Getrag has begun series production of the newest member of its Powershift transmission lineup, the dry dual clutch 6DCT250, at its plants in Irapuato (Mexico) and Modugno (Italy). The 6DCT250 transmission will first be introduced in the Renault Mégane and the Renault Scénic and for the NAFTA market in the Ford Fiesta.
The 6-speed, front-wheel drive transmission makes reductions in fuel consumption of up to 20% possible compared to a conventional torque converter automatic transmission, according to Getrag. For 2010, quantities of more than 100,000 transmissions are planned; this will increase to more than 400,000 per year by the end of 2011. The 6DCT250 was developed for integration in small- and medium-sized cars.
The 6DCT250 front-transverse transmission has six forward gears and one reverse gear. The even (2, 4, 6, R) and odd-numbered gears (1, 3, 5) are divided into two partial transmissions. The engine and the two partial transmissions are connected by means of a dry dual clutch.
The 6DCT250 is versatile in its application. It is applicable for both diesel and gasoline engines, Getrag says, and a start-stop functionality can be installed without any modification or extension of hardware. The transmission can be combined with an all-wheel drive power train and, when coupled with an e-motor, can be applied as hybrid solution.
With the Getrag Powershift 6DCT250 we will usher in the second era of dual clutch transmissions. Due to the dry dual clutch and the electromechanical actuation, the transmission surpasses even the conventional manual transmission in fuel consumption and CO2 emission.

The Modugno plant is responsible for the complete manufacturing of the gear sets for Europe and the assembly plant in Mexico and additionally assembles transmissions for the European market. The Italian Getrag plant was redesigned and restructured for the new dual clutch technology and will be running at full capacity by 2012. The newly built Getrag location in Irapuato is responsible for the assembly, end of line control and delivery of the transmissions produced for Ford and was designed for this task.
A consistent common-part-strategy allows rapid and cost-efficient adaption to customer needs, Getrag says. Further, all variants can be realized with only one production line type.
