In total, we exceeded our previously announced guidance by delivering 101,312 Model S and X vehicles in 2017. This was a 33% increase over 2016.
In addition to Q4 deliveries, about 2,520 Model S and X vehicles and 860 Model 3 vehicles were in transit to customers at the end of the quarter. These will be counted as deliveries in Q1 2018.
Q4 production totaled 24,565 vehicles, of which 2,425 were Model 3. As we previously indicated, we slightly reduced Model S and X production in Q4 because of the reallocation of some of the manufacturing workforce towards Model 3 production, which also caused inventory to decline.
During Q4, we made major progress addressing Model 3 production bottlenecks, with our production rate increasing significantly towards the end of the quarter. In the last seven working days of the quarter, we made 793 Model 3's, and in the last few days, we hit a production rate on each of our manufacturing lines that extrapolates to over 1,000 Model 3's per week. As a result of the significant growth in our production rate, we made as many Model 3's since
As we continue to focus on quality and efficiency rather than simply pushing for the highest possible volume in the shortest period of time, we expect to have a slightly more gradual ramp through Q1, likely ending the quarter at a weekly rate of about 2,500 Model 3 vehicles. We intend to achieve the 5,000 per week milestone by the end of Q2.
We're very grateful to everyone at
Our 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. Final numbers could vary by up to 0.5%.
