The BMW 535i (E28) Automatic, produced between 1984 and 1987, represented a significant step forward in BMW’s mid-size luxury sedan offerings. Positioned as a premium variant within the E28 5 Series lineup, it bridged the gap between the more economical 528i and the high-performance M5. This model combined a potent inline-six engine with a three-speed automatic transmission, aiming to deliver a blend of performance and comfort for discerning drivers. The E28 generation itself was a pivotal model for BMW, establishing many of the design and engineering hallmarks that would define the 5 Series for decades to come.

Powertrain & Engine Architecture
The heart of the 535i Automatic was the M30B34 engine, a 3.4-liter inline-six. This engine was a refinement of the M30 family, known for its smoothness and durability. The B34 featured a cast iron block and an aluminum cylinder head, employing a single overhead camshaft (SOHC) design with two valves per cylinder. Fuel delivery was handled by Bosch Motronic multi-port fuel injection, a significant advancement over earlier carbureted BMW engines. This system allowed for precise fuel metering and improved emissions control. The engine’s 9:1 compression ratio contributed to its strong torque output. Paired with the M30B34 was a three-speed automatic transmission (typically the ZF 3HP22), chosen for its smoothness and reliability. While not offering the sporting engagement of a manual gearbox, the automatic provided a more relaxed driving experience, appealing to a broader customer base.
Driving Characteristics
The 535i Automatic offered a distinctly different driving experience compared to its manual transmission counterparts or the higher-performance M5. The automatic transmission, while smooth, did introduce some power loss. Acceleration from 0 to 60 mph was typically in the low-to-mid 8-second range, respectable for the era but slower than the manual 535i. The three-speed automatic’s gear ratios were optimized for cruising comfort rather than outright acceleration. The torque converter provided ample low-end grunt, making everyday driving effortless. However, downshifts could be somewhat sluggish, and the transmission lacked the responsiveness of a modern automatic. The car’s weight distribution, typical of BMW’s longitudinal engine layout, contributed to balanced handling, but the automatic transmission added weight compared to the manual versions.
Equipment & Trim Levels
The 535i Automatic was generally well-equipped for its time. Standard features included power windows, power locks, a sunroof, and air conditioning. Interior upholstery was typically cloth, with leather options available as an upgrade. The dashboard layout was functional and driver-focused, with clear analog gauges. Optional extras included a premium sound system, heated seats, and a limited-slip differential. The trim level was generally considered a step above the base 528i, offering a more luxurious and refined interior. The automatic transmission itself was often considered an option that appealed to buyers prioritizing comfort and convenience over outright performance.
Chassis & Braking
The E28 5 Series featured a robust chassis with independent suspension at all four wheels. The front suspension utilized MacPherson struts, while the rear employed a semi-trailing arm design. Stabilizer bars were fitted front and rear to reduce body roll. The 535i Automatic came standard with disc brakes on all four wheels, providing ample stopping power. The braking system was not power-assisted, requiring a firm pedal effort. Suspension tuning was geared towards a balance of comfort and handling, offering a compliant ride without sacrificing cornering stability. The rear brakes were solid discs, a common setup for the time, and adequate for the car’s weight and performance.
Market Reception & Comparison
The 535i Automatic was generally well-received by automotive critics. It was praised for its smooth engine, comfortable ride, and well-appointed interior. However, some reviewers noted that the automatic transmission detracted from the car’s overall sporting character. Compared to the manual 535i, the automatic version offered slightly lower fuel economy and slower acceleration. Against competitors like the Mercedes-Benz 190E and the Audi 100, the 535i Automatic offered a more engaging driving experience and a more luxurious interior. Reliability was generally good, although the automatic transmission could require occasional servicing.
Legacy
The BMW 535i (E28) Automatic holds a respected place in BMW history. The M30B34 engine is renowned for its durability and is still sought after by enthusiasts today. While the three-speed automatic transmission is now considered outdated, it remains a reliable unit when properly maintained. The E28 5 Series, as a whole, is considered a classic BMW, and well-maintained examples command a premium in the used car market. The 535i Automatic, while not as highly prized as the manual version or the M5, offers a unique blend of luxury, performance, and comfort that continues to appeal to collectors and enthusiasts alike. Its enduring appeal is a testament to BMW’s engineering prowess and the timeless design of the E28 generation.
