Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 M240i.
The 2021 BMW M240i is documented with a 6.55‑quart oil capacity and uses 0W‑20 viscosity oil. Its EPA fuel‑economy rating is 21 city, 30 highway and 24 combined miles per gallon, and it is equipped with an Automatic (S8) transmission. The model falls within a reliability period that spans 2017 through 2025, during which complaint counts have declined from a high of three in 2017 to a low of one in 2025. This downward trend indicates that the 2021 iteration benefits from the later improvements recorded in the model’s history.
