The Honda Odyssey has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Acadia doesn’t offer a front passenger side knee airbag.

Using vehicle speed sensors and seat sensors, smart airbags in the Odyssey deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The Odyssey’s side airbags will shut off if a child is leaning against the door. The Acadia’s side airbags don’t have smart features and will always deploy full force.

The Odyssey has a standard Whiplash Mitigation Front Seat Design, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Mitigation Front Seat Design system moves the headrests forward to prevent neck and spine injuries. The Acadia doesn’t offer a whiplash protection system.

The Odyssey’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Acadia doesn’t offer a driver alert monitor.

Both the Odyssey and the Acadia have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available rear parking sensors.

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Odyssey is 1.5% to 2.8% less likely to roll over than the Acadia.

The Honda Odyssey achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Acadia is not a “Top Safety Pick” for 2024.

Warranty

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

Honda pays for scheduled maintenance on the Odyssey for 2 years and 24,000 miles. Honda will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. GMC only pays for the first scheduled maintenance visit on the Acadia.

Reliability

The engine in the Odyssey has a single overhead cam for simplicity. The engines in the Acadia have dual overhead cams, which add to the number of moving parts and the complexity of the cylinder heads.

J.D. Power and Associates rated the Odyssey second among minivans in their 2023 Initial Quality Study. The Acadia was rated third in its category.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Honda vehicles are more reliable than GMC vehicles. Consumer Reports ranks Honda 19 places higher in reliability than GMC.

Engine

The Odyssey’s 3.5 SOHC V6 produces 52 more horsepower (280 vs. 228) and 4 lbs.-ft. more torque (262 vs. 258) than the Acadia’s standard 2.0 turbo 4-cylinder.

Fuel Economy and Range

On the EPA test cycle the Odyssey gets better mileage than the Acadia:

			MPG
Odyssey
	FWD	3.5 SOHC V6	19 city/28 hwy
Acadia
	FWD	3.6 DOHC V6	19 city/27 hwy
	AWD	3.6 DOHC V6	19 city/26 hwy

To lower fuel costs and make buying fuel easier, the Honda Odyssey uses regular unleaded gasoline. The Acadia with the 2.0 turbo 4-cylinder engine requires premium for maximum efficiency, which can cost on average about 82.8 cents more per gallon.

The Odyssey has a standard locking fuel door which locks and unlocks with the power locks. The fuel filler door is not lockable on the Acadia. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

Transmission

A 10-speed automatic is standard on the Honda Odyssey, for better acceleration and lower engine speed on the highway. Only a nine-speed automatic is available for the Acadia.

Brakes and Stopping

The Odyssey stops shorter than the Acadia:

	Odyssey	Acadia
60 to 0 MPH	123 feet	126 feet	Motor Trend

Tires and Wheels

The Odyssey’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the Acadia SLE/SLT’s standard 65 series tires.

For better load carrying, ride, handling and brake cooling the Odyssey has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Acadia AT4.

Suspension and Handling

For a smoother ride and more stable handling, the Odyssey’s wheelbase is 5.6 inches longer than on the Acadia (118.1 inches vs. 112.5 inches).

For better handling and stability, the track (width between the wheels) on the Odyssey is 2.8 inches wider in the front and 2.7 inches wider in the rear than on the Acadia.

Passenger Space

The Odyssey has standard seating for 8 passengers; the Acadia can only carry up to 7.

The Odyssey has 19.8 cubic feet more passenger volume than the Acadia (163.6 vs. 143.8).

The Odyssey has .7 inches more front headroom, 2.9 inches more front hip room, 3.7 inches more front shoulder room, 1.2 inches more rear legroom, 11.5 inches more rear hip room, 2.9 inches more rear shoulder room, 1.1 inches more third row headroom, 8.4 inches more third row legroom, 5.5 inches more third row hip room and 5.7 inches more third row shoulder room than the Acadia.

For enhanced passenger comfort on long trips the Odyssey’s middle and third row seats recline. The Acadia’s third row seats don’t recline.

Cargo Capacity

The Odyssey’s cargo area provides more volume than the Acadia.

	Odyssey	Acadia
Behind Third Seat	38.6 cubic feet	12.8 cubic feet
Third Seat Folded	92.3 cubic feet	41.7 cubic feet
Max Cargo Volume	158 cubic feet	79 cubic feet

A low lift-over cargo hatch design makes loading and unloading the Odyssey easier. The Odyssey’s cargo hatch lift-over height is 22.5 inches, while the Acadia’s liftover is 32 inches.

The Odyssey’s cargo area is larger than the Acadia’s in almost every dimension:

	Odyssey	Acadia
Length to seat (3rd/2nd/1st)	25”/56”/91”	18.5”/48”/83”
Max Width	50”	50”
Min Width	48”	42.5”
Height	54”	33”

The Odyssey has a standard One-Motion Magic Seat third row seat, which folds flat into the floor. This completely clears a very large cargo area quickly. The Acadia doesn’t offer seats that fold into the floor.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Odyssey. The Acadia doesn’t offer locking storage for small valuables.

Towing

The Odyssey’s standard towing capacity is much higher than the Acadia’s (3500 vs. 1000 pounds).

Ergonomics

The Odyssey’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Acadia’s rear power window switches have to be held the entire time to open them fully. Only its driver’s window closes automatically.

If the windows are left open on the Odyssey the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the Acadia can only operate the windows from inside the vehicle, with the ignition on.

The Odyssey Elite’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Acadia’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The Odyssey’s headlights were rated “Acceptable” by the IIHS, while the Acadia’s headlights are rated “Marginal.”

The Odyssey Touring/Elite has a standard center folding armrest for the third row rear passengers. A center armrest helps make rear passengers more comfortable and can provide a barrier between children. The Acadia doesn’t offer a third row rear seat center armrest.

Economic Advantages

Insurance will cost less for the Odyssey owner. The Complete Car Cost Guide estimates that insurance for the Odyssey will cost $550 less than the Acadia over a five-year period.

The Odyssey will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Odyssey will retain 54.9% to 58.5% of its original price after five years, while the Acadia only retains 52.27% to 54.69%.

According to The Car Book by Jack Gillis, the Odyssey is less expensive to operate than the Acadia because it costs $673 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the Odyssey than the Acadia, including $125 less for front brake pads, $110 less for fuel injection, $22 less for a fuel pump, $34 less for front struts, $822 less for a timing belt/chain and $596 less for a power steering pump.
