My 2018 Explorer XLT (same as 11-19 Explorer) is actually wider than the current Ranger and maybe the same weight or heavier. I have the N/A 3.5L stock 290 hp, but I tuned it and they are known to pretty much cap out around 315-320 hp. I have to strategically merge onto the freeway because...
You're right, I forgot about the 8 foot bed being available with the 3.5 EB. But a 5.5 or 6.5 foot bed Regular Cab would be lighter. I'm not sure exactly why the Tremor didn't sell, but I know I would want 4x4 with the 3.5 EB for the dragstrip.
I doubt Ford will offer the 2.7 EcoBoost on the Ranger because it'd be much faster than the F-150. Just like they do not offer the 3.5 EcoBoost on the F-150 Regular Cab w/ 4x2. It'd be super light with a lot of power, kind of a cheap Lightning setup.
I have the 2.7 EcoBoost V6 in my Fusion...
Not sure if that is supposed to be on all EcoBoost engines, but none of mine really felt different after 1k, 5k, or 10k miles. I'm curious about the Ranger's daily driveability as well and eager to hear the OP's report.
