Honda was clever here and essentially used the tried and true "lipstick on a pig" trick with the fuel gauge AND the temperature gauge. They are made to look digital via the trickery, but the actual gauge is an old mechanical swing arm gauge with lipstick for cosmetic appeal.The 1.5T has a mechanical (or electro-mechanical) fuel gauge? I didn't know that.
The fact that neither gauge is actually very linear in function was what drove me to check "behind the scenes" on these gauges early on for my 2017. Digital gauges, while they can be distorted by "garbage in = garbage out" generally speaking will track and report out gauge indicators in a more linear manner.
