The manual gearbox has been around for years on the tightrope within the motor world. More and more brands are abandoning it, emissions regulations are stifling it and suppliers are not exactly in favor of manufacturing it in smaller quantities. However, BMW’s M division has not yet signed his death certificate.
What BMW said. Sylvia Neubauer, Vice President Customers, Brand and Sales at BMW M, confirmed in an interview with the German media Automobilwoche that the division’s engineers continue to actively work to find a solution that allows the clutch pedal to be maintained in its future models. Neubauer did not go into technical details, but according to the publication, the executive “promises a solution.”
The technical problem. The obstacle is not so much power as torque. BMW M’s inline six-cylinder engines generate torque figures that current manual gearboxes cannot absorb without mechanical compromise. A clear example: the BMW M2 CS arrived without a manual gearbox option precisely because the transmission was not capable of managing the engine torque.
The same S58 that produces 553 HP in the 3.0 CSL has torque limited to 550 Nm with manual, while in other configurations it can deliver an extra 100 Nm. And developing a completely new and more robust manual transmission for use in only a handful of models is, according to the head of BMW MFrank van Meel, “something that does not add up economically.”
The possible solution: decelerated engines. What the engineers would be exploring is artificially limit torque output in engines that are paired with a manual transmission. It is not a new concept, it is already happening currently with the M2, whose automatic version has 50 Nm more torque than the lever variant. The question is whether buyers will be willing to accept that compromise in upcoming models.
What models are left with a manual. After the Z4 M40i goes out of production this month, BMW M is left with only three cars equipped with a stick shift: the M2, M3 and M4. The current M3 is close to the end of its life cycle, with a replacement expected in 2028. What we do not know is if its new generation will arrive with a manual gearshift. From BMW Blog they are not very clear. The M2 and M4, however, still have plenty of power for a while.
Why is it so difficult to save he manual. It is a constant pressure that comes from several fronts. Emission regulations in Europe they tighten more and more (in 2030, manufacturers must reduce fleet emissions by 55% compared to 2021) and automatic vehicles consume less in the approved cycle. Driving assistance systems are designed almost exclusively to work with automatic transmissions. And the transmission providers themselves They prefer to work with large volumesnot with short runs of manuals for niche enthusiasts.
What this means. BMW M isn’t closing the door, but it isn’t opening any wide either. The brand is betting on saving time (and not disappointing its most purist customer base) while solving an engineering problem that is very economical. If the solution is to decelerate the engines with manual transmission, that could generate debate among those who expect maximum performance in each configuration. But for those who value the driving experience over the information on paper, it may be enough.
