Clyde,
I was mighty impressed with the LFA I got to ride in.

Agree with you on the NSX.  Very nice car, but not impressive.

Fellippe,
Many years back the SAE published a paper on the relationship of parasitic loss vs. number of cylinders.  In short their findings were that the auto makers were doing it all wrong.  The best relationship numbers for efficiency were the I3, I5 and V10.  So the I4, I6, V6, V8 and V12 formats just weren't that sweet spot. There is a reason the F1 boys went to V10s many years ago.  And a stupid reason they have abandoned them.

Side note: I've talked to my friend, the F1 trackside support for a big name company (Brian, Clyde and few others know who I mean) and he said that with modern materials and valve trains they have minimized those relational differences but yes they still exist.  Its just physics and they haven't (yet) found a way around it.  But when everyone plays with the same handicap, it really doesn't matter.

The Viper V10 is the worst sounding thing... but I think that is because of the valve angles.   Sounds like a chainsaw to me.
My favorite.... Alfa Romeo V12 F1 motor.   efficient or not.

The LFA is a joke much like the NSX new version or old versions 
The Japanese don’t get it 
Never have never will
The tried there damnedest with NSX but fell way short of the mark
Japan builds reliable cars with no Panache !
Much like Porsche and Mercedes 
And blenders!

Do you guys think that if Ferrari eschewed turbocharging in their V8 cars, that at some point a V10 would be/would have been sought after once the displacement neared/exceeded 5.0 liters?
The Gallardo started off at a 5.0L, and the LFA a 4.8.....it seems this is the sweet spot for a flat plane crank exotic motor of 10 cylinders.
Maybe Ferrari goes back to the F310B just like they did the 641 for the F50.
I'm not a huge fan of the V10 sound, but seeing that the LFA made a pretty sweet sounding one, I'd imagine Ferrari would be able to do just as good or better.
