First off you can never go by what the vehicle says your fuel economy is. Every car I've ever owned from Chevy to Hyundai to Ford to Oldsmobile to Porsche to Honda etc. etc. etc. they've always been off by at least 3 mpg or more and sometimes substantially more. Driving down long grades tricks my Hyundai into showing I got the fuel economy of a Prius at 45 mpg but in reality it was 28 mpg. I never trust the computer. The accurate way is to keep track of the miles you've driven per fill-up and divide it by the gallons you put based on what the receipt says. Your driving habits and the external environment also play a huge role. Fuel economy plummets the moment the turbo gets spinning and boost builds, even if you think you're driving conservatively. An example of this is driving in a headwind even at low speeds. In this scenario my F-150's boost gauge shoots up even though I'm light on the gas. The 2.0 won't be any different than my 3.5 EcoBoost. And immediately after filling up the vehicle will show fuel economy as being bad but it'll eventually stable out after driving many miles. The 2.0 isn't the most fuel-efficient I-4 in existence but the tradeoff is having lots of power on tap.
