http://www.motorhome.com/rv-reviews/motorhome-reviews/thor-a-c-e-road-test/Hi, I saw this review and was amazed by the poor MPG on a small class A. It does not seem to make any difference if the RV is small or big.It shows 7.1 MPG, gees, my nephew drives a 45 ft. semi and he gets a bonus when he averages over 6.2, he gets the bonus every time.I think it is too bad that there is no competition in Class A Gaz Engine now, no effort is made by Ford to reduce MPG, people just take it for granted, there no other choice anyway. I would take a little less power for a little more MPG.I am shopping for a class A, but the MPG is a killer, especially that I put on around 20,000 miles a year.

Yep. You are pushing a brick through the wind. The front profile is to blame asmuch as anything else.

You could take a Prius and have Jeff Michaels "Pimp" it out for you...best of both worlds and you'd be the only one out there driving a coach that looked like an egg....:BI average 8 mpg with my coach @62 mph, py\ut about 25-30k / yr and am satisfied with that...I don;t mind paying for comfort and convenience....Dennid

What did you expect, RVs aren't exactly light and aerodynamic. Thats actually good mileage for a V10 C-class.

I would not mind paying if I had some share with the oil industry! I just say that they could come up with a more efficient engine in a small RV, like they do in Europe.I remember a few years ago, my 2002, 2 cycle snowmobile was sucking around 6 MPG. Then came the 4 cycle engine, I bought a 2008 and was doing around 15 MPG. Then pure magic, in a short time, they came up with a much more Horse power 2 cycle engine and now get around 16 to 18 MPG with a 2009 SkiDoo. Except for a better ride comfort and performance, no big weight difference between the 3 models with weight, wind resistance, track or skis. They did it when they where pushed by the new antipolution rules. I am sure they could do better but they will not until they loose money or they loose the market.

We get about 9 mpg with our ACE 29.1.

My old 1991 Ford 460 gets 7-7.5 mpg. It has consistently gotten the same mpg since new. I would think the report has flawed results.

Yes, like one guy told me, when you bring your appartment on the road, MPG is not your friend!

I guess I was hoping for a better MPG with a smaller RV.

You have to remember that a motor home is like a brick flying through the air. Wind direction/speed and speed can really whack the gas mileage. Over the years our early model 2 valve V10 with the Banks intake/exhaust has given about 7mpg overall. That's better than the 5mpg our previous motor home with the Ford 460 delivered.

You are complaining about poor gas mileage and then say you would like Ford to reduce MPG?
Keep in mind that they are talking US gallon. 3.78L makes a US Gallon and your gallon is 25% larger so use Canadian gallons and the MPG will take a 25% jump.

Had a 2011 Ext cab 2500 Chevy 4X4 with the 6.0 and 4.10 gears With our TT @ 8K or so I got 7.5 @ 62MPH on a good day. 6.7 Ram gave me 10 MPG. 6.6 Duramax gave 9.4. Don't know what my Ecoboost will give. It is what it is or will be. JMHO

Buy an egg. Keep it on the gas pedal and don't break it.

You didn't mention your price point. There are a few entry level DP's (Palazzo, Excursion, etc) that tout 10-14 MPG. But you're looking at $140k to start.

Buy a hybrid or "plug in" electric car and stay in motels or a tent. :E

I get your point, better aerodynamic = a longer MH. We see some newer, smaller MH with more arerodynamic shape coupled with a Diesel engine, but prices are much higher than the entry level MH and they do not have the room you get in a standard, flat nose MH.

You can buy a lot of gas (petrol) with the cost (purchase price) savings from a entry level Class A versus a FRED. :W

I have a 2014 Thor ACE 30.1. If I drive around 62 or 63 mph I get 8.5 mpg if I bump it up to 65 to 70 it goes down to just over 7 mpg. So speed does have a lot to do with mpg.
