I don't think he ever compares his Audi to a Ferrari. He just states that the Ferrari was available in a VERY small displacement V8. Would it make you feel better if he chose a different example?
In the US we get used to these HUGE displacement engines. A 5.7L V8. Yeah it's cool and all, but other companies come up with very nice engines that don't require that sort of displacement.
There's plenty of smaller displacement V8s. How bout a supercharged 4.2-liter V8, 400 horsepower engine in the Jag S-Type R? Doesn't Land Rover have a 4.2L V8 in the Range Rover? I know some of their stuff uses a 4.0 V8. How bout the 4.0L V8 in the Olds Aurora? The newest gen Taurus Shos are powered by a 3.4 liter 32 valve churning out a whopping 225hp. Or get into the 3.0L V8s used in F1 cars. If you don't realize that there's a purpose for utilizing a V8 setup instead of a V6 then you probably shouldn't be debating.
Given the choice between a Ferrari F40 and a Celeron I'd take the Ferrari
