Honda Civic Si Coupe Concept – Click above for high-res image gallery

Honda gave us a preview of its 2012 Civic at this year's Detroit Auto Show, and while the car we saw on stage was technically a "concept," we expect the production car to look very similar, albeit with more conventional wheels, headlamps, and, you know, an interior. Instead of just showing one Civic, Honda brought out both a sedan and Si coupe concept, and now our friends at Temple of VTEC have reportedly confirmed that a new 2.4-liter mill is on deck for the sportiest of Civics.

Known internally as "K24," the 2.4-liter engine slated for Civic Si use will be very similar to the powerplant currently used in the Acura TSX. No official power numbers have been divulged, but this engine currently makes 201 horsepower in the TSX, so we'll bet that Civic Si output will be somewhere between 200 and 210 hp. That isn't a huge increase over the 197 hp currently available from the Si's 2.0-liter four, but the 2.4-liter engine should prove to be a bit torquier. Look for something along the lines of 170 pound-feet in the 2012 model, whereas the current car only produces 139 lb-ft of twist.

Official data will be revealed closer to the Civic family's launch later this year. And while these new Si numbers aren't leaps and bounds better than what's currently available, the easily flickable driving dynamics and rev-happy power should still make it an engaging steer.

      SMART MOVE!!!!

      The k24 should have been in this car all along.
      The added torque will make this car so much more driveable.

      Finally a move from Honda that actually makes some sense!!
      • 3 Years Ago
      AHEM, excuse me. Is Autoblog filled with nothing but drag racers these days?

      Let's see how this thing handles. It's no championship winning car, but if it's easy to handle on a track, I think the Si has achieved its goals (a sporty car for newbie track enthusiasts).

      And people clamoring for 270-300HP in their Civic Si... are you nuts? Have you forgotten what torque steer is?
      • 3 Years Ago
      Curious, why does the Golf GTI get the pass while this new Civic Si does not? The GTI also only has around 200-210 horsepower, and this new Civic will have _at least_ 200hp (the actual performance figures haven't even not been released yet people). The Si will also probably weigh less and return similar or better mpgs, and cost less to boot. So whats the deal?

        Are you new to Autoblog. It doesn't matter what Honda put under the hood. All the honda haters on here would just hate.

        It could be a normally aspirated 2.0 as before with 500hp, and they would all hate on it. That's how things go here at Autoblog.

        What's even funnier to me is that sport compacts are no longer the sole choice for credible sub-$30k performance. Unless you also need utility, Mustang and Camaro outpowers and outruns most, if not all in every tier of the sport compact segment for similar money.
      • 3 Years Ago
      That extra 30-some lb-ft of torque should really help the new Si get off the line quicker. Even if it doesn't gain much horsepower, it should be noticeably faster--as long as they keep the weight in check.
      • 3 Years Ago
      Not to be realistic or anything, but the kind of enthusiasts who actually care about VTEC on the exhaust side do not pay the bills at Honda. The extra 500 sales they'd get by catering to car-crazy, pizza-delivery guys just doesn't justify the added expense. And be fair, most of the complainers weren't going to buy a Civic, regardless of what engine it got.

      It's like the tired, old scenario in nearly every car review. Regardless of the vehicle's intent, the tester thinks it needs stiffer suspension, grippier tires, and at least a hundred more horsepower. We get it, already.

      Ok, despite all the whining above, I think this actually sounds pretty good. That's a healthy bump in torque, which is the current model's weakness. If they can keep the price point and fuel efficiency the same, sounds like a good change.
      • 3 Years Ago
      For the people who doesent know anything about Honda... Type R its SOOOOO much diferent besides Si
      Type R its almost a racing car and the Si its like a golf gti ...besides both models dont rev up the same
      ...I`ll wait for J`s and Spoon tunne up for this K24
        • 3 Years Ago
        You doesent undarstend whut he is saying?
        I think your spelling could use a 'tunne up'.

      People complain that Honda's have no torque, they decide to put an engine in with some torque and everyone complains again.
        • 3 Years Ago
        @loosewheel26
        Have you met the Mazda speed 3 ?

        Turbo 250 + hp and 280 lb-ft of torque.



        So YES people are complaining about the Si n its so called "performance"
        • 3 Years Ago
        @loosewheel26
        170 is not torque. Maybe in 1995, but for 2011? I think it is time that Honda actually put real power behind its "sport-inspired" coupe.
        • 3 Years Ago
        @loosewheel26
        Why not just put the defunct S2000 motor in there?

