Ford Flex missing EcoBoost
 

It's been awhile I've looked through the Fuelly data for an entire model of car.

The Ford Flex has a glaring flaw. Although two engine choices are listed, they're indistinguishable in Fuelly's menu. The Flex has a 3.5L normally aspirated engine, as well as a 3.5L turbocharged EcoBoost. Yes, they're both 3.5L, but the drop down doesn't differentiate turbo from n/a.

The EcoBoost is the only way to get AWD on this vehicle.

There are other dropdowns for trim and body style. The trim has zero impact on fuel economy, and there's only one Flex body style.

The MPG determinants not listed are wheel size and maybe roof rack.
