Porsche accused of manipulating emission results using steering inputs

Earlier this month Audi recalled 24,000 A7 and A8 models after the German motor authority charged them with using steering wheel angle to manipulate the nitrogen oxide emission figures. Now, Porsche has been accused for using a similar cheating technique.

KBA (Germany’s Transport Motor Authority) is investigating if Porsche was using a cheat device that is connected to the steering wheel to manipulate the emission output. The authority believes that this device identifies it as a testing cycle and emits less nitrogen oxide. If the steering wheel is turned more than 15 degrees, then the car emits excess nitrogen oxide. Porsche released a statement denying this accusation. 

"We can confirm for all Porsche models: We are not using steering movements for the sake of detecting a test bench driving cycle and reacting to it," said Porsche in an email statement. 

The Volkswagen Group will get a big blow if this accusation about Porsche turns out to be true. Until now, the sports car manufacturer has been maintaining a very clean image. In fact, the brand image of Porsche remained unimpaired even after the Volkswagen diesel scandal broke out.
