Even if you do 100%, with just 1 year of used, my Tesla battery on 100% charge shows 320 miles, which is a far cry from 358 advertised. Plus the other estimates are correct. The range drops if it’s too cold, or if it is too hot, or if you use any of the features that the car advertises, or if you’re driving on a freeway, or if it is a stop and go traffic, or if you gain elevation, or basically if you use your car as…

EVs do much better in stop and go traffic. I wouldn’t be surprised if some even exceeds EPA range estimates in those cases.

USA traffic engineers love stop lights which force idling. Fortunately some European tech to stop/start the engine is arriving in USA. In isolated cases, some USA intersections are being converted to traffic circles. Installation of new stop lights should require a giant pollution fine paid by government.

Personally, my time in my car is some of the only pure "me" time I have, and I would hazard a guess that it is the same for many others. A car to me is a personal, climate controlled cocoon, where I can turn on whatever music I want, have a coffee or a snack, and escape for the 30 minutes or however long it takes to reach my destination...without the chance of being bothered by anyone else, much less any of the other…

I love driving as much as the next person but being on the roads at commuting time is hell on earth. Battling all of the other sleep deprived idiots to travel 3 miles in an hour. It's awful.

For occasional commutes, 115km one way is ok (not for me, but it's not unthinkable). But 115km each way (230km round trip) 5 days per week is a problem. We should not be doing this, at least not in individual cars. That electric car is still creating a lot of particulate pollution from the tires on the road, not to mention its contribution to general traffic. The focus should be on how to reduce the commute distance…

London has fantastic public transport.

If you preheat the battery I've noticed far better winter driving range. In fact, I only recently noticed because I always preheat the cabin which preheats the battery. Recently I didn't do that and was pretty surprised at how much energy it used while it warmed up.

If you typically plug in at home you should always be preheating the car before going out.

What portion of drivers use one pedal?

Are there EV drivers that do not? I don’t think I could ever go back to using 2 or 3 pedals.

I only use one pedal in stop and go or city driving. Otherwise it's harder to maintain smooth speeds and is less efficient than just coasting.

Author first assumes that only 60% of the available battery capacity is used (80% > 20%) and then arrives at the conclusion that the range is lower than expected. Well, no shit. I personally do charge my Ioniq BEV to 100%, and I often drive it to, say, 6%. In summer, I get a range of 220km, and in winter 160-180km, depending on temperature and number of cold starts (cold starts seem to trigger a battery warm-up). SOH…

I see colleagues that have to choose a new EV and use the EPA rating as an actual distance ("Oh I can drive to Paris in 1 go"). They don't know that you normally don't start from 100%, and you don't go down to 0%. Your 94% range usage is impressive, but not the norm for daily usage. Most people follow their vendor's recommendations for battery longevity.

Most people also don't drive 400km+ in "daily usage." When they do they charge to 100%. Just like in a gas car you don't fill the tank 100% every day. But you do before a long trip. Can you imagine the article "well acshually, your gas car daily range is much lower because you don't usually start with a full tank!"

Just did a 1000km (and back) drive this week, using a Kia Niro, which does about 400km on 64kWh. Was amazed I actually managed to drive this distance with 4 charges one way, and just 3 on the way back, reaching almost 400km actually on the first leg of the return trip (though this was downhill from the Alps). With longer roadtrips you want to go way below 20% remaining charge. With the quality of the charging-network…

That's not really amazing. That's a massive waste of time. I got 260km per charge in Enyaq iv80 going 130km/h on highway so cca same as you. That's 2 hours of driving and 1 hour of charging on 150kW+ charger.

And not to mention the epidemiological aspect, hello covid. A compromise situation could be individual transport but much smaller than current cars. Because EV's scale much more easily than ICE technology it's practical to have EV's with, say, a three person occupancy that take up half of a current car lane. This is the best of both worlds. Single occupancy vehicles and a city's transportation infrastructure doubles at zero cost.

There's a lot of ways to describe commuting in traffic jams, but the word "comfort" is probably not in the top ten.

EVs make substantially less of that, due to regenerative braking.

What portion of drivers use one pedal?

Most EV drivers, I’d say. My sample size is small, but me and my friends who have EVs all drive with one pedal.
