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 E64, built on the E64 platform, is powered by an engine that holds 8.5 qt of oil and meets API SJ specifications with viscosities of 15W‑40, 10W‑40 or 10W‑30. It is mated to an automatic S6 transmission and achieves EPA‑rated fuel economy of 15 mpg city, 23 mpg highway and 18 mpg combined. Reliability records show only a single owner complaint, centered on the engine, and the model carries just one recall, while later model‑year complaint data (2012‑2015) peak at 22 complaints in 2012 before dropping to three in 2015, indicating that the 2006 version predates the higher‑complaint periods and generally reflects a low‑issue profile.
