Powertrain & Engine Architecture
The heart of the 520d Steptronic is the N47D20C 2.0-liter inline-four diesel engine. This engine was a cornerstone of BMW’s EfficientDynamics strategy, focusing on maximizing fuel economy and reducing emissions. The N47 series, introduced in 2007, was notable for its second-generation common rail direct injection system, operating at pressures up to 1,800 bar. This high-pressure injection, combined with a variable geometry turbocharger and intercooler, allowed for a good balance of power and efficiency. The engine also featured four valves per cylinder and a timing chain. The Steptronic transmission is an eight-speed automatic gearbox, known for its smooth shifts and efficiency. It offered both automatic and manual shift modes, allowing drivers to tailor the driving experience to their preferences. The transmission’s wide gear ratio spread contributed to both fuel economy and responsiveness.
Driving Characteristics
The 520d Steptronic, with its 184 horsepower and 380 Nm (280 lb-ft) of torque, offered respectable performance for a large grand tourer. Acceleration from 0 to 60 mph took around 8.5 seconds, and top speed was limited to 132.35 mph. While not a sports car, the engine provided sufficient power for comfortable highway cruising and overtaking. The eight-speed automatic transmission played a crucial role in optimizing performance and fuel economy. The gear ratios were well-spaced, allowing the engine to operate efficiently at various speeds. Compared to the more powerful 535i or 550i models, the 520d prioritized fuel efficiency and comfort over outright speed. It also differed from the 520d with a manual transmission, offering a more relaxed and convenient driving experience, albeit with slightly reduced fuel economy.
Equipment & Trim Levels
The 520d Steptronic typically came equipped with a generous array of standard features. These included automatic climate control, power-adjustable front seats, a multi-function steering wheel, and a BMW Professional radio system. Upholstery was typically cloth or leatherette, with leather being an optional upgrade. Common optional extras included a navigation system, a premium sound system, parking sensors, and a panoramic sunroof. The Gran Turismo’s defining feature was its spacious interior and versatile seating configuration. The rear seats could be folded down to create a large cargo area, making it suitable for carrying bulky items. The split tailgate, with its upper and lower sections, further enhanced practicality.
Chassis & Braking
The F07 Gran Turismo featured a double-wishbone front suspension and an independent multi-link rear suspension, providing a comfortable and controlled ride. The suspension was tuned to prioritize comfort over sporty handling, reflecting the car’s grand touring character. The 520d Steptronic was equipped with ventilated disc brakes on all four wheels, providing adequate stopping power. Anti-lock braking system (ABS) and electronic stability control (ESC) were standard safety features. The weight distribution was relatively balanced, contributing to stable handling. The 520d, being one of the lighter variants, benefited from slightly more agile handling compared to the heavier six-cylinder models.
Market Reception & Comparison
The 5 Series Gran Turismo, and the 520d Steptronic in particular, received mixed reviews from automotive critics. While praised for its spacious interior, comfortable ride, and fuel efficiency, it was often criticized for its unconventional styling and somewhat compromised handling. Some reviewers found the Gran Turismo to be too large and cumbersome, lacking the sporty feel of the traditional 5 Series sedan. Compared to other trims, the 520d offered the best fuel economy, making it an attractive option for buyers prioritizing running costs. However, its performance was noticeably slower than the more powerful variants. The 520d also represented a more affordable entry point into the 5 Series Gran Turismo range, appealing to a wider range of buyers.
Legacy
The N47D20C engine, while generally reliable, has been known to experience issues with the timing chain and turbocharger in some cases. Regular maintenance and timely replacement of worn components are crucial for ensuring long-term reliability. The 520d Steptronic, as a relatively common variant, benefits from readily available parts and a well-established network of BMW service centers. In the used car market, the F07 5 Series Gran Turismo, including the 520d Steptronic, represents a relatively affordable option for buyers seeking a spacious and comfortable grand tourer. Its fuel efficiency and practicality continue to appeal to those looking for a versatile and economical vehicle.
