Tesla says it delivered 11,500 electric cars globally from April through June

Keeping to its promise of releasing quarterly global sales totals in a timely fashion, Tesla Motors announced its second-quarter delivery totals this morning.

According to the Silicon Valley carmaker, it delivered 11,507 Model S luxury electric cars from April 1 through June 30.

That is its highest quarterly total thus far, and brings Tesla’s global deliveries for the first half of 2015 to 21,537 cars.

Tesla’s release, in its entirety, reads:

Today Tesla Motors announced 11,507 Model S deliveries for Q2-2015.

This was a new company record for the most cars delivered in a quarter and represents an approximate 52-percent increase over Q2 last year.

There may be small changes to this delivery count (usually well under 1 percent), as Tesla only counts a delivery if it is transferred to the end customer and all paperwork is correct.

Also, this is only one measure of our financial performance and should not be relied on as an indicator of our quarterly financial results, which depend on a variety of factors, including the cost of sales, foreign exchange movements and mix of directly leased vehicles.

The company did not, however, break out those deliveries by market, leaving it unclear how the Tesla Model S fares in sales against the three other high-volume plug-in cars in U.S. sales.

Those are the Nissan Leaf — by far the world’s best-selling electric car, with more than 180,000 delivered as of late June — the Chevrolet Volt range-extended electric car, and the BMW i3, which comes in battery-electric and range-extended versions.

The Model S base price is more twice that of either of the Leaf and Volt, but Tesla Model S sales in the U.S. are likely somewhere between 600 and 1,200 per month, putting it among the top four.

Tesla CEO Elon Musk previously said the company’s sales goal was 55,000 for the full calendar year.

If Model S global sales stay steady for the balance of the year, that would indicate that it expects to deliver roughly 12,000 Model X electric SUVs.

That may be an ambitious goal, given that the completed car still hasn’t been shown in public, and any kind of volume deliveries would only begin in October or later.

Tesla refuses to release monthly sales numbers, either globally or by market, as other makers do.

It began releasing the global totals by quarter in April because, it said, the company believes “inaccurate sources of information are sometimes used by others to project the number of vehicle deliveries.”
