Detroit: Volkswagen chief executive Matthias Mueller has apologised for cheating diesel car emissions tests on his first official US visit since the scandal broke in September.
"We know we deeply disappointed our customers, the responsible government bodies, and the general public here in America," the head of the German carmaker said at a media reception on the eve of the Detroit auto show.
"I apologise for what went wrong at Volkswagen," he added, promising that the auto giant is "fully committed to making things right." Mueller also said Volkswagen plans to make an additional USD 900 million investment in the United States to build a new mid-size SUV.
The investment at VW's Chattanooga plant will create approximately 2,000 jobs, Mueller said. "The US is and remains a core market for the Volkswagen Group," the CEO said, as his company battles to overcome a deep crisis over the emissions scandal.
The Wolfsburg-based group admits it installed software in around 11 million diesel cars of its VW, Audi, SEAT and Skoda brands worldwide that helped them evade emissions standards.
The so-called defeat devices turn on pollution controls when the car is undergoing testing, and off when it is back on the road, allowing it to spew out harmful levels of nitrogen oxide.
The affair severely damaged Volkswagen's reputation and spawned a host of investigations in several countries. VW has been tight-lipped about Mueller's schedule during his visit, but the US Environmental Protection Agency has said he is scheduled to meet with its administrator Gina McCarthy on Wednesday.
