The future is here! https://www.adventure-journal.com/2...390135429&mc_cid=1a7c00a002&mc_eid=b32c2c8274


0-60 in 2.8 seconds, pivot like a tractor, 3' water crossing depth, 400 mile range charge in one hour.. heck the thing will even drive itself when you're tired. You want one.

I like the Rivian pickup better but the 70-100K price is a little steep. Atlis has a 40,000 something pricing target on their pick-up. More realistic for the average American.

I happy to see what looks like an honest race to put an electric truck to market before Tesla.

Ok as long as we're showing all, may as well confess I've been watching the Bollinger also... https://www.bollingermotors.com/

Could be the fan favorite, and actually looks like they're designing it for some off-highway capability. 0-60 is like 6.5 seconds though, so that's a lethargic Porsche compared to the Lambo-like Rivian. :bolt:

will be so cool in a couple years to see these things on the road..

Despite Bollinger definitely building what looks to be an actual wheeler it has not grown on me yet. The specs are pretty impressive. 6.5 to 60 is rather slow for an EV but compared to my 80 Series it’s like a top fuel dragster.

A 400 mile range is fine by itself, that's actually 100 miles more than I do on a tank in my Taco. However 5 minutes at a gas station returns me another 300 miles so it's the recharging that seems to me to be the crux. But then again there's a Telsa Supercharger at the Blanding visitor's center, so that is being addressed. Still waiting an hour isn't as nice as splash-and-dash.

But any idea how the range reduces using these things off highway? What is the equivalent of carrying jerry cans? A generator I suppose. But that's gonna take a day sitting in one place. I think hybrids have to be the solution for 4x4.

Not to mention the effect of a full load on range. You pack that thing up like we do to our rigs and your range will drop much more than my mileage.

I like the pickup truck version of the Rivian. I am not sure why, but this vehicle is so odd that it actually comes full circle to looking good. It also comes with a frunk. Oh, and a sort of trunk. It also sounds like they are setting the truck up with pretty good armor from the factory due to the battery being below the vehicle.

Does anyone else cringe at driving through 3 feet of water with a ~200kw battery pack submerged below the vehicle? That just sounds like the plot point in Final Destination to me.

My understanding with most electric vehicles is the biggest drain on range is seeking to do primarily fast highway speeds. They are capable of doing the higher speeds, but it drains the battery more quickly per mile due to drag and not being able to utilize regenerative braking very often.

I definitely wouldn't test the water forging capabilities. The worst that can happen with a gas vehicle is hydrolock the motor. With the electric you can fry all the occupants and any wildlife within 30 feet.

In my moto experience, I get better mileage when it's technical terrain compared to highway. And if I one could actually charge back up with a day in the sun, then just design your trip around that? If you gotta be back at work on Monday then maybe don't run out to the Dollhouse... but shoot if you had a few days then what a cool trip.

Portable solar isn't going to cut it. Consider if you use 180 kW-hr to go 400 miles then a 200 watt solar panel will take 900 hours of ideal sunlight to collect the energy. Current state of the art PV panels produce about 18 watts per square foot. Over a whole day a panel probably makes about half its rated output and at night its zero. So it'll probably be quite a lot of time using a little solar panel.

So drag along a 2 kW generator, which will still take 90 hours to return 180 kW.

Those Telsa Supercharger stations can deliver 72 kW, which costs about $0.22 per kW-hr. So a 400 mile trip that used 180 kW-hr costs $39.60 (that's probably equal to doing it in a car). To get a handle on that, if you have a single phase 240 V, 200 amp service to your home it can in total summing all the circuits deliver 48 kW. It would take you and your neighbor's full service running 100% for an hour to charge after a 400 mile trip. It would take I think two 50 A / 240 V circuits overnight to charge the 180 kW-hr battery.

For comparison a gallon of gasoline delivers about 33.5 kW-hr equivalent, which means a Telsa station works out to about $7.37 per gallon equivalent and a 5 gallon jerry can carries 167.5 kW-hr.

You see the clear increase in efficiency of the EV itself since there's so much lost to heat in internal combustion. That inefficiency, BTW, is just shifted to the power plants though...

Which also means you'll need to bring along something like 20 gallons to run the 2 kW generator you'd use to get back from the Dollhouse by next week due to the inefficiency of its gas engine.

Like I say, just generating the power directly using a hybrid engine and collecting regenerated braking power, solar, etc. to increase overall vehicle efficiency makes sense. A pure EV only is practical if you're never far from a grid-tied charging station.

I had an electric smart car I leased for $100/mo as a commuter for a few years. Did great to drive me 50 miles/day. Cost me about $40 in electricity per mo, so for $140/mo I was paying less than my fj62 fuel bill would have been for that same commute while keeping it off the road.

Best thing about that car was that it was instantly warm in the morning, no waiting for the engine to heat up, and in Cleveland that was amazing.

I don't really buy the argument about transferring the inefficiencies of the internal combustion engine to the power plant when comparing gas/electric. Obviously most of the power you are putting into your car came from a power plant using coal, but even those less efficient power plants are much more thermal efficient than an internal combustion engine. Something like 20% efficient for an IC engine, and 35ish% for a coal plant. It takes energy to refine oil as well.

Either way, having to go on long road trips would suck waiting to fill up for an hour. Unless maybe you are sleeping the entire time via autopilot and autofueling at some point.

For a local commuter car combined with solar panels and a smart battery pack like the Tesla Powerwall, you would have a hard time beating it. You have some capex up front of course, but your ongoing "fuel" and electricity bills would be zero. Add in some tax incentives and feel good for doing your "part" as it relates to climate change, and that's a heck of a setup. The only real challenge I can think of would be long road trips, but you can keep an ICE truck around for that. Like it or not, this is the way the world is going.

There was a company for a while, maybe chevy, that would give you so many car rental days per year for road trips if you bought their electric car.

That would be some really serious amperage that this system could deliver VERY quickly. Especially to get a 5000-6000lb vehicle to 60 MPH in 3 seconds.

Sorry Rivian, but Toyota already beat you to the punch with "This is not a car"

what a minute, my 40 doesn't have a chain on the gas cap or the oil cap. And I can shift into 4WD without stopping? I've never done that.. maybe we got robbed in '82 by this loss of features.

don't get the "you can't lock yourself out" comment either. Is that because I can get my kid to reach in through the vent & pop the door?

You know, now that I think about it I haven't ever locked myself out of a Toyota truck. So that selling point is true.
