We had a 2015 Transit Medium Roof (6’) with EcoBoost. We averaged around 18mpg. Don’t think we ever quite reached 20. Not sure more speeds would impact that. It towed 5,000 lbs like it wasn’t there.
It burned Regular fuel, which is substantially less expensive than diesel, didn’t require DEF, and EcoBoost was about $2,000 vs $5,000 for the diesel. There are many former Sprinter owners on the Transit forum and fleet owners with both. The Ford dealer network has to be at least 10X the Sprinter network. YTD (March) Ford sold 31,841 Transits. Mercedes sold 5,517 Sprinters and 1,919 Metris.
We had two Chevy Cruze diesels in our fleet as well as a Cruze Eco (1.4L gas turbo). The TD’s cost $3K more, had a 4.5 gallon DEF tank in the trunk, and we had some problems with emissions equipment on both. So no way I was buying another new diesel.
