German regulators are investigating whether Porsche illegally manipulated fuel-economy data onits vehicles, potentially opening a new front in parent Volkswagen AG's emissions-cheatingscandal.
Germany's Transport Ministry and Federal Motor Transport Authority are examining whetherPorsche installed devices allowing its cars to sense whether they were being tested for fuelconsumption and carbon-dioxide emissions, representatives at both agencies said on Thursday.
That type of technology can be used to falsify results by making cars appear more energyefficient during tests.
Porscherejected allegations that its cars manipulate test results, a spokesman said by phone,adding that the Stuttgart, Germany-based maker of the 911 sports car is cooperating fully withthe authorities on the investigation.
Volkswagen has so far set aside 18.2 billion euros ($19.7 billion) for fines and related expensesafter acknowledging last year that it rigged 11 million diesel vehicles to cheat on emissions tests.
The revelations have increased scrutiny of auto emissions with regulators around the worldstepping up investigations. German magazine WirtschaftsWoche reported earlier thatunidentified people close to Porsche tipped off the Transportation Ministry to the allegedcheating. According to the report, some Porsche cars can detect whether they're on a test bedbased on the lack of steering wheel movement during operation. German authorities started asimilar investigation targeting Audi in November, the magazine said.
Porsche said technology that allows its cars to sense steering movements are used to improvethe car's performance when driving and are not related to emissions testing.
The shares of Volkswager have lost almost 20 percent since the scandal broke in September2015, reducing the company's valuation to 67 billion euros.
