    Having driven my friend's Sienna extensively, I'm quite sure it wouldn't.

    I saw an article recently where they pointed out that the new Legacy with the CVT has notably better fuel economy than the Accord 4-cylinder with automatic. That's impressive to me, but I sure do wish they would bring these improvements (including the new 6-speed manual) to the Impreza line ASAP.

    I may be using hyperbole, but compared to the Forester that's how it feels.

    Yes, for sure, let's see a CVT Forester and Impreza.

    AND 6 speed manuals with that nice tall, economical, highway cruising gear!

    Most 6-speeds I see have the same gear for 6th, that the old transmission had for 5th... :(

    My Miata's 6th is actually shorter than 5th on the 5 speed manual models.

    Mazda gears them too close, if you ask me. I need a 7th gear.

    two more tanks now, both around 27 mpg, so I guess I'm just going to have to live with it. I was really hoping for 30, so my gas bill is 10% higher than I would have liked, but that only amounts to $10, maybe $12, a month so it's no biggie....I will miss the bragging rights more. :-|

    It uses 1/3 more gas than the Matrix did that it replaced, but it's at least twice the car in every other way, so it seems like a fair shake! :-)

    30.3 mpg on my last tank.. haven't been under 29 for the last four months, at least....

    But... I've been driving to get high mileage... If I just drove it, and didn't pay attention to it, I think I'd be down around 27...

    It was only rated for 20/27, so I'm pretty happy.... and the vehicle it replaced only averaged 23-24 mpg...

    I am on my first trip of any length in it this weekend, and am pleased to note that for highway trips, at least, I can easily get over 30, seems to be about 31 mpg if I apply the standard method of subtracting 1.5 mpg from the dash readout to come up with true mpg (is always confirmed by gallons/miles calculations at fill-up).

    And that is without babying it, up over Donner Pass at 70-mph-plus with A/C running the whole way. And the extra power at highway speeds vs my Matrix is VERY welcome on that trip!

    So...two tanks of gas for the whole trip, total of about 700 miles, one tank was 31 mpg and the other was 30 right on the nose. Not outstanding, but acceptable and not far off what I expected when I bought the car.

    You rogue!!

    I know now I will never top 28 mpg in normal driving (and yes, that was once again the mileage reading on my last tank of gas, filled up on Wednesday).

    I have made peace with it, although this will definitely be my last Subaru in this lifetime if they don't improve the lousy mileage.

    Had my friend's '04 Accord for a couple of weeks, automatic instead of stick, more power, more weight, yet I managed 33 mpg in that car effortlessly, doing exactly the same driving that only nets me 28 mpg in my 5-speed OBS....

    The newer automatics have a much lower final drive ratio than our sticks.. They are loafing at 2400 RPM at 70 mph... You can't match that...

    Considering the power, AWD, and the relative inefficiency of the manual at cruising speeds (compared to the auto), I'm pretty happy with my mileage..

    After all, mine was EPA-rated at 20/27... :surprise:

    I'm doing a lot of coasting, though..(hilly area, here). I'll have to cut that out, come January, when I'm teaching my son to drive.. Can't enforce any bad habits...

    All that said.... Did I mention the 31.5 mpg on my last tank? ;)

    Well, I averaged more than 28 mpg (running average was 29-30) with my '97 OBS, and that car was made TWELVE YEARS before the one I have now. In all that time, this model's fuel economy has only gone down, instead of up like with most other makes and models. :sick:

    The big improvement came with the CVT on the 2010 Legacy - 31 mpg highway EPA, better than that Accord.

    The Impreza is lighter so imagine one with that drivetrain... :shades:

    No CVT for me.... I'll take my slushboxes with gears...

    That certainly was my feeling when I drove the 2010 Forester and CVT 2.5i Outback sequentially. However, the sloppy handling of the Outback added to the problem of its excessive noise. The 3.6 Outback which I drove first was nice other than for the soon-to-be broken-off mirrors.
  • ateixeiraateixeira Posts: 72,587
    The CVT is more efficient than even the 6 speed manual, though.

    I wonder how they will do in the real-world. I'll ask around when enough are sold that we have a good sized sample.
  • nippononlynippononly SF Bay AreaPosts: 12,726
    is my latest single tank reading - filled up today. After my disappointing results recently, I decided what the hey, I would stop focusing so much on saving gas and start having more fun with the car (!!), and I was surprised to find that the fuel economy reading dropped very little.

    For the first 5000 miles I have averaged 28 mpg right on the nose.

    '09 OBS 5-speed.

    My wife needed gas so she asked me to take her Forester on an errand. She was averaging 23.something in around-town driving (to be fair she takes short trips) but I decided I would try to maximize the efficiency as best I could, i.e. hyper-miling.

    It was pretty amazing - in all suburban driving, on a busy Saturday, middle of the day, I managed 29.7 mpg. With traffic.

    Definitely had to go slow, coasted to all the red lights, etc. But I was pretty impressed. I didn't take the highway once.

    YMMV is as true as ever. You'll get anywhere from 23 to 30 mpg in the 'burbs depending upon how you drive, and the length of your trips. Warm ups kill mileage.
  • nippononlynippononly SF Bay AreaPosts: 12,726
    Yeah, and all my miles are in the burbs, so pulling 28ish isn't too bad, I had just hoped to make the 30 mpg "cut".

    Interestingly, I completely ignored fuel-saving techniques in 200 miles of driving this weekend, because I ended up running late more than once, and despite that the dashboard readout said 30.0 when I got home! That would translate to a real-world 28.5, among my best results in this car. So I don't get it.

    I haven't been driving it all that much, 800-1000 miles a month, which is only 2 fill-ups per month, and I am wondering if I am losing enough to evaporation while it is parked that it is bringing my average down....

    If you drove a lot, the engine probably stayed warm the entire time.

    Those warm ups kill ya.
  • xwesxxwesx Fairbanks, AlaskaPosts: 10,920
    Yes, they do!

    I must say that, thus far, I love the PZEV on my car! Not only does the car warm up astoundingly fast (probably close to half of the warm-up time of previous Subaru vehicles), but it also burns very clean. So much so, in fact, that the other night when I had it in a shop to winterize it, I could not smell any exhaust at all after backing it into the space and letting it run for a minute or so. Now, if there is CO in there, that is not necessarily a good thing, but it sure gave the impression of clean. :D

    The only down side that I can tell so far is that it idles very strangely during warm up.

    Meh, it's probably cleaner than the air around us. ;)

    Yeah, I noticed that too, it stumbles quite a bit and is generally fairly funky to drive when it's cold. But since my old Subaru did that too even when it was new, I just figure it's one more Subaru "quirk", and if it is somehow contributing to the ultra-fast warm-up this car does, I am all for it! :-)

    Days off work really kill my mileage... I generally get 10-12 days between fill-ups... I had five days off in the last cycle.. Those local errand runs really knock it down..

    My best tanks come when I only have one weekend in the cycle..

    Lower mileage is a small price to pay for days off, though.. ;)

    Hey, you should be grateful for 28.6! That is as high as I am ever going to get, except for all-highway tanks, it would seem.

    My mileage is very consistent, every tank is in the 27-28.5 range.

    today's fill-up was 11.75 gallons, 328 miles, for an average of 27.9 mpg. To make myself feel a little better, I am going to call that one a 28! :-P

    That's nothing, Stuart! My wife now drives our Forester almost exclusively. Here's the last fill: 9.2 gallons over 198 miles. :mad:

    Whoa, 22 mpg? Now I feel a little better, thanks! :-)
