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!
