The BMW 3 Series Gran Turismo (F34) 320d, produced from 2013 to 2015, represented BMW’s attempt to blend the practicality of a hatchback with the perceived prestige of the 3 Series sedan. Positioned as a more spacious and versatile alternative to the standard 3 Series Touring (wagon) and sedan, the F34 Gran Turismo aimed to capture buyers seeking a premium, five-door vehicle. The 320d variant, powered by a 2.0-liter turbocharged diesel engine producing 184 horsepower, served as the entry point into the Gran Turismo range, offering a balance of fuel efficiency and acceptable performance. It was a key model in the F34 lineup, targeting European markets primarily, where diesel engines and practical body styles were highly favored.

Powertrain & Engine Architecture
The heart of the 320d Gran Turismo is the BMW N47D20C engine, a 2.0-liter inline-four cylinder diesel. This engine is a member of BMW’s highly successful N47 family, known for its efficiency and refinement. The N47D20C utilizes a second-generation common rail direct injection system, delivering fuel at pressures up to 1800 bar for optimized combustion. A single twin-scroll turbocharger with variable geometry turbine (VGT) technology provides boost, contributing to the engine’s 380 Nm (280 lb-ft) of torque available from 1750 to 2750 rpm. The engine also features four valves per cylinder and an intercooler to further enhance performance. The 320d was typically paired with a six-speed manual transmission, although an eight-speed automatic transmission was also available as an option. The automatic transmission offered smoother shifts and enhanced fuel economy, but at the expense of some driver engagement.
Driving Characteristics
The 320d Gran Turismo, with its 184 horsepower and 380 Nm of torque, offered respectable, though not exhilarating, performance. Acceleration from 0 to 60 mph took around 7.6 seconds, and top speed was limited to 143 mph. The engine’s strong low-end torque made it well-suited for everyday driving and overtaking maneuvers. The manual transmission provided a more connected driving experience, while the optional automatic offered convenience. Compared to the more powerful 328i Gran Turismo or the diesel-powered 330d, the 320d felt less urgent in its acceleration. However, it excelled in fuel economy, achieving combined figures of around 48 US mpg. The Gran Turismo’s increased weight compared to the standard 3 Series sedan was noticeable, particularly during spirited driving, but the longer wheelbase contributed to a more comfortable ride.
Equipment & Trim Levels
The 320d Gran Turismo typically came well-equipped, even in base trim. Standard features included automatic climate control, a BMW iDrive infotainment system with a 6.5-inch display, power-adjustable front seats, and a leather-wrapped steering wheel. Optional extras included a larger iDrive screen, navigation, premium sound system, panoramic sunroof, and adaptive headlights. Interior upholstery was typically cloth, with leather options available at extra cost. Trim levels varied by market, but generally offered progressively more luxurious appointments and features. The Sport Line package added sporty styling cues, while the Luxury Line focused on enhanced comfort and refinement.
Chassis & Braking
The F34 Gran Turismo utilized a modified version of the 3 Series’ chassis, with a longer wheelbase and a higher ride height. The front suspension featured independent coil springs, while the rear employed an independent multi-link setup. The 320d typically came 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 suspension tuning was geared towards comfort, providing a smooth and controlled ride. Stabilizer bars were fitted front and rear to reduce body roll during cornering.
Market Reception & Comparison
The 3 Series Gran Turismo, and specifically the 320d variant, received mixed reviews from automotive critics. While praised for its spacious interior, practicality, and fuel efficiency, it was often criticized for its styling, which some found awkward. Compared to the standard 3 Series Touring, the Gran Turismo offered more rear passenger space and a larger cargo area. However, it was also more expensive and heavier. The 320d offered a compelling value proposition for buyers seeking a fuel-efficient and comfortable grand tourer, but those prioritizing sporty handling might have preferred the more powerful 328i or 330d models.
Legacy
The N47D20C engine, found in the 320d Gran Turismo, has proven to be generally reliable, although some early models were affected by timing chain issues. Proper maintenance, including regular oil changes and timely replacement of wear items, is crucial for long-term reliability. Today, used examples of the 320d Gran Turismo are relatively affordable and offer a good balance of practicality, comfort, and fuel economy. While not a particularly sought-after model among enthusiasts, it remains a viable option for buyers seeking a spacious and refined five-door vehicle.
