What we know about the BMW M3 G84
A plain-language guide without filling unknown specifications with guesses.
BMW M leadership has confirmed that a six-cylinder combustion M3 will continue alongside the electric M car. G84, 2028 production, xDrive-only and transmission details are specialist reporting rather than a published BMW model specification.
What is already known. BMW M says the combustion M3 will use a six-cylinder engine and will not be a plug-in hybrid. BMW design leadership says combustion and electric M3 branches will share the same design and digital language.
What specialist sources report. G84 production is reported for 2028, likely with an S58-derived 48V mild-hybrid system, automatic transmission and all-wheel drive. Reported outputs are excluded because BMW has not published them. What remains unknown. Final engine, power, transmission, driven wheels, body derivatives, dates and prices are unconfirmed.
