The 1983 model year of the BMW E28 marked several significant developments and the introduction of new models, further enhancing the lineup’s versatility and appeal. Building on the innovative design, technology, and performance attributes of the initial E28 model, the 1983 iteration introduced the brand’s first diesel car and the M535i performance model.
Design
The exterior design of the 1983 E28 was much the same as the earlier models, preserving the streamlined body lines, twin-kidney grille, and the quad round headlights, a design language that encapsulated the essence of BMW at the time. Inside, the angled center console catered to the driver, with ergonomic placement of controls and instruments. High-quality materials and improved interior space contributed to enhanced comfort and luxury.
Specifications
In 1983, BMW expanded the E28 lineup by introducing new models:
- The 524td, BMW’s first diesel passenger car, debuted. It came with a 2.4-liter M21 inline-six turbo-diesel engine, producing 115 horsepower. This model was especially noted for being the world’s first passenger car equipped with an electronically controlled injection pump.
- The M535i, a performance-oriented model, also made its entrance. Powered by the 3.5-liter M30B34 inline-six engine, the M535i produced 218 horsepower and 224 lb-ft of torque. It was paired with either a five-speed manual or a four-speed automatic transmission. The M535i featured several performance enhancements, such as a limited-slip differential, larger brakes, and sport-tuned suspension. Moreover, it had distinctive styling elements like front and rear spoilers, sport seats, and bespoke trim.
The existing lineup, including the four-cylinder 518 and the six-cylinder 520i, 525i, and 528i, continued alongside the newly introduced models.
Performance and Reception
The M535i was the star of the 1983 E28 lineup, offering increased performance and sportier handling compared to other models. It was lauded for its blend of luxury, practicality, and performance – traits that would become defining characteristics of the M5, introduced later in the E28’s lifecycle.
The 524td, on the other hand, appealed to customers seeking fuel efficiency and long-distance cruising capability. Despite being a diesel, it offered respectable performance and was commended for its smooth operation.
Like its predecessors, the 1983 E28 was highly praised for its build quality, innovative technologies (like the optional ABS and “check control” system), and engaging driving dynamics. Its combination of performance and comfort solidified the 5 Series’ place in the executive car segment.
