I thought the discussion here on the forum was leaning towards all 90 kWh batteries having the hardware aspects of Ludicrous mode in them already. If so, it's just a software switch they could flip when they go to sell it. OTOH, it's true that most of the P90Ds they'd order for demonstraters would benefit from having Ludicrous mode so they could show it off to potential customers, and this might just be a reflection of that. - - - Updated - - - Tesla has a consistent formula for how they discount prices on loaners - I think it's something like a dollar per mile and a thousand per month. While I'd love to buy a car for less money, there's no incentive for them to drop the prices since they are clearly getting plenty of turnover as it stands, especially from gotta have it now impulse buys.
