I'm surprised by the reaction to this article. 1. The range is set by the EPA. They are the ones that do the testing and validate the claims. The EPA should fix their range guidelines for EVs. Maybe a summer and winter range would be more appropriate? 2. Tesla should have a better UI for range, but really they should just show the percentage. Acting like it is a conspiracy is a bit extreme. They are just doing EPA Ra…

Battery tech has changed a lot since 2008.

I don't think so, cold and cycle degradation still impact range the same. Maybe battery heaters?

Giving optimistic estimates based on generalized vehicle information, then giving more precise estimates after the 50% mark—and after having collected usage information based on the user’s actual environment—sounds to me like a decent algorithmic solution to a hard problem.

It sounds like a terrible solution to an easy problem. And calling it an "algorithmic solution" is being generous, considering that our dead simple decade old Mazda 2 gives us a closer than 25% range estimate just based on the mpg for the previous X number of miles driven. That's not an algorithm, that is a simple math calculation with only two inputs; gas consumption rate and miles driven. Tesla, with thousands of d…

Consumer Reports and others have found that most of the "issues" reported with EVs in these rankings are software glitches , often solvable with a reboot or an over-the-air software update: https://www.greencars.com/expert-insights/are-electric-cars-... Those findings are consistent with my experience.

“The organization also found that Tesla, which is often lauded for its sophisticated technology, was not a paragon of reliability, ranking dead-last among brands”

Your second sentence is correct, but it takes a lot more torque to turn a generator at a given speed when it is driving current through a load, than it does when it is open-circuit. Inside the motor/generator, what happens is that if there's current flowing in the windings as a result of the EMF induced by turning the rotor, then, loosely speaking, it creates a magnetic field which opposes the rotation - but if it is…

Correct me if I'm wrong but, if I understand things correctly... at this point we're wondering if manual locking hubs are a better (or worse) solution than electrically isolating the motor(s). Right? And, off the top of my head I'm going to say the manual locking hubs will be better overall. Better from an energy efficiency perspective as well as overall convenience and simplicity of design. They might be worse for T…
