Nine-speed automatic transmission under development

If you really know your luxury cars, you’ll easily be able to discern a stark performance difference between European premium cars such as Mercedes-Benz, and JDM (Japanese Domestic Market) cars such as Honda, Nissan and Toyota. Heck, you’ll even notice a difference between European and American premiums. In what aspect? Well, the tranny mostly.

Mercedes-Benz cars exemplify true German engineering at its finest in
their transmission systems. And it just keeps getting better. To keep
up with their new line of powerful and fuel-efficient engines, the
company is looking to upgrade their transmission technology. There are
already cars that feature eight-speed automatic transmissions, so
Mercedes-Benz looking to set a new standard–nine-speed gearbox
technology.

It takes a lot of horses and torque to fully utilize all nine speeds,
though. That’s why such a development would likely be seen on
Mercedes-Benz models with hefty engines. Still, you can seek comfort in
the fact that an unnamed senior Mercedes-Benz engineer did confirm that
the technology is now under development.

You could say that Mercedes-Benz is looking beyond engine technology
to up their emission standards. A nine-speed transmission would allow
the engine to operate at lower rpm while still maintaining, or even
increasing, the vehicle’s speed. Thus, less emissions will be produced
as compared to a car cruising in fifth gear at 4,000 rpm. And with more
gear transitions, shifting is going to be a lot smoother.

Sounds very promising, don’t you think?
