I believe that very little to nothing was changed from 19 to 20 as most of the changes were done for the 2019 model year. They both have the updated styling and larger HV batter compared to the 17 and 18 models. I am a little thrown off by the prices unless I got mine for an incredible deal. I paid Carvana $28,000 for a 2019 Fusion Energi Titanium with 5,200 miles on it back in the middle of December.
