Replying to: moocow1 (May 25, 2008 11:57 pm) I have to disagree with that as a general statement. My 2004 Elantra AT is quite aerodynamic for a compact car. There is a significant difference in mpg at 55 vs. 70. At 55, the engine is loafing at around 2000 RPMs, and can easily get near 40 mpg on level ground at that speed. At 70, the RPMs are around 2700 (I forget exactly how fast) and mpg drops to around 35 mpg on level ground. I have found similar behavior on every other car I've owned over 30+ years. There is discussion in the press about resurrecting the 55 mph national speed limit, to save gas. Already some states are dropping their speed limits. On a long trip, I can see the benefit of going 70 vs. 65. On around-town driving, I think the gas savings in slowing down far outweigh the little bit of time saved. I did a test once. I drove a route I frequently travel across town, mostly on an urban freeway but with some city streets and stoplights too, about 7 miles total. On the way to my destination, I drove the speed limit (55-65 range) on the freeway and tried to use as light a foot as possible on the gas, considering conditions. On the way home, I drove much more aggressively, went 5+ over the speed limits, didn't pay any attention to how hard I was pressing on the pedal, and sped away from stoplights. I got about 24 mpg. I also saved a whopping 1 minute on my trip. |

Replying to: backy (May 26, 2008 12:20 pm)  2K when maintaining speed). I think your example of an aggressive driving test is more an example of accelerating, braking, accelerating, etc, rather than driving at a relatively steady speed. Back to my great old 1800E, on a highway trip of 350 miles (notwithstanding wind resistance) it just seems that 5 hours at 70 mph vs 7 hours at 50 mph would result in better mpg at the higher speed in the higher gear. |

Replying to: 2002slt (May 26, 2008 7:07 am) Well I don't live in IL, I live in TX and the speed limit here is 60 mph. Driving 5 mph under that limit is hardly impeding traffic. It's called a "speed limit" for a reason, meaning it's the fastest you're legally allowed to drive. It doesn't mean you have to drive that fast. I wouldn't care if the speed limit was 65 mph, I would still drive 55 mph. As far as I'm concerned as long as I'm in the far right lane, if you don't like how fast I'm driving then go around me. I'm not going to speed up and waste my money to accommodate some impatient motorist behind me in a big rush to go nowhere. Hey, if people want to go flying around at 80 mph wasting gas that's their prerogative. However for every mile per hour faster than 55 mph, fuel economy drops by about 1 percent, and the drop-off increases at a greater rate after 65 mph. So with gas prices dangerously close to $4.00 a gallon I will take every bit of gas savings I can get. And if it means driving 55 mph instead of 80 mph and taking a little longer to get to my destination, then so be it. Unless you work in a job that requires you to drive, then time does not equal money. My priority now is to save money on gas, and I will do everything I can to make that happen.

Replying to: craigbrooks (May 26, 2008 4:16 pm) But speaking of that 2009 Sonata... that would be a nice car to take on a cross-country cruise, huh?
