Talking about contemporary premium vehicles, one of the important components are offered as a form of luxury features is the gearbox.

Transmission has a difficult job, as a large capacity of modern machines mounted on vehicles are required to have a large output torque and strong. So, the gearbox in addition to handling all the power and torque at the same time claimed to be offering a very high level of refinement.

Some luxury cars on sale now use eight-speed automatic transmission that manages to accomplish these tasks and provide quick reaction and ensure good dynamics.

Now Mercedes-Benz plans to make improvements, with a German company, they work together to develop a nine-speed automatic transmission, as quoted in Autocar, Tuesday (07/20/2010).

A senior technician has given little leaks that the product is currently being developed, he also added that the next shipment will be used for powerplants with large capacity.

New transmission is intended to improve the efficiency offered by the various Mercedes vehicles. This gearbox is also expected to be able to offer a serious improvement in terms of fuel economy and CO2 emissions.

However, it seems that in the automotive world, the transmission with a ratio of more does not necessarily become a better package. Mercedes engineers have determined that nine is the maximum ratio that can now be offered for a gearbox.

The engineers who did the development offers two reasons for this. First of all, this is a technical limit of what can be achieved using current technology (we’re talking about efficient, something that can be developed). Second, the amount that is greater than the ratio would not be suitable for most of the capabilities of the driver and will only create more confusion. — Toto Prayogo
