There is something menacing and terrible about V10 engines. They lack the vocal complexity of the V12 and they also lack the screaming elegance of flat-plane V8’s. What they have instead is pure terror.
For a few years, V10’s were all the rage in high performance cars of a particular sort. The outgoing M5 had one. The Dodge Viper had one. The Lamborghini Gallardo still has one. I once spent a working day a few inches ahead of 5.0-liter one installed in the engine bay of an Audi R8 and it sounded like Wernher von Braun on a very bad day.
