So I drove both of the trucks today…..
2026 GMC Sierra 1500 Elevation 3.0 Duramax
2026 F150 XLT with 2.7L ecoboost.
Not a sizable difference in either one as far as acceleration goes.
Sierra
Plus: Dash seems much nicer and high end looking. Drivers seat very comfortable with plenty of room around me. The fuel economy will be far superior to the F150. Very stable and smooth on road handling. I like the looks far more than the F150
Negatives: No blind spot monitoring at this trim level. I have to stick with the Elevation for the front bench. No adaptive cruise control either, just lane keep assist and front end collision “notification” . No front bumper parking sensors. No 360 camera. Seats in back are not quite as comfortable as the F150
F150-
Plus: The 302A package I ordered on the one I placed at Sunrise Ford has all of the tech the Sierra was lacking. The Avalanche color. Higher ground clearance. Flat floorboard in the backseat. Dual power seats (vs Sierra only driver seat).
Cons- Lower fuel economy by a decent amount, chrome bumpers only for the XLT package with front bench. Cannot order the black appearance package with front bench. Rougher on road. More basic feeling dash and controls. $2800 more OTD than the Sierra. I have to wait 2-3 months for my special order truck to come in and the Sierra can be picked up this weekend.
I know there have been some concerns with the 3.0 Duramax and a few on here have voiced that they know someone who has had them. The powertrain warranty is 5yr/100k not that I want to have to use it though. I just want to make the best decision as I may be cut off after this one for a long time on buying trucks

. I don’t put a crazy amount of miles on my truck but I will defiantly put more than I have on my Ram since the new one will get better fuel economy and not force me to drive one of our smaller cars.
