The 2025 BMW 840i Coupe is the six-cylinder base model of the G15 8 Series, BMW's two-door flagship grand tourer built on the CLAR platform. Its single-turbocharged B58 3.0-liter inline-six produces 335 hp and drives the rear wheels through a ZF 8-speed Steptronic automatic, with BMW quoting a 0-100 km/h (0-62 mph) time of 5.3 seconds for the rear-drive coupe. Below the V8-powered M850i xDrive and the M8, the 840i prioritizes long-legged refinement and efficiency, earning a 24 mpg EPA combined rating. It is the smooth, accessible foundation of a low-slung 2+2 lineup that also spans Convertible and Gran Coupe body styles.
