E66 platform
2007 BMW 750LI
Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2007 750LI.
Transmission Automatic (S6)
As a long-wheelbase flagship built on BMW's E66 platform, the 2007 750Li pairs an 8.5-quart oil capacity — specified at 15W-40, 10W-40, or 10W-30 API SJ — with the S6 six-speed automatic, the powertrain combination that defined its era. EPA fuel-economy ratings of 15 mpg city, 23 mpg highway, and 18 mpg combined quantify exactly how much that S6 was being asked to propel, framing a car whose mechanical sophistication also made it a long-term owner-report data point. NHTSA complaint history from 2012 through 2016 traces a sharp downward slope — 26 complaints in 2012 collapsing to a single complaint by 2016 — suggesting that any cluster of issues surfaced early in the reporting window and largely faded from owner submissions by the end of it.
