Longest Coast
 

Just curious, what are some of your guys longest coasts?

I realized this the other day when my part of trip that goes into Cumberland I'm in neutral for 6 or 7 miles (I'll get an exact reading)

The terrain rises and falls, but overall it is a huge (11% grade) drop from the Eastern Continental Divide down into Cumberland itself. Half the time I put the car in gear just to keep control of the speed.

I would say 1 mile. Then again, it's pretty flat where I live.

How much fuel do you burn going back up?

There's a mountain next to Mono Lake in California on highway 395 that it seems like you're coasting forever. I google mapped it and it looks like about 11-12 miles of coasting, might be 5-6, hard to tell on a 2-D picture. Made that trip I think 2 times, love watching my instant mpg go up to 120 :D

Only about 2 miles for me.

Obviously a lot more, and it's why my trips east always use less fuel than my trips west. It's also why I only started logging round trips instead of E/W.

But going up the mountain, I get about 17~20 mpg. Which works out to 35~40 mpg round trip. "Pulse and glide" :turtle::D

Truckee, CA to Verdi, NV is 30+ miles with no more than ~3 pulses needed when there's traffic.

I don't know for sure how long the coast is but it's loooong:thumbup:. I live in the Rocky Mountains and the longest coast is when going over Highwood pass, the top of the pass is over 7000ft I would estimate the longest EOC is 5 - 10 miles. The most frequent long coast I encounter is about 3 miles long, and is quit steep, if I start at the top at 30 mph I can EOC to over 80 mph :pbefore I have to brake for the 30mph zone at the bottom of the hill! Talk about a soap box derby!:eek:

I had really looong glides in the Coupe when I had that nice 40 mph perfect tailwind and got 69 mpg. Sadly I don't remember how long the p's and g's were.

Here's one from the loneliest road in America, US Hwy 50, in central Nevada.

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. :D 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.

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.

I was just wondering what the northbound distance on the grapevine is. It's been a while since I drove it, but I remember coasting for ages and being passed like I'm standing still by triple trailer semi trucks.

Longest coast is probably coming off Mt. Rainier or Mt. Hood. Might be as long as 10mi or possibly more. I've always loved mountains because it is a forced pulse and glide. Pulse up the mountain, glide back down. I've had 34mpg tanks in my Subaru thanks to mountain driving.

My 7 mile 1-way commute includes about a 1mi coast home with some smaller ones thrown in.

There is a good stretch of down hill from Mt. Baldy, Ca. I start coasting from the school all the way down to Padua Rd. its 6.7 miles. There is one spot where you go up a small hill after a steep one going 65 and I barely make it over the hump at around 10 mph...lol

11 mpg up the mountain and a bigillion going down in neutral at 50-65 :)

Anyone do a pinewood on US 157 Nevada. From Mt Charleston, straight 17 miles.

The longest I have ever coasted without starting the motor was from Rock City to the base of Lookout Mt....I regularly cost 10-15% of all my nearly flat drives in central and northern IN.

I'll have to measure (I'm sure its not very far) but there's a parking garage downtown that I always have fun coasting down. Its always packed so I have to park near the top. If only I had an elevator to the top.

No EOC coasting in my rigs, but this one is quite nice.
Google Maps
From the sharp bend at the middle-right to the junction of 123 and 12, it is about 9 miles. it drops from the summit at 4500 feet to about 1500 feet at the junction, nice 45~50 MPH curves.

Here's another one: Westbound CA 58 from Tehachapi toward Bakersfield: 110 mpg for 28.5 miles - pretty much the equal of the Grapevine.

Nice. I just recently learned about that route out of LA. I still haven't had the chance to drive it, though.

It's my route to Vegas. Any route away from the LA traffic is good!
