The E28, launched in 1981, was the first generation to adopt a more aerodynamic design, with sharp edges and a distinctive grille. It offered a range of powerful engines, including the iconic M5, which boasted a 3.5-liter inline-six engine capable of reaching 0-60 mph in just six seconds. The E28 was praised for its handling, comfort, and overall refinement, solidifying BMW's position as a leader in the executive car segment.

It featured a more rounded, aerodynamic design with a longer wheelbase for improved passenger space. Engine options were further expanded, including the introduction of a V8 engine in the 540i model. The E34 was a technological marvel, featuring innovations like anti-lock brakes, traction control, and a driver's airbag as standard equipment. Its reputation for driving pleasure was further enhanced by the introduction of the legendary M5, now powered by a 3.8-liter inline-six producing over 300 horsepower. The E34 5 Series remained a benchmark for luxury and performance, leaving an enduring legacy in the automotive world.
