Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1994 850CI.
The 1994 BMW 850CI, built on the E31 platform, is equipped with an engine that requires 7.9 qt of oil meeting API SJ and is available in viscosities of 15W‑40, 10W‑40 or 10W‑30. Its EPA fuel economy is recorded as 11/17/13 mpg and it is paired with an Automatic 4‑spd transmission. Across the 1991‑1997 production span the model logged only a single complaint in its peak year of 1992, indicating a consistently low level of reported problems, and the 1994 model year continues that pattern of reliability. Consequently, researchers can view the 1994 850CI as a vehicle whose operational data reflect a stable, low‑complaint history within its generation.
