Powertrain & Engine Architecture
At the heart of the 335d xDrive Steptronic lies the BMW N57D30B inline-six diesel engine. This 3.0-liter (2993 cc) engine is a highly refined unit, known for its robust construction and strong performance. It utilizes a sophisticated common-rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. The N57 engine is equipped with a twin-turbocharger setup – a low-pressure turbocharger combined with a high-pressure turbocharger – providing both excellent low-end torque and high-end power. The engine also features variable valve timing (VANOS) and Double-VANOS technology to further enhance efficiency and responsiveness. The engine produces 313 horsepower at 4400 rpm and a substantial 630 Nm (464.66 lb-ft) of torque between 1500 and 2500 rpm. This torque output is a key characteristic of the N57 engine, providing effortless acceleration in real-world driving conditions.
The “Steptronic” transmission refers to BMW’s 8-speed automatic gearbox. This transmission is renowned for its smooth and quick shifts, contributing to both performance and fuel efficiency. It offers a manual shift mode for greater driver control, and features adaptive learning algorithms that adjust shift points based on driving style. The xDrive all-wheel-drive system distributes power between the front and rear axles as needed, enhancing traction and stability, particularly in adverse weather conditions.
Driving Characteristics
The 335d xDrive Steptronic delivers a refined and engaging driving experience. The abundant torque from the N57 engine provides strong acceleration from low speeds, making it ideal for overtaking and merging onto highways. While not as overtly sporty as some of its gasoline-powered siblings, the 335d offers a confident and composed ride. The 8-speed automatic transmission contributes to smooth progress, and the xDrive system provides excellent grip in a variety of conditions. Compared to the 320d, the 335d offers a significant performance upgrade, while the 318d feels noticeably less powerful. The 335d also provides a more relaxed driving experience than the higher-revving gasoline engines, thanks to its plentiful torque.
Equipment & Trim Levels
The 335d xDrive Steptronic typically came well-equipped as a higher-spec variant. Standard features often included leather upholstery, automatic climate control, a premium sound system, and BMW’s iDrive infotainment system with a central display screen. Optional extras could include features like a head-up display, adaptive cruise control, a panoramic sunroof, and upgraded interior trim options. The LCI facelift brought updated styling cues, including revised headlights and taillights, as well as enhancements to the interior design and technology.
Chassis & Braking
The F31 Touring features a sophisticated chassis design, with independent suspension at all four corners. The front suspension utilizes coil springs and struts, while the rear employs a multi-link setup. This configuration provides a good balance between ride comfort and handling precision. The 335d xDrive Steptronic was typically equipped with ventilated disc brakes on all four wheels, providing ample stopping power. ABS (Anti-lock Braking System) and electronic stability control were standard safety features.
Market Reception & Comparison
The 335d xDrive Steptronic was generally well-received by automotive critics. It was praised for its strong performance, refined ride, and practical estate car body style. Fuel economy was also a strong point, with combined fuel consumption figures in the range of 5.7-5.6 l/100 km (41.3 – 42 US mpg). Compared to other premium estate cars in its class, such as the Audi A6 Avant and Mercedes-Benz E-Class Estate, the 335d offered a compelling combination of performance, efficiency, and driving dynamics. However, some critics noted that the diesel engine could be slightly noisy compared to gasoline alternatives.
Legacy
The N57 engine has proven to be a durable and reliable powerplant, and the 335d xDrive Steptronic remains a popular choice in the used car market. While diesel engines have faced increased scrutiny in recent years, the N57 continues to be regarded as a relatively clean and efficient diesel engine. Regular maintenance, including timely oil changes and filter replacements, is crucial for ensuring the long-term reliability of this powertrain. The F31 335d xDrive Steptronic offers a practical and enjoyable driving experience, making it a desirable option for buyers seeking a premium estate car with strong performance and all-weather capability.
