I have a 130 mile round trip to my inlaw's that's a very consistent highway commute that I drive at 70mph. I was able to take it yesterday for the first time in our '25 GT with base wheels to see how the efficiency compared to both our '21 GT and our '22 premium ext awd.

Weather yesterday was 80-90 (80 first leg, 90 return leg). Climate use accounted for only 4% of the return trip...I didn't think to see what it was driving down there. There was almost no wind either direction.

The best my '21 GT ever managed was 2.6 mi/kwh at 70 with the shock flower power wheels/tires. I'd leave with 100% and could come back with around 40%. Rough total range capabilities at 70 mph = ~240 miles.

Our '22 Premium ext awd's best was 3.0 mi/kwh at 70 with the 19" premium wheels and factory tires. I'd leave with 100% and would come back with a hair over 50%. Rough total range capabilities at 70 mph = ~ 275 miles.

Yesterday our '25 GT managed 2.9 mi/kwh at 70 with base aero wheels and tires. I left with 100% and came back with 51%. Rough total range capabilities at 70 mph = ~265 miles.

It's not an earth shaking improvement, but it's nice to see that Ford filled the gap in range between the GT and the non GT models, and despite providing more torque and extended performance, still managed to improve range roughly 10% over the previous GT. I'm really looking forward to seeing the difference in cold weather with the new heat pump.

Very informative, but the real test is in winter

Hmm… this is interesting, thanks for posting it. I’m really interested in the efficiency in the shoulder seasons. Is the heat pump helping?

I think you’re saying that you’re seeing motor efficiency gains not climate gains. And that makes sense given ford’s in house motors.

Great to see.

Yes this is just the aero and efficiency improvements with the new rear motor.

The gap should be even wider in winter months thanks to the heat pump efficiencies.

LOL put my wheels on it and watch all of those gains disappear and worse. Good aero on your wheels. Bad aero on mine. ????

Self-inflicted though, Steve. And I agree. I wouldn’t be caught dead with these ugly aero wheel regardless of efficiency

LOL my lack of efficiency is totally self-inflicted. Bad wheel aero, driving style, etc. ????

Steve, both you and I are using our same aftermarket wheels/tires we had on our '21 GTPE's now on our '24 GTP's and you have not seen an improvement? While it is not huge I have! Where I used to get 2.6-2.8 mi/kwh on average driving back and forth to Sac airport (111 miles each way) I now get 2.8-3.0 mi/kwh. And while I know we should not use the GOM as a reference, my '21 would rarely see over 260 miles range at 100% charge while my '24 often sees 280 and higher (Iv'e had close to 300 twice). Range means nothing to me but I am getting close to what I used to get when I had my '21 Premium.

Mark, does your '24 have this additional rear diffuser? I wonder if the '25 is gaining any small improvements with this and/or the dimpled grille (lower drag like a golf ball?)

Mark, I haven't noticed much if any improvement in efficiency, but I also haven't really paid attention. Habit from driving the Blazer and the T/A. If anything I think it's worse since I tend to plant my foot in it more and longer (no more 5 second limit!). FWIW, my current GOM is 179 miles at 78%, which extrapolates out to 230 miles at 100%. ??

Greg, my 2024 does not have that extra piece. The rear belly pan looks exactly like the pan from the 2021. What's yours look like going further forward ?‍♂?

Interesting, thanks for confirming guys. It's not hairy cardboard anymore like I recall it being. All plastic now.

Interesting, those look like vortex generators, which help the flow stay attached while it comes up the rear diffuser. Definitely looks like Ford spent more time in the wind tunnel tweaking the aero for 2025.

"Harry cardboard" is more expensive and absorbs road noise better than smooth plastic.

Looks like they have provisions for a tow hook too.
