Tesla promises to quickly ramp up Model X production

The company wants to spend just two months to go from the first unit to thousands per week.

Tesla Motors has promised to quickly ramp up Model X production once the first units arrive on the market.

The crossover has already been delayed several times; three years have passed since the first concept was revealed to the world. The company now appears to be sticking with a third-quarter delivery promise, after starting the retooling process last summer.

The Model X will be built alongside the Model S on the same line at Tesla's Fremont factory. The company will be starting crossover production while simultaneously ramping up sedan output to meet growing demand.

It took six months from the first Model S shipments until the factory was producing the car in higher volumes, but CEO Elon Musk wants the Model X to reach the same milestones in just two to three months.

"We're going to go from a few cars to 1,000 a week pretty fast," he said during a recent earnings call.

The company reportedly hopes to double total vehicle output in the fourth quarter, after a few hundred Model X crossovers roll off the line as a "captive fleet" to get every bug ironed out ahead of volume production.

Customers with pre-orders will be able to configure their Model X via an online tool beginning in July.
