The BMW 520i, produced from 1988 to 1991, was part of the E34 generation of the 5 Series, a mid-size executive car known for its refined driving experience and build quality. The 520i was the entry-level model within the E34 lineup, featuring a 2.0-liter naturally aspirated inline-four engine. This engine, codenamed M20, yielded a modest 129 horsepower, but its smooth and responsive nature contributed to the car's overall driving pleasure. Notably, the 520i was available with a choice of either a 5-speed manual or a 4-speed automatic transmission, further tailoring it to different driver preferences. While the 520i lacked the outright power of its larger-engined siblings, it still offered a comfortable and engaging driving experience, making it a popular choice for those seeking a well-rounded and refined BMW. The E34 generation of the 5 Series was characterized by its advanced technology for its time. The 520i featured an independent suspension system with MacPherson struts in the front and a multi-link setup in the rear, ensuring a comfortable and controlled ride. The interior was spacious and well-appointed, reflecting the premium nature of the BMW brand. Moreover, the E34 5 Series introduced new safety features, including ABS (Anti-lock Braking System) and driver and passenger airbags. The combination of these features made the 520i a well-rounded car, catering to both comfort and safety. Despite being the entry-level model, the 520i embodied the core values of the BMW brand, offering a refined driving experience, a sophisticated interior, and a dedication to safety and technology.
