2011 BMW 1 Series

The 1-of-1 BMW 1M CSL (engine-swapped with an M3 V8 B80) is a bespoke performance machine that fuses the raw agility of the BMW 1M with the ferocious power of BMW’s legendary naturally aspirated V8. With its custom CSL-inspired lightweight construction, rear-wheel drive, and high-revving M3 V8 paired to a performance automatic/manual transmission, it offers a truly unique driving experience that blends exclusivity, engineering artistry, and motorsport heritage.

This 1-of-1 BMW 1M CSL V8 swap sits in the bespoke performance car segment, with no direct production rivals. It draws inspiration from BMW’s motorsport icons like the E46 M3 CSL and E92 M3 GTS, while competing in spirit with custom builds, but there is nothing else like this one-off build.
