    57 MPG...No Problem.

    Interesting article and comment on car manufactures and tradeoffs.
    NEW YORK (CNNMoney.com) -- Car makers are confident they can meet new government rules calling for a national fleet average of 35 miles per gallon. But it will take a big technological push, they say.

    You might wonder why, since twenty years ago the car that got the best mileage in the nation was a real techno-wimp compared to what's on the road today. It wasn't even a hybrid. But it got better fuel economy than any car sold now - even the Toyota Prius.

    Looking back at the 1987 Honda Civic CRX shows us why cars use so much more gas today and about the trade-offs we've had to make.

    The CRX HF got an Environmental Protection Agency-estimated 57 mpg gallon in highway driving. Today, the most fuel-efficient non-hybrid Civic you can buy gets an EPA-estimated 34 mpg on the highway. Even today's Honda Civic Hybrid can't match it, achieving EPA-estimated highway mileage of just 45 mpg. The Toyota Prius, today's fuel mileage champ, gets 46 mpg on the highway.

      57mpg? Might be a lil overestimated. They did it differently back in the day, I seriously doubt anyone can get that out of a CRX now. Look at the trade off. Safety , passing power, chick deflection, headlights in your rearview mirror, and hardly any power options.I think one of the best MPG vehicles i ever seen was a geo metro and Chevy Nova(corolla version). Diesels>all. I agree

        It is primarily because of increasing weight and size.

        Also, it should be noted that the EPA's measurement test standards have changed within the last year, so new numbers are no longer directly comparable with old ones.

          I used to ROUTINELY get 40MPG city out of my 1992 Civic CX hatch. And it was swapped.

          The CRX HF was probably a good 300lbs lighter, had a smaller engine, and better highway gearing.

            40 MPG city huh? I couldn't get that out of my cars highway even if I killed a cylinder. Wow..I guess i'm so use to my gas guzzlers and their shitty mileage I assume 57MPG unreal.

              Yes, I was pretty surprised myself. It wasn't a "powerful" swap, it was just a stock D16Y7 that made like 106HP, but the car weighed like 1900lbs, so it didn't take much to move it.

              It had a 10 gallon tank and I would get just about 280 miles out of 7 gallons. In the winter it was more like 36-37MPG because of all the extra warm up time.

              And it ran a 15.0 flat. I wanted to swap a D16 VTEC head onto it, to see what an extra 30HP would do, but I never got around to it.

              More than anything else, weight is the enemy of performance. Of any kind.

              Of course, it is nice to have cars that don't crumple like soda cans, and don't sound like a tin box with someone beating it with a wooden spoon...

                I guess. There are trade offs, and the large majority of people enjoy the benefits of extra weight as stated.

                  I have heard that an engine which is fed with a gasoline fume injection system can theoretically have about 100mpg as opposed to the vapor injection systems we run today.

                    There are still guys today getting +50mpg on HF's and CX engines. The older CRX HF's were like 1700lbs, so that helped out a lot. Hell, I just got ~46mpg on a cam'd D15B-VTEC 88 Civic hatchback....but I was drafting and cruising at 70mph. I'm pretty sure I would be able to get better mileage with a longer-geared transmission; I'm currently running a DOHC ZC transmission( .878:1 ratio 5th gear) and 4.25:1 EX FD and Integra steelies/tires. Cruise rpm was around 3800-4000rpm.

                      yeah i heard that too and so far i have not seen that proven yet.


                      my accord can get 38 at best on hiway only. my old civic a 92 5 door witha d15b7 in it.

                      that car ran with a lower rpm in 5th than my accord and i got like 43 mpg doing 75 constangly. so it is not hard for a crx hf get mid 50's.

                      but i still have not seen a geo with the 3 cyclinder get good mpg as the crx or the civic cx though

                        Only problem is hf's have about 60 hp and very long gears so they aren't very quick, but many people get around 50 mpg highway on them.

                        on the stairs, she grabs my arm, says whats up,
                        where you been, is something wrong?
                        i try to just smile, and say everything’s fine.

                          This goes to a friend of mine who always says that honda needs to make a limited run of EF's. say like 2000-2500. Sell them for ~$10-12k. well probably more. They would sell like hotcakes!

                          However just like it was said earlier safety would be a big issue with that small of a car.

                          I consistantly get over 35MPG with my 99 civic ex daily driver. So I'm already ready for 2020

                            "Honda Insight"

                            If you look at the specs and all, you'll see that it was built with the same concepts as the CRX. Problem is, no one wanted them so they've stopped making them. The Insight handles well, has a efficient engine, lightweight(IIRC, all-aluminum weighing in around 1800lbs), and has very good aerodynamics. I've heard of people getting around 70mpg or more on those.

                            Also, due to emissions and current regulations, I would think it'll be impossible to make/sell any of the 84-91 spec CRX's.

                              Yep you hit the nail on the head with that one!

                              I got to drive a manual insight once. neat car! it might handle well but I don't think it had double wishbone suspension. So it lost a bit of the honda sprit there

                              The one I got to drive had a manual tranny, but the gears were way too long to have any kind of "fun" in it. I don't think I ever moved out of 3rd gear. I was using 3rd the way I use fifth in my cars. infact I think 3rd was longer in the insight then it is in etheir of my cars