        200hp / 170 torque in this motor or

        240hp / 170 torque in the S2000 motor.

        I'd choose S2000 motor everytime.

        It's weird that Honda seems like it's engines haven't changed since 1997. They had a 2.0 200hp motor back then. I understand it may be cleaner now but still, come on Honda!

        Hyundai has a 2.4 200hp engine and it gets 35mpg highway in a much bigger car. If they put that into an Elantra it's going to be getting 37mpg and be right with you for a much cheaper price.

        @ Mike

        Research would do you good.

        First off, the F20 and F22 were designed for RWD use. They won't fit in a FWD application.

        Second, while they made some kick ASS power and are fun to drive, the powerband isn't tractable. They aren't well suited for day to day, stuck in traffic driving. Go look at a dyno chart from a AP1 S2000.


        @ miketim1

        Can't compare N/A and F/I, you just can't.

        Honda is focusing on cleaner engines and fuel economy. The MS3 isn't that clean, and it is hard to get over 31MPG on the highway. I do have to say that the EPA sticker on the MS3 is full of crap though.

        @Mike


        ....Because the K24 is capable of 240hp, plus it will put out more torque.
      • 3 Years Ago
      Had an 06 TSX w/ the 6 spd manual. The K24 was uninspiring to drive except for the 600-800 rpm of ivtec before redline. If Honda wants to really compete with the other sport compacts in the segment they should really just look in the acura RDX parts bin. Unless they can miraculously take off some weight to offset the addition of the K24.
        • 3 Years Ago
        600-800RPM? Try 2,200+ RPM where it was on the hotter lobes.

        The Si really should have had the K23 though.
        • 3 Years Ago
        Pretty sure he meant 600-800 RPM BELOW the redline, not 600-800 RPM specific.
      • 3 Years Ago
      1991 Called, they want their 4 cylinder back.
        • 3 Years Ago
        1991?

        Show me another N/A engine from 1991 that is anywhere near what the K24, or K series in general is capable of.

        I know it isn't a Chrysler, so you feel the need to automatically have to bash it. Stop trolling please.
        • 3 Years Ago
        @ ricerXS

        ....that engine was installed in a super limited production vehicle.

        The K24 is standard, every day Honda technology that goes into THOUSANDS of their vehicles.

        Please, again, show me an engine with the same output that isn't a NVH nightmare like all of the Quad 4s were.
        • 3 Years Ago
        With the 2.4L that is turbocharged, direct injected and has MultiAir and 350HP? That one thats coming next year?

        Still funny to see nut hugging Import clowns even after the silly and pathetic import craze from years ago, isn't it.

        Honda didnt care then, and they don't care now...they were happy to take your money though.

        Line any current Honda up beside its competitors and compare the design..I could use a Laugh too
        • 3 Years Ago
        GM's 2.3l Quad 4 HO motor put out 180-190hp depending on the car. So yes, '91 wants their engine back.
        • 3 Years Ago
        1993 Honda H22 - 200hp.
        • 3 Years Ago
        Go find yourself a Chrysler 200 with a 2.4L 4-cylinder. Take it for a drive and tell us how great is. I could do with a good rofl.
        • 3 Years Ago
        The quad 4 was unreliable? I thought it was just thrashy.
        • 3 Years Ago
        I could say the same thing about pushrod engines, but I won't.
      • 3 Years Ago
      I want to be excited.... but I'm not.
      • 3 Years Ago
      While I have lost some faith in Honda Motor Co. for what they have done to the entire Acura lineup I cant quite ignore them yet. yes 200hp is weak for the next gen Civic Si but lets consider some facts:
      2011 Honda Accord EX i4 2.4L 190hp/162tq 23/34mpg 3312lbs with only a 5spd auto and it is NOT even DI. Powertrain dates back to the early-mid 2000s.
      2011 Hyundai Sonata Limited i4 2.4L 200hp/186tq 22/35mpg 3316lbs with 6spd auto and is DI. Powertrain is brand new "state of the art".

      I know we're not comparing apples to apples in regards to the Civic, but I'm just focusing on Honda's powertrain engineering abilities to the mass market. While their exterior engineers i think are on crack and cant design a decent looking car lately, you cannot ignore their ability to squeeze every bit out of their aging powertrains. Sure they're not the most powerful or fastest in their class but they can still dance in everything else.
