BMW 1 Series M Coupe

The story

The 1M is what a small team with a thin budget can do with the right leftovers. The chassis was the E82 coupe, rear-drive only because BMW had stubbornly refused to follow its rivals to front-wheel drive. The engine was the N54 twin-turbo six from the 135i, not an M-built unit at all. From the V8 M3 came aluminum suspension, big brakes, a quicker steering rack and a mechanical limited-slip differential able to lock completely, all tucked under flared arches over a track 55 mm wider than the donor car. A 6-speed manual was the only gearbox offered.

Off boost it is calm, almost lazy. Catch the turbos mid-corner, though, and the short wheelbase lets the tail swing wide with real appetite. BMW sold it as heir to the original M3, and fans read it as an apology for the heavier V8 car, even though the 2 shared showrooms for 18 months. Whatever the motive, buyers got it immediately: BMW planned 2,700 and built 6,309. The M2 that followed beat it on every stopwatch, but the 1M had already proved the formula.
