no dude. fuel tanks are sized for endurance, not to maximize storage. there's absolutely no point having a shopping cart with 2000 miles endurance - typical range of a u.s. spec gasoline vehicle is ~300 miles real world. you could easily double fuel storage on most vehicles if you utilize otherwise unused volume under seats, etc.,
bullshit. vw golf synchro sold in canadia - that's snow belt with a vengeance. look at some of the non-imported japanese stuff too.
bottom line, there are some great super-diesel vehicles out there, including small pickups, 4wd minivans, that we never see. [frod transit connect is diesel in every market except here.] and we'll never see them because they don't suck enough gas.
