Porsche 911 Carrera obtains amazing fuel economy: just 6.7 Litres/100 km

Sports vehicles by Porsche get on record-breaking test drives time and again, however, this time the objective of the test was totally different. It is to drive a standard 345 hp Porsche 911 Carrera with Porsche's PDK Porsche-Doppelkupplungsgetriebe, the vehicle test driver, former racing driver and presenter of the n-tv Motor magazine Klaus Niedzwiedz traversed 648 kilometers or exactly 400 miles on public streets, attaining enormously low average fuel utilization of just 6.7 liters/100 kilometers, equivalent to 42.2 mpg imp.

He easily outdid the overall fuel consumption specified under the Euro 5 standard in the process which, at 9.8 litres/100 kilometers (28.8 mpg imp) already fixes the ultimate standard in this range of sports vehicles with regards to fuel efficiency.

The Porsche Carrera traversed around 190 kilometres/118 miles of the overall course on country roads and 30 kilometers/19 miles in city traffic, with the residual distance on the Autobahn.

The vehicle's gas tank was full before and after the test drive by an official inspector of the German DEKRA Car Inspection Authority, who also officially closed the fuel tank and the engine compartment in due process.

Under typical traffic conditions, with headlights on, and variable rain, the driver tried to maintain engine speed between 1,800 and 2,000 rpm and a street speed between 90 and 130 km/h (56 - 81 mph).

The average speed attained in the process was 84 km/h or 52 mph. The test driver, Klaus Niedzwiedz said, "the result proves that with a lot of feeling and discipline you can even drive a 3.6-litre, 345-bhp sports car very economically."

The test drive establishes once more that Porsche is in the right direction in its process of technological enhancement. In only a very short while, all production variants of the Porsche 911 with a naturally-aspirated engine have been transformed to brand-new engine technology highlighting DFI Direct Fuel Injection, boosting fuel economy in excess of 12 percent, and with a considerable increase in both torque and engine potency.

The 7-geared optional PDK transmission also makes a considerable addition to the vehicle's greater fuel efficiency, simultaneously providing the 6-cylinder versions even more energy and performance quality.
