Great video, introducing LVNP in 4 minutes...

Of course, much better to see it for yourself, and no better way, IMO than in a LEAF.

You not only can enjoy the Park, but after experiencing 80% to 90% recovery of ascent energy over the (~8,000 ft net ascent) trip, you will never fear hills again.

The Peak road is only open late Summer through early Fall, but since quite a few LEAFs now seem to be making the ~I-5 trip through North California, I encourage you to get off the corridor.

I made three trips to the Peak trailhead last Summer (recharging at ~mile 47, the second red line on the profile) the last two times returning Via highway 36:

HWY 36 is actually easier to drive efficiently (that is-slowly) than HWY 44, as it has no 65 mph zones and more passing opportunities.

To do this trip Redding-to-Lassen Peak-to-Red Bluff with only one charge stop (near Shingletown, and near 4,000 ft. elevation) you will probably have to drive below prevailing speed on some of the higher-speed stretches of highway.

To give you an idea, I drove my route the first time in 5 H 47 m total drive time (as compared to the
Google 4 h 22 m (add another ~ 5 minutes to that for the ~0.7 m of my driveway off the map) estimate.

Not knowing some of the route, I drove much too slowly, and got the LBW less than a mile from home.

The second trip, cooler temperatures, on nearly new tires (both reducing efficiency) I made it in 5 H 32 m, arriving at my door well before the VLBW, as per plan.

112+ miles on a single charge is much easier, when you recharge above your destination, and have ~2,000 ft. worth of (potential) energy backing up your battery!

Redding to Redding, or Redding, to Red Bluff, are both shorter and require ~1,500 ft. less descent and ascent and than the trips I make, so you shouldn't have trouble driving either on a warm day.

And most days the road is open over the Peak, it is warm, 90 F to 110 F down in Redding and Red Bluff.

The Upstate California Plug-in Electric Vehicle Readiness Plan shows a DC in Shingletown on their map:

viewtopic.php?f=51&t=3319&start=20

Which of course would save hours of LEAF recharge time on any Lassen trip .

But I wouldn't wait for it...

Highway 89 is closed at the North and south Park entrances until next Summer, assuming we get at least normal snowpack this Winter.

http://www.nps.gov/lavo/planyourvisit/c ... UMP_218946

I've seen the preliminary draft for the Charge station grant application I mentioned last Summer, and it requests funding to put dual L2s at both North and South Park entrances.

Cross your fingers...

Due to drought, the road was plowed early this year, and I made three trips over the Peak road, on 6/12, 6/30 and 8/19, all variations on the Hwy 44/89/36 loop I posted above, all from 160 to 161 miles, total ascent and descent between 13,400 and 13,600 ft.

I got home after each trip with kWh to spare, well before the VLBW with 33 or 34 gids indicated after each trip, having recharged to "100%" at ~47 miles and ~4,000 ft. on the way up, so I'd expect to be able to make this trip (on warm days, at low speed) for at least a few more years on my OE pack.

BTW, after an ascent/descent like this gives you some interesting dash displays.

Descending from the ~8,500 ft. Peak, my LEAF's dash display went from 1 to 6 Charge bars and from 4 miles on the GOM to 57 and 56, after ~37 and ~30 miles driven respectively. Anyone driven other roads where you can regen that much?

The Peak trail has been rebuilt and is consistently open (during the 3-4 months the highway is open) but on 8/19 the smoke was thick enough that I didn't want to put my lungs to the test.

This photo of the Peak from ~5 miles away was taken from the Echo lake trail.

Thanks for sharing. Hopefully by next summer, the drought will have moderated some and the air quality will be good enough to fully enjoy the Peak trail.

That's pretty impressive! Even with all of my mountain driving, I don't think I've ever gained more than four charge bars from regen. One limitation I face in the SoCal mountains is traffic - it's usually not possible to drive slowly enough to get maximum regen.

That's pretty impressive!...

Perhaps more impressive, is that any LEAF could begin a trip from the Lassen Peak summit parking lot and arrive at the I-5 corridor anywhere from Red Bluff to Redding, 65 to 75 miles away, with more energy in the pack than it started out with.

Start the trip at turtle if you like, for dramatic effect!

From ~mile 120 on my trip profile above you could ~follow Battle Creek east, avoiding the major ascents I need to make to get home.

With ~12 kwh of potential energy (depending on vehicle load) from the Peak lot to the Valley floor, and ~90% rate of recovery (blend of regen and direct) you'd need to drive at a ~6.5 m/kWh average speed (level) to make 70 miles with no net energy use.

For comparison, on all three ~161 mile loop trips this year, my LEAF reported 7.0 or 7.1 odometer miles/nominal kWh (what is shown in the nav screen m/kWh display).

No, My LEAF did not really get 7.0 or 7.1 m/kWh on each of these trips, or even the 6.7 or 6.8 shown on the dash M/kWh display, caused by it's 2.5% underreport error from odometer miles.

But I estimate that my LEAF did get a very respectable ~6.3 to 6.4 actual m/kWh, once correcting for both the underreport in my odometer, ~0.5%, and the underreport in my LEAF's kWh use, ~10.5%.

