The new Porsche 911 is the most revolutionary yet, with more efficient engines, a seven-speed manual box and braver styling.
The most dramatic changes are the more bulbous headlights, with daytime running lamps, as well as sharper tail-lights inspired by the 918.
Inside is a Panamera-style sloping centre console, although the driver-focused 911 makes do with far fewer switches.
Under the skin, the front suspension and steering set-up are shared with the forthcoming Boxster and Cayman. The rear suspension remains unchanged, but lightweight materials reduce the car's weight by up to 45kg.
Porsche will continue to offer its PASM damper system, which allows owners to choose between a series of different driving modes.
