In his recently-released "Master Plan Part Deux" for Tesla聽Motors, CEO Elon Musk specifically mentioned a handful of new products.

They included a semi truck and an autonomous bus that would mark Tesla's entry into the commercial-vehicle market, as well as a pickup truck and a small crossover to expand its passenger-vehicle lineup.

Musk subsequently took to what seems to be his favorite forum鈥擳witter鈥攖o confirm a couple of details about one of those models, and hint at yet another new-vehicle project.

The small crossover mentioned in the "master plan" will be聽based on the Model 3, and will be called Model Y, Musk tweeted in response to a聽Road & Track听补谤迟颈肠濒别.

Musk also confirmed plans for a Tesla "minibus" based on the larger Model X afterJalopnik聽published an article theorizing about such a vehicle.

"The Tesla Minibus will be built on a Model X chassis. People density potential is surprisingly high,"聽Musk tweeted in response聽to the聽Jalopnik听补谤迟颈肠濒别.

Musk has referred to the聽vehicle聽as a "Bus/Minibus/Spacebus."

One word Musk almost certainly will not use to describe this vehicle is "minivan," because that would likely compromise Tesla's carefully-cultivated image of coolness.

Whatever segment the company classifies it in, a Model X-based minibus could be a rival to an anticipated聽all-electric revival of the classic Volkswagen Type 2 bus,聽Jalopnikspeculated.

There have been numerous rumors about an聽electric聽VW bus, and the company unveiled the Budd-e electric van concept at CES earlier this year.

The Budd-e was based on Volkswagen's new MEB platform for compact electric cars, meaning a production version would likely be smaller than a Model X-based bus.

The Tesla minibus could also support the company's plans to make car sharing a major part of its business.

In the second master plan, posted on the company's blog, Musk said Tesla will make future self-driving cars the basis of a car-sharing service, with a fleet comprised of both customer and company-owned聽vehicles.

Under the proposed scheme, Tesla owners could rent out their cars when not needed, and Tesla would provide additional cars to create an adequate-sized fleet.

With its greater passenger and cargo capacity, a minibus could be quite useful in such a service.

Of course, Tesla has many projects already underway, so it's unclear when the company would actually get around to launching this new vehicle.
