Powertrain & Engine Architecture
The heart of the 528i was the M52B28, a 2.8-liter inline-six engine. This engine was a descendant of the highly-regarded M50 and M52 families, known for their smooth power delivery and robust construction. The M52B28 featured a cast iron block with an aluminum cylinder head, dual overhead camshafts (DOHC), and four valves per cylinder. Fuel was delivered via a multi-port fuel injection system, carefully managed by the Bosch Motronic engine control unit. The engine produced 193 horsepower at 5500 rpm and 280 Nm (206.52 lb-ft) of torque at 3500 rpm. Paired with this engine was a ZF 5HP18 5-speed automatic transmission, chosen for its smoothness and reliability. This transmission offered a balance between fuel efficiency and responsive shifting, although it wasn’t as sporty as the available 5-speed manual.
Driving Characteristics
The 528i automatic offered a comfortable and refined driving experience. While not as overtly sporty as the manual transmission version or the 540i, the automatic provided effortless cruising and adequate acceleration. The 5-speed automatic was well-matched to the engine’s torque curve, providing smooth shifts and minimizing noticeable lag. Acceleration from 0 to 60 mph took approximately 8.4 seconds, and the car could reach a top speed of 146 mph. Compared to the 523i, the 528i offered a noticeable increase in power and responsiveness. However, the 540i, with its larger 4.4-liter V8, provided significantly more performance, but at the cost of increased fuel consumption.
Equipment & Trim Levels
The 528i came standard with a respectable array of features, including power windows, power locks, a sunroof, and air conditioning. Interior upholstery was typically cloth, although leather was available as an option. The dashboard featured a classic BMW layout with clear, easy-to-read gauges. Optional extras included heated front seats, a premium sound system, navigation, and automatic climate control. The 528i often sat in a sweet spot in the lineup, offering a good balance of features and price. It was a popular choice for buyers who wanted a luxurious and capable sedan without the higher price tag of the 540i.
Chassis & Braking
The E39 5 Series boasted a sophisticated chassis design. The 528i utilized a MacPherson strut front suspension and a multi-link rear suspension, providing a comfortable ride and precise handling. Brakes were ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) was standard. The suspension tuning was geared towards comfort, but still provided a secure and planted feel on the road. The steering was hydraulic power steering, offering a good balance of assistance and feedback.
Market Reception & Comparison
The E39 528i was generally well-received by automotive critics. It was praised for its refined engine, comfortable ride, and well-appointed interior. The automatic transmission was considered a good match for the engine, although some reviewers preferred the engagement of the manual gearbox. Fuel economy was reasonable for a car of its size and performance, averaging around 27.4 mpg on the highway. Compared to competitors like the Mercedes-Benz E-Class and the Audi A6, the 528i was often seen as the more driver-focused option. Reliability was generally good, although like all BMWs of this era, preventative maintenance was crucial.
Legacy
The E39 528i, particularly the automatic variant, has proven to be a durable and reliable vehicle. Today, well-maintained examples are sought after by enthusiasts. The M52B28 engine is known for its longevity and relatively simple maintenance requirements. While age-related issues such as cooling system components and suspension bushings are common, parts availability remains good. The 528i automatic represents a compelling value in the used car market, offering a taste of BMW luxury and performance at an affordable price. It remains a popular choice for those seeking a classic European sedan that is both enjoyable to drive and relatively easy to maintain.
