2020 BMW 840i

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2020 840i.

Transmission Automatic (S8)

The 2020 BMW 840i is anchored by its S8 automatic transmission and EPA fuel economy ratings of 22 mpg city, 29 mpg highway, and 24 mpg combined, figures that frame it as an efficiency-minded entry within the 8 Series lineup. For researchers assembling a reference profile, these documented specifications—transmission type and fuel economy—constitute the core quantitative identity of the 2020 840i as provided in its overview. Within the 840i's model history, this year's available data establishes a clear powertrain and efficiency baseline, though the overview itself does not extend to reliability assessments that would place 2020 in a broader long-term context.
