2025 S650 Ecoboost Premium gas milage road trip

[speedracer43]

I took a road trip over the 4th from San Antonio to Tyndall SD, around 1050 miles one way. I was interested in what my gas milage would be. I was surprised on the way to South Dakota I drove to Salina Kansas around 750 miles and mileage was over 35MPG. From Salina to Tyndall SD, around 359 miles I was pushing 42MPG, but I had a pretty strong wind at my back. I have pictures to prove this if anyone doubts. On the way back it was non stop so I just measured the entire drive at 35MPG. This was my first road trip since I bought the car. In SA I am getting around 20-25MPG.

Cheers.

Pretty good. The best I've seen in the GT was 27, but usually 23 if I'm not in a hurry.

Sounds about right. I got ~36.7mpg on 200+ mile trips around Northern California, roundtrips to even out elevation changes. The fuel efficiency of the Ecoboost is shockingly good, especially for how fun and fast it is. These Ecoboost 2.3s and the BMW B48s are the best turbo 4s on the market these days. I think the BMW gets similar power and MPG figures, and also torquey down low

Short and to the point.... Ditto!

I just returned from a two week, 6000 mile "drive about" road trip to 13 mid / western states, less than 500 miles of the trip were driven on an interstate. My hand calculated gas mileage for the trip was 34.7 mpg. The cheapest fuel I bought was in Scottsburg IN - $2.99 per gal .... the most expensive was in Fairplay CO - $5.23 per gal. Already planning another trip for the fall.

Yes; hand calculated fuel consumption is good. Driven carefully, I've seen almost 39mpg, but my overall hand calculated consumption is 32.5mpg. It's my daily driver and I typically lean more on the "I'm not in a hurry and the police might be around" side of things...

This was mine on a GT, 662km to empty.
That's 413 miles.

I was shocked when I got 28 MPGs in my GT on 1500-mile trip from SC to PA and back to take my youngest son to see UP Big boy 4014 and 4012 side by side. Usually get 22-24 on road trips like this, but this was first time I had top up. Threat of rain kept me from dropping the top.

OP, you get a one-time pass as yours is an Ecoboost... For future reference, when comparing Mustang mileage, it's like golf, LOWEST score wins!
