How does the cap affect range? Is the aero benefit greater than the weight penalty?

We've had the cap on for about 2/3 of the driving so far, but I don't think there's been any impact on range from the cap. I doubt there's much overall aero benefit to the cap, but I've also realized that weight is not a big factor for range for us, as long as it's inside the footprint of the bed/cap. Something sticking up high above the cab would have a much bigger impact than more weight down in the bed. We don't need to do any towing, and I probably wouldn't have gone electric if we did.

Overall, speed, temp, and big elevation gains are the biggest range hits. The worst range for us is usually driving 75mph on I90 up to Snoqualmie through gusty winds, but that's also our shortest trip for skiing and well within reach. 60mph on 2-lane roads is notably better. We averaged 2.4 mi/kwh over 5,000 miles, which is about 310 miles for range. We'll see how a full winter of driving it changes the numbers, but seeing more like 260 mile range for snow/cold driving so far. In some ways, WA is pretty ideal for this, because a lot of our ski driving is moderate temps/terrain until the last bit of the drive.

WMD - good to hear! We had a few ski days in 0 degree temps, but never got to really test fully range below zero. I definitely agree on how comfortable it was to drive in those temps!

I had a mech eng (hvac) leading a continuing education session on the coming wave of electrification in homes, and his current recommendation for battery system value was getting a Lightning instead of a Tesla Power Wall

that was pretty interesting statement, and a little surprising

It makes sense - the truck has a 131kwh battery. For a true household backup, I'd need to drop some $$$ on the full integration system/inverter/transfer switch, which I think is probably in the $8-12k range depending on needs and configuration? It might be something we do down the road when they get the bugs worked out, since I'd really like to be able to cover furnace, cooktop, and water - thinking more about long-term risks like earthquake or other disaster.

For the just cost of a couple extension cords, I can cover the things we need in short-term storm or system outages, which is hard to argue with for right now. I have heard of others taking sort of a middle route and installing a Generac transfer switch with a few key household loads and just plugging that into the bed of the truck when needed. That would cover hardwired household needs without the full expense.

Power was out for about 7 hours, and I ran had the truck running in the garage providing power for about 5 hours - silently, no exhaust, no carbon monoxide. It used 2% over 5 hours, so barely a dent in the battery capacity to weather a power outage.

Awesome Truck - Very cool to use the backup.

Amp draw for consumer electronics is essentially nothing. So not surprising you used a minimal amount. Your slope side hot cocoa operation could easily burn more juice than 7 hours of laptop and monitors…

Cool discussions.

Anything with a heating element will have bigger draw.

The Tesla wall vs lightning for home backup, yer trucks gotta stay at home during the outage, right?

No, you just leave the battery behind and go do whatever you were planning to.

Lithium prices have been dropping which is awesome for electrification.

I think some kind of Hybrid system.

10-20 kWh battery backup at home

and a mobile charging unit (truck/car) that is 60+ kWh to grab power somewhere else in the event you need it that also just so happens to function as a car.

Also a robust solar system (5-10 kw)

I'm planning on building a DIY electric pontoon boat this spring. Fiddling with all the batteries etc makes me want to buy some kind of diy 100 kWh lifepo battery system + solar and pull the plug on the grid.

My car will only do 1.5 kw @ 120V power V2L (vehicle to load) though which kind of sucks, the euro variant does ~3kw @ 240v. I have a somewhat new HVAC system so it makes no sense to rip it all out and go heat pump though which kind of stinks.

Lol.

Pretty sure I’d just take our other car. Or if unavoidable, just unplug, go where I need to, and then plug back in. 🤷♂️

Just saw some sort of hydrogen industry press release that BMW is apparently shifting from e cars to H cars. Difficult to understand full effect of that type of shift over time.

I am onboard the moment Rivian begins taking deposits on the R3X. Let's hope those wheels end up on the production model.


3 motors, AWD, 0-60 in <3 seconds. Looks like a cross between a GTI and Lancia Delta. I love it.

“We need to understand the consequences of these rate increases on climate change,” he said. A Pew Research Center survey found 70% of people interested in buying electric cars said saving money on gas was a major factor in their thinking.

The rise in PG&E rates affects a significant portion of the country’s electric vehicle drivers: The utility says that about 1 in 7 EVs across the country plugs into the utility’s California grid.

Rivan 3X looks awesome. Honda Prologue seems to be a similar ride at a similar price and worth keeping an eye on too.

Ill take pump jacks any day over fields of brine ponds...

The only people winning this electric (thats not at all environmentally friendly) transition are the lobbyist idiots.

It's a good article, but it doesn't address the burning of the fossil fuels, only the emissions from mining fossil fuels, which the article admits is more than produced in the mining of Lithium and Cobalt. So not only does the mining of fossil fuels produce more emissions than the mining of Co and Li, there's the problem of millions of smokestacks driving around vs. far less smokestacks at energy producing sites that can be more closely monitored.

Though emissions deriving from mining these two elements are lower than those deriving from fossil fuels production, the extraction methods for lithium and cobalt can be very energy intensive

Anyway, not sure why you hate electric cars. They make perfect sense for 90% of the folks who drive.
I mean I loooove going to a gas station.

Doesn’t seem like the Prologue will be in the same class as the R3, quite a bit bigger:

https://www.roadandtrack.com/news/a6...ghties-design/

Prologue is 192” long. Sounds like the R3 will only be ~178”. R3X will be a rally hatchback, not an SUV.

R3X sound sounds like it has the potential to be great.

Yeah. Electric rates here are 40-50 cents/kWh depending on when you use it and how much you use. California electric rates are not making it easy to be green.

I've poked around but still don't understand why they are so high. Last time I paid that much, I was on a remote diesel powered grid.

The R3X is the great car nobody buys.

This. Millions and millions of people in the US live in non-attainment zones for PM2.5 and ozone and zero-emission vehicles are the only thing that will ever fix that problem. That means BEVs or some kind of hydrogen tech, and BEV tech is currently way out front.

[J. Barron DeJong]

Good chance of that, but probably comes down to the price premium.

I’m guessing it will have less downsides than most other ‘performance variant’ cars, given the suspension is actually raised instead of lowered vs. the standard model. May bode well for daily driveability.
