Porsche continues to offer the next-generation of its model series with very minimal changes. Today the Stuttgart automaker revealed the facelifted 2009 Porsche 911 coupes and cabriolets. While the 2009 Porsche 911 may look the same visually, for the first time ever, a Porsche sports car gets direct-fuel injection coupled with an optional double-clutch gearbox.

The new Porsche-Doppelkupplung double-clutch 7-speed automatic gearbox replaces the former Porsche Tiptronic S-automatic transmission of both Carrera models. Porsche says PDK improves the cars acceleration and fuel-economy.

Output on the 2009 Porsche 911 Carrera with its 3.6 liter unit is increased by 20-hp to a total of 345-hp. Without PDK, the Carrera Coupe gets a combined fuel-economy of 25.7mpg (or 21.3mpg in U.S. standards) - with PDK the Carrera gets 28.8mpg (or 24mpg on the stateside. The 2009 Porsche Carrera S and its 3.8 liter unit are now up by 30-hp to a total of 385. The 2009 Carrera S now has a top speed of 186mph.

The 2009 Porsche 911 will be available on July 5th with U.S. pricing to be announced.
