Longest Coast

[ecomodded]

12 km or more if I catch a light, Down a pass and into my City, half way to my house.

Flat terrain, not pressed by traffic: A half-mile to 0.7 mile.

I have a 7 mile coast (not all down hill), if I hit the light at the end right add another mile. In addition to that, I have several coasts on my way to work over a mile. With the f250 I can coast up some impressive hills (7250+ pounds of momentum).

Hello -

12 KM or 7 miles is *wonderful*.

I rarely do this, but there is a part of the Glendale freeway (also called the 2 freeway) going South between the 134 and the I-5. That has maybe a 4-5 mile downhill stretch that you can coast.

Otherwise, I may have a 1 mile stretch here or there and always depending on the traffic, but no glory roads.

I think my longest is the first 3.1 miles of my commute to work. Usually I get out of this for .01 gallon of gas just to get out of the trailer park. The rest is all downhill. I do have a couple 2plus milers on the rest of the round trip. My "calibrated hill" may be longer, but I'm usually paying more attention to my surroundings and speed than distance. Guess I'll have to check to be sure.

I've found a few different places that offer some pretty good coasting. One road (on my route home from work) offers about 2 miles where I don't have to touch the gas at all.

Also, I have a few other routes that offer some decent coasting or high mpg cruising, but most of that has to do with traffic. I've found that inconsiderate, inattentive, or just plain ignorant drivers tend to inhibit my ability to coast more so than any other factor. I digress, but just today, a CalTrans worker stopped his company vehicle perpendicular to traffic, shutting down two lanes. It was completely unclear what he was doing, so I merged into the left turn lane (an alternate route for going home). As I started to drive with the green left turn arrow, he smashed his gas, nearly t-boning me, made a 3-point turn into the left turn lane, and came to a stop as the left turn light changed to yellow. I guess rules of the road don't apply when tax payers are paying for your time and your gas.

On my daily commute I have a 1-mile coast, 10 second pulse and then another 1 mile coast. Sadly, it's not so much fun going home.

My best ever was 16 miles on I-80 dropping down into Salt Lake City. Start at 7000 feet and drop down to 4200 in the city. Momentum took me halfway into the city (still on interstate) before having to add power. Winding down through the canyon at 80+ with perfect wide sweeping curves was awesome in all senses of the word.

"Loneliest road in America"? Not even close. Next time you're out that way, if you want to get out of the traffic, try Nevada SR 722, which runs a bit south of that.

Longest actual coast would have to be California 88, from Carson Pass at 8650 ft east to Woodfords, maybe 15 miles. With a little bump over the hill out of there, it'd get to maybe 20 miles, ending somewhere on the flat stretch into Gardnerville. (I probably could do this in one coast, if I didn't have to brake to stay reasonably close to the speed limit.)

The other way, going west, has a couple of climbs, but I can get nearly into Stockton (about 65-70 miles) with the trip mpg display still pegged at 150 mpg.

Here's another candidate: the southbound Grapevine (I-5) from Tejon Summit to Valencia, CA. Any time you can average >100 mpg for >30 miles, you're talking about a long downhill coast.

[Ladogaboy]

Hah, yeah! Last time I made that trip, I averaged 38 mpg (good for me) including the last 10 miles of flat freeway and about 6 miles of city streets.

Also, the first long coast route I posted here... I JUST missed a one in a hundred chance to extend the coast for at least another one to two miles. Basically, at the end, I have to neutral coast down one hill, all the way up to the top, hope that the light is green (rare), and still have enough momentum to carry me through the corner and back down another grade. Sooo close... I'm talking about just a couple of feet.
