The BMW 518, produced from 1981 to 1985, was a compact executive sedan that marked a significant shift in BMW's approach to its mid-size offerings. This generation, internally known as the E12, was the last iteration of the original 5 Series platform and represented a departure from the sporty, driver-focused ethos that would become synonymous with the model line. The 518 focused on affordability and fuel efficiency, employing a smaller, less powerful engine than its siblings. This was a strategic response to the rising fuel costs and tightening emissions regulations of the early 1980s, appealing to a wider market that valued practicality and economy over outright performance. While it lacked the performance of its larger-engined counterparts, the 518 still possessed the characteristic BMW handling and driving dynamics, offering a comfortable and refined ride. The 518 was powered by a 1.8-liter four-cylinder engine, producing a modest 90 horsepower. While not a performance powerhouse, this engine provided adequate acceleration and fuel economy, delivering a respectable 28 miles per gallon on the combined cycle. Despite its focus on practicality, the 518 retained the elegant styling and sophisticated interior that defined the E12 generation. It featured a well-appointed cabin with comfortable seats and a functional dashboard. The 518's suspension, known for its responsive handling and well-balanced ride, provided a comfortable driving experience despite the car's relatively small size. The 518, while not as iconic as its more powerful siblings, played a crucial role in the BMW 5 Series' success. This entry-level model expanded the appeal of the model line, attracting a wider range of buyers who valued efficiency and affordability without compromising on the classic BMW driving experience.
