German supercar maker Porsche has been accused of manipulating emission results using a cheat device attached to the steering wheel, which alters the emission output. A similar accusation had dogged the heels of Audi, another supercar maker, which resulted in the recall of 24,000 A7 and A8 models. Now Germany’s Transport Authority, KBA, is investigating if Porsche was using a similar method to manipulate the emission output. The authority believes that the cheat device attached to the steering 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 has released a statement denying this accusation.
