Ford Introduces New Efficient Transmission

Ford unveiled a new transmission today that should increase fuel efficiency and performance, while reducing maintenance. Dubbed “PowerShift,” the new six-speed automatic transmission would be Ford’s first implementation of a dual-clutch or automated-manual gearbox in North America.

In a nutshell, an automated-manual has more in common mechanically with a manual transmission than with a traditional automatic. The gearbox essentially consists of two manual transmissions that work in tandem; each with its own clutch. What does all this mean? Better mileage, while still feeling like a regular automatic to the driver.

This type of setup is already offered on various BMW’s, Audi’s, VW’s and Porsche’s.

We’ve tested similar set-ups before in Audi’s redesigned TT sports coupe. Senior editor Joe Wiesenfelder found that the system creates “blindingly fast shifts” and “better mileage than [a] manual” vehicle.

Ford expects its PowerShift transmission to be 9% more fuel efficient and weigh 30 pounds less than the four-speed automatic transmission found on the 2009 Ford Focus.

Ford’s gearbox will also be a “dry” system, meaning it will be sealed for life, requiring no regular maintenance like transmission fluid checks or replacement.

Ford wants to equip the gearbox to a compact car — like its Focus — by 2010.
