My 2021 Accord Sport is my third Accord lease. My last lease was an Ex. Supposedly the Sport took the place of the Ex, but it doesn’t have Blind spot warning system that was a good feature, doesn’t have rear seat vents for heat and cooling, but did add the infernal engine shutoff that I hate. Still hard to beat for the lease price.
The Sport didn't replace the EX trim level, the Sport Special Edition trim level was added when they deleted the EX trim for the 2021 model year. I think that the only thing that the Sport Special Edition doesn't have that the old EX trim level had is a moonroof- but they do include leather instead.
The Sport 2.0t trim level also has the stuff that you mentioned... but it's a lot more expensive than the Sport 1.5t trim level- about $4500 more.
The 2.0t Sport also doesn't have the auto stop/start system, as it isn't included with the 2.0t engine... although I bet that Honda is going to add it when the new generation comes out. Honda does put it on the Acura TLX- which also uses the 2.0t engine.
That Sport 2.0t trim level is, in my opinion, the best trim level for the Accord with the 10th Generation. You get the upgraded engine, most of the goodies, and is just a really nice overall package for the price. Don't get me wrong- I love my Touring, but the 2.0t is probably the best compromise between price and features.
