Tesla (tsla) CEO Elon Musk has announced that the electric car company will unveil its first semi truck in September, followed by a pickup truck model in close to two years’ time.

Plans for an electric transport vehicle have been anticipated since Musk revealed the second part of his “master plan” for the Palo Alto-based automaker in July last year.

Musk wrote in his blog then that the company would step beyond the car market and begin work on self-driving semis, pickup trucks and buses.

The commercial truck will be followed by a pickup truck for the consumer market in “18-24 months,” Musk subsequently tweeted.

On Monday, Tesla overtook General Motors (gm) to become the most valuable automaker in the United States.
