Enough driving has been done between tweaks and improvements to safely say that this project is still headed in the right direction. Lately, my 2014 Mirage is used as a comparison vehicle and the highest mpg with it is 72 mpg and the "normal" mpg is 48-52. These numbers are nothing to sneeze at even though the Mirage is a gas guzzler compared to Centurion.

The big difference is apparent when coming back from a drive in Centurion and then immediately taking the Mirage out on the same course. Centurion glides, the Mirage feels like it's going though honey. All coast down tests easily go to Centurion even though it's significantly lighter. Uphills are still a challenge for Centurion - but only the really long steep ones. Impressively though, Centurion will hold itself in high gear where other cars I've owned, failed to do so.

Traffic that is traveling at a steady 55-65 mph is absolutely passable with Centurion. 65 mph comes so easily these days that Centurion is now a very easy car to speed with, something that seems so unlikely with a little tractor engine... That's the latest...
