2017-2019 BMW 5 Series Touring (G31) 520d (190 Hp) Steptronic

The BMW 5 Series Touring (G31) 520d Steptronic, produced from 2017 to October 2019, represents a compelling blend of practicality and efficiency within the sixth generation of the iconic 5 Series. Positioned as a mid-range offering in the Touring (estate) body style, this variant catered to buyers seeking a refined driving experience coupled with the versatility of a wagon. It slots below the more powerful 530d and 540i models, offering a balance between performance and fuel economy. The G31 generation, built on the 3 Series (F30) platform, aimed to deliver a more spacious and technologically advanced experience than its predecessor.

Technical Specifications

Powertrain & Engine Architecture

The 520d Touring utilizes BMW’s B47D20B 2.0-liter inline-four cylinder diesel engine. This engine is a member of the modular BMW engine family, known for its efficiency and refinement. The B47 features a common-rail direct injection system operating at pressures up to 2,000 bar, ensuring precise fuel delivery and optimized combustion. A single twin-scroll turbocharger with variable geometry turbine (VGT) technology provides enhanced responsiveness and power delivery across the rev range. The engine also incorporates advanced technologies like solenoid injectors and a closed-deck engine block for increased durability. The Steptronic 8-speed automatic transmission is a crucial component, offering smooth and efficient gear changes. It features a torque converter and allows for both automatic and manual shifting via steering wheel-mounted paddles. The transmission is programmed to prioritize fuel efficiency while still providing adequate performance when needed.

Driving Characteristics

The 520d Steptronic delivers a comfortable and composed driving experience. While not overtly sporty, the 190 horsepower and 400 Nm (295 lb-ft) of torque provide sufficient power for everyday driving and highway cruising. Acceleration from 0-60 mph takes approximately 7.4 seconds. The eight-speed automatic transmission contributes to relaxed cruising, with well-chosen gear ratios that keep the engine within its optimal power band. Compared to the more powerful 530d, the 520d feels less urgent in acceleration, but it offers a more fuel-efficient and affordable option. The rear-wheel-drive configuration provides balanced handling, although it can be less confident in slippery conditions compared to xDrive all-wheel-drive models.

Equipment & Trim Levels

The 520d Touring typically came standard with features such as BMW’s iDrive infotainment system with a 10.25-inch touchscreen display, automatic climate control, power-adjustable front seats, and a leather-wrapped steering wheel. Standard safety features included automatic emergency braking, lane departure warning, and a rearview camera. Optional extras included features like a head-up display, premium sound system, adaptive cruise control, and a panoramic sunroof. Interior upholstery options ranged from standard cloth to premium leather. Trim levels varied by market, but generally offered packages that bundled popular options together.

Chassis & Braking

The G31 5 Series Touring features a double-wishbone front suspension and an independent multi-link rear suspension, providing a comfortable ride and precise handling. The suspension is tuned to balance comfort and control, absorbing bumps effectively while maintaining stability in corners. The 520d typically came equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) and electronic stability control (ESC) are standard features, enhancing safety and control in various driving conditions. The chassis is constructed using a mix of high-strength steel and aluminum, contributing to both rigidity and weight reduction.

Market Reception & Comparison

The 520d Touring was generally well-received by automotive critics, praised for its fuel efficiency, comfortable ride, and spacious interior. It was seen as a practical and sensible choice for buyers who prioritized versatility and economy over outright performance. Compared to the 530d, the 520d offered a lower price point and better fuel economy, making it a more attractive option for budget-conscious buyers. However, some critics noted that the 520d’s performance could feel somewhat underwhelming, especially when fully loaded or traveling uphill. Its fuel economy figures consistently ranked among the best in its class.

Legacy

The B47 engine, found in the 520d Touring, has proven to be a relatively reliable powertrain, although some early models experienced issues with timing chain wear. Regular maintenance, including oil changes and timing chain inspections, is crucial for long-term reliability. On the used car market, the 520d Touring remains a popular choice, offering a good balance of practicality, comfort, and fuel efficiency. Its reputation for reliability and relatively low running costs contribute to its continued appeal. The G31 generation 5 Series Touring is considered a significant step forward in terms of technology and refinement, solidifying its position as a benchmark in the executive estate segment.
