Porsche is accused of using a cheat device on some of its vehicles.

The Volkswagen Group has been accused of manipulating tailpipe emissions by a watchdog group in Germany. This time the cheating allegations fall on the shoulders of the company's Porsche sports car brand.

The KBA motor vehicle authority, according to Germany's Wirtschaftswoche, is investigating whether Porsche used an emission cheating device in some of its vehicles. KBA believes that Porsche may have used a device that used steering wheel movements to detect if a vehicles was on a rolling road.

KBA has also launched a similar investigation into certain versions of Audi's A7 and A8 models. The group believes that those cars may have been rigged to pollute more when their steering wheels were turned more than 15 degrees.

Unlike VW's previous emissions scandal, the latest accusations involve the company's gas engines.

Porsche denies using any kind of cheating device on its vehicles. "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," Porsche said in an email to Reuters.

It remains unknown if Porsche vehicles were actually using some ind of emissions-cheating device, but we imagine we'll hear more on the subjects in the coming weeks and months.
