www.porsche.com The design of this manual gearbox is based in principle on that of Porsche Doppelkupplung (PDK). Gears 1 to 6 have a sports ratio and top speed is reached in 6th gear. The additional 7th gear, however, has a long ratio, which reduces torque and helps to reduce fuel consumption. Lower engine revs at fast driving speeds also ensure a high level of comfort on long stretches of road. In addition, a gear indicator in the rev counter reminds you which gear has been selected. The upshift indicator in the instrument cluster helps you actively conserve fuel. Thanks to the elevated center console, the gear lever is within easy reach -- ideal for sporty gear changes.
