In Q4, we plan to build 15,000 to 17,000 vehicles, and deliver 17,000 to 19,000 vehicles, which will result in 50,000 to 52,000 total deliveries for the year.
Model S production and deliveries are on track to achieve our initial Q4 plan. The primary limiting factor to higher Q4 deliveries is the near term ramp of Model X production, with the biggest constraint being the supply of components related to the second row monopost seats. To eliminate these supply constraints and achieve a better overall outcome, we have brought manufacturing of these seats in-house. In addition we, and some of our other Model X suppliers, are still ramping up and fine-tuning production. These factors add uncertainty to our build plans during Q4, but we feel emphasizing quality is the right decision for our customers.
We expect that Model X will achieve steady state production capacity during Q1 as we do not foresee any significant production, design or supply chain constraints that will impact this plan. Looking ahead, we still remain highly confident of average production and deliveries of 1,600 to 1,800 vehicles per week for Model S and Model X combined during 2016.
