As Tesla is a public company, I do have an idea what their finances are. It's their decision to pay the billion dollars off using cash on hand just like it is their idea not to use cash to purchase Maxwell. Paying off the loan does not affect their i&e.
As they just started shipping Model 3s overseas, there is a delay of receiving income which is why they may have a loss in Q1 but that is exactly my point; they are focused on the financials for this quarter instead of their long term viability.
If you knew that Tesla was going to go bankrupt, would you lend them money or buy their cars? Financials of a debt-laden company affect lender and consumer confidence.
They worked through US demand at $7.5k tax credit. They used the MR to try to upsell some more. That's clearly done. They've been selling 6k per month for the past 2 months, which isn't enough for Tesla's structure, which is built on high volume.
On top of this, the reduction in tax credit, plus the availabliity of both Model 3 and competitors' luxury long-range BEVs is also reducing the S and X markets.
So SR is here. Tesla has had to do everything they can to reduce overheads to be able to release it profitability. Model 3 is now decidedly an entry-level premium car, and the option pricing reflects the $42k ASP of that segment.
The PUP is broken up to offer an upsell to the SR buyers who deal more with cold, so want heated seats and will benefit from a bit more range.
Autopilot is back to the same key features and $500 more than it was when the Model 3 was launched 3 years ago, because $5k for the usable features that are now becoming widely available across the industry isn't going to get much take.
SR + Partial Premium + AP + Color
= $35k + $2k + $3k + $1.5k
= $41.5k
