The fact is modern gasoline engines are just getting more efficient ,my son in law just bought a new Mercedes 3.2E bluetech an it gets 39mpg. and for V8 power my GTO gets 26mpg which is pretty decent for a factory performance car ,my thoughts are the future engines will just be more efficient performance which means power adders such as turbos an SC's will be common on many vehicles ,even Palsut could retain his 3.1 and with the addition of a Turbo setup he could retain good gas mileage an have performance also,we come a long way since the muslecars of the 60's were a 350 hp car was lucky to get 14mpg.Chico(pops)
