    I’m totally with you on the charging (and don’t have one myself) but as for the drivetrain, is one really that much more efficient than another? There’s not a lot of energy lost to heat, noise, and whatever else that ICEs have. Most of it is in (for example) the body’s aerodynamics, no? And as far as how long they last, most of them are about 10 years old, tops? Hard to judge that one just yet (yeah, the Leafs suck already but they don’t have a battery management system)

      There are a lot of variables that affect it, but Tesla do extremely well here with things like the octovalve and heat scavenging for their AC system. Combine this with the relatively high fast charging speed means range gets added back quickly. About the only company that’s competitive in terms of efficiency and charging speed is Hyundai/Kia at the moment.

      You can compare similar cars here. For example:

      Sedans: Tesla Model 3 RWD: 137 Wh/km Hyundai Ioniq 6: 148 Wh/km Polestar 2 SR: 172 Wh/km VW ID.3: 166 Wh/km BMW i4: 156 Wh/km

      SUV: Telsa Model Y RWD: 164 Wh/km Hyundai Ioniq 5: 183 Wh/km VW ID.4: 177 Wh/km BMW iX3: 192 Wh/km BYD Atto3: 183 Wh/km
