Four-speed transmissions were replaced by five-speeds, then six, seven and now the eight-speed gearbox is king of the hill for automakers. Amazingly, eight gears might be a thing of the past, as Mercedes-Benz is working on a nine-speed transmission for its high-output, large-displacement engines.

But why stop at nine? Why not jump the gun to ten? The Mercedes engineers believe that nine ratios is the most a gearbox could handle. They even added that they feel it is the most a customer can handle as well. This nine-speed automatic will offer more than just an extra gear. Automatic transmissions are lighter, more reliable, less complex, and cheaper to manufacture than the dual clutch transmissions even though the dual clutch trannys can typically shift faster and are more fuel efficient than automatics.

Of course, we don’t know this for sure since Mercedes is keeping their press mouth shut for the time being. We’ll keep you posted on any other developments we find.

Sometimes the decision makers pass down the edicts to one-up the competition, or other non-technical orders that are expected to be met.

9 speed is just bragging rights to top BMW and Lexus. Nothing more, and it is futile. You don’t have to be an automotive engineer to see that, and not everything auto engineers do is pure as the wind-driven snow.

I have nothing to say about the 8 speed VAG box... but that 7 speed AMG box is actually pretty neat. It has wet clutches in place of a torque converter and is pretty snappy with the changes. However, I’ll agree that the regular MB 7 speed is a torque-converter slasher made for cruising duty.

dang, i bet if this came in to life. most of their cars will become more fuel efficient and more faster.

oh that was new, i guess they are the first one who uses the 9 speed auto trans, i bet most of the automakers will also follow.

9 speed? Now this is insane, it just a while when some brand released an 8 speed gearbox.

With added gears, there comes a point where to much isn’t a good thing. In my opinion 8 speed is already overkill and is only made for fuel economy for large torque monsters.
