This Honda is a great car. The 2.4l iVTEC is an absolute BLAST to drive. The 6spd manual transmission is fantastic. While not the fastest car in this price range, I believe it's the best all-around vehicle in its class when considering price, gas mileage, reliability, 4 door practicality, and performance. I live in the midwest and weather is not always ideal. With the FWD, the car works very well as a daily driver. The new 2.4l engine offers plenty of torque and power for a vehicle in this class, but with the limited slip and stability control, torque steer is almost non-existent. In spirited mixed driving, I've averaged 28MPG. In highway driving, it's easy to get over the rated 31MPG
Having driven an Acura RSX-S for 11 years I expected a lot from my new ride. In the end, I like the 2012 Civic Si, but ultimately it doesn't feel quite complete. The TSX engine and transmission are definitely improvements, and the fuel efficiency is pretty amazing for a performance vehicle. The electronics package is adequate, but the rest of the interior is cheap and frustrating. Compared to previous Si's, the 2012 is way less juvenile, and delivers a fun smooth ride for my long daily commute.
Let me start by saying this; all my life I've driven RWD performance cars (multiple 350z 05, and 07, s2000, eclipse v6 , 08 corvette) - this was my first FWD sporty car and IT DID NOT dissapoint comparing to all of those cars, which tells you a lot. The biggest issue you will see people mention is the bad interior quality, yes if you are coming from a BMW or a Lexus it will feel bad, but coming from the cars I listed above it felt like a definite upgrade. Key Pros: MPG, Torque (yes its not a v8, but a 4cyl pumping out 170 ft lbs in a lightweight sedan (2900lbs) is superb, transmission, handling. For the price & honda reliability/resale value it CAN NOT be beat, sure there are faster cars for the same price - but you won't get the reliability or the resale (gti I am looking at you) - Should you buy it ? YES. I can't wait for the 2017 civic si.
I was hesitant to commit to the 2012 SI because the EPA estimates are not very impressive. But I took a gamble figuring if I was disappointed, I could easily trade due to the high resale value. I have just under 6000 miles on it so far in about 6 weeks. In mixed driving my worst tank of gas was 32 mpg. Best so far was over 37 (with a bit of neutral coasting at exit ramps, etc). As the car "breaks in", it really feels like it's getting quicker. It's great fun to drive. Much more torque than my '08 EXL. Interior noise is not quite, but is acceptable. My '08 interior is a bit classier. But I'm getting used to the '12.
I ordered this bad boy back in July and drove it home in mid-September. Extremely fun to drive. - I'm not going to race any Mazdaspeed3 turbo'd rockets, but this thing has a lot of pep. - The 6-speed is smooth and sweet, on par with a much more expensive BMW or Audi, but without the electrical and high maintenance issues that come with the German cars. - Sport suspension makes the road noise more pronounced but it's all worth it. It handles nicely. Anyone that complains about the road noise should buy a Buick and leave the pocket rockets to the car guys. Higher mpg than advertised - With more low-end torque, I avg 37 mpg by using 6th gear at 45 mph, even with revving up the hiway ramp.

Pokey bottom-end, so-so midrange, but lots of horsepower in the upper revs. Very quick shifts at WOT, and no manual gate to try (D, D3, etc) on the PRNDL.
Adequate first stop, then pretty dramatic though linear increase in stopping distances thereafter. Strange pedal sensation that felt almost like completely cooked brakes from first stop to last (e.g. no ABS pulse, no tire noise).
Skid pad: A novice would be hard-pressed to discover on his own that this was electric-assist power steering. Very good feel and weight that feels natural and hydraulic. Low limits are audible from squealing tires. With stability control on, you don't hear the tires, but the lap is obviously slower. Slalom: Wow, so much more body roll than I would have expected. It feels like a much larger car because it requires a lot of time to transition from one cone to the next. Still, the steering feels so good and it is so precise that it feels like the car could/should go quicker than it does -- I guess that's what the Si model is for. With ESC on, it was much more conservative and thus slower than it needs to be.
