    For a long distance highway commuter, .. I think my car is hard to beat. Especially if you like a little bit of "sporty" performance now and again. With 91 octane in the tank it really comes alive,... and you realize if you were going to drive it hard on a regular basis (I won't) you'd want softer tires and a stiffer suspension. Honda has significantly under-rated the hp/tq (as has been shown on independent dynos).
    Also, the seats/interior have proven to be comfortable and fairly quiet,definitely less fatigue on long drives compared to my gen 9 civic, and the EX infotainment works well and helps to pass the time ... (voice text with apple car play and sirius xm, siri integration)
    -- I plan to eventually install a trailer hitch for a lightweight (less than 1500 lb) trailer. This weighed heavily on my manual transmission choice as I'm just not sure how a hybrid or CVT tranny would hold up while towing.

    If my driving was mostly in dense urban, ... then the clutch could get a little monotonous. Also, I recently got to drive Toyota's Dynamic radar cruise .. I was impressed. It would be a bigger factor to consider in a heavy city commute.

    Like I said with HIGHWAY mileage like that why would you consider a hybrid. With my Prius it is the perfect car for what I use it for, short trips under five miles daily speeds 35 mph or less. The point I was trying to make is if you had to drive forty or fifty miles a day for work mostly on the open highway, a 17 Civic would be a good option.

    Are the steady state speeds down in warm weather with dry roads as cold temperature will take a hit in mpg.
    Cold weather with wet roads, rain, snow, etc. will drive you mpg down considerably. I notice a swing in our 2010 Prius, last
    fillup was 43.5 mpg calculated, winter conditions. Summer mid 50's to near 60 mpg is the norm.....

    Good news, bad news (but mostly good): This car's mpg at lower highway speeds (below 65 mph) is proving to be not as durable as the higher speed (65, 70 and faster). I think it is because at higher rpm the engine can produce enough "extra" hp for hills, gusts of wind, etc without getting into boost very far, but at lower speed (lower rpms) the engine has to lean on the turbo more (and thus drink more fuel). So good news if you like traveling above 65 mph, bad news if you don't.

    -----
    Conditions today: temps in low 40's, strong headwind 20 to 25 mph. (from memory, wished I had written it down):

    70 mph 6th gear: about 41.5
    70 mph 5th gear: about 39.5
    65 mph 6th gear: about 42
    65 mph 5th gear: about 42

    I "feel" (not scientific) that todays tough conditions probably simulated the "load" I would get towing on a normal summer day (i.e. 80 deg, light to moderate winds towing a dirt bike or riding lawnmower)

    So a big question I"ve had (still have) is what can I expect for mpg's while towing (plan on keeping it at about 65 mph)? My initial guess was somewhere between 30 and 35 mpg. If my "feel" is right, I think it could be around 40 mpg ... which would be awesome.

    5,000 (ish) mile observation:

    So far my overall mpg is averaging 43.5.
    There does appear to be some break in, as my last 6 tanks have averaged 44.6 (first 5 tanks average 42.3).

    Very much a highway car, as I usually target 70 mph but my typical highway speed ranges from 65 mph to 78 mph. If there's a tailwind blowing, I can drive 75+ mph and still get high 40's mpg.

    /once it warms up, I'll see if I can log a few 50+mpg tanks

    Hi Carcus:

    That 1.5T in your Civic sure is proving itself!

    Going a bit OT but in honor of the excellent Honda drivetrain, I have a 17 Honda CR-V w/ the hopped up 1.5T inside scheduled for mid March in Calif. I suspect it will be the most efficient CUV we have driven since the 2013 Mazda CX-5 offered the 2.0L with a stick. Unfortunately it may be a 26/32 mpgUS city/highway rated AWD variant.

    As a scoreboard, in 2014 the Audi Q5 TDI and 2015, the Rogue both pulled off low 50 mpgs on my 100+mile measured drive. I suspect the 1.5T in the 28/34 mpgUS city/highway rated 17 CR-V will become the new modern CUV benchmark.

    Hi Wayne,

    Yah the 1.5t is impressive. Honda actually under-rates the hp in the civic, as it will put out about 190 hp when you use 91 octane, .. and the tuners are programming (with no "bolt-ons") for quite a bit more than that.
    Seems like I remember reading the CR-V will get a slightly bigger turbo. Too bad Honda isn't going to put a 6 speed manual in the CR-V as there is an efficiency penalty to pay with the CVT. ... but at least they did rate the CVT for 1500 lbs towing in the CUV.

    /looking forward to your observations

    I suspect the 1.5T in the CR-V will be great for the light-footed, but the weight penalty, aerodynamics and the "typical" highway driver won't fare much better than EPA ratings.

    That's what I suspect as well. Even the sport hatchback civic pays a pretty decent highway penalty for the less aerodynamic shape and wheels. I think my 'sleek' sedan is able to stay in the NA zone and just "sips and slips" underneath the "turbo-charged penalty".

    /maybe the CR-V will have a "fuelly spread" like no other, .. lol

    Just like the Ford Ecoboost line, which should be named eco/boost. You get eco, or you get boost, but not both.

    I had the Ford Ecoboost in mind as I read the earlier posts, too... :)

    re: CR-V with 1.5T - Car and Driver (I think) puts the highway MPG at 32 for their 200 mile 75MPH test loop, 1 less than the 33 rating so pretty close to EPA rating. They rated it best in class.

    Hi Bill:

    Just a week away for our turn behind the wheel. :)

    Hi Wayne,

    I can hardly wait. I just enjoy seeing C&D set the low bar and then see what the vehicle will really do with a less frenzied pace. 32 is a very good starting point for the 1.5T.

    If I got 32 MPG with that car , I would hang myself in shame. But the C&D testing does give some indication of what the car might do when driven by concerned and committed ADULTS.

    Summertime, and the living's easy .....Last 2 tanks have been over 50 mpg.

    Wow, look at those numbers. You're turning about the same rpm as I am in top gear, but besting my Civic by a lot.

    Glad to hear AC is getting better these days. It's pretty miserable in mine for FE and doesn't work all that well. The Echo was similar in that regard.

    Yup, I was just thinking about the 2.0 EB Escape I rented last year. It was a really easy 35mpg vehicle, and that was without massive regard to technique; raised tire pressures, but was essentially CC @ 60-65 mph with AC working most of the day, plus a few dips into its power and allegedly, a traction control-off, pre-spool-the-turbo set of burnouts. Dip into the power and the IFCD dropped hard.

    Did a small flat land cruise on some rural roads in West Memphis of about 10 miles and it recorded 49mpg, probably around 46mpg actual.

    Update, .. after 7 mos. and 8,500 miles, "lifetime" average is right at 45 mpg.

    Hi Carcus:

    That result is excellent!!! As I have said before, Honda has a heck of a drivetrain pkg. under the hood of your Civic. I cannot wait to see how it performs inside the all-new 10th gen Accord too!
