Porsche has released details of its revised 911, which has improved engines and the model's first-ever double-clutch gearbox.
The engine line-up features direct-injection technology for the first time, which cuts carbon dioxide emissions of the Carrera 3.6 to 225g/km, putting it in Band F for VED road tax. Despite this, power is increased by 20bhp to 345bhp and pulling power is up by 14lb ft to 287lb ft.
The 3.8-litre unit in the Carrera S now has 385bhp, up by 30bhp, while pulling power rises 15lb ft to 310lb ft.
The new seven-speed, double-clutch transmission, is called PDK, which stands for Porsche Doppelkupplungsgetriebe.
It helps cuts the CO2 output of the manual S slightly to 240g/km. The unit weighs 10kg less than a Tiptronic gearbox.
It also cuts acceleration times by 0.2sec: the Carrera now hits 60mph in 4.7sec, and the S in 4.5sec.
The optional Sports Chrono Package Plus, which includes launch control, cuts the 0-62mph time by a further 0.2sec.
The mildly restyled body has new air intakes, new LED driving lights, and the rear lights now use LEDs. New 18- and 19-inch wheels are available, and the rear end has new exhaust pipes
Changes to the interior are minimal: the touch-screen is now slightly larger, and there's the option of ventilated seats.
Porsche is increasing the price of the 911 to coincide with the new model. The 3.6 Carrera now starts at 63,070, a rise of 1450, while the 3.8 Carrera 4S starts from 77,650, a rise of 4700.
