Why do the Vette/Viper get such lousy hp/liter of gas?
Just ran some quick little calculations.
Audi TT
1.8L engine @ 225hp = 125hp/L
Vette
5.7L engine @ 350hp = 61.4hp/L
Viper
8.0L engine @ 460hp = 57.5hp/L
What's the major factors causing such a big loss?
Car weight? Lack of turbos? A really heavy wallet??
Now if only we could squeeze the rumored V6 in the TT, wonder what kind of 0-60 time we would could get.

turbo is the major factor in the scenario you listed.....
The exceptions to the rule are some of the Honda products (yes Honduuuhh!)
I think right now the S2000 has the highest HP/ per liter than any other normally aspirated production car...
Integra Type-R is second I think

T-U-R-B-O-C-H-A-R-G-E-R is the reason for 125hp/L
Of course you meant Litre of displacement.
Non-turbo 1.8 Audi makes about 65-66 hp/L.
Newest Z-06 Vette is about 71 Hp/L.
Non-turbo Honda S-2000 is 120 hp/L, but it takes 8500 rpm or so.
Absolute state-of-the-art hp/L on gas without boost for a 'car' is about 285 hp/L, but it takes 18,000 rpm. (3.0L BMW F1)
For a boosted engine (not using gasoline) it's about 670 hp/L at 8000 rpm. (8.2L Top Fuel Dragster). That's 5500 ponies! It was higher in the 1.5L turbocharged F1 era. Maybe as much as 800 hp/L!
FWIW, a better comparison might be torque/L. Those numbers are most interesting. Another thread, perhaps.
My $.02
