Alright, here's a tricky one. For existing P85D customers who "only" have INSANE and are interested in upgrading to Ludicrous, my understanding is that there are 2 options: A. Upgrade the contactors/fuses/etc to get Ludicrous mode only, keeping 85 kWh battery capacity B. Upgrade contactors/fuses AND upgrade to 90 kWh capacity at the same time If one was to choose option A, but was then interested at some point in the future (1-2 years later) in upgrading battery capacity to say, 95 kWh, would the Ludicrous upgrade be retained? Also, would you speculate that this will be a cheaper or more expensive option than not upgrading at all now, and waiting to upgrade both power and energy (Ludicrous + 95 kWh) at the same time later? I know a lot of this is unknown for a fact at this point, I'm just interested in getting different opinions.
