Car companies are on a huge campaign to lower vehicle weight because it affects mpg. The Gen 1 FFH went 600-700 miles on it's 17.5 gal tank. That's far more than a mid-size family sedan is expected to go. They've saved probably 30 lbs. in the Gen 2 with the smaller tank for almost zero cost. That's the Ford goofiness.
Yet Honda put a large tank in the Accord Hybrid & uses that as a selling point against the FFH saying that the Accord Hybrid is better because it has more range. It doesn't matter what consumers actually do, they're swayed by big numbers. That's the same thing that keeps most ppl from buying electric cars. Even if they average 20 miles a day and do a max of 50 miles a day except on rare occasions they'll look at a BEV with a 75-80 mile range and say that they could never do it.
