Now maybe someone can help me with the engineering here, weight of the vehicle, technology, hence the $90,000 price tag, but why does an SRT 10 Viper get the same "listed" mpg city and more mph highway then the SRT 8 Challenger? I'm sure a lot of that has to do with, as I said, that $90,000 price tag and the technology, but I want to make sure since I'm having a hard time with 10 cylinders and 8.4 liters getting better mileage then 8 cylinders and 6.1 liters.
