The Real Reason BMW’s M2 CS Doesn't Have A Manual Box

Earning that CS badge has not come without a major sacrifice

The ultimate iteration of the current BMW M2 was unveiled last month, but something was missing. We’re referring to the M2 CS, of course, which boasts more power and even beefier bodywork than the normal M2. Sadly, the CS is restricted to an eight-speed automatic transmission, with no manual option available as in the regular M2. It turns out that the boosted six-cylinder engine in the CS is simply too powerful for BMW’s six-speed manual.

Manuals Reserved For Less Powerful M Cars

Whereas the standard M2 develops 473 horsepower and 405 lb-ft of torque from its 3.0-liter engine, the M2 CS dials that up to 523 hp and 479 lb-ft. At Le Mans last weekend, BMW Blog spoke to BMW M’s head of R&D, Dirk Häcker, who confirmed that the manual gearbox can only handle up to 473 hp/405 lb-ft, while still being in line with the company’s requirements.

If BMW released the M2 CS with a manual, it would have had to reduce the engine’s outputs to a point where it would not have been enough to justify the CS badge. It decided against going that route, which means the only alternative was the automatic.

The larger M4 follows a similar recipe: In base 473-hp form, it has a manual, but the 503-hp M4 Competition only gets an automatic.

It may not have a manual, but the M2 CS is so powerful that your focus is probably better spent on watching the road ahead than shifting gears. This compact coupe will hit 60 mph in 3.7 seconds and top out at 188 mph, its performance also aided by a weight reduction of nearly 100 pounds.

Only One Manual M Car Has A More Powerful Engine

The limited and staggeringly expensive BMW 3.0 CSL conflicts Häcker’s statement somewhat, as it has a six-speed manual yet produced 552 hp. There’s a good reason for this, though.

“It’s nearly the same one [gearbox used by the M2 and 3.0CSL],” said Häcker. “The thing is, we have different requirements. I think everybody knows the 3.0 CSL is a very rare, exclusive car. It will not be driven every day. Also, not the mileage. So, we had a special commitment overall to use [the manual] there, but it’s not an option for a track tool or something like that.”

Interestingly, the 3.0 CSL is more powerful but less torquey (406 lb-ft) than the M2 CS, so it appears BMW even had to make some compromises in this 50-unit exotic to make it work as a manual.

Ultimately, BMW M surely has the expertise to develop a brawnier manual ‘box that can handle the M2 CS’ outputs. After all, much more powerful cars like the Cadillac CT5-V Blackwing (668 hp) and Lamborghini Murciélago (661 hp) have manuals. But developing an all-new manual for a low-volume car like the M2 CS may not have been worth the investment for BMW at this stage.

Although the ultimate M2 misses out on a manual, BMW is still keeping the stick-shift alive where it can. Thanks to strong demand, the Z4 roadster manual is sticking around for longer than anticipated. Together with the M2, M3, and M4, there are still (almost) a handful of new manual BMWs to keep purists happy.
