Tesla Motors has delivered a total of 14,820 cars in the first quarter of 2016.

The number represents an increase of almost 50% compared to Q1 2015 and helps Tesla Motors stay on course to deliver 80,000 to 90,000 units in 2016. Deliveries were hampered during the first quarter of the year by supplier parts shortages for the Model X in January and February. Tesla says these took longer than expected and once the problems were sorted out, production and delivery rates “improved dramatically.”

Tesla Motors admits that one of the main reasons that caused the parts shortages is the company’s “hubris in adding far too much new technology to the Model X in version 1.” “Hubris” is basically a fancy term for saying that Tesla overestimated its capabilities to cram a lot of technology in the Model X and have all the necessary components ready for production in a timely manner.

The electric car manufacturer also says insufficient supplier capability validation affected production and consequently the number of cars that were delivered in Q1. Tesla goes on to specify it did not have enough internal capabilities to make the Model X’s parts in-house to speed up the manufacturing process. These components represent only half a dozen of a total of more than 8,000 unique parts that are not shared with the company’s other car, the Model S.

The good news is Tesla says a fix is in the works for all these issues to make sure the situation will not be repeated with the Model 3 that will start reaching customers towards the end of 2017. Tesla Motors had more than 276,000 orders registered for the Model 3 as of Saturday night and we won’t be too surprised if the number will hit the 300,000 mark by tomorrow night when Elon Musk will issue the last update concerning the amount of Model 3 pre-orders.

Since we’re on the subject of orders, the ones for the Model S went up by a massive 45% in the first quarter of 2016 compared to the same period of last year. Q1 deliveries stood at 12,420 units (up from 10,030 in Q1 2015) for the Model S and 2,400 units (up from 208 in Q4 2015) for the Model X, bringing the grand total to 14,820 vehicles.
