis was on creating a sense of understated elegance and refinement.

Chassis & Braking

The X320 chassis, upon which the Double Six 6.0i is based, represents a significant improvement over previous Jaguar platforms. It features independent suspension all around, with double wishbones at the front and semi-trailing arms at the rear. The suspension is designed to provide a comfortable ride while maintaining good handling characteristics. Anti-roll bars are fitted front and rear to reduce body roll during cornering. Braking is provided by four-wheel disc brakes with ABS (Anti-lock Braking System). The braking system is effective, but the car’s weight requires a firm pedal input. The steering is rack and pinion, providing precise and responsive control. The chassis was engineered to minimize noise, vibration, and harshness, contributing to the car’s overall refinement.

Market Reception & Comparison

The Daimler Double Six 6.0i was generally well-received by automotive critics, who praised its luxurious interior, smooth ride, and powerful V12 engine. However, some critics noted the car’s high price and relatively dated technology compared to some of its German rivals. Compared to the Jaguar XJ12, the Daimler offered a more opulent and refined experience, but at a higher cost. Fuel economy was predictably poor, averaging around 12-15 mpg in mixed driving. Reliability was generally good, but the complex V12 engine and associated electronics required regular maintenance. The Daimler appealed to a niche market of buyers who valued traditional British luxury and were willing to pay a premium for it. It was often seen as a more exclusive and prestigious alternative to the Jaguar XJ12.

Legacy

The Daimler Double Six 6.0i represents the last hurrah of the traditional Daimler brand before its complete integration into Jaguar. Today, these cars are sought after by collectors and enthusiasts who appreciate their classic British charm and powerful V12 engines. While maintenance can be expensive due to the car’s age and complexity, the Double Six 6.0i remains a rewarding and enjoyable vehicle to own. The AJ12 V12 engine, while demanding in terms of maintenance, is known for its durability and smooth operation when properly cared for. The car’s elegant styling and luxurious interior have ensured its enduring appeal. In the used car market, well-maintained examples command premium prices, reflecting their rarity and desirability. The Double Six 6.0i stands as a testament to a bygone era of British automotive engineering and luxury.
