How does this cargo box affect gas mileage on an SUV like a GMC Acadia?

We used this box on a trip to California - 1800 miles an no appreciable difference in gas mileage noted. Very little noise from box as well. We were very happy! This was on a small SUV.

I have a small hybred and I lose 2 to3 miles per gallon. It is a very aerodynamic car. I would think the difference on a larger SUV would be a lot less.

I could see no noticeable MPG change when using this box. I consistently take 400 mile trips and have done so with and without the box. MPG seem to stay within my avg total over several trips.

Lisa I bought the tuner to go on a 2006 Chevy 3500 Express van. I pull a 30ft car trailer with it. I have had it for a month or two. I have seen a gas mileage improvement of 2 to 3 miles/gal. Which I drive long distances. It does improve the power and fuel economy. If you drive a lot a mile or two per gal is a great help.

I really don't know. I bought the cargo trailer as a gift and have never used it myself. I wish I could be more help. Have you tried googling to see if you could find an answer to this question?

As long as you keep your foot out of it and drive responsible there's a gain dependent on the vehicle. Otherwise it's about a two to three MPG loss hotroding around.

I have a Nissan Frontier, which has a built in channels to secure cargo into the bed of the truck. So, I tie it down with a cargo strap. This storage container is not designed to be attached to the truck bed itself.

I purchased this device once before in hopes of adding torque. It doesn't add torque or even increase the mpg on your vehicle. It does however, make a cool noise when you step on the gas. But there is also an annoying whistle sound when you're just driving around. So again, no actual benefits except for "performance sounds". I hope this response provides clarity in your decision.

i tried the milege mode on my 06 gmc 2500hd with 6.0L and 4l80e trans, it made the truck feel really sluggish and didnt seem to help the mileage any so i switched it to the performance mode. now it didnt make the truck super powered but it does seem peppier over stock and the trans doesnt gear hunt unloaded and less gear hunting when loaded, nice firm shifts but not neck snapping. down side is i have to use 90+ octane but truck seems to get a little better fuel mileage on the highway, city driving well its a heavy truck so i dont expect much from it lol

Had very little noise - if any - from the cargo box. What little noise heard was probably from my cross bars - and that was at highway/interstate speed. Cross bars with cargo (with load) affected mpg by about 5-10%.

Not much. The hitch tucks up in pretty tight under the bumper. The rear cargo floor is lower to the ground than the hitch.

The company claim it will increase fuel mileage but my experience is bigger tires less fuel mileage the tries weigh more there for more work for the engine to turn them and also now you are geared a little higher sometimes that causes a drop in mileage. Another thing to consider before purchasing is elc device are hard to get reimbursed so if you are considering trying and if it dose not do what you want it to do retuning it that could be a problem unless there is something wrong with the devise.

I have a traverse. With the third row completely up, you can't fit it in the cargo area; you'd have to fold the two seat section down to get it back there with the tray on.

It is curved forward and has securing straps that wrap around the head rest and outer side of seat to secure it. I used it in a GMC Yukon XL and there was some room at the top and down the sides so with some coaxing would work in smaller SUV. As long as you have something to attach the top and side to it should work. I made a 3000 mile trip with 3 german shepherds and 1 lab and despite trying to come over or around it stayed in place.

On my 2004 Jeep Grand Cherokee V8. I only noticed trying to save gas mileage only got 1-2 MPG improvement. The shifting does great and really smooth. I have a K&N; intake and still no performance difference. Idling was a little smoother. I have not tried the high performance feature. Towing feature does great lots of torque. Hope this is helpful.

I use the bag on a cargo carrier. As for carrying it on the roof, I can tell you than anything you haul that hinders the aerodynamics of the vehicle will play a factoring role in your fuel mileage. Your fuel mileage will drop, but "how much?" would be the question. As for the bag itself, it was a great purchase for me. Well worth every penny I paid. It's a very good quality bag.

I used the bag on the rear rack and my mileage improved 1.5 mpg! Must have been less wind drag. I liked the rear rack for ease of loading too.

It should. I used it behind the middle row bucket seats in a mini van. I'm not sure how the Acadia is, you may have to figure out something to block the bottom between the 2 bucket seats (I used a cooler). I also have big dogs that can't squeeze through the barrier and the sides of the car. For me, it worked great!

Based on your stated SUV mileage of 22 mpg my guess is you have something like a Ford Explorer. Given that, you'd have a front projected area of about 5,000 square inches. The Tahoe bag has a front projected area of about 650 square inches, an increase of about 13%. A very rough estimate could be same percentage but as a decrease in mpg, or about 3 mpg. Compressible fluid (air) dynamics is very complex though, this is just a rough guess based on general aerodynamics math relationships (force, power, area, velocity, etc.). Driving slower will considerably reduce the air resistance force, attaching an angled air dam in front of the bag in order to manage the air flow will probably help as well.
