The Land Rover Discovery III 2.7 TDI Automatic, produced from 2004 to 2009, represented a significant step forward for the Discovery line. Positioned as a mid-range offering within the third-generation (L319) Discovery series, it aimed to balance capability with improved on-road refinement and fuel efficiency compared to the petrol options. This variant utilized a modern turbodiesel engine paired with a six-speed automatic transmission, making it a popular choice for those seeking a versatile and comfortable SUV. The Discovery III, overall, was a crucial model for Land Rover, bridging the gap between the rugged off-road focus of previous generations and the increasing demand for a more family-friendly, all-weather vehicle.

Powertrain & Engine Architecture
The heart of the Discovery III 2.7 TDI Automatic is the 276DT engine, a 2.7-liter V6 turbodiesel. This engine was sourced from Jaguar and represents a significant upgrade over the older five-cylinder diesels previously offered in the Discovery. It features a common rail direct injection system, delivering fuel at extremely high pressure for improved combustion efficiency and reduced emissions. The engine utilizes a single variable geometry turbocharger (VGT) and an intercooler to boost power and torque. The DOHC valvetrain, with four valves per cylinder, further enhances breathing and performance. The six-speed automatic transmission, a ZF 6HP26, was a key component, offering smooth shifts and contributing to the vehicle’s refined driving experience. This transmission was known for its durability and adaptability to both on-road and off-road conditions.
Driving Characteristics
The 2.7 TDI Automatic provided a noticeable step up in performance compared to earlier Discovery models. While not a sports car, the 190 horsepower and 324 lb-ft of torque delivered adequate acceleration for everyday driving and towing. The automatic transmission, while smooth, could sometimes feel hesitant during quick overtaking maneuvers. The gear ratios were tuned for a balance between fuel economy and usability, with a focus on providing strong low-end torque for off-road situations. Compared to the manual transmission versions of the 2.7 TDI, the automatic offered greater convenience, but at the expense of some responsiveness. Higher-output versions of the 2.7 TDI (200 hp) and the 3.0-liter SDV6 offered significantly more performance, but also came with a higher price tag and increased running costs.
Equipment & Trim Levels
The 2.7 TDI Automatic typically came equipped with a respectable level of standard features. These included climate control, electric windows and mirrors, alloy wheels, and a basic audio system. Higher trim levels, such as the HSE, added features like leather upholstery, heated seats, a premium audio system, and parking sensors. Optional extras included a sunroof, satellite navigation, and upgraded suspension systems. Interior upholstery was generally cloth on base models, with leather available as an upgrade. The dashboard layout was functional and relatively straightforward, prioritizing usability over outright luxury.
Chassis & Braking
The Discovery III utilized a robust body-on-frame construction, providing excellent strength and off-road capability. The suspension system consisted of double wishbones at both the front and rear, offering a comfortable ride and good articulation for off-road use. Brakes were ventilated discs all around, providing ample stopping power. ABS (Anti-lock Braking System) was standard. The 2.7 TDI models, due to their increased weight compared to petrol versions, often featured slightly stiffer suspension settings to maintain handling stability. Stabilizer bars were fitted front and rear to reduce body roll during cornering.
Market Reception & Comparison
The Discovery III 2.7 TDI Automatic was generally well-received by automotive critics. It was praised for its comfortable ride, spacious interior, and capable off-road performance. However, some critics noted the relatively high fuel consumption compared to more modern SUVs and the occasional hesitation from the automatic transmission. Compared to the 2.5-liter TDI models, the 2.7 TDI offered a significant improvement in power and refinement. Against competitors like the BMW X5 and Mercedes-Benz ML-Class, the Discovery III offered a more rugged and practical alternative, albeit with a slightly less luxurious interior.
Legacy
The 2.7 TDI engine, while generally reliable, has been known to exhibit some common issues over time, including potential problems with the turbocharger and fuel injectors. The ZF 6HP26 automatic transmission is considered very durable, but requires regular fluid changes to maintain optimal performance. Today, the Discovery III 2.7 TDI Automatic represents a relatively affordable entry point into Land Rover ownership. Well-maintained examples are still sought after by enthusiasts who appreciate their blend of capability, comfort, and practicality. The model’s robust construction and readily available parts supply contribute to its continued presence on the used car market.
