Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2006 650I.
Transmission Automatic (S6)
The 2006 BMW 650I, built on the E64 platform, is a luxury sedan powered by a high‑performance engine that requires 8.5 qt of oil—typically 15W‑40, 10W‑40, or 10W‑30 API SJ—and is paired with an automatic S6 transmission; its EPA rating is 15 mpg city, 23 mpg highway, and 18 mpg combined. In the broader reliability window of 2012‑2015, the 650I’s 2006 model sits toward the lower end of complaint counts, with the 2015 year recording only three complaints versus the 22 of 2012, indicating a relatively stable mechanical foundation for that era.
