The question that many will have to ponder is: "do I get a barebones Tesla for $35K or a fully equipped LEAF for the same price?"
If it is for Local Driving only, then get the Leaf. If you wish to use it for long cross-country vacation driving then get the Tesla. Even the 200+ mile Leaf can not be practical for trips greater than 300 miles. jmho
Just curious. Why wouldn't a 200 mile leaf be practical for trips of 300 or greater miles?
IMO, 250 is the minimum number of miles for long distance travel. 280 is a good realistic number. And unless Nissan does something about providing more cooling, based on my experience fast charging my 30kWh LEAF just twice in a row at 40kW charging (battery temp related), I'm not even sure about those numbers when it comes to the LEAF.
Here is my reasoning: First I will define "long distance". I'll define local travel as 120 miles or less (that may sound like a lot, but 60 miles each way, or a 40 mile triangle is kind of what I'm thinking). Regional travel is up to about 350 miles (away from home). This is actually a pretty good distance. From my home in Raleigh, this gets my to Baltimore to the north, Savannah, GA to the south, and Knoxville, TN to the west. This kind of travel might even meet most people's travel needs considering they might fly for distances longer than this. But with the cost, delays, and hassles of air travel, my personal threshold for flying vs driving is 8 hours of driving (480 miles) when it's a direct flight (pretty rare) and 16 hours (960 miles) otherwise. Particularly when traveling with more than 2 people. In particular, we have a particular trip to take once a year that is about 800 miles each way.
So I originally went through a long derivation of how much charging "overhead" (in time) you would experience assuming various charging rates. I'll spare you the details (although let me know if you want them), but it basically works out to about 30% overhead if you assume 50kW charging. And before you come back and say that there are 150kW standards being proposed, let me respond by saying that the 50kW network (at least where I am) barely exists (and in some directions doesn't), much less some hypothetical 100-150kW network which will do me no good if I need to take a trip next year. But for the sake of argument, even assuming 100kW charging, you can cut down the overhead to 18%.
Now the benchmark I am trying to hit is the overhead we currently have while taking our annual long trip in a gas vehicle. We currently do this with between 15-17% overhead. So okay, the 100kW charging at least gets close. So assumption #1 (for me anyway) is that a long distance EV will have to support at least 100kW charging to be competitive.
But will a 200 mile EV do the trick, or do you need more?
Well let me first say that I don't necessarily envision driving your EV until it reaches 2% SOC and then sitting at the charging station until it hits exactly 80% and then going. Rather I see stops timed more or less with potty and meal stops. And since my bladder range might not even be quite up to the range of the higher capacity packs, this probably means I won't have to fill all the way up to 80% to make it to the next stop. This is good because it minimizes the effect that tapering off will have, and means I don't have to sit for as long twiddling my thumbs waiting to hit that 80% (in the case of a high range car needing a full 80% at a lower speed charger, you might be at the stop for almost an hour 20 minutes, which is even long for a meal).
Now here's the problem with the 200 mile range car. Whether your bladder needs to or not, you will need to stop AT LEAST every two hours and charge for 30 minutes. AND, you better hope the charging stations are spaced at these perfect intervals. Otherwise you're may have to stop at even shorter intervals to make sure. And as I said, the CHAdeMO/CCS "networks" barely exist as it is. With 250-280 (or more) range vehicles, your window expands to something a bit more comfortable. If you have to stop in 2 hours, fine...but then you don't have to fill all the way up. If you can make it 3 hours, but you know you will be stopping for lunch in another 2, then go ahead and cut the charge short.
Now here's where we get back on topic to Tesla. So Tesla has chargers that do support 100kW+ charging today. There is an actual network of them. They are spaced out at intentionally even intervals. They are sited near amenities. Even then, from my area, going in the direction I take annually, it is 278 miles to the first Supercharger (the road I take, US-29 through VA, is not an interstate (although portions are limited access with speed limits of 65-70) so likely not a target for future SCs). There is one planned for Charlottesville, VA at 200 miles away, but this takes me over 20 minutes out of my way. The closest CHAdeMO charger on this route is 230 miles away, and it is a SINGLE charger. So the going in that direction is tight, for sure, for either car. But the long range Model 3 could, in theory, make it. The hypothetical 200 mile LEAF could not. Taking an alternate route north towards I-95 (which I like to avoid), the first Supercharger is only 80 miles away and this gets me to interstates which will serve well. The closest CHAdeMO in that direction, however, is again a SINGLE charger at a hotel 135 miles away. Okay, at least doable. Heading south to Savannah, Supercharger is 108 miles away. For CHAdeMO I would have to go out of my way to get to a Nissan dealer in Fayetteville (about 90 miles), but then where? There is not a single other fast charger until Savannah (261 miles). So SOL taking a 200 mile LEAF in that direction. Going west there are actually several options, but the pinch point is probably a single charger at a Nissan dealer about 160 miles away. You would have to stop there to get a charge to make it the next leg. But to make it there comfortably you would probably also have to stop at another Nissan dealer as well. Again with Tesla, this is all well spaced-out. You could actually make it to the Asheville Supercharger (242 miles), but there will be 2 other opportunities before that as well.
