The facelifted 911 Turbo range is expected to get an extra 15kW to give it an edge over the new Nissan GT-R and return it to supremacy at the Nurburgring’s Nordschleife, or Northern Loop. The power gain is due to the addition of a new direct-injection fuel system, which is also expected to improve fuel efficiency. In the updated 911 Carrera S, the direct-injection system netted improvements of 12.8% in fuel efficiency and 14.5% in carbon-dioxide emissions due to the more even dispersion of fuel droplets and the more complete burn that results.
Visually, the car is expected to receive larger front air intakes and new fog-lights in the front bumper, giving a more aggressive look. At the rear are a new set of LED taillights and a new diffuser similar to that on the new GT3. Daytime running lights may be added, as well as optional upgrades to larger wheels.
