Gustav Brunner
However, Schmid used his muscle in the German auto industry to secure a supply of BMW's powerful BMW M12/13 4-cylinder turbocharged engine for 1983. ATS fielded a single new Gustav Brunner D6 for Winkelhock. There were some excellent qualifying positions and races from the German, but the constant turnover of backroom staff meant that reliability issues were never solved, and 8th place at the European Grand Prix was his best result.
