Along with the news that Tesla expects to build 80 Model S electric cars this week, CEO Elon Musk also released a few more details of the company's plans for additional models in 2016.

Tesla Motors [NSDQ:TSLA] has already said that it will launch the Model X crossover within the next year or so.

That seven-seat crossover utility, complete with roof-hinged "falcon doors," is to be built on the same basic understructure as the Model S all-electric sport sedan.

Now, Musk told Wired last week, the company's third vehicle architecture--a smaller, less costly vehicle than those two models--will include not only a sedan, but also a smaller crossover and a sports car.

The sedan is expected to be roughly the size of a BMW 3-Series, so the crossover might logically be comparable to that company's X3 crossover utility vehicle.

And the sports car effectively replaces Tesla's very first car, the 2008-2011 Roadster electric two-seat convertible.

The previously announced entry-level sedan, to be a 2015 model, is targeted for a price before incentives of about $30,000.

That's little more than half the cost of the Model S, which starts at $57,400 but can approach a sticker of $100,000 if the largest battery pack, for the longest range, and other options are selected.

The sedan will actually be a five-door hatchback, as is the Model S, Musk told Wired.

He called it a "scaled-down Model S," saying it would be "20 to 25 percent smaller" than the current Tesla sedan.

For the moment, though, Tesla has to work through the challenges of scaling up production of the 2012 Model S, the first production car it's assembled itself, to volumes of 80 cars a day.

First things first ... though it's nice to have a sense of what Tesla would like to do over the next several years.

You can say one thing: Tesla and Musk don't lack for ambition.
