In accordance with prophesy: 'A Type III Volkswagen of 1962, if equipped with a Coanda rear duct, [would have] a drag coefficient dramatically different to a Type 1.'
Both have 1500cfm of hot air to drive the effect. 1962 was Notchback only. Fastback, Squareback and the two convertibles came later.
I'm genuinely trying to learn*, and I was contradicting aerohead long before you came along. With more success I think. He puts spaces after sentences now. A small victory, but what have you achieved? Hmm?

Contradicting the modern assertion that the Coanda effect is passive.
