The author says his average mileage is 184Wh/km. I've seen similar numbers in other sources: about 200Wh/km. I am an avid cyclist. When I output 200W for an hour I can go 20-30km depending on the terrain. Maybe 15 if it's steep uphill all the way. Cyclists are not very aerodynamic. They sit high and have boxy shape. A small vehicle can be much more efficient (the reason recumbents beat standard bikes on a track). It…

Wouldn’t you rather want to compare manually operating a bicycle to an electric bicycle? They’ve basically taken over China for more than a decade now, so it’s not like they are uncommon.

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

What portion of drivers use one pedal?

You don't need to have the one pedal driving enabled to reap the benefits. In all EVs and PHEVs you brake with the electric motors first even when using the actual pedal - normal brakes are engaged only past a certain threshold.

Also to give a personal anecdote, in my Volvo XC60 PHEV, I've just had the inspection done and after 24k miles the brake pads are 5% worn. That's insane for a 2.2 tonne SUV with 400bhp. If it wasn't a PHEV I can guarantee that the pads would be nearly worn by now.

I charge my Bolt EV to 100% every day. Most manufacturers provide some headroom so rated capacity is less than actual and you aren't hitting 100% SOC, just what the car reports. What the OP also omits is that you gain range during fair weather. My Bolt EPA rating is 255 miles, but I've gotten 303 miles in the summer and as low as 191 in the winter.

This is the first time I've heard anyone exceed their EPA range. 303 miles is impressive!

Most of them as far as I can tell. It’s one of the main buying points to getting an EV.

That's a fantastic way to crater your cars resale value.

How so, exactly? There's no way for anyone to check how much a battery was charged regularly, just like there's no way to check if a car was only used to drive to church once a week or driven like a hooligan hitting redline all the time - I'm not suggesting fraud of course, far from it - just that buyers have to assume the worst possible use case, and if so I don't see how actually regularly charging the battery to m…

I believe the SoC (state of charge) history is recorded for Teslas and other EVs. There is a company called Recurrent [1] which uses this data to estimate battery degradation. I think the idea is to generate something like a Carfax report for used EV battery packs.

Or just read the article and realize that the author doesn’t fully charge their car?..

Tesla advises 90% max, other sources advise charging to 80% to save battery performance. I use 80% for day-to-day, 90% for longer day trips, 100% for international travel. [tesla.com/support/home-charging-installation/faq]( https://www.tesla.com/support/home-charging-installation/faq )

I am aware of that. I charge my Tesla to about 50-70% as most of my infrequent trips are short. But I also don’t write articles complaining about low mileage.

Interesting that driving style has such an outsized impact. Perhaps aggressive driving and tire composition should be regulated.

or tax tires

If you look outside of the USA lots of cities have good public transport systems that aren't plagued by poverty, crime, homelessness and mental illness. Just because Americans have decided to optimize their society to maximize misery of a minority for the benefit of an even smaller minority doesn't make it necessary.

Western European countries are also much stricter on law and order via transit. Brussels, for example, deploys heavily armed police to check fares on the metro often. And Switzerland…you really don’t want to break the laws there even if you have nothing to lose.

"Cold weather has an influence on the battery capacity too." I take this to mean that the author acknowledges GAS cars are also affected by cold weather. There's just no escaping thermodynamics. It's also like pointing out GAS cars' MPG is reduced by 20%+ in cold weather. While it's true, it's like pointing out a gotcha edge case for all cars. So the conclusion can also apply the same way to GAS cars. 'Next time you…

Actually I wasn't referring to ICE, just that the climate influenced the realistic daily range too. But your remark is very interesting, I would have thought that combustion did not suffer much from the cold.

So you deliberately don't charge the battery to 100% then conclude the realistic range is shorter than advertised? I get you don't charge to 100% every day, but if you know you're going to drive further then....you do. Or just do what I do and charge to max each time, the battery is warrantied for 8 years, it's going to be fine. >>Imagine your daily commute is 115 km (e.g. Roeselare-Brussel That would be an extremely…

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.
