Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2009 550I.
Transmission Automatic (S6)
The 2009 BMW 550i, built on the E60 platform, is a performance-oriented executive sedan that pairs a six-speed automatic transmission with a substantial 8.5-quart oil capacity, using viscosities like 15W-40 or 10W-40, and returns EPA fuel economy estimates of 15 mpg city and 23 mpg highway. Within the model’s complaint history spanning 2011 to 2015, this 2009 model year predates the peak of 172 complaints recorded in 2011, suggesting it sits in a comparatively more favorable position relative to the reliability challenges that surfaced later in the generation.
