The BMW M70 V12 engine, a masterpiece of automotive engineering, was a 6.0-liter, naturally aspirated, 60-degree V12 gasoline engine that powered some of BMW's most prestigious and powerful cars. Introduced in 1986 with the E32 7 Series, the M70 quickly gained a reputation for its smooth, powerful, and refined performance. It featured a lightweight aluminum block and cylinder heads, contributing to its remarkable power-to-weight ratio.
