As I posted in the "Demand" thread the reintroduction of the referral program could be seen as a bullish signal:
It may be a demand levers being pulled to increase demand right now because they know that within 4 weeks MX ramp talkes off and total production capability (S+X) increases significantly. And they want to stay at a point of optimum lead time.
Exactly. Just to add, the Q1 shareholders letter included guidance for production increased in second half of the year to above 2000 cars per week. The referral program is probably designed to increase the rate of incoming orders to match increased production output due to completion of the ramp in production.
"Importantly, now that supply chain constraints have been resolved, we plan to exit Q2 at a steady production rate of 2,000 vehicles per week, thus laying the foundation for a strong Q3 delivery number.
Looking out beyond Q2, we remain confident that we can deliver 80,000 to 90,000 new Model S and Model X vehicles in 2016. This
is due to the growing demand we are seeing for Model S and Model X, the improved rate of production that we project for Q2, and
the production increases planned for the back half of 2016."
