Powertrain & Engine Architecture
The heart of the 328i Gran Turismo is BMW’s N20B20A 2.0-liter turbocharged inline-four engine. This engine, part of BMW’s modular engine family, utilizes direct fuel injection, a twin-scroll turbocharger, and variable valve timing (VANOS) and valve lift (Valvetronic) technologies. These features work in concert to deliver a broad torque curve and responsive performance. The N20 engine is known for its efficiency and relatively smooth operation. The Steptronic 8-speed automatic transmission is a crucial component, offering quick and seamless gear changes. It features a torque converter and allows for both fully automatic operation and manual gear selection via steering wheel-mounted paddles or the gear selector. The transmission’s programming is tuned for a balance of comfort and performance, prioritizing smooth shifts during normal driving and quicker downshifts when in Sport mode.
Driving Characteristics
The 328i Gran Turismo with the Steptronic transmission delivers a comfortable and refined driving experience. While not as overtly sporty as the 335i models, the 245 horsepower and 350 lb-ft of torque provide ample power for everyday driving and highway passing. The 8-speed automatic transmission contributes to good fuel economy, and the engine’s turbocharger provides a noticeable boost in acceleration. Compared to the 6-speed manual transmission available on other 328i models, the Steptronic offers smoother shifts and easier operation, particularly in stop-and-go traffic. However, some enthusiasts may find the automatic transmission less engaging than the manual. The Gran Turismo’s longer wheelbase and increased weight compared to the standard 3 Series sedan result in slightly less agile handling, but the suspension is well-tuned to provide a comfortable ride.
Equipment & Trim Levels
The 328i Gran Turismo came standard with a generous array of features, including leatherette upholstery, power-adjustable front seats, a BMW iDrive infotainment system with a 6.5-inch display, automatic climate control, and a suite of safety features like ABS, stability control, and multiple airbags. Optional extras included leather upholstery, a premium sound system, navigation, a panoramic sunroof, and various driver-assistance systems such as lane departure warning and adaptive cruise control. Trim levels were relatively simple, with most options being added individually. The Gran Turismo’s interior design emphasized spaciousness and comfort, with a focus on high-quality materials and a user-friendly layout.
Chassis & Braking
The F34 328i Gran Turismo utilizes a MacPherson strut front suspension and a multi-link rear suspension. The suspension is tuned for a balance of comfort and handling, providing a relatively smooth ride while maintaining good body control. The braking system consists of ventilated disc brakes on all four wheels, providing ample stopping power. ABS (Anti-lock Braking System) is standard, along with electronic brake-force distribution and brake assist. The steering is electrically assisted, offering precise and responsive control. The Gran Turismo’s chassis is reinforced compared to the standard 3 Series to accommodate the larger body and increased weight.
Market Reception & Comparison
The BMW 3 Series Gran Turismo received mixed reviews from automotive critics. While praised for its spaciousness, practicality, and comfortable ride, it was often criticized for its styling, which some found awkward. The 328i variant was generally well-regarded for its balance of performance and fuel efficiency. Compared to the 335i models, the 328i offered a more affordable entry point into the Gran Turismo lineup, while still providing a respectable level of performance. In terms of fuel economy, the 328i outperformed the 335i, making it a more attractive option for buyers prioritizing efficiency. Reliability reports suggest that the N20 engine is generally reliable, but some owners have reported issues with the turbocharger and fuel injectors.
Legacy
The BMW 3 Series Gran Turismo, while not a mainstream success, offered a unique proposition in the premium compact segment. The 328i Steptronic variant remains a relatively common sight on the used car market, offering a comfortable and practical option for buyers seeking a spacious and well-equipped vehicle. The N20 engine’s reputation for reliability and fuel efficiency contributes to the 328i’s continued appeal. However, potential buyers should be aware of the potential for turbocharger and fuel injector issues and ensure that the vehicle has been properly maintained. The F34 Gran Turismo represents an interesting chapter in BMW’s history, showcasing the brand’s willingness to experiment with new body styles and technologies.
