E66 platform
2003 BMW 760LI
Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2003 760LI.
Transmission Automatic (S6)
The 2003 BMW 760Li operates as the long-wheelbase flagship of the E66 platform, routing power through an automatic (S6) transmission while returning EPA fuel economy figures of 13 city, 16 combined, and 21 highway mpg. Maintaining this powertrain requires a substantial 9.0 quarts of engine oil, specifying 15W-40, 10W-40, or 10W-30 API SJ viscosity to ensure proper lubrication under demanding thermal loads. From a reliability standpoint, the model's complaint history tracked between 2011 and 2015 is remarkably flat, with the highest and lowest year both registering just three complaints in 2011. This singular, low-volume data point indicates that the 2003 model sits at a surprisingly stable position in the chassis' history, presenting researchers with a variant largely free of the chronic failures that often plague complex luxury sedans.
