The SE trim's standard features include 17-inch alloy wheels, automatic headlights, rear parking sensors, heated mirrors with integrated blind-spot sections, rear privacy glass, a keyless-entry keypad, remote locking and unlocking, cruise control, an auto-dimming rearview mirror, air-conditioning, a leather-wrapped tilt-and-telescoping steering wheel, cloth upholstery, a six-way power driver seat with manual recline and lumbar adjustment, 60/40-split folding second-row seats with an auto-folding passenger side, 50/50-split folding third-row seats, a rearview camera, Bluetooth, a 4.2-inch central display screen, Sync voice activation and a six-speaker audio system with a CD player, an auxiliary jack and a USB port.

SEL models are eligible for the 202A option package, which adds a power liftgate, blind-spot monitoring with rear cross-traffic alert, power-adjustable pedals, driver-seat memory settings, leather upholstery (vinyl for the third row), a 110-volt household-style power outlet, and an upgraded seven-speaker audio system.

At the top of the range, the Limited trim includes the 202A package plus 19-inch wheels, xenon headlights, LED taillights, power-folding mirrors, automatic wipers, additional metallic exterior trim, upgraded wood interior trim, ambient interior lighting, a navigation system (optional on SEL) and a 12-speaker Sony audio system with HD radio.

The 301A package is exclusive to the Limited and adds an automatic parallel parking system, adaptive cruise control, forward collision warning, a power-adjustable and heated steering wheel, a 10-way power front passenger seat, ventilated front seats and power-folding third-row seats.

The Appearance package, available on SEL and Limited models, adds 20-inch wheels, black exterior and interior trim, and upgraded leather upholstery.

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.
