Gross vehicle weight ratings are the weight of the vehicle plus the cargo that can carried on the truck. Trucks can tow much more weight than can be loaded onto them. Tesla previously talked about a weight of 5000 lbs for the vehicle and carrying 3500 lbs. A 5000 lbs truck that carries 5000 pounds would be at the bottom end of the Class 3. A 5000 lbs truck that carries 10000 pounds would be at the bottom end of the Class 4 trucks. The Cybertruck with Tesla Semi technology like the 1000 volt power system instead of 400 volt and the light weight plaid motors will easily fit and increase the power of the Cybertruck.

The existing diesel-powered supertrucks in Class 4 have larger and stronger flatbeds.

The Class 3 truck gross vehicle weight rating (GVWR) ranges from 10001–14000 lb (4536–6350 kg).
