You’re right on the qualitative differences but the output gap is significant. The Ferrari motors puts out over 100hp more than its Porsche contemporary despite smaller displacement. But Ferrari has always been a terrific engine shop with a car building business attached to it. That 30 year old design was (and is) pretty impressive - 110 hp per liter naturally aspirated, flat plane crank, 5 valves per (tiny) cylinder, 8500 rpm redline and quite the screamer at the top. That said I really enjoy the air cooled flat 6 as well, especially at relaxed speeds and partial throttle where the Ferrari is just not really enjoying itself. They have vastly different personalities and I can’t really pick a favorite (at least when you wrap the rest of the car around the engine - on a pure engine to engine basis, it’s hard not to give it to the Ferrari) Anyway, I’m reminded of how much I enjoy these old lumps as I drive my dad’s Taycan Turbo S around here in Florida this weekend. It’s way faster than any car I own but mine have a lot more personality and character.
