INTRODUCTION
The 525d Touring, built on the G31 platform, offered a practical and luxurious option for buyers needing the space of a wagon without sacrificing the BMW driving experience. Production ran from 2017 through 2020, representing a mid-cycle offering within the G31’s overall lifespan. The G31 platform itself was a significant evolution, utilizing a combination of steel, aluminum, and carbon fiber reinforced plastic (CFRP) in its construction to reduce weight and improve rigidity. This focus on lightweighting contributed to improved handling and fuel efficiency. The 525d specifically targeted buyers who prioritized fuel economy and comfortable long-distance cruising over outright performance, making it a popular choice in European markets.
Powertrain & Engine Architecture
At the heart of the 525d Touring lies 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 utilizes a sophisticated common-rail direct injection system, operating at extremely high pressures (2,000 bar) to ensure precise fuel delivery and optimized combustion. A single twin-scroll turbocharger, coupled with an intercooler, provides boost to enhance power and torque. The engine also features variable valve timing (VANOS) and variable turbine geometry (VTG) on the turbocharger to optimize performance across the rev range. The 525d is paired with BMW’s 8-speed Steptronic automatic transmission. This transmission is renowned for its smooth and quick shifts, contributing to both performance and fuel efficiency. The Steptronic transmission offers both automatic and manual shift modes, allowing the driver to tailor the driving experience to their preferences.
Driving Characteristics
The 525d Steptronic delivers a composed and refined driving experience. While not as overtly sporty as the 540i, it provides ample power for everyday driving and comfortable highway cruising. The 500 Nm (368 lb-ft) of torque, available from just 2000 rpm, provides strong acceleration in most situations. The 8-speed automatic transmission is well-matched to the engine, providing smooth and seamless gear changes. Compared to the 520d, the 525d offers a noticeable increase in performance, while remaining more economical than the 530d. The rear-wheel-drive configuration contributes to balanced handling, although xDrive all-wheel drive was also available as an option. The steering is precise and well-weighted, providing good feedback to the driver.
Equipment & Trim Levels
The 525d Touring typically came well-equipped as standard. Common features included BMW’s iDrive infotainment system with a 10.25-inch touchscreen display, navigation, automatic climate control, leather upholstery, and power-adjustable front seats. Optional extras included features such as a head-up display, panoramic sunroof, premium sound system (Harman Kardon or Bowers & Wilkins), adaptive cruise control, and a variety of driver assistance systems. Interior trim options ranged from fine wood veneers to aluminum accents, allowing buyers to personalize the cabin to their taste. The standard upholstery was typically leatherette, with full leather available as an upgrade.
Chassis & Braking
The G31 5 Series Touring features a sophisticated chassis design. The front suspension utilizes a double-wishbone setup, while the rear employs an independent multi-link suspension. This configuration provides a comfortable ride while maintaining good handling characteristics. The 525d typically came equipped with ventilated disc brakes on all four wheels. Anti-lock braking system (ABS), electronic stability control (ESC), and traction control were standard safety features. The suspension was tuned to provide a balance between comfort and handling, with optional adaptive dampers available for a more customizable ride.
Market Reception & Comparison
The 525d Touring was generally well-received by automotive critics. It was praised for its refined engine, comfortable ride, spacious interior, and practical wagon body style. Compared to the 520d, the 525d offered a noticeable performance upgrade without significantly compromising fuel economy. Against the 530d, it represented a more affordable option, albeit with less power. Fuel economy was a strong point, with combined figures typically ranging from 4.7 to 5.1 l/100 km (50-46.1 US mpg). Reliability was generally good, although some owners reported issues with the diesel particulate filter (DPF) system, particularly on vehicles primarily used for short trips.
Legacy
The BMW 525d Touring (G31) remains a popular choice in the used car market. Its combination of practicality, luxury, and fuel efficiency continues to appeal to buyers. The B47 engine, while generally reliable, requires regular maintenance, including oil changes and DPF regeneration. The 8-speed Steptronic transmission is known for its durability, but proper fluid changes are essential to ensure long-term reliability. Overall, the 525d Touring represents a well-rounded and capable premium wagon that offers a compelling alternative to traditional SUVs.
