(Reuters) - Luxury electric vehicle maker Tesla Inc (TSLA.O) said on Monday its deliveries rose 4.5 percent in the third quarter from the prior-year period, but said "production bottlenecks" had left the company behind its planned ramp-up for the new Model 3 mass-market sedan.
Tesla said it delivered 26,150 vehicles in the third quarter, including 14,065 Model S vehicles and 11,865 Model X cars, up 17.7 percent from the second quarter of this year.
The Palo Alto, California-based company delivered just 220 Model 3 sedans and produced 260 during the quarter. In July, it began production of the Model 3, which starts at $35,000 - half the starting price of the Model S.
Tesla had said in its second-quarter financial report that it expects "to achieve a rate of 5,000 Model 3 vehicles per week by the end of 2017." The automaker also said it expects at some point in 2018 to further ramp to a rate of "10,000 Model 3 vehicles per week," and an annual production rate in excess of 500,000 vehicles.
"It is important to emphasize that there are no fundamental issues with the Model 3 production or supply chain," Tesla said in a statement. "We understand what needs to be fixed and we are confident of addressing the manufacturing bottleneck issues in the near term."
Tesla said it was on track to deliver around 100,000 S and X models this year.
But Tesla said on Monday that a handful of systems at its Fremont, California, car plant and its battery factory in Reno, Nevada, "have taken longer to activate than expected."
The automaker said 4,820 Model S and X vehicles were in transit to customers at the end of the third quarter and would be counted with its fourth-quarter figures.
In after-market trading, Tesla shares fell more than 1 percent to $337.84, from the closing price on Nasdaq of $341.53.
