Softness or hardness of the rubber compound can affect mileage. 4. Speed rating - the higher speed tires are generally performance tires with softer rubber compounds. Passenger car tires are in some way or another some compromise - handling and performance for ride and comfort, decreased rolling resistance for aggressive tread and rain water dispersion. Unfortunately, unlike F1 or other race cars - we have to do with one kind of tire for all conditions - race cars can and do change from soft aggressive rain tires to dry weather smooth surface tires for high performance. If you live in AZ, I suspect you seldom need rain tires, so you can go for a hard rubber compound with low rolling resistance and a less agrressive tread pattern. Seattle? Softer rubber, aggressive water dispersing tread pattern and higher rolling resistance. The exact same car's mileage will vary with locale and types of tires. Most GOOD tire merchants will have comparison charts for you that have them rated for rolling resistance, noise, revolutions/mile, etc. Changing tires can have an enormous impact on MPG - sometimes for the better, sometimes not. |

just did a round trip from Philly to NY (about 240 miles). Mostly highway, a little local in the middle. For a change, no traffic delays. Lots of troopers, so I mostly ran 65-70. Got a tick under 36 (35.9). Just me, no luggage to speak of, no AC and windows and roof closed. IMO, about the best I am ever likely to do, and pretty darned good for a car this size and comfortable. 2005 EX-L 4 cyl 5 speed stick (just hitting 24K on it).

A manual transmission Accord can run low 7s to 60 MPH. That's faster than the pocket rockets of a few years ago! I have the auto, so not quite as quick and involving, but it gets better highway mileage (taller gearing) and is great in point and shoot traffic. I love it! TheGrad 2006 Accord EX I4 5AT

Replying to: ljgbjg (Apr 09, 2008 5:23 am) No projections are needed in the wind tunnel, though, as the Accord has already bettered its performance due to a drop in the coefficient of drag from 0.34 to 0.31. I'd like to know how they accomplished that as the frontal area does appear to be more substantial than the gen 7's.

Replying to: malmouza (Apr 09, 2008 6:10 am) Or just get a car from a manufacturer that does not mind is engines "loafing" along. Check out some V8's from GM - at highway speeds they cruise at 2000 RPM at 80MPH because of the overdrive. Result? 28-29 MPH from a V8 - and no VCM! |
