Tesla produced 24,882 vehicles in Q4, resulting in total 2016 production of 83,922 vehicles. This was an increase of 64% from 2015. Tesla delivered approximately 22,200 vehicles in Q4, of which 12,700 were Model S and 9,500 were Model X. When added to the rest of the year, total 2016 deliveries were approximately 76,230. Our Q4 delivery count should be viewed as slightly conservative, as we only count a car as delivered if it is transferred to the customer and all paperwork is correct. Because of short-term production challenges starting at the end of October and lasting through early December from the transition to new Autopilot hardware, Q4 vehicle production was weighted more heavily towards the end of the quarter than we had originally planned. We were ultimately able to recover and hit our production goal, but the delay in production resulted in challenges that impacted quarterly deliveries, including, among other things, cars missing shipping cutoffs for Europe and Asia. Although we tried to recover these deliveries and expedite others by the end of the quarter, time ran out before we could deliver all customer cars. In total, about 2,750 vehicles missed being counted as deliveries in Q4 either due to last-minute delays in transport or because the customer was unable to physically take delivery. Even where these customers had already fully paid for their vehicle, we still did not count these as deliveries in Q4. In addition to Q4 deliveries, about 6,450 vehicles were in transit to customers at the end of the quarter. These will be counted as deliveries in Q1 2017. Vehicle demand in Q4 was particularly strong. Q4 net orders for Model S and X, which were an all-time record for us, were 52% higher than Q4 2015 and 24% higher than our previous record quarter in Q3 2016.
Tesla experience production delays during the quarter and were unable to deliver the 25k+ cars they had guided for. This is disappointing since many were hoping for Tesla to to "beat" quarterly expectations for a second quarter in a row. However, some of Q4 deliveries will be pushed back to Q1 which means that Q1 is likely going to be a healthy quarter. Further, starting Q1 of this year we are likely going to see the ramp of Tesla Energy products, namely the Powerpack and Powerwall.
