Honestly, once the RAN network is built out....we're talking an extra 5 mins of charge per stop to make up that 10-15% (per Rivian, 140 miles in 20 minutes) reduction in range with the 20s. No worries.

It will be 7-10 years for that system to be built out if ever

Really easy...borrow a friend's Prius and drive it carefully, trying to keep it in electric mode and work to achieve >50mpg...a training exercise. Then drive fully electric, trying to keep the kW usage to a minimum...extending range. Drive slowly around curves and corners, very easy on the tires. Accelerate slowly, except when you are trying to impress someone, but only occasionally.

Before you know it, you will be driving like an old man like me! Seriously, my BoltEV is pretty quick also with a low center of gravity, and it is almost as fast as a Tesla. Driven in Sport mode, it will spin the tires. But if I drove like that, I would do exactly as you say, eat up the tires. I know what my BoltEV can do, and I use that to my advantage when I need it, but most of the time, I don't, and I have 51k miles on it currently...granted they are pretty close to needing replacement, but I am waiting on a replacement battery before it burns...ha ha, hope that is joking!

I almost always get above 60mpg and often get around 70mg around town. The key, as it will be for extending range in an EV, is to avoid hitting the accelerator hard (except when you must) and maximizing regenerative braking, often allowing you to avoid coming to a stop which ends up helping with that acceleration loss. I'll sometimes even wait for that slight downhill I see up ahead to pick up a few mph to save on acceleration. Do people hate driving behind me? Some of the time, sure.

No one has to drive the Rivian like that all the time, but it is good to know that your behavior can buy you some range if you need it, though less so on freeways.

I would‘t count on Regen to save you anything.

I would‘t count on Regen to save you anything.

Why?
In a Prius, with a small battery, you can see how much the regen charges the battery, allowing you to go further on battery power, saving fuel. Why would it work differently in anything else? Why put regen in if it doesn't do anything. A lot depends on driving conditions, but I can get significant regen coming off a freeway or even approaching a stoplight in town from 45mph. This regen battery power can provide my acceleration from that stop, assuming I'm not getting on a freeway again and having to get up to speed quickly.

The 316 mile range is achieved by using regen. Were regen disabled during the dynamometer testing the resulting range would be appreciably less than 316. And so if you turn off regen when driving or if you use it in a suboptimal way (meaning if you ever engage the friction brakes) you will lose the benefit. In precise terms regen won't gain you anything but it does save you a lot of what would otherwise be lost.

I fully agree it will take time, but 7 - 10 years?

The Electrify America brand was unveiled in January 2017, along with its first phase of station buildout. Its first station opened in May 2018, in Chicopee, Massachusetts.

EA’s plan is to have about 800 charging stations and about 3,500 individual chargers in the U.S. by the end of 2021. As of July 2021, Electrify America has installed 635 charging stations in the United States.

RAN's goal? 3,500+ DC fast chargers at 600+ sites through 2023... The first DC station that I can find, looks to be close to opening in Inyokern with 10 chargers.

RAN's plan is technically possible, though variables for land acquisition, leases, permits, supply chain etc... will all play part in the actual timeline.

When I took delivery my Model S in October 2016, EV charging options were very limited for both Super Chargers, and CCS. Today there are SO MANY more quality charging options for all EV's, which is progress, and will only keep on getting better for all EV brands! Let's see if we can duplicate or exceed charger growth of the past 3 years, and get it done by 2023!

Please dont us the word Prius in a real car discussion.

In the image I posted here from the configurator it states Separately that the "off road upgrade" AND the "wheels" "can affect range".
So does this mean that the off-road option will affect the MPGe plus the 20"AT wheels as well?
If you do not get the off-road option will that help MPGe be a bit better even with the 20" AT?
What do you all think.
Thanks Revo

Good luck with that.

did you happen to notice that Tesla is miles … sorry light years ahead of everybody else in the charging world. And, they just completed a factory dedicated only to building a ton more of the chargers.

EA is way behind and the problems with maintenance is well known.

Sure, but if they engaged in "normal" driving, it is possible to drive with greater focus on efficiency. Thus it is likely that someone could see modest improvement on that number if they make the attempt. I regularly achieve above the EPA mileage estimate in our Prius while my wife generally gets a little below it. Both of us drive in "normal" conditions, but I try to maximize mileage and score.
Regeneration isn't so much about if it is on or not but how you use it (or don't). It is also why you'll generally see less variation in freeway mileage - less braking means less chance to optimize regen or fail to do so by engaging the friction brakes.
I'm not convinced that EPA testing results from optimal driving. Maybe I'm wrong in this case.

Yes, off-road pack adds weight and probably hurts efficiency a bit due to the less aerodynamic tow hooks up front. We knew it was going to hurt MPGe as soon as they told us it was optional instead of included. Only the naive really thought it was because "our customers told us they didn't want it".

The real question is how much of a reduction will there be? I think it's clear that it's at least 15 miles, which would have dropped them below the magical 300 number.

I'm guessing with 20's and the off-road package you're looking at ~250 mile maximum range (15% reduction for the wheels, plus some additional for the off-road pack)

The Prius is a real car. While the glory days of the Prius are likely behind it, given the rise of fully electric vehicles, the Prius was an important gateway towards reduced emissions and increased fuel efficiency. Not only that, the Prius is a technological marvel simply because of how well it does its simple task at its price point. The Prius is at once simple and yet functions better than its rivals, none of which ever found much success in the Prius-dominated market.

I feel dumb that I did not think of the weight side of it.
Thanks for making me smarter lol ??
