Real world gas mileage for sedans



  • philmophilmo Posts: 77
    2002 S60
    57,000 miles
    5 cyl. low-pressure turbo

    Combined mountain road and city driving, 27 mpg
    Highways/freeways, 33 mpg

    Per the saleman's recommendation we run mid-grade with no adverse affects since we live and drive between 5,000 and 10,000 ft. asl.

    This car seems to be hitting it's stride now that it's over 50,000 miles -- an awesome road trip car at a sweet spot for performance, style, safety and economy for a two-person family. We also own a Grand Cherokee but the Volvo is the car of choice when we go skiing thanks to the split-folding rear seat, power and low center of gravity.
  • Just purchased an Avalon XLS (2007)...could anyone with experience please tell how it will "optimally" better perform using 91 octane? Better acceleration? Better fuel economy? and so on? Thanks

    There are two messages on your computer display board. One is your average mile per hour and the other is your miles per gallon. I only have about 700 miles on my '06 TL and my mpg is only 21. I do suburban driving. Highway... at 55-75/hour and around town. I'm very disappointed by my mpg. Want to hear about other TL users. Maybe this is a post for the Acura board only? (No offense you Avalon drivers.)
  • I drove my VW Passat 3.6L from El Paso to San Antonio with my cruise set at 86. By the way, I got 30.4 mpg on that leg of my trip.

    The mpg displayed on TL are cumulative. The mpg should improve after the break-in, so reset the trip computer and enjoy :) .
    FYI, my '06 TL gets ~16mpg in stop/go, and ~30 @65 hwy. On average I get 22, but I reset the computer after each fillup.

    43k on my 05 Av Touring, although I generally put the good stuff in it because I do feel a power difference, have not noticed any falloff in FE running regular - which it does just fine. 27 mpg overall basically from day 1 - 70% or so highway. Enjoy your Av!

    I guess my heavy traffic commute really hurts my MPG. My '06 Avalon XLS has never gotten a tank average over 21.5. On some longer drives have seen the MPG creep up to 25 - 26 but by the end of the tank its back down to my normal 19.8 - 20. I am not complaining, mileage is still good for a car this big and powerful, but I just don't do enough open highway cruising to see mileage well into the 20s.

    i can certainly understand only seeing 21 mpg if you don't get the car out and let it stretch its legs. Where I live (Texas) roads are billiard table flat and they do tend to move most of the time. Under these conditions at about 75-80mph, I will see an incremental 28-29 mpg, off highway stuff at 21 or 22 (which is generally not a whole lot of gridlock) is what gets my average down. Have a friend with similar driving habits that owns a 300C - he is lucky to see 12 or 13 around town, claims a whole 22 or so on the highway, 16 overall. But, he is slightly faster than I am, what a price to pay (11 mpg)for a half second or so to 60?

    Lot of extra weight in the 300. Tons of power too, but all that combined really adds up to dismal fuel economy. The 300 definately has some appeal though, I see a lot more of them here in Jersey than my Avalon.

    IMO, the 300C is a good example of what a 'Detriot' car ought to be - big, RWD, a real rear suspension, and a big torquey V8. MPG will suffer, of course, but 'Detriot' has never shown any ability (or inclination) to build a good higher HP V6 that is also efficient. Look forward to GM getting in on this with the Australian Holden, possibly with a Vette derivative V8 at 350 hp or so as both Chrysler and Chevy leave Ford behind.

    Just drove my 2006 VW Passat 3.6L from Indy to Philly & back (1300 miles) at the speed limit plus 5. Got 32.3 mpg for the trip.

    Averaging 39 overall which is excellent for mostly city driving. 48mpg on the hilly expressways around western PA & 52 when I'm on the expressways in the flatlands.

    Try this discussion: Toyota Yaris Real-World MPG.

    You should have a look at entire Yaris group. Looks like you've found a couple of the discussions there, but you'll probably see some others that will be helpful as well.

    Keep one thing in mind, though - people who are interested in any particular vehicle tend to read all of the discussions about it. So it's not necessary to post the same question in multiple places.

    Good luck on making your decision.

    Hard to believe that simply adjusting your driving habbit dictated by feedbacks from scan gauge can improve fuel efficiency that much. It did to me and now I have scan gauge in all my 3 cars.

    Although not by 25%, trip computer has certainly helped, in my TL. My typical driving involves 50-50 city/highway split. The worst tank ever (calculated and indicated) was at 23 mpg. The norm had been 24 mpg. This is with lead-footed driving.

    I started to note that by being light footed (but not slow), I could get 32-33 mpg going about 72 mph. I did notice that lead-footed starts didn’t impact fuel economy as much as accelerating and braking too much. That led to learning a way to now average 26 mpg on a consistent basis under the same driving conditions. I’m actually disappointed if my trip computer shows 25 mpg at any point. Calculate mileage has consistently been 25.5-26.2 mpg since my discovery.

    If not for virtually daily traffic jams, I might be able to average 27 mpg, something I have never achieved even in my four-cylinder Accord (rated 23/30 in its day, compared to 20/29 mpg for the TL). I do get 25-26 mpg in my Accord with aggressive driving (the kind that gets 24 mpg in the TL).

    This started when I got a TSX for loaner. I averaged 62 mph on my drive from the Acura dealership to home, and the trip computer showed 35.7 mpg. I said to myself, “Wow” (I never got a chance to calculate mileage because I didn’t drive a full tank). And that got my learning with the TL.

    And now, I’m trying to maximize mileage while also trying to maximizing average speed. The best number came from last road trip in my TL, 72 mph and 31 mpg. And that average speed includes some city driving and slower highway driving (60-65 mph).

    I do notice increased drop in mileage. I get about 28 mpg at 80 mph, down from 32 mpg at about 72-73 mph. Another discovery: The best mileage happens with speed ranging from 40-45 mph to 70-75 mph.
  • robertsmxrobertsmx Posts: 5,525
    Today, I decided to play a little to see what kind of mileage I can get in my 2006 TL by keeping speed strictly between 60 and 65 mph. I was expecting 32-33 mpg, but was shocked to see trip computer report 36 mpg after ten miles (it was flirting with 37 mpg at times). The terrain was relatively flat (minor hills) and calm weather (almost no wind).

    I hope to get a chance this weekend to see if the same holds true over a longer distance. And will try to carry my camera to take a picture of the trip computer to post here.
  • dudleyrdudleyr Posts: 3,469
    I believe 37 for a TL. My 2007 I4 Accord stick got 43.8 mpg over a 520 mile trip going 60 mph.

    Lowering your speed is the key to better mpg :)

    and less money to terrorists. :surprise:

    Indeed. Observations in my TL...
    60-65 mph: 36 mpg
    70-75 mph: 32 mpg
    75-80 mph: 28 mpg

    Mileage drops rather quickly above 75 mph.
  • I'm 57 and don't drive very hard, but even I was surprised how much better my mpg became when I slowed taking off from stoplights. Using very steady gas pedal, I improved by 2-3 mpg. I found out a very long time ago that acceleration can be very successful with extremely little push on the pedal.

    2007, Automatic. 60hwy/40city.

    Get almost exactly 20MPG every tank
