Tell that to all the people who cancelled their Taycan orders once range numbers came out. Wonder what % did cancel, as JeffKeryk reported above?

VAG can't hide it. .... Its there for all to analyze. .....The problem (high heat loss, lowered efficiency) areas are found with Munro (

Basically, watts in, then compared to watts out, of any individual component tells you
where the losses are. For example, watts measured entering the motor (volt x amps), compared to torque x omega (watts) at the output shaft. Power modules similar, or else try to measure heat dump.
Uncovering the internal
WHY is another matter. Somebody (Munro?) can take apart the motors side by side with a Tesla and tell us how advanced they are or not. It'll happen I'm hoping. ...
Even little things like whether or not VAG is using SiC MOSFETs or not can affect this. Actually, the structure might be more important. EE experts would know is about all I'm saying.
If you haven't seen a
basic energy usage analysis on EVs, see
