The wait for the next evolution of the Porsche 911 is almost over. In fact, we’re so close to the launch date that Porsche has just entered the teasing phase releasing the first official video of the sports car shot during hot weather testing in South Africa.

The public will have its first chance to see the new 911, codenamed 991, at the 2011 Frankfurt Motor Show in September. What we know up until now is that, the 911 will look like, well, a 911 – don’t forget, it’s all about evolution when it comes to Porsche's most famous model.

However, the next 911 is slightly bigger and roomier yet lighter than today’s version, and will be available with more fuel efficient and greener engines including a smaller displacement 3.4-liter flat-six with 350HP for the Carrera /4, and a 3.8-liter flat-six producing 400-horses for the Carrera S/4S,

The two launch models will be offered with a new 7-speed manual gearbox and a 7-speed dual-clutch PDK transmission.

The new 911’s lineup will eventually grow to include several body styles such as the Convertible, Targa and most likely a Speedster, as well numerous models and special editions like the Turbo, Turbo S, the GT series and more.
