The BMW 520i, produced from 1988 to 1991, was the entry-level model in the E34 generation of the 5 Series. This iteration of the 5 Series marked a significant departure from its predecessor, boasting a more aerodynamic design, improved interior comfort, and enhanced performance. The 520i was powered by a 2.0-liter inline-four engine, codenamed M20, with a single overhead camshaft (SOHC) configuration. This engine produced 128 horsepower and 124 lb-ft of torque, paired with a five-speed manual or a four-speed automatic transmission. The 520i featured a rear-wheel drive layout, providing a classic BMW driving experience. Its suspension was a sophisticated independent setup, with MacPherson struts at the front and a multi-link arrangement at the rear, resulting in a comfortable and controlled ride. Despite being the entry-level model, the 520i offered a range of standard features including power steering, power brakes, and an AM/FM cassette radio. It also featured a spacious and well-appointed interior, with comfortable seating and a user-friendly dashboard. The 520i was regarded for its overall refinement, offering a balance between performance and practicality. While it might not have the outright power of its larger-engined siblings, the 520i provided a smooth and engaging driving experience. Its fuel efficiency and relatively low cost of ownership made it a popular choice for those seeking a premium sedan with a touch of German engineering. The BMW 520i (E34) established itself as a reliable and well-rounded vehicle, earning a reputation for its durability and pleasing driving dynamics, proving its place in BMW's legacy.
