Clearly, the rear of the BOcruiser drops away more rapidly than The Template. (So, according to Aerohead's theories, the upper rear should be in separated flow. Of course it isn't.)
And in fact - surprise, surprise, the rear shape is very similar to the Porsche Taycan, isn't it?
You know, someone looking at these could start getting the idea that The Template is of very little use indeed - not when the current slipperiest cars in the world show a quite different rear shape.
Gosh, who'd have thought it? I am just gobsmacked.
