The standard engine for all 2017 Ford Flex models is a 3.5-liter V6 that produces 287 horsepower and 254 pound-feet of torque. A six-speed automatic transmission sends power to the front wheels by default, but all-wheel drive is an option for SEL and Limited trims. Though EPA fuel economy estimates are not yet available for the 2017, we don't expect them to change from last year. The 2016 Flex with this engine was estimated to return 19 mpg combined (16 city/23 highway) for the front-wheel-drive model and 18 mpg combined (16 city/22 highway) with all-wheel drive.
The Limited trim is eligible for the optional turbocharged 3.5-liter V6 that increases output to a heady 365 hp and 350 lb-ft of torque. All-wheel drive is standard with this engine, as are steering-wheel-mounted shift paddles. In Edmunds testing, an all-wheel-drive EcoBoost Flex Limited accelerated to 60 mph in 6.2 seconds, a quick performance for a mainstream three-row crossover. Fuel economy was downgraded slightly to 17 mpg combined (15 city/21 highway).
Properly equipped, the Flex can tow up to 4,500 pounds, regardless of engine choice. This figure is a bit below average for a three-row crossover vehicle.
