The BMW M1: A V8/V10 Near Miss and the Triumph of the M88 Straight-Six

The BMW M1 is a seminal vehicle in automotive history, revered for its sleek design, status as BMW M’s inaugural supercar, and the legendary M88 engine nestled in its rear. However, the story behind the M1’s engine selection is a fascinating one, revealing that BMW had initially contemplated alternative powertrains.

In a recent discussion featuring Tom Pluckinsky, Head of BMW Classic USA, and Steve Saxty, author of the acclaimed “BMW by Design” series, insights were shared on the M1’s development process. Surprisingly, BMW had entertained the idea of equipping the M1 with a V8 or V10 engine before ultimately opting for the iconic M88 inline-six that defined the car’s performance.

The Significance of the BMW M1

The BMW M1’s development was driven by a focus on racing, with the road car serving as a means to meet homologation requirements. Unlike past experiences with the 3.0 CSL, BMW adopted a new strategy with the M1, prioritizing the race car’s design and then adapting it for street use.

Central to this approach was the selection of the powertrain. BMW faced a tight deadline set by their chassis development partner, prompting a swift decision on the engine configuration. While initial designs hinted at a different engine layout, the choice of the M88 inline-six led to innovative design solutions, such as cleverly integrated side vents to mask the engine’s height.

The Evolution of the M88 Engine

The M88 engine, with its innovative features like dual overhead camshafts and dry-sump lubrication, not only propelled the M1 to supercar status but also left a lasting mark on BMW’s performance lineup. Its inclusion in the iconic E28 M5 sedan showcased the engine’s versatility and performance capabilities, setting a benchmark for future BMW M models.

Reflecting on the M1’s development journey, the decision to adopt the M88 engine stands as a pivotal moment in automotive history. While other engine options were considered, the M1’s legacy as a race-bred supercar owes much to the distinctive character and engineering excellence of the M88 inline-six.
