The BMW 518 and 518i, produced from 1990 to 1991, were the entry-level models in the E34 generation of the BMW 5 Series. These sedans were distinguished by their smaller, more fuel-efficient four-cylinder engines, making them an attractive option for drivers seeking both the renowned BMW handling and comfort at a lower price point. The 518 was powered by a 1.8-liter four-cylinder engine producing 115 horsepower, while the 518i featured a slightly more powerful 1.8-liter engine with electronic fuel injection, delivering 136 horsepower. Both engines were paired with a five-speed manual transmission, although a four-speed automatic was also available. The 518 and 518i offered a blend of everyday practicality and sporty driving characteristics. They inherited the E34's refined interior, comfortable seating, and spacious trunk, making them suitable for both daily commutes and longer journeys. Despite their smaller engines, these models still managed to deliver a satisfying driving experience thanks to BMW's precise handling and well-balanced suspension. However, their modest power output meant they weren't as quick as their six-cylinder counterparts, particularly when compared to the more powerful models in the 5 Series lineup. Nonetheless, the 518 and 518i remained popular choices for drivers seeking a more affordable entry point into the world of BMW ownership. Their reputation for reliability and fuel efficiency, coupled with their classic styling and enduring build quality, has cemented their place as desirable classic cars.
