Later moved to the US and NASCAR after his Jaguar and Red Bull Formula 1 spells. Now runs his own business, Composite Fibreworks, which includes fabrication for a number of cars in a wide variety of racing series in the United States. More recently, he's been involved in the Haas F1 project and is the team principal for the new team which entered Formula 1 in 2016. He has a little involvement in the design department too, but Gunther has been heavily involved with promotion, management and administration for Haas rather than designing. Before he made it to Formula 1, he worked for years in rallying with Mazda, Lancia, Prodrive and Ford amongst others in numerous capacities. Steiner also worked in the DTM after leaving Jaguar.
