2012 Subaru Impreza – Click above for high-res image

Subaru is set to officially reveal the 2012 Impreza at the New York Auto Show towards the end of April. Ahead of its debut, the automaker has released a single profile shot of the four-door version of the soon-to-be released Impreza.

Subaru's extremely brief press blurb doesn't reveal much in the way of specific details on the upcoming Impreza, but it does say that the vehicle "will deliver 36 miles per gallon highway, the highest fuel economy [manufacturer's estimate] of any all-wheel drive car on sale in the United States." To put that estimate into perspective, the current 2011 Impreza, when fitted with a 2.5-liter engine and five-speed manual transmission, is officially rated at 27 mpg highway.

We're told that both the four-door and five-door versions of the 2012 Impreza will take to the stage at the 2011 NYIAS and you can bet that we'll be on the scene in New York to capture live shots of the unveilings.

      Impressive indeed. Maybe the engine is downsized to a 2-litre ?
        • 4 Years Ago
        They already have a 2.0l 150 hp Engine for the current Impreza here in Europe, so maybe it's that one.
      • 4 Years Ago
      Probably back to FWD instead of AWD.
        • 4 Years Ago
        The Lineartronic CVT is mechanically front wheel drive.
        The drive to the rear axle doesn't come from a center differential, but a transfer clutch.
        If you are a Subaru purist, then it is a center differential or nothing!
        • 4 Years Ago
        The press release actually says, "The new Impreza will deliver 36 MPG highway, the highest fuel economy* of any all-wheel drive car on sale in the United States..."

        So it will be (based on their press release) all-wheel drive.

        Sounds interesting...

      I am with Dave. Hopefully it gets a 6spd MT with a very tall top gear so it can equal CVT highway MPG.

      There is no reason a MT has to have lower fuel economy.

      Subaru has always been on my radar, but if the can bring up the fuel economy that much it gets a lot more likely for a purchase.

        • 4 Years Ago
        Ooops. I mean MikeW....
        • 4 Years Ago
        Arguing with yourself, Dave? Because that didn't make a lot of sense.

        The main issue for highway fuel economy is the ratio. Put the same top gear in a MT and it would do as well if not better (less losses in MT than a CVT even).

        It seems that every manufacturer is scared to Give MT a fair shake except GM...

        The real issue in the case of Subaru is that the MT has real AWD and the CVT is FWD with slip-catch.
        • 4 Years Ago
        "would be un-driveable (or at least unbearable) 5,11,17,23,29,35 mph per 1K"

        It doesn't have to match exactly,it just has to get close. The transmission could have the same gear ratio as a typical 5 speed in the first 5, with a very tall 6th beyond that. Also gear spacing doesn't have to be identical ratios. 6th can be a bigger jump that you only use when you are highway cruising.


        Should be very drive-able and will give you 1800 RPM at 60 MPH. At some point even the CVT will to no real additional benefit going to a taller ratio. You aren't going to idle down the highway.
        • 4 Years Ago
        There is no frickin way a 6 speed stick is going to match the CVT.

        Yes there is. The powertrain controller knows how to adjust the throttle, camshaft phaser settings, CVT variator ratio to get optimum mileage, and remain emissions compliant.

        The top gear of the Lineartronic CVT is probably 35mph per 1K.
        I suspect/hope Subaru will offer this engine with a 6 speed stick (maybe not in the US) Top gear will probably be 25mph per 1K.
        25/36 CVT, 26/31 6 manual are probably good bets on mileage.
        • 4 Years Ago
        Yes, I hope Subaru offers the fb20 engine with a 6 speed manual transmission, because some people want a small engined vehicle with four wheel drive, not front wheel drive with a PTO system. (and the whole slow car fast > fast car slow thing)

        Yes, Subaru's manual transmission has 2.5 gear meshes (1.5 helical spur, 1 hypoid ring/pinion) from crank to axle [there is an extra gear mesh to move the rear axle output of the center differential back up to driveshaft height-just so in can angle back down to the rear differential], which is less than the Lineartronic CVT, which has 3 helical spur, 1 hypoid ring/pinion.
        But the fuel economy test doesn't work that way. Small engined vehicles can not stay with the speed/time trace so they end up penalized on the window sticker, but in the real world such arbitrary constraints of speed vs. time are not imposed.

        Plus a 6 speed stick matching the Lineartronic would be un-driveable (or at least unbearable) 5,11,17,23,29,35 mph per 1K, who would want a top speed in 4th gear?
        I'd like 4,8,12,16,20,24 for the FB20 & 5,9,13,17,21,25 for FB25.

      My wife averages 30 with her 5-speed Impreza Wagon, well over the EPA estimates. If she could beat these figures by the same percentage she'd be getting 40.
      I tell her she doesn't need AWD in Arizona, but hey, we got snow today in April (Flagstaff got a foot), so you never know.
      • 4 Years Ago
      36 mpg is indeed a huge jump for the Impreza - and just in time. I expect that this fuel economy will be with the CVT - I wonder if Subaru will sell it with the 6MT instead of the 5MT?

      Right now the most efficient Subaru is the Legacy with the CVT rated at 23/31. The 6MT is rated 19/27.

