I've been criticized by a reader of my book "The Gold-Plated Porsche" for referring to "the Hirth engine" in a Carrera Speedster I once owned. He says there's no such thing and points out--correctly, of course--that it was designed by Fuhrmann and therefore should be called "the Fuhrmann engine" if you're referring to a four-cam 356/356A.

I'm sure he's right, strictly speaking, but I do seem to remember to casually referred to it as "the Hirth engine." Of course today Hirth makes everything from snowmobile engines to very light aircraft powerplants, so that term would today, certainly, be inaccurate.

But am I misremembering? Was "the Hirth engine" never a common term for Carrera engines?
