Design, development and variant notes
The M10 uses an iron block and an aluminium cross-flow head with two valves per cylinder, a chain-driven camshaft and a forged crankshaft. It was originally designed to grow from 1.5 to 2.0 litres; the family was introduced in the New Class.
Early family designations included M115; BMW later used the M10 name for the family. The M12 racing engine used an M10-derived block. The individual Wikipedia article dates production from 1962 to 1988, which differs from its broader engine-list entry.

Additional technical and variant notes
M115: 1,499 cc, 82 × 71 mm, and 55–60 kW; the source lists 8.0:1 and 8.8:1 compression ratios for different outputs. M116: 1,573 cc, 84 × 71 mm, and 63–77 kW; the 1600 ti used a higher compression ratio and twin carburettors.
The M10B18 is listed at 1,766 cc with an 89 × 71 mm bore and stroke. The 1,990 cc M05 uses 89 × 80 mm; M15 is the mechanically injected tii variant. The M31 turbo version is listed at 125 kW and 6.9:1 compression.

The article lists a Solex 38 PDSI carburettor for the 1,499 cc M115. It also reports up to 1,030 kW for the M10-block-based M12 Formula One engine in qualifying trim, but marks that racing-power claim as needing a citation.