      Combine the smaller engine with the smaller car and a few other improvements and it's not a stretch to see the Impreza getting 36 mpg on the highway. I'd expect to see the city fuel economy rated around 25-26 mpg.
        • 4 Years Ago
        146, 170, whatever. I'm a huge fan of going fast, but I'll trade 24 hp for 9 mpg any day; especially since 170 is nothing to write home about in the first place. Hopefully it has more than your reported 146, but if it doesn't, I'm not concerned. The #1 reason I have never been interested in Subaru was their horrendous fuel economy. 36 mpg is a good step in the right direction for a company that touts its environmental friendly-ness.
        • 4 Years Ago
        With a reported 146 hp / 109kW, thanks but no thanks, Subaru.

        P.S. The current one is 170 hp, IIRC.
      • 4 Years Ago
      That's a huge 33% improvement. Way to go, Subaru!
        • 4 Years Ago
        Hmm, different test methodologies.
        Here are the European tests:
        'Urban cycle
        The urban test cycle is carried out in a laboratory at an ambient temperature of 20°C to 30°C on a rolling road from a cold start; ie, the engine has not run for several hours. The cycle consists of a series of accelerations, steady-speed driving, decelerating and idling. The maximum speed is 50 km/h, the average speed is 19 km/h and the distance covered is four km. The urban cycle is repeated four times.

        Extra-urban cycle
        This cycle is conducted immediately after the urban cycle, and consists of about half steady-speed driving and the rest accelerations, decelerations and some idling. The maximum speed is 120 km/h, average speed is 63 km/h and the distance covered is seven km.

        Combined fuel consumption figure
        The results of the urban and extra-urban cycles are combined and presented as the final figure. This is arrived at by averaging the two parts of the test and weighting them by the distances covered in each part.'

        • 4 Years Ago
        @kl You are neglecting the fact that the Impreza is AWD and the compact cars you're benchmarking against are not. Take that into consideration and 36 mpg is impressive.
        • 4 Years Ago
        As per Wikipedia and cross-referenced from other sources:

        --------------The "highway" program or Highway Fuel Economy Driving Schedule (HWFET) is defined in 40 C.F.R. 600 App I and uses a warmed-up engine and makes no stops, averaging 48 mph (77 km/h) with a top speed of 60 mph (97 km/h) over a 10 mile (16 km) distance. The measurements are then adjusted downward by 10% (city) and 22% (highway) to more accurately reflect real-world results. A weight average of city (55%) and highway (45%) fuel economies is used to determine the guzzler tax.--------------

        I find nothing impressive about obtaining 36MPG over 10 miles using a warmed up engine and shifting speeds a mere 12 MPH.

        It's halfway through 2011...they need to do FAR better than that.

        • 4 Years Ago
        What on earth makes you think it is at steady speed? Tests typically have an urban cycle, and a highway cycle, both of which involve a great deal more than steady speed cruising.
        • 4 Years Ago
        No it's not impressive. 36mpg on this car is pathetic given that they had to lose 30 HP to do it.

        Big whoop....what the hell is everyone celebrating about????

        Getting 36 MPG on the hwy at steady speed with the engine using maybe 10-15% of its potential is pathetic.
        • 4 Years Ago
        With those 36 mpg they now have at least a "close to average" value for a compact car - but as about everybody has either a hybrid or a diesel in this class, they need another version with these 36 mpg _average_...
      • 4 Years Ago
      The diesel? A hybrid? A 1600 cc engine with rejiggered turbo like the upcoming crop of American cars and the European VW TSI engines?
      • 4 Years Ago
      should go without saying, it's not green.
      wont help peak oil nor global warming.
      speaking of peak oil, crude went to 113$ and brent oil to 125$. that's getting quite close to financial crash levels.
      there is nothing quite like the absence of 2% of the supply to crystallize how strained the oil supply is.
      big fat I told you so. but you haven't seen anything yet...
      • 4 Years Ago
      What's the city mpg?
        • 4 Years Ago
        I am going to guess:
        2.0 Lineartronic CVT 25/36
        2.0 6 speed manual 26/31
        2.5 Lineartronic CVT 24/33
        2.5 6 speed manual 25/30
        • 4 Years Ago
        Don't ask.

        Because Subaru is too embarrassed to tell.
      • 4 Years Ago
      Since the people have realized "peak oil" and "human caused global warming" are pure red herrings, I applaud Subaru for this leap forward with economy in 4 wheel drives. Dan is now an anachronism, and it's time to get back on increasing energy efficiency, instead of hand wringing over the red herrings of the left, where the anti business communist movement ended up after the fall of the USSR. You want to decrease carbon emissions, go after shipping and commercial aircraft, which are far worse in carbon emissions than ordinary citizens with autos. People need transportation, and we need not feel guilty about that.
        • 4 Years Ago
        Dan, we agree on the need for more efficient transportation. We disagree on much, but that agreement is basic. Our main disagreement is in the role of government. I am a free market capitalist, and you believe the government should control everything. There are obvious drawbacks to each philosophy. Peak oil will be a non event. History has proven it. Humans contribute less than one percent of greenhouse gases. Research it yourself. The fact is we are incapable of moderating climate change. The climate has always changed and we have always had to adapt. We need to move forward. We don't need red herrings to scare people to action. Everyone benefits from cleaner environments and technological advance. We both are impatient for the transition to alternate sources of energy. We both detest corruption in government. What we are witnessing is an historical rapid transition from the oil economy to more modern technologies, but it won't happen overnight. You are a thoughtful guy, and among those on the left, you seem uniquely capable of some original thought. I respect you, but you are very impatient. I still always want to hear what you have to say.
        • 4 Years Ago
        guilt free is what I am suggesting. but you can't be guilt free and thoughtless at the same time. frankly, it's my way or the highway. and you wont like where that highway ends.
        you can blame me for the truth but you can't be right that way.
