The BMW E30 M3, a legendary homologation special, was born out of the Group A touring car racing regulations of the late 1980s. To compete in this fiercely competitive class, BMW needed a road-going version of its race car, leading to the development of the E30 M3. Released in 1986, the E30 M3 quickly gained a reputation for its exceptional performance and handling, becoming a benchmark for sports cars of its era. The 1991 model year saw subtle updates to the E30 M3, including revised suspension and a slightly larger rear spoiler. Power came from a 2.3-liter naturally aspirated inline-four engine, producing 215 horsepower and 190 lb-ft of torque. This engine, paired with a five-speed manual transmission, propelled the E30 M3 from 0 to 60 mph in just 6.5 seconds. The E30 M3's appeal transcended its impressive performance figures. It possessed a unique blend of driver engagement, agility, and practicality that made it equally enjoyable for daily driving and track days. Its lightweight construction, featuring a mix of steel and aluminum, contributed to its agile handling and responsiveness. The E30 M3's iconic design, with its flared wheel arches, distinctive front bumper, and rear spoiler, was instantly recognizable and remains a classic even today. Unfortunately, production of the E30 M3 ceased in 1991, leaving a lasting legacy as one of the most iconic and sought-after sports cars of all time. The E30 M3's enduring popularity makes finding repair and maintenance information crucial for its passionate owners. The 1991 BMW E30 M3 Workshop Repair Service Manual provides an invaluable resource for anyone looking to undertake repair or maintenance work on their cherished E30 M3.
