Tesla Inc, the US luxury electric car maker, said on Sunday first-quarter vehicle deliveries jumped 69 percent from a year ago to a quarterly record of 25,000 vehicles, bouncing back from delays in the previous quarter.

The company said of the total vehicles delivered, about 13,450 were Model S sedan and about 11,550 were Model X sports utilityvehicle.

Tesla has said it expects to deliver 47,000 to 50,000 Model S and Model X vehicles combined in the first half of 2017.

In the fourth quarter, deliveries had fallen 9.4 percent due to short-term production hurdles from the transition to a new

autopilot hardware.

Tesla had said production challenges, which started at the end of October and lasted through early December, shifted vehicle production towards the end of the fourth quarter, resulting in delayed deliveries.

Ultimately, about 2,750 vehicles were missed being counted as deliveries in the fourth quarter either due to last-minute delays in transport or because the customer was unable to physically take delivery.

In addition to the first quarter deliveries, about 4,650 vehicles were in transit to customers at the end of the quarter and will be counted as deliveries in the second quarter, Tesla said in a statement on Sunday.
