While other manufacturers continue to develop 10-speed transmissions, Mercedes says it will stick with its nine-speed automatic

MB does not plan to go beyond nine gears in its automatic gearboxes, a senior engineer has revealed.

Ford and General Motors are among those committed to developing a 10-speed auto. The Volkswagen Group has shelved similar plans.

Mercedes, meanwhile, intends to offer no more than nine gears, according to Marcus Sommer, Mercedes’ 4Matic all-wheel drive system engineer. He said the firm has run 81 billion different computer simulations for gearbox scenarios and believes nine speeds work best.

Mercedes’ nine-speed auto is being introduced across the range, including on the new GLS. The GLS 63 AMG still uses the old seven-speed ’box, but the nine-speeder will replace it. The firm has no plans to offer a more potent GLS 65 AMG version, though.

Plug-in hybrid tech will also have to wait until the next-gen GLS, due in 2018, because housing the powertrain from the GLE 500e would require removing the third row of seats.

The whole "who has more gears" race was getting ridiculous anyway. Add any more gears and you might as well have a CVT - no one wants that.
