Roof cargo basket rack and mpg!

[Happy Hummer]

Took the H3 to Cedarburg today and wow with new cargo rack got less than expected mpg. Just didn't realize the dramatic drain of mpg till got back.
On a side note it was a beautiful day and we enjoyed our annual outing as always. Saw a H2 in town.

Yeah, when I put on my roof rack my mileage dropped just noticeably. So adding up my leveling, 35's, roof rack, rock rails, UCP, and brushguard, I noticed a drop of about 2 mpg.

 

[Hunner]

What's a mpg?

I had an MGB at one time.

 

[rsc]

Me too, didn't get much better mileage than my H3 as I recall. 20-22 everywhere.

Full length Gobi ranger rack, 2nd spare, BA bumper, rock rails, ucp....12mpg highway!! :horns:
Sometimes better. Oh and tha'ts with a set of 32's on there. Luckily for me i live maybe a mile from work so the truck doesn't even get hot by the time I get there.
I turned a brick into an even bigger brick.

I didn't buy a Hummer to save gas... I bought it to drive over zombies!

I get 17-20 everywhere with my roof basket. It's got leds and an awning and a hi lift for extra drag. I don't have a basis for comparison since it's been on for a while. I will say that it does catch more crosswinds on the highway. Not like our trucks are real aerodynamic but I did notice the gusts pushed the truck around a little more.

I get 10-12mpg with an uncalibrated speedo. Only 35's and a rancho

 

[Happy Hummer]

Lol. Yes zombies. Haha
Idk I've always gotten approximately 17-18 mpg on hiway but this time 13.65 mpg was about it. Ugh!
Yea I get that the H3 is a brick haha but this was a big hit to the nutz.

^^ 13-15 is normal.

 

[Happy Hummer]

17-18 is my normal.

From what I understand a Roof Rack Device suffers the most MPG and why I won't buy one and saving 2/3 MPG to me is worth it ....

I just bought a rola rack. Can't wait for it to come in!

When one buys a Hummer or any 4x4 especially with modifications, good gas mileage is non prevalent. Its all about functionality, reliability and looks.

I have had mine for going on 3 years now. I live in Michigan, so I touch up the paint every spring to keep the rust from destroying it... I love it though. Did you get the extension with it...?

Yeah I got the extension. It looks so much better in my opinion with the extension

I don't understand this Roof Rack hype? The H3 has enough cabin room. I think it's a waste of $.

Try fitting 3 38's in the truck like I did yesterday and your opinion will change quickly haha

I will agree that there is enough cabin space...for 2 people haha. If you have 4 people and their stuff, good luck. I know mine came in very handy when 3 of my friends and I went to Florida and took my car. The trunk was stuffed full and so was the roof rack. I also like it because its a place to put things you do not want in the cabin.

Yeah the Trunk really isn't all that big. Completely filled it with beach stuff for a day trip once.

A rack is a huge drag at highway speeds, loaded or not. An empty rack is like throwing a buck out the window every 20 minutes.

 

[rsc]

On trips I get better better mpg and space taking one of the other cars in the garage, but if I want to take the Hummer wheeling in another state with the family for the weekend, a Kia won't cut it. Neither does the limited space in the back. Thats when I need the roof rack or a hitch mounted basket. 4-5 people and stuff is maxing out the H3 just on day trips, gotta have a way to carry the extra gear for a long weekend trip or camping.

Yeah, but they look really cool! [emoji12]

I commute 25 miles every weekend to school and back to home with my rack and I have no care in the world that it's like dragging a bag of bricks attached to my large brick wall of a car.

It's a hummer, it's not meant to be practical hahah.
