Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 M8 Gran Coupe.
The 2023 BMW M8 Gran Coupe channels output through an eight-speed automatic transmission, an arrangement that returns EPA fuel economy estimates of 15 mpg in the city, 22 mpg on the highway, and 17 mpg combined. These documented efficiency figures give researchers a consistent technical baseline for cataloging the model year, even though the supplied reference data is limited to transmission type and EPA testing results. A complete placement of the 2023 model year within the M8 Gran Coupe's reliability history would therefore require additional sourcing on service records, warranty claims, and long-term durability beyond the material provided here.
