  • Do you normally leave you AC on? Curious if those numbers are mostly with AC on or off.

    I just got back from a 3000 mile road trip through the Rocky Mountains and Pacific Northwest. Terrain was varied (up and down mountains, winding coastal roads, 80mph freeways, etc.), but very little city driving. I averaged 24mpg for the whole trip. A couple of times, I got 27mpg (average for a full tank). I never got less than 21mpg (for a full tank).

    People that are getting 15mpg must be doing lots of cold starts and stop-and-go driving. No gasoline engine is efficient in those situations (though maybe electric might be). I think the RDX's MPG is great (for a 2 ton vehicle) on the open road.

    Does anyone live in Manhatton, NY and have the actual MPG want to share? Or any people only use the RDX for city use only and have the actual MPG. I travel a lot in NY City and want to know the MPG before buying it, thanks.

    If Downtown Chicago (Water Tower Place) works, we average about 20.5 in mixed driving.
  • I just bought my RDX three months ago, I only do city driving in downtown Chicago. I was more than disapointed to learn my average MPG is 10.4. However, this has been during some of the worst continuously hot weather we have seen in years, so the AC is always on. I would not say that I drive crazy fast, just trying to keep up with traffic. Other than the low MPG, i love the car, much better than my 03 discovery

    WOW. You either need to take that thing in for service immediately, or find a new way of calculating MPG. Even Hummer owners who race off-road would balk at 10.4. :surprise:
  • 10.4 is the lowest I've heard... must be computer error or you are doing wrong maths.
  • After drive my 08 RDX w/tech for one week with 143miles (delivery with 4 miles). just refill the full tank with 9.11 gal

    143/9.11 = 15.7mpg (Trip Computer Show 15.8mpg)

    Location, 95% local drive 5% highway in the Bay area CA.

    I drive it very easy and slow since it's still breaking in..... but 15.7 doesn't sounds good. what do you think ?
  • I bought my RDX a month ago and already got 3K miles on it (sounds like a greyhound).

    80% highway and 20% city in varied terrain of pacific northwest. I think 20mpg is probably the average depends on the driving habit. I don't hammer the gas and use cruise control on highway. And open window/roof instead of AC in local.
  • Just returned from a 3 day trip from Irvine, CA to Paso Robles, CA and back. Got 20.8 mpg overall which was about 80% highway/interstate. About 10% was on narrow, hilly roads connecting the various vineyards in Paso. At home I'm getting 17+ mpg in suburban driving. The car is only about 3 weeks old and had about 500 mi at the start of the trip. My only complaint so far is that the tires generate considerable cabin noise, especially on concrete highways. The noise seems to interfere with the voice recognition system.

    We've had an RDX three times when one of our cars was in the shop. We were surprised the mileage was so low the first time we had one so the next time we did an experiment. We filled it up, reset the mileage and drove it conservatively like we do our TLs. Then we filled it up again and drove it fairly aggressively. Then we filled it up again and drove it on the highway. Each drive was at least 20 miles, which was plenty of time to get a stabilized reading. Our results (as displayed by the computer) were 19 mpg city driving very conservatively (almost never letting the turbo kick in), 15 mpg driving aggressively, and a very surprising 23 mpg highway at only 65 mph. Actual computed mileage (miles / gallons) was slightly lower, 5-10%. When we reported this to the dealer they said the reason was "we always put regular in our loaners, you'll get much better mileage with premium". Then we told them we specifically got a loaner that was near empty and filled it up with premium so we could see what the best mileage the RDX could deliver. We definitely could tell a difference in performance and mileage compared to the prior loaners so the premium did make a difference. With gas up over 50% and continuing to rise since we did these tests the RDX is out of the running now for replacing our 1999 TL due to unacceptable mileage.

    Additional Wife /MPG report. She now has 11700 miles on her 2007 RDX recently switched to regular, about 500 miles ago. Mileage at 23 mpg, computed by hand. I do the calculations myself as I fill it up. I wish I could get that kind of mileage.
  • I'm getting very poor results on the RDX. With conservative driving (minimal turbo kicking in) I'm getting about 14.8mpg. With more aggressive driving and turbo kicking in more often its 10.8-11.4 mpg. This is a 4 cylinder car, not a hummer or escalade! Every time I look at the gas gauge I cant believe how quickly it goes. I only do city driving, so it is all stop & go, and short trips. But I never got above 15mpg. :mad:
  • johnny98johnny98 Posts: 88
    15mpg with minimal use of the turbo is really terrible. Is this on the highway or on stop-and-go city streets? I regularly get 24mpg or more on long distance highway trips. Half-city and half-highway is around 20mpg. If you're getting much less than 20mph on the highway, I would get the car checked out. Obviously, you're going to get much lower gas mileage at slow speeds with lots of cold starts.

    Driving an '07 RDX with about 8K miles. Trip through NY, PA, MD with a lot of highway but with a fair amount small speed-trap towns and 2-lane roads and hills. Driving mainly gently with a lot of cruise control, but I'm not a hypermiler and I'm willing to spool up the turbo to climb hills and pass dunces.

    Result" I got 25+ out of the first tank and 26.5 out of the second. Pumping the tires to about 40psi was the only thing I really did for trip prep. This might be the point where I really started to love the RDX again.
  • Its all city driving, like stated, so its stop & go every couple blocks. I did take it to the dealer, and they said its "normal" to have variances between sticker and actual due to the way you drive. Of course it is, but I have an RDX and not a hummer, so these poor results are ticking me off. I wouldn't have gotten such a small SUV had I known it was such a gas guzzler. I was in my friends Mercedes ML350, and I saw her monitor display 17.9mpg. I was astonished. We drive the same places, same city driving, and she's getting much much better mileage on a 6 cylinder much heavier SUV. I got this nice turbo that is sucking me dry. If you guys would buy again, would you get the RDX due to this mileage trouble?

    We are getting 20mpg after 500 miles in 50/50 stop and go + 70mph express way driving.

    On 9/20/08 I got 24.0 mpg on a 134 mile trip from Irvine, CA to Santa Barbara at an average speed of 67 mph. Light traffic, little or no wind, 3 adults, overnight luggage, roof rack, but nothing on it. All numbers from the trip computer. This car was purchased Dec 2008 and had about 8000 mi on the odometer at the time. My only real complaint about this car is the quirky voice recognition system in the Tech package.

    I have a new 2008 RDX, base (owned for 3 weeks). It's Black/Black and shines up beautifully (using Klasse). Early mpg says 24 plus on the highway. 15 plus exclusively stop and go local driving. I expect that once it has 10,000 miles on it, mpg will be slightly better by then. Other than the not-so-great mpg, this car is fabulous, and I view the mpg as one small compromise in exchange for a great drive.

    On a recent trip between Park City, UT and Sun Valley, ID on mostly (80%) freeway at 75-80 (75 speed limit) my mileage was 23.7 by hand and 22.8 on the tech computer. I use the paddle shifters for almost all deceleration, used no A/C with windows closed and do not do any special tricks to enhance mileage. Fuel used is 91 octane.
