2020-2024 BMW 5 Series Touring (G31 LCI facelift ) 520d (190 Hp) Mild Hybrid Steptronic

The BMW 5 Series Touring (G31 LCI), specifically the 520d variant with 190 horsepower and the Steptronic automatic transmission, represents a significant iteration of BMW’s long-running executive wagon. Introduced in July 2020 as part of the Life Cycle Impulse (LCI) facelift for the G31 generation, this model blended practicality with BMW’s signature driving dynamics and a move towards mild hybridization. Production continued through February 2024. Positioned as a mid-range offering within the 5 Series Touring lineup, the 520d aimed to provide a balance between fuel efficiency, reasonable performance, and a comfortable driving experience for families and business users alike. It competed directly with other premium estate cars like the Audi A6 Avant and Mercedes-Benz E-Class Estate.

Technical Specifications

Powertrain & Engine Architecture

The heart of the 520d Touring LCI is the BMW B47D20B, a 2.0-liter inline-four cylinder diesel engine. This engine is a member of BMW’s modular engine family, known for its efficiency and refinement. The ‘B47’ designation indicates a diesel engine, ‘D20’ signifies a displacement of approximately 2.0 liters, and ‘B’ denotes the latest generation. The engine utilizes a second-generation common rail direct fuel injection system operating at extremely high pressures (2,500 bar) for optimized combustion. A twin-scroll turbocharger with variable geometry turbine (VGT) technology provides a broad torque curve and minimizes turbo lag. The engine also features an intercooler to further enhance performance. The mild hybrid system, a 48V setup, incorporates a starter-generator that assists the engine during acceleration and allows for extended coasting with the engine switched off, improving fuel economy. The Steptronic 8-speed automatic transmission is a crucial component, offering smooth and quick gear changes. It’s programmed for efficiency but can be manually shifted via steering wheel paddles or the gear selector.

Driving Characteristics

The 520d Touring LCI delivers a composed and refined driving experience. While not overtly sporty, the 190 hp and 295 lb-ft of torque provide adequate performance for everyday driving and long-distance cruising. Acceleration from 0-60 mph takes around 7.2 seconds. The Steptronic transmission is well-matched to the engine, providing seamless gear changes and contributing to a relaxed driving style. Compared to higher-output 5 Series variants like the 530d or 540i, the 520d feels less urgent in its acceleration. However, the mild hybrid system helps to fill in torque gaps and provides a noticeable boost during overtaking maneuvers. The gear ratios are tuned for fuel efficiency, meaning the engine doesn’t rev as high as in sportier models. The rear-wheel-drive configuration contributes to balanced handling, although it can be less confident in slippery conditions compared to xDrive all-wheel-drive models.

Equipment & Trim Levels

The 520d Touring LCI typically came well-equipped as standard. Features included BMW’s iDrive infotainment system with a touchscreen display, navigation, automatic climate control, leather upholstery, and a suite of driver-assistance systems such as lane departure warning and collision warning. Optional extras included a head-up display, premium sound system, adaptive cruise control, and various interior trim options. Specific trim levels (Luxury Line, Sport Line, M Sport) offered different aesthetic enhancements, such as unique alloy wheel designs, interior trim materials, and exterior styling cues. The standard interior featured high-quality materials and a comfortable, ergonomic layout. The rear seats offered ample space for passengers, and the large cargo area (560-1700 liters) provided excellent practicality.

Chassis & Braking

The G31 Touring utilizes a sophisticated chassis design. The front suspension employs a double-wishbone setup, while the rear features an independent multi-link suspension. This configuration provides a good balance between ride comfort and handling precision. The 520d typically came equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock Braking System (ABS), Dynamic Stability Control (DSC), and other electronic stability systems are standard. The suspension tuning is geared towards comfort, but the M Sport suspension option offered a firmer ride and improved handling characteristics. The steering is precise and well-weighted, providing good feedback to the driver.

Market Reception & Comparison

The 520d Touring LCI was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and spacious interior. Critics noted that while it wasn’t the most exciting car to drive, it offered a compelling blend of practicality and refinement. Compared to the more powerful 5 Series variants, the 520d offered significantly better fuel economy. The 530d, for example, provided more performance but at the cost of increased fuel consumption and emissions. The 520d also represented a more affordable entry point into the 5 Series Touring range. Reliability reports suggest that the B47 engine is generally robust, although some owners have reported issues with the diesel particulate filter (DPF) and turbocharger.

Legacy

The BMW 520d Touring (G31 LCI) represents a well-rounded and practical executive wagon. Its combination of fuel efficiency, comfort, and technology has made it a popular choice in the used car market. The B47 engine, while not without its potential issues, has proven to be relatively durable when properly maintained. As a mild hybrid, it foreshadowed BMW’s broader push towards electrification. Today, these models offer a compelling value proposition for buyers seeking a spacious, comfortable, and efficient premium estate car.
