E64 platform
2009 BMW 650I E64
Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2009 650I.
Transmission Automatic (S6)
The 2009 BMW 650I rides on the E64 platform and pairs its automatic (S6) transmission with an engine requiring 8.5 quarts of oil — specified at 15W-40, 10W-40, or 10W-30 API SJ viscosity — while returning EPA figures of 15 city, 23 highway, and 18 combined mpg. Reliability data places this model year on the quieter end of the 650I's complaint spectrum, with just 9 total owner complaints (centered on the Fuel System, Gasoline category) and 3 recalls, figures that look modest next to the model's later peak of 22 complaints in 2012 before tapering to just 3 by 2015. For a researcher, that trajectory suggests the 2009 sits in a relatively stable early run of the generation, before complaint volume climbed in subsequent years — making it a comparatively well-behaved entry point in the 650I's documented reliability history.
