Porsche will be upgrading many of their 911 cars over the course of this year in order to keep up with the competition. They will be using newer engines and technology as well as improving upon the exterior design and look of the car. The updated models will include the 911 Turbo and Turbo Cabrio.
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 Nurburgringâ€™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.
Porsche has already applied direct injection technology to the 4.8-litre V8 Cayenne SUV but implementing the technology in the flat-six of the 911 models has been a more daunting task – although the payoff of greater power, torque, fuel-efficiency and emissions ratings was an enticing incentive for Porsche.
In line with the changes in the rest of the 911 range, the engine in the updated Turbo will also sport larger displacement combustion chambers, a new crankshaft and an upgraded oil and water pump. All of these features combine to create a more reliable and more powerful engine than the famous 3.6-litre turbocharged flat-six it replaces. Power levels will likely wind up near 375kW, which combined with the quick-shifting seven-speed Doppel Kupplung (dual-clutch) gearbox should ensure quicker acceleration and track times.
