Porsche’s CEO, Matthias Mueller, has never seemed convinced by making a variant of the VW BlueSport roadster – whose future is now in doubt – to sit beneath the company’s Boxster.

At the Paris motor show in 2010 Mueller told me there was no point making the BlueSport just for the sake of increasing Porsche’s production volumes; regardless of how much Volkswagen’s advisory board wanted him to do precisely that, from 100,000 to 150,000 cars per year.

Mueller argued that, if the new car stole sales from the more expensive (and more profitable) Boxster, Porsche could find itself in the unenviable position of making more cars but less money. Chase profit, not volumes, he said.

All reasonable enough. After all, how cheap could a sub-Boxster Porsche BlueSport be? Maybe £25,000? More likely £30,000. Close enough, in price and practicality, that even if it reached a new generation of Porsche buyers, it would tempt more still existing ones at the expense of its profitability.
