lol my friend has a viper and it does not get even close to 13....so msg fuel.poop to change their stats because i highly doubt a v10 600 hp viper is going to get better mpg than a 425hp v8.....and rich people like to save gas too... get the r/t if the extra ponies isnt a big dealfor u cuz u save alot of money stickin with the r/t the mpg are pretty much the same as the srt8.


edit** i didnt take account weight difference but the challenger should ge tbetter mpg than wat paper says charger srt8s are getting 15-18 city so i expect people to give more info as they fill up and drive.
