Has Elon Musk Cut Tesla's 2015 Electric-Car Guidance A Bit, Maybe?

After the New York financial markets close this afternoon, Tesla Motors will release its first-quarter financial results and its quarterly letter to shareholders.

The company announced last month, just after the close of the quarter, that it had delivered about 10,300 Model S electric cars.

At that time, the company's "guidance" (or informed projection) for its full-year deliveries in 2015 was 55,000 vehicles.

That number represents a two-thirds increase on the 33,000 Model S cars it delivered for all of 2014.

The increase for 2015 includes not only the latest P85D and 70D all-wheel-drive versions of the Model S, but also some unknown quantity of sales of its upcoming Model X.

That electric SUV is scheduled to start deliveries in the second half of the year, though Tesla has not yet shown its final production version to the public.
