Gustav Brunner
The D6 was designed by Gustav Brunner, who based the chassis around a carbon-fibre monocoque. To replace the previous year's Cosworth DFV V8, team owner Günter Schmid arranged a supply of BMW M12/13 4-cylinder turbocharged engines. A total of three chassis were built during the year. The D6 was trendsetting in the way that its chassis was shaped aerodynamically at the front end so that separate bodywork was no longer needed. In the years to follow this design philosophy became the standard in Formula One; McLaren was one of the last top teams to adopt it in 1992 on the MP4/7A.
