Mercedes-Benz will put more energy into creating a new speed shifter for nine large displacements. While other car still offers a four-speed automatic transmission, the Mercedes-Benz believe that the nine-unit high speed CO2 emissions and fuel economy standards while allowing for high performance aircraft engines.

Mercedes-Benz will be for a maximum speed of nine technical support for traditional combustion engines. So far, no other cars that are interested in more than eight units of speed. Audi’s Toyota and Chrysler have recently joined in the effort to offer eight-speed version.

9g-Tronic gearbox will be a big improvement on the seven-speed 7G-TRONIC be. It will probably make his debut at the 2012 S-Class. seven-speed automatic transmission 7G-TRONIC transmission was the first introduced in 2003. However, recently a new eight-speed ZF transmission used by BMW and Mercedes-Benz, Audi has a higher position.

Audi has announced that all 2011 primary lineup, namely A4, A5 and Q5 will be an eight-speed automatic transmission have to be branded Tiptronic. 2011 BMW X6 will release eight-speed version.

auto shift automatic transmission ratios of gears as the car moves, so that drivers do not have to manually change gears. larger cars and the traffic is worse is the incentive for the car to the transmission from manual to automatic improvement. Cars with such transfer has been sold in North America since 1950. In Europe, transfer, such as less popular and the Asian markets, automatic transmissions have become popular since 1990.

Cars with automatic transmission can be driven with more ease. Henry Ford’s Model T is an important development in the history of the automobile transmission. ZF Friedrichshafen with BMW’s were the first the first six-speed entered in 2003, came with the Mercedes seven-speed 7G-Tronic-Benz and Toyota introduced the eight-speed Lexus LS 460 in 2007.

ZF has developed eight-speed automatic transmission to achieve 11% fuel savings, as priorities were not the amount of gear, but the minimum consumption. Transmission six-speed developed by ZF in 2006, has a high standard at a faster reaction time of human perception, adaptive control software that can read the intentions of the legs of the driver. The new standard is aimed at improving fuel economy. However, eight-speed transmission also has a shorter acceleration step, ensure faster acceleration and shift quality improved. Only 200 milliseconds required for eight-speed automatic gearbox gear to perform.

If a four-speed automatic transmission decades ago looks very refined, automakers have recently added songs continuously. However, it seems that nine speed. One factor is that consumers do not seem interested in receiving more. Although most drivers assume a six-speed automatic transmission is more comfortable than the older four-speed development of new transmission costs are not outweighed by the potential fuel savings. Changing gears in the eight-speed cars are so subtle that the other teeth will not be considered the destruction of the earth.
