The 2009 Porsche 911 has been formally unveiled, sporting lightly -tweaked styling, and important changes under the skin. The 3.6L and 3.8L engines to be found under the engine covers of Carrera and Carrera S models are new, featuring gasoline direct injection for the first time, and bringing more power and improved fuel economy in tow. The 3.6L engine now produces 345 horsepower (a 20-horse increase), while the 3.8 in Carrera S gets a 30-horsepower boost, coming in at a very healthy 385 HP. Both engines' fuel economy and emissions output levels are improved, with the Carrera Coupe boasting a 24 mpg (US) combined-cycle figure.

Also contributing to the cars' improved performance and fuel economy is the new 7-speed dual-clutch transmission that arrives for 2009. Dubbed Porsche-Doppelkupplung (PDK), it replaces the Tiptronic S in the Carrera and Carrera S. Visually, the 2009 Porsche 997 is freshened with bi-Xenon headlamps, LED daytime running lights, and restyled taillamps that now use LED illumination. Also in back, you'll see that the Carreras get ovoid dual exhaust outlets, while the Carrera S cars get a pair of double-barreled tips. The cars arrive in Europe next month with a U.S. launch to follow later in this year.
