Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 M8.
The 2023 BMW M8 pairs its high-performance positioning with an eight-speed automatic (S8) transmission and EPA-estimated fuel economy of 15 mpg city, 22 mpg highway, and 17 mpg combined. Available complaint data for the model line spans only the 2019 through 2021 model years, a period in which 2020 recorded exactly five complaints—representing both the highest and lowest complaint counts within that specific timeframe. Consequently, the 2023 model year sits outside that documented reliability window, meaning researchers must evaluate its standing without the benefit of complaint statistics that specifically cover this production year.
