Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2007 X3 3.0SI.
Body SUVTransmission Automatic (S6)
The 2007 BMW X3 3.0si is an SUV built on BMW's E83 platform, paired exclusively with a six-speed automatic (S6) transmission and serviced with 6.9 quarts of oil in 15W-40, 10W-40, or 10W-30 API SJ grades. EPA fuel economy of 17 mpg city, 24 mpg highway, and 20 mpg combined reflects a powertrain calibrated for utility over efficiency, and the 3.0si trim designation identifies the specific engine variant offered that year. The model year is defined less by these mechanical specifications, however, than by its reliability profile: 373 owner complaints and six recalls have been logged against it, with the airbag system standing out as the most frequently reported problem area — a pattern of safety-system issues that researchers should treat as a central consideration when evaluating this entry.
