Hans Mezger, one of the finest automotive engineers of his generation, passed away at the age of 90 last week. In a career with Porsche that spanned almost 40 years, he helped design the original 911's 2-litre flat-six, oversaw development of the all-conquering 917 prototype and designed the championship-winning TAG Formula 1 engine. Dan and Andrew look back at a career that may never be bettered. They also talk about the state of modern car design. We hope you enjoy listening. Support DN on Patreon for exclusive content.
