[QUOTE="Formula51, post: 3145520, member: 19833"] E. Green Cobra: Look up the weight of the Viper tires and wheels vs. the Z06 tires and wheels so we can have something to go on. I did it for the gears and it turned out you were wrong. I have never said the LS7 is SOLELY the reason for the better gas mileage, just that it is a major contributing factor. The larger tires and increased weight will have a "slight" effect on the Viper, but I believe it to be insignificant and we have to have some numbers to try and figure it out. We are talking about 6MPG highway, that is NOT a small amount. And 4MPG city is not that small of an amount either. "slightly" larger tires and 200-300lbs of weight just are not going to account for 6mpg at highway speeds no matter how you slice it. That is what I am trying to tell you. I would argue that the larger tires and higher weight probably account for the Vipers better gearing. Thus, the majority of the difference is in the engines and tunning. I wish we had engine dyno tests of fuel consumption over a period of time at a given rpm for each engine, but we dont. Who knows, I'm sure that info exists, but we may not be able to see it. To say the engines in these two cars are not major contributing factors to the miles per gallon achieved by them just does not make sense. I don't understand why you will not give credit where credit is due. [/QUOTE]
