Oops...LOL Forgot we were talking Flex...not that I didn't believe you...but you got my wheels turning so I thought I would check it out. Found this out -
According to edmunds:
Taurus Limited - 3,969 (FWD FFV) 4,196 (AWD FFV) 4,341 (SHO)
Flex Limited - 4,471 (FWD FFV) 4,643 (AWD FFV) 4,839 (AWD EB)
Explorer Limited - 4,557 (FWD FFV) 4,697 (AWD FFV) 4,859 (Sport)
Strong work! You were right on...only 20 lbs. difference between us...compared to the 500 lbs between you and your lighter counterpart.
FFV = Flex Fuel
FWD = Front Wheel Drive
AWD = All Wheel Drive
EB = EcoBoost (included on SHO and Ex. Sport)
All Flex Fuel's listed above are 3.5L NA V6