A ~6.5 m/kWh actual pace should be pretty easy to achieve on several slower average speed routes from the Peak lot to I-5, on a warm day.

The more weight you have in your LEAF, the easier this trip would be, of course.

A new hypermiling technique - load up the EV with rocks upon reaching the highest point of the drive! ;)

Re: Lassen Peak trip

Some more info for anyone wanting to plan a drive up to Lassen next year.

I estimate my LEAF used ~22.7 actual kWh to reach the ~8,500 ft. Lassen Peak lot, and ~25.2 actual kWh to make the entire ~161 mile ~13,600 ft. total ascent/descent trip, when I last dove this route on 8/19/15.

Which is why I would have needed to recharge en-route back in 2011, when My LEAF had ~21 actual kWh available, and need to even more so now, (~4.5 years and ~41,000 miles later) since my pack now only has ~18 kWh available to turtle.

I expect the 30 kWh pack probably has ~27 kWh available, so I'd probably be able to make ~the same trip at ~the same speeds on a single charge, in a 2016 SV or SL.

A loop trip from I-5 (there are two motels with L2s in Anderson) could only be ~127 miles:

https://www.google.com/maps/dir/40.4532 ... 06!1m0!3e0

If you were to drive very slowly on a warm day, you could probably do this trip on as little as ~21 kWh, but I wouldn't suggest trying it, even in a 24 kWh 2015, which is both more efficient and probably has slightly higher kWh than My LEAF had when it was new.

It should be quite easy to do this trip with kWh to spare, in a 30 kWh 2016, if you allow closer to 4 hours drive time, rather than the 3 hours 17 minutes show above by google.

BTW, I just noticed this Fully Charged episode showing the 30 kWh LEAF's excellent performance in Mountainous conditions:

I have found both or your mountain trip reports very helpful to our adventures. Your reports prompted me to report on our intercity trips, many of which I've posted here. All are up on my web site.

So, again, thanks for the reports.

And we hope to do Lassen some day.

You're welcome (belatedly) Paul.

Those considering planning a trip the 2016 season can get road updates at the site below.

Looks like the highway may be open all the way to the summit by ~the end of May.

2016 Road Clearing Operator's Log

April 25 - Thursday, we were able to clear to about 500 feet short of Jones Cut (about 3 miles from the Kohm Yah-mah-nee Visitor Center), today when we arrived it was snowing with very high winds and near zero visibility so I decided to call off the effort until tomorrow. If all goes well, I anticipate getting near to Bumpass Hell Parking Area (6 miles) by the end of next week...

New! The road through the park will open in its entirety June 12, 2016

https://www.nps.gov/lavo/planyourvisit/ ... update.htm

The Clean Cities grant proposal for four level 2 charging stations (two each at both North and south entrances) was approved.

Park officials are planning on a 2017 spring/summer installation.

Here's the view from Crags lake on 6/1/16. The trailhead is one of several near the proposed Northern L2 site.

Below is Mill Creek Falls, in a photo taken 8/24/14.

The trailhead starts at the South visitor center, where the other L2 site will be located.

Update on Lassen Peak.

Road open!

At last, Lassen park road set to reopen to through traffic

The road through Lassen Volcanic National Park finally will reopen to through traffic Thursday after nearly four months of snow-clearing work.

Thursday's road opener set a record for the latest opening date, park officials said.

"This year's opening of the highway will be the latest in park records dating back to 1931," Lassen Superintendent Jim Richardson said.

Since 1980, the latest opening was July 21, 1995, according to park logs.

The delay was caused for the most part by a snowy winter with the snowpack persisting into summer.

The final north-south section of the 30-mile Lassen Volcanic National Park Highway that needed to be plowed was between the Lassen Peak parking area and Summit Lake...

Snowfall in the park was about average for winter but it was more than the previous four years during the drought, Haner said earlier this month. A total of 28 feet of snow was reported over the winter at the summit of the park highway, which connects with Highway 89 at the park boundaries...

http://www.redding.com/story/news/local ... 514709001/

All the images on my previous posts have been photobucketed, sorry about that.

Here is a link to the route I often drive, ~161 miles and ~11,600 ft of total ascent and descent, recharging once on the climb:

https://www.google.com/maps/dir/27772+H ... 718518!3e0

Both times I drove this route last Summer (2016) I got the LBW just before the summit, and made it home after another ~81 miles, without reaching the VLBW.

As mentioned previously, it should be fairly easy to make the shorter trip from the I-5 corridor to the peak and back without having to recharge, if you have a "30 kWh" LEAF, choose a low-speed route, and drive conservatively.

Which you may want to (or need to) plan on, since the Park's plans to install L2 sites have reportedly been cancelled.

Here again is one ~127 mile route I suggested above:

https://www.google.com/maps/dir/40.4532 ... 06!1m0!3e0

PS:

I just noticed that the ~10 miles of unpaved Spring branch road above, the only segment which I've never driven myself, looks fairly rough in satellite view. I suggest you find current road conditions before planning that route.

Or instead try this ~133 mile route , which looks to be entirely paved, though in parts only one lane wide:
