Okay, well another way to think of it is that tesla has proven their choices for amount of usable battery to offer succeeds with half a million + cars on the road and billions of miles driven. Their battery warranty is excellent and time proven. My S is 4 years old and approaching 50k miles and no appreciable degredation. If an S and an etron has about 85kwh there's something to compare there.

Comparing to these other 2 companies, they are being way more conservative, or more likely they don't have as good a battery managment system and they are afraid of big costs down the line if the batteries do degrade. Either way, Tesla has a time tested much better system that provides much longer range with similar overall battery capacities.

It's not that audi can't do better. Just at this time Audi & Jaguar suffer tremendously in comparison.

Yes, that’s a fair way of looking at it. Will be interesting to see what happens with the MEB cars, you’d think there would be a lot of effort there to work on a really solid thermal management system, and much easier to extrapolate data from one model to another.
