According to detailed calculations by Jon Stewart (Cleanerwatt), the all-new Tesla Semi is twice as efficient as the Ford F-150 pickup truck. Keep in mind, a Class 8 semi-truck weighs in at four to five times that of a gas- or diesel-powered F-150.
Tesla is known for producing some of the most efficient vehicles on the road today, and the most efficient cars ever built. While a few rivals have come to market with similar successes, most other EVs aren't nearly as efficient as Tesla's, they have less driving range, and they'll cost you more to fuel.
