When Porsche messes with a good thing, they make it better

4. You can get it with one of the world’s most advanced transmissions.

The 911 Turbo comes standard with a slick-shifting six-speed manual transmission. Available as an option is the seven-speed Porsche Doppelkupplung (PDK) automated manual, which replaces the Tiptronic six-speed automatic. The PDK uses two clutches, one to hold the current gear and one to ready the next. The dual clutch design means power to the wheels is never interrupted, which is a boon to acceleration and on-track performance. Left in Drive, the PDK shifts like an automatic. If you prefer, you can shift it manually through a pair of steering wheel buttons or optional paddles. We found the PDK works well for both track and street use, holding gears when you need the power and delivering decent fuel economy on the highway.
