Five new chiefs for research, sales and production will lead Volkswagen, the automaker announced Thursday, including a new engineering chief to replace Ulrich Hackenberg, the longtime boss at the center of the diesel cheating scandal.

The automaker also announced a smaller, more linear organization for its chiefs. Volkswagen cut in half the number of managers who report directly to new CEO Matthias Müller, according to the automaker, which could help end the cutthroat corporate culture that contributed to the pressure to appease former CEO Martin Winterkorn.

“These structural changes speed up the decision-making process, reduce complexity and increase efficiency,” Müller said in a statement.

Ulrich Hackenberg, who was Audi’s chief engineer and among the first to be rumored to catch heat for Volkswagen’s diesel scandal, resigned Thursday according to the automaker.

Audi’s new chairman of its supervisory board, Matthias Müller, said Hackenberg was responsible for implementing designs such as the automaker’s current MQB global architecture and cars such as the A3, A4, A6, A8 and TT.

“Above all, the modular toolkit system is inseparably connected with the name of Ulrich Hackenberg. He had that idea already in the early nineties at Audi. Today, the entire Group profits from it,” Müller said in a statement.

Volkswagen lobbied hard in 2011 to receive the same — or higher — clean vehicle credits as electric cars, the New York Times reported Wednesday.

“They wanted a special deal for diesel cars that we now know weren’t even meeting the standard,” Margo Oge, a former director of the E.P.A. Office of Transportation and Air Quality, told the New York Times.

The LA Times reported that roughly $51 million in credits was paid by taxpayers in 2009 for diesel cars that lied about mileage and emissions — essentially a cheap bar trick.

When the next-gen Audi Q7 turns up in showrooms next year, it will be the first among Volkswagen AG’s offerings to have a diesel PHEV option.
