Having a 4 cylinder base engine is fine, but IMO it needs a V6 and/or diesel option as well. Doesn't even have to be the 3.5L EB, they did just throw a 335 HP, 380 lb-ft 2.7L EB in the Edge for the 2019 model. That would be a good option while still giving the 3.5L F-150 an advantage.
Not sure why I care though, I won't be buying one. I've got my 99 and 86 Rangers and they are probably the last Rangers I'll ever own. When the 99 gets replaced it will be with a classic truck, most likely a 60s F series (maybe a Ranger trim package). If the 86 gets replaced it'll be with a older muscle car or some sort of sleeper build. If I ever buy a newer truck it will be many tears after it was new.
