Safety Comparison

The middle row seatbelts optional on the Flex inflate when a collision is detected, helping to spread crash forces over a much larger area of the body and limiting head and neck movement. This can help prevent spinal and internal injuries. The Acadia Limited doesn’t offer inflatable seatbelts.

Both the Flex and the Acadia Limited have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available collision warning systems, blind spot warning systems and rear cross-path warning.

Warranty Comparison

The Flex’s corrosion warranty is unlimited miles longer than the Acadia Limited’s (unlimited vs. 100,000 miles).

There are over 79 percent more Ford dealers than there are GMC dealers, which makes it much easier should you ever need service under the Flex’s warranty.

Reliability Comparison

J.D. Power and Associates’ 2017 Initial Quality Study of new car owners surveyed provide the statistics that show that Ford vehicles are better in initial quality than GMC vehicles. J.D.

From surveys of all its subscribers, Consumer Reports’ April 2017 Auto Issue reports that Ford vehicles are more reliable than GMC vehicles. Consumer Reports ranks Ford 6 places higher in reliability than GMC.

Fuel Economy and Range Comparison

On the EPA test cycle the Flex AWD with its standard engine gets better fuel mileage than the Acadia Limited AWD (16 city/22 hwy vs. 15 city/22 hwy).

The Flex has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Acadia Limited doesn’t offer a cap-less fueling system.

Tires and Wheels Comparison

The Flex’s optional tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Acadia Limited’s 55 series tires.

Suspension and Handling Comparison

The Flex has standard front and rear gas-charged shocks for better control over choppy roads. The Acadia Limited’s suspension doesn’t offer gas-charged shocks.

The Flex has standard front and rear stabilizer bars, which help keep the Flex flat and controlled during cornering. The Acadia Limited’s suspension doesn’t offer a rear stabilizer bar.

The Flex’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Acadia Limited doesn’t offer drift compensation steering.

The Flex Limited AWD handles at .81 G’s, while the Acadia Limited AWD pulls only .78 G’s of cornering force in a Car and Driver skidpad test.

Chassis Comparison

The Ford Flex may be more efficient, handle and accelerate better because it weighs up to about 200 pounds less than the GMC Acadia Limited.

As tested by Car and Driver, the interior of the Flex Limited AWD is quieter than the Acadia Limited AWD:

Passenger Space Comparison

The Flex has 4 cubic feet more passenger volume than the Acadia Limited (155.8 vs. 151.8).

The Flex has 1.5 inches more front headroom, 1.3 inches more front legroom, .9 inches more rear headroom, 7.5 inches more rear legroom, .3 inches more third row headroom and .1 inches more third row legroom than the Acadia Limited.

The Flex Limited offers an optional rear tailgate seat that can be flipped rearward and used for tailgate picnics. (Do not use seat reversed while vehicle in motion.) The Acadia Limited doesn’t offer a rear tailgate seat.

Cargo Capacity Comparison

The Flex has a standard third row seat which folds flat into the floor. This completely clears a very large cargo area quickly. The Acadia Limited doesn’t offer seats that fold into the floor.

Pressing a switch automatically lowers the Flex’s second and third row seats, to make changing between passengers and cargo easier. The Acadia Limited doesn’t offer automatic folding seats.

Ergonomics Comparison

The Flex’s front power windows open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Acadia Limited’s front passenger window doesn’t close automatically.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Flex’s exterior PIN entry system. The Acadia Limited doesn’t offer an exterior PIN entry system, and its OnStar® can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.

Intelligent Access Key standard on the Flex SEL/Limited allows you to unlock the driver’s door, cargo door and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The GMC Acadia Limited doesn’t offer an advanced key system.

The Flex SE/SEL’s standard speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The Acadia Limited’s manually variable intermittent wipers have to be constantly adjusted. The Flex Limited’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.

To improve rear visibility by keeping the rear window clear, the Flex has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the Acadia Limited only has an intermittent setting, so in a hard rain visibility isn’t as good.

Both the Flex and the Acadia Limited offer available heated front seats. The Flex Limited also offers optional heated second row seats to keep those passengers extremely comfortable in the winter. Heated second row seats aren’t available in the Acadia Limited.

Optional air-conditioned seats in the Flex Limited keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Acadia Limited doesn’t offer air-conditioned seats.

A built-in pollen filter removes pollen, exhaust fumes and other pollutants from the Flex’s passenger compartment. This helps prevent lung and/or sinus irritation, which can trigger allergies or asthma. The Acadia Limited doesn’t offer a filtration system.

To keep a safe, consistent following distance, the Flex Limited offers an optional Adaptive Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Acadia Limited doesn’t offer an adaptive cruise control.

The Flex Limited’s optional Active Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Acadia Limited doesn’t offer an automated parking system.
