911 Turbo S (Germany, 2013)

The 2013 911 Turbo S was unveiled by Porsche which improved power by about 5%. The engine has turbos with variable vane turbos. However, it is equipped with start/stop and a coasting function for the first time. It reduces fuel economy by 16% to 9.7l/100km. The only available transmission will be the seven-speed dual clutch transmission.

The Turbo S will do it in 3.1 seconds. Both cars have a top speed of 318km/h.

The 911 Turbo S is much more than just a powerful engine stuffed into the standard car. It is the first 911 ever to come with an active anti-roll system.

It also gets a different all-wheel drive system from other Porsches that includes an electronically operated, mechanical center differential to balance power between the front and rear. The system is also liquid-cooled so that it can send the cars’ full torque to the front wheels when needed.
