Volvo joins the ranks of car manufacturers with twin clutch gearboxes, made extremely popular by Volkswagen with their BorgWarner DSG. Volvo’s twin clutch transmission is a 6-speed unit called Powershift.
Powershift is a wet clutch gearbox, with one clutch for the odd gears and reverse gear, while the other clutch handles the even gears. Like other twin clutch systems, the next gear is preselected so upshifts can be done nearly instantly, giving a continuous flow of power without disruption because of gear changes.
The first production Volvo cars to be fitted with the Powershift transmission will be the 136hp, 320Nm 4-cylinder turbodiesel variants of the Volvo C30, S40 and V50.
