Porsche comes clean over new emissions breach

Porsche has reportedly informed German authorities over potential inaccuracies with its emissions data for its 911s made from 2016 and 2017.

Porsche is said to have come clean following a story in

It's been reported that engineers testing the emissions of 911s, in the laboratory, made a miscalculation in the car's coefficient of drag with the net result, in the real world, the 2016 and 2017 models use more fuel and have higher emissions.

Releasing a statement, the car-maker confirmed the issue with its emissions and said: "Porsche has identified issues in connection with individual roll-out tests," adding, "the company is continuing its internal investigations in close consultation with the authorities."

In the wake of Dieselgate, Porsche was keen to stress the problem identified was not related to any engine management software and that it did not affect vehicle safety.

Under German law if the real-world fuel consumption and emissions deviate by more than 10 per cent from the car-maker's claimed figures owners can demand compensation.

Porsche has not yet announced how big the variation has been on the models affected.
