WattEV has committed to purchase 370 Tesla Semi Class 8 trucks for operations in California, representing the largest single order of electric heavy-duty trucks in the state. The deal underscores growing corporate demand for zero-emissions freight solutions as companies transition large fleets away from diesel units.

This order enhances Tesla's Semi production outlook by adding substantial volume to its commercial vehicle backlog, supporting production ramp efforts at its Nevada Gigafactory. The record deployment offers clear revenue upside and reinforces Tesla’s position in the emerging electric truck market.
