The BMW 3 Series Gran Turismo (F34) LCI, specifically the 318d variant with the Steptronic automatic transmission, was produced from 2016 to 2020. This model represents a facelift of the original F34 Gran Turismo, introduced in 2013, aiming to blend the practicality of a touring wagon with the sleek styling of a coupe. Positioned as a mid-range offering within the Gran Turismo lineup, the 318d Steptronic provided a balance between fuel efficiency, comfortable cruising, and BMW’s signature driving dynamics. It served as an alternative to the more performance-focused 320i/330i models and the more expensive 335i/340i variants, appealing to buyers prioritizing economy and refinement.

Powertrain & Engine Architecture
The 318d Gran Turismo LCI utilizes BMW’s B47D20A 2.0-liter inline-four diesel engine. This engine is a member of the modular BMW engine family, known for its efficiency and refinement. The B47 features a single turbocharger with variable geometry turbine (VGT) technology, an intercooler, and a sophisticated common-rail direct fuel injection system operating at pressures up to 2,000 bar. The engine’s cylinder head incorporates four valves per cylinder, contributing to improved breathing and power delivery. The Steptronic 8-speed automatic transmission is a torque-converter type, offering smooth and efficient gear changes. It features adaptive shift programs that adjust to the driver’s style and road conditions. The transmission is longitudinally mounted, driving the rear wheels.
Driving Characteristics
The 318d Steptronic Gran Turismo delivers a comfortable and refined driving experience. While not overtly sporty, the 150 horsepower and 320 Nm (236 lb-ft) of torque provide adequate performance for everyday driving and long-distance cruising. Acceleration from 0-60 mph takes approximately 8.7 seconds, and the car reaches a top speed of 130 mph. The Steptronic transmission contributes to smooth acceleration and minimizes gear hunting. Compared to the more powerful 320d or 330d variants, the 318d feels less urgent in its acceleration, but its lower weight and efficient engine contribute to better fuel economy. The gear ratios are tuned for fuel efficiency, with taller gearing in higher gears for relaxed highway cruising.
Equipment & Trim Levels
The 318d Steptronic Gran Turismo typically came standard with features such as automatic climate control, power windows, power mirrors, a multi-function steering wheel, and a BMW iDrive infotainment system with a 6.5-inch display screen. Standard safety equipment included ABS, stability control, and multiple airbags. Optional extras included leather upholstery, a larger iDrive screen with navigation, a premium sound system, parking sensors, and adaptive cruise control. Trim levels varied by market, but generally offered packages that bundled popular options together.
Chassis & Braking
The F34 Gran Turismo features a double-wishbone front suspension and an independent multi-link rear suspension, providing a comfortable ride and good handling characteristics. The 318d variant typically came equipped with ventilated disc brakes on all four wheels. The braking system is assisted by ABS and electronic brakeforce distribution. The suspension is tuned for comfort, with a focus on absorbing bumps and providing a stable ride. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The 318d Steptronic Gran Turismo was generally well-received by automotive critics as a practical and efficient grand tourer. It was praised for its comfortable ride, spacious interior, and good fuel economy. However, some critics noted that the 318d lacked the outright performance of its more powerful siblings. Compared to the 320d, the 318d offered a lower price point but sacrificed some performance. The 318d’s fuel economy was comparable to that of the 320d, but its lower power output made it a more appealing option for drivers prioritizing efficiency over speed.
Legacy
The BMW 3 Series Gran Turismo (F34) was discontinued in 2020, replaced by other models in BMW’s lineup. The B47 engine has proven to be a reliable and durable powerplant, with many examples exceeding high mileage without major issues. The Steptronic 8-speed automatic transmission is also known for its reliability. On the used car market, the 318d Steptronic Gran Turismo represents a good value proposition for buyers seeking a comfortable, spacious, and fuel-efficient grand tourer. However, potential buyers should be aware of the potential for diesel particulate filter (DPF) issues, particularly on vehicles that have primarily been used for short trips.
