Tesla has revealed that it delivered 14,370 electric vehicles during the second quarter of this year, a figure that's a bit lower than expected due to what the company describes as an extreme production ramp and the fact that many customer-ordered vehicles were still on trucks and ships at the end of the quarter.

For the quarter, Tesla delivered 9,745 Model S sedans and 4,625 Model X SUVs. Tesla said 5,150 customer-ordered vehicles were still in transit and should be delivered early in the third quarter. In comparison, only 2,615 vehicles were in transit to customers at the end of the first quarter.

As Electrek points out, this is the first time in Tesla's history that it has experienced a decline in deliveries two months in a row.

Tesla produced 18,435 vehicles in the second quarter, a 20 percent increase compared to the first quarter. Due to the production ramp, nearly half of the quarter's production occurred in the final four weeks, we're told.

Delivery data suggests that Model S demand has plateaued. Considering the overwhelming demand for the upcoming Model 3, it's entirely possible that prospective Model S buyers are instead opting to reserve the more affordable electric sedan. Without order numbers, however, it's hard to say that's the case for sure.

Looking ahead, Tesla expects to produce and deliver roughly 50,000 vehicles during the second half of 2016 which would come close to equaling 2015's total output. Come the fourth quarter, the company expects to churn out roughly 2,400 vehicles per week.

Just last week, the rumor mill suggested Tesla has selected Shanghai as the location for its upcoming $9 billion factory. Getting another production facility built and online is no doubt high on the company's list of priorities as they have a mountain of Model 3 orders to fill.
