2012-2015 BMW 3 Series Sedan (F30) 335i (306 Hp) xDrive Steptronic

The BMW 3 Series Sedan (F30) 335i xDrive Steptronic, produced from July 2012 to June 2015, represents a compelling blend of performance and all-weather capability within the sixth generation (F30) of BMW’s iconic 3 Series. Positioned as a mid-to-high range offering, the 335i xDrive catered to buyers seeking a significant step up in power and refinement compared to the base 328i models, while offering a more accessible entry point into the performance-oriented world of the 3 Series than the flagship M3. This variant combined BMW’s renowned inline-six engine with their xDrive all-wheel-drive system and an eight-speed Steptronic automatic transmission, creating a sophisticated and capable grand touring sedan.

Technical Specifications

Powertrain & Engine Architecture

At the heart of the 335i xDrive lies the N55B30A, a 3.0-liter inline-six cylinder engine. This engine is a direct descendant of BMW’s long-standing tradition of smooth and powerful six-cylinder engines, but incorporates significant advancements in technology. The N55 features direct fuel injection, ensuring precise fuel delivery for optimal combustion and efficiency. It also utilizes BMW’s VALVETRONIC variable valve timing and lift system, along with Double-VANOS variable valve timing on both the intake and exhaust camshafts. These technologies work in concert to optimize engine breathing across the rev range, resulting in a broad torque curve and responsive performance. The engine is turbocharged by a twin-scroll turbocharger, which minimizes turbo lag and enhances low-end torque. The eight-speed Steptronic automatic transmission is a key component of the powertrain, offering smooth and quick shifts. It features adaptive shift programs that adjust to the driver’s style and driving conditions.

Driving Characteristics

The 335i xDrive delivers a refined and engaging driving experience. The combination of the potent inline-six engine, the quick-shifting Steptronic transmission, and the xDrive all-wheel-drive system results in confident acceleration and handling in all weather conditions. While not as overtly sporty as the manual transmission-equipped 335i, the automatic provides a seamless power delivery and allows the driver to focus on enjoying the ride. The xDrive system intelligently distributes torque between the front and rear axles, maximizing traction and stability. The 0-60 mph time of around 4.8 seconds is indicative of the car’s performance capabilities. Compared to the 328i, the 335i offers a substantial increase in power and torque, resulting in noticeably quicker acceleration and more effortless cruising.

Equipment & Trim Levels

The 335i xDrive typically came well-equipped as standard. Common features included leather upholstery, power-adjustable front seats with memory function, a premium sound system, automatic climate control, and BMW’s iDrive infotainment system with a central display screen. Optional extras were plentiful, including a navigation system, a head-up display, adaptive cruise control, a panoramic sunroof, and various driver assistance systems. Interior trim options ranged from wood veneers to aluminum accents, allowing buyers to personalize the cabin to their taste.

Chassis & Braking

The F30 3 Series utilizes a sophisticated chassis design. The front suspension features MacPherson struts with a transverse stabilizer bar, while the rear suspension employs a multi-link setup, also with a stabilizer bar. This configuration provides a good balance between ride comfort and handling precision. The 335i xDrive was equipped with ventilated disc brakes on all four wheels, providing ample stopping power. The ABS (Anti-lock Braking System) and stability control systems further enhance safety and control.

Market Reception & Comparison

The 335i xDrive was generally well-received by automotive critics. It was praised for its powerful engine, refined ride, and all-weather capability. Some reviewers noted that the automatic transmission, while smooth, didn’t offer the same level of engagement as the manual gearbox. Compared to the 328i, the 335i offered a significant performance upgrade, but at a higher price point. The 335i also provided a more accessible entry point into the performance-oriented world of the 3 Series compared to the M3. Fuel economy was respectable for a performance sedan, averaging around 30.9 US mpg in combined driving.

Legacy

The N55 engine, found in the 335i xDrive, has proven to be a relatively reliable powerplant, although preventative maintenance is crucial. Common issues include oil leaks, fuel injector problems, and occasional cooling system failures. The eight-speed Steptronic transmission is also generally reliable, but requires regular fluid changes. Today, the F30 335i xDrive represents a compelling value on the used car market, offering a blend of performance, luxury, and all-weather capability at a reasonable price. It remains a popular choice for enthusiasts seeking a well-rounded and engaging driving experience.
