^^ I hope so, too. Not saying the RS needs a huge tank, but a few more gallons than the FoST's tank would be nice. Maybe something like a 15 gallon tank....hopefully.I wouldn't plan for a big tank. I think CAFE standards will make it smaller to save wight and to squeeze out those extra tenths of a MPG out of the car. I hope I'm wrong.
Gas tank sizes:
ST = 12.4 gallons MPG = 23/32/25 Maximum Range= 285.2 396.8 310
RS = 13.9 gallons MPG = 21/29/23 Maximum Range= 291.9 403.1 319.7
