When the P100D was announced, Elon promised that: "Tesla customers who have ordered a P90D Ludicrous, but not taken delivery, can upgrade to the 100 kWh pack for $10,000..." so I'm curious to hear whether any P90DL owners that are eligible, have actually managed to get this upgrade done? I'm an eligible owner (ordered months before the announcement; took delivery about a week after the announcement). Before I received the car, i explicitly asked my D.S. about this and he confirmed I was eligible, but said the upgrade would take place "early in the New Year". Now, six months later, I'm still waiting. The latest news - from the Tesla Europe director himself - is that any upgrades (in the UK at least) won't be happening until at least Q3 2017 - that's nearly a year after I bought my car. It's not as if the 100 kWh battery packs are in short supply: Tesla's now selling them in non-performance models. So why the delay? - or is it that they're stalling and don't really want us to have the new packs?
