The Eco is a brick, aerodynamically. That's why the new, bigger and heavier Escape with the 1.5 turbo gets better mileage than this car.
This is one of the reasons Ford is dropping the Eco and Fiesta. They're going to electric vehicles, and they make such good power, people will just opt for bigger over sportier. Your average consumer doesn't even know how to drive a manual, and doesn't care about performance, outside of image.
There will be small, sporty EVs, but that's a different kind of market. I doubt we'll ever see a subcompact EV from Ford in the US. If you like your Eco, keep it. Cars just get bigger from here.
I like mine because of the styling. I like the high ground clearance. I like it because the engine and transmission are proven reliable. I like it for the same reasons it's so popular in the 3rd world, and they didn't even get 4WD or the 2.0 Duratec. They got the 1.0 or diesels, with 5 speed manuals.
My other car is a Fiesta ST, like the one above. The 2 cars are from the same platform and have almost the exact same wheelbase and width. My Fiesta, with a 210 whp/276 wtq turbo engine, gets better mileage, especially at higher speeds than I would ever drive the Eco on the freeway. The Fiesta is way lower and slipperier and weighs 600 lbs. less, and it doesn't have a torque converter.
The biggest downside to the Eco is that it gets poor mileage for its segment. That's understandable. It's heavy, and about as aerodynamic as a semi truck. It's a tough little car, though, and it can tow and carry and get through more crap than you might think. I like how it handles a lot better than I thought it would. It's tall for such a small vehicle, but it doesn't feel tippy in corners, and it feels planted at any speed. I'm keeping mine until I can't.
