Here's my thoughts on on high end exotic cars.. I absolutely love them and I'll try my hand at explaining why.

The big 3 are fully capable of producing a motor similar to the Ferrari v12 I mentioned earlier. Why don't they? Cost. PROFITS. They are making billions doing what they do and there simply isn't a need to design complex engines. Again, they are fully capable, it's not rocket science. Building cars is a business first and foremost and it's all about profits.

Ferrari on the other hand.. Sell their cars for what they do because that's what it costs to design and engineer their vehicles in low volumes at the limits of modern day technology and materials because that is a part of its appeal to its customer base. The latest and greatest in technology.

The ls7 for example is cammed with a fuel economy and emissions cam for torque from the factory. An equivalent 7.0L Dohc motor can make a ton of torque down low and make a ton more hp up top as well. Why do ferraris not cam for lower Rpms ? Because large amounts of torque down low simply isn't needed for performance. Gears can add torque , gears can't add hp. So they are cammed and designed for top end hp and torque.

To me engines are air pumps. Dohc trumps pushrod everywhere except cost and simplicity (and packaging). The high end engines are cammed and geared for top end and max speed.. They don't come with a .50 Prius 6th gear that we have in the ZF. They simply could do that if they wished but they don't.

I'm rambling here lol.
