BMW is gearing up for the following chapter within the legacy of the M3 Sedan, with the brand new era, codenamed G84, formally “confirmed” by BMW M’s CEO Frank van Meel. Whereas specifics are nonetheless underneath wraps, sources trace – as we reported final month additionally – that the upcoming M3 will function a 48-volt mild-hybrid system paired with a 3.0-liter B58 inline-six engine, bolstered by an electrical motor built-in into the transmission. The G84 M3 is predicted to be accessible solely with an eight-speed automated transmission and an all-wheel-drive setup, focusing on a beginning output of 525 horsepower. Our sources say to not anticipate a place to begin considerably larger than the present era as a result of the mild-hybrid tech just isn’t about energy enhance.
Given the early stage of the mission, many of those particulars may nonetheless evolve. One key facet into account is the powerplant itself. Whereas the B58 engine at the moment advantages from mild-hybrid know-how, BMW M would possibly in the end go for the higher-performing S58 engine—a confirmed 3.0-liter inline-six that may should be reworked to satisfy the upcoming EURO 7 emissions requirements. If chosen, the S58 would additionally incorporate the 48-volt hybrid system to optimize efficiency and effectivity.
What appears more and more sure, nevertheless, is that the G84 M3 won’t provide a six-speed handbook transmission. BMW has been regularly shifting away from handbook gearboxes, particularly exterior the U.S., the place demand for them has considerably dropped. With the G80/G82 M3/M4 and G87 M2 probably being the final M fashions to supply a handbook choice, lovers might must bid farewell to this beloved function as soon as the present era runs its course.
No Plug-in Hybrid, Fortunately
One factor is obvious: the G84 M3 received’t comply with within the M5’s footsteps as a plug-in hybrid. The reasoning behind this choice boils right down to a number of elements, essentially the most essential being weight administration. Including a big battery pack, as seen within the M5’s PHEV setup, would detract from the M3’s agility and responsiveness—two hallmarks which have outlined the mannequin since its inception. Retaining the M3 light-weight is paramount to preserving its motorsport-inspired dealing with and monitor capabilities.
BMW M3 consumers, in any case, are inclined to prioritize efficiency over electrical driving vary. This contrasts with the viewers for plug-in hybrids, who usually search the every day comfort of electric-only driving. Like Porsche’s upcoming hybrid 911, the M3 stays rooted in performance-first ideas, making the mild-hybrid system the optimum selection for sustaining driving pleasure whereas nonetheless assembly emissions laws.
Lastly, the M3’s smaller dimension presents packaging challenges in terms of a PHEV structure. Incorporating a big battery pack, cooling methods, and electrical infrastructure would probably compromise each inside house and the car’s general steadiness. These challenges are extra manageable within the bigger M5, however for the M3, a mild-hybrid system strikes the right steadiness between energy and weight.
With energy anticipated to vary between 530 and 560 horsepower (within the base mannequin), the next-generation M3 is shaping as much as provide exhilarating efficiency whereas staying true to its roots as a track-ready machine. Although it received’t match the sheer output of the M5’s plug-in hybrid system, the G84 M3 guarantees nonetheless a great mix of energy and agility—and fortunately with out the outsized kidney grille. The brand new BMW M3 G84 received’t arrive earlier than 2028.
