He was also a board member, the first to be arrested in the VW cheating scandal
Volkswagen continues to investigate the source of the evasive diesel engine software internally, but it's reportedly not turning up evidence against three suspended top engineers.
VW fired three more execs as its diesel scandal deepens.
The engine in the coming Porsche 911 GT3 RS will be the heart of the turbocharged engines going into the 2016 911 range coming later this year. It will remain naturally-aspirated in the GT3 models, but get boosted help for every model below those. Elsewhere, the next Boxster and Cayman will get turbocharged four-cylinders, and a V8-powered mid-range Porsche supercar is still in the works.
