Powertrain & Engine Architecture
The heart of the M550d xDrive Steptronic is BMW’s N57D30C inline-six diesel engine. This engine is renowned for its sophisticated triple-turbocharger setup, consisting of one variable geometry turbocharger and two smaller turbochargers. This configuration minimizes turbo lag and delivers a broad, flat torque curve. The engine utilizes a common rail direct injection system, injecting fuel at extremely high pressures for optimized combustion. The N57 engine family is known for its robust construction and ability to handle significant power upgrades. The 8-speed Steptronic automatic transmission is a crucial component, designed to handle the substantial torque output of the engine. It features smooth and quick shifts, contributing to both performance and efficiency. The transmission also incorporates features like adaptive shift programs and paddle shifters for driver control.
Driving Characteristics
The M550d xDrive Steptronic delivers a unique driving experience. The prodigious 740 Nm (545.8 lb-ft) of torque available from just 2000 rpm provides effortless acceleration in virtually any gear. The xDrive all-wheel-drive system ensures excellent traction, particularly in adverse weather conditions. While not as overtly sporty as some of its gasoline-powered siblings, the M550d offers a refined and powerful driving experience. The 0-60 mph time of around 4.7 seconds is impressive for a large wagon. The automatic transmission is well-tuned, providing smooth shifts during normal driving and responsive downshifts when needed. Compared to the 528i or 535i models, the M550d prioritizes torque and fuel efficiency over outright horsepower, making it ideal for long-distance cruising and towing.
Equipment & Trim Levels
The M550d xDrive Steptronic came generously equipped as standard. Typical features included leather upholstery, power-adjustable front seats with memory function, a premium sound system, navigation, and a comprehensive suite of safety features. Optional extras included features like adaptive cruise control, a head-up display, ventilated front seats, and a rear-seat entertainment system. The interior design was characterized by BMW’s typical focus on quality materials and ergonomics. The LCI facelift brought subtle updates to the interior, including revised trim options and updated infotainment system graphics.
Chassis & Braking
The F11 Touring chassis was specifically tuned to handle the increased weight and power of the M550d. It features a double-wishbone front suspension and an independent multi-link rear suspension. The suspension setup provides a good balance between comfort and handling. The M550d was equipped with ventilated disc brakes on all four wheels, providing ample stopping power. The electronic stability control system (DSC) and traction control system (TCS) work in conjunction with the xDrive all-wheel-drive system to maintain stability and control in various driving conditions.
Market Reception & Comparison
The M550d xDrive Steptronic was generally well-received by automotive critics. It was praised for its impressive performance, fuel efficiency, and luxurious interior. However, some critics noted that the diesel engine lacked the refinement and sound of a comparable gasoline engine. Compared to other trims in the 5 Series Touring lineup, the M550d offered a significant performance advantage but came at a higher price point. Its fuel economy was comparable to the 520d and 525d models, but its torque output was substantially higher.
Legacy
The N57 engine family, including the N57D30C found in the M550d, has proven to be remarkably reliable. While diesel engines can be susceptible to issues with the diesel particulate filter (DPF) and turbochargers, the N57 has generally demonstrated good longevity with proper maintenance. On the used car market, the F11 M550d xDrive Steptronic remains a desirable option for buyers seeking a high-performance, practical wagon. Its combination of luxury, performance, and fuel efficiency continues to appeal to enthusiasts and discerning drivers alike. However, potential buyers should be aware of the higher maintenance costs associated with a complex diesel engine and the potential for issues with the DPF system.
