The 518i, powered by a 1.8-liter four-cylinder engine, offered a compelling blend of fuel efficiency and everyday practicality while retaining the hallmark BMW driving dynamics. The engine, codenamed M40, generated a respectable 113 horsepower, allowing the 518i to reach a top speed of 185 km/h (115 mph) while achieving a fuel economy figure of around 7.5 liters per 100 kilometers (37 mpg).

The dashboard design was both functional and elegant, featuring a clear instrument cluster and easy-to-use controls. The spacious cabin provided ample room for both passengers and luggage, with the touring version offering even greater cargo capacity. The 518i E34 came standard with a comprehensive list of features including power windows, power door locks, air conditioning, and an AM/FM radio cassette player. Optional extras included leather upholstery, a sunroof, and a premium sound system.
