The only legacy OEM that has really tried/been forced to go EV realises the difficulty in catching up to Tesla and thinks buying them is the only way to compete.Note that that's not exactly a denial either. It might be pure speculation and still be true.
Manager Magazin had high level VW leaks in the past too, such as these details about VW's internal targets and costs:
I have the impression that this leak was a trial balloon by VW top management - in part to pressure Elon, in part to sound out the opinion of the big Volkswagen shareholders.
The problem with buying Tesla is that you have to pay the with Elon price but only receive the ex Elon value.
