Musk made his comments on a conference call after the company reported results for the fourth quarter of 2018.
"We might be ready to unveil that this summer," he said of the Tesla pickup. "It will be something quite unique, unlike anything."
Musk has long been considering adding a pickup truck to its lineup. In December, Musk talked extensively on Twitter about what he would like to include in a design, including all-wheel drive with "crazy torque & a suspension that dynamically adjusts for load."
"Pickup truck will have power outlets allowing use of heavy duty 240V, high power tools in field all day," he added. "No generator needed."
The company currently sells two sedans, the high-end Model S and less expensive, but still rather premium Model 3. Tesla also makes the Model X, a three-row sport utility vehicle. It has also unveiled a commercial freight truck, a new version of the high-performance Tesla Roadster, and has plans to have the Model Y crossover ready for sale by the end of 2020.
