Right now, all eyes are focused on Tesla's (TSLA -1.06%) Model 3, which has always been the end goal of Tesla's grand plan. Starting at $35,000 before incentives, Model 3 has always promised to be the electric automaker's mainstream EV that appeals to the mass market. For context, the average transaction price before incentives in March for a new vehicle in the U.S. was $33,666, according to Kelley Blue Book.

But there are still plenty of consumers that can't or won't pay that much for a new vehicle. Tesla has a plan for that market segment, too.

Fourth time's the charm
Tesla's product roadmap has always consisted of three vehicle platforms. The first was the Roadster, although those were built by hand so there wasn't an actual manufacturing platform. The second includes Model S and Model X, and Model 3 will be built on the third-generation platform. After Model 3 will come Model Y, also built on the same third-generation platform (even though Tesla doesn't really talk about Model Y much these days).

It turns out that the company is already planning its fourth-generation platform. Tesla CEO Elon Musk recently attended the Future Transport Solutions conference in Norway, and Musk sat down with Norway's minister of transport and communications for a brief discussion. This was also where Musk dropped other hints about a potential future Tesla mobility service. Here's how he referred to the fourth-generation platform:

I'm super excited about being able to produce a car that most people can afford. And there will be future cars that are even more affordable down the road. But with something like the Model 3, it's designed such that roughly half of people will be able to afford the car. Then, with fourth generation and smaller cars and whatnot, we'll ultimately be in the position where everyone will be able to afford the car.

Musk didn't elaborate any further in terms of specifications or pricing, but you can imagine Tesla potentially targeting a price point in the neighborhood of $20,000 next. That would be a strong offering and would dramatically accelerate EV adoption even more. Meanwhile, we already know that Musk wants to do an electric truck at some point.

Between Model 3, Model Y, an electric truck, and a fourth-generation EV, Tesla will have its hands full for quite some time.
