One of the problems is, Audi is VW. Its the same company group, the same managers, the same mindset. This corporate group has zero credibility any more. They lied to regulators, they lied to customers. All the management knew it. A lot of engineers and workers knew it. Nobody, not a single employee within that company group, stood up against the scam going on with their diesel engines.

They've a lot of reasons not to build the e-tron, to delay it or to limit production quantities or to limit demand by expensive pricing. VW is stockpiling newly produced ICE cars on a large airfield currently (
Berlin: VW parkt jetzt auf auf BER-Flughafen - Parkplatznot!), because they did not yet receive regulatory approval. This stuff needs to be sold soon. VW/Audi/<insert group nameplate> have tons of other problems to solve. 99.5% of their lineup are ICEs, a lot of them don't have sales permission currently. They have absolutly no interest in a fast EV success, as they still need to sell lots of ICEs to survive in the years to come. An EV buyer doesn't come back to ICEs. They know that. They want to prevent their customer base from that move as long as they can. That new CEO needs to firefight, influence politics, prevent other lawsuits, fight against more demanding emmission standards, declining market share, production capacity movements and tons of other crisis management. He cannot focus on EVs at this time, because the companies depend on ongoing and vast numbers of ICE sales that need to continue for the next years to come. In such an environment, e-tron production ramp up will get low priority as a result.
