Production of Tesla's next vehicle, the Model X crossover was supposed to kick off sometime later this year, but Tesla has now pushed back the Model X's introduction until the second quarter of 2015. This is not the first time the Model X has been delayed, since it was originally slated to arrive in early 2014.

Tesla is still hard at work on the Model X and it expects production prototypes to be ready by the end of the year with production expected to kick off by next spring. The Model X shares its platform with the Model S, but will only be offered with all-wheel-drive. The Model X will be offered with a 60 or 85 kWh battery and Tesla estimates that the standard Model X will reach 0-60 mph in 4.4 seconds. Tesla has yet to announce the pricing for the Model X.

Part of the reason that the Model X is being delayed is because of battery supply issues, which will soon be resolved with the launch of Tesla's new Gigafactories. By 2020 Tesla estimates that the Gigafactories will reduce battery costs by 30 percent and help it produce 500,000 vehicles a year. Tesla hasn't confirmed where the battery factories will be, but the first of the two factories is going to break ground next month. Arizona, Nevada and Texas are reportedly in the running and there's a chance that California could also become home to one of the Gigafactories.
