Fuel Economy and Real-World MPG
The various versions of the Model 3 are rated between 113 MPGe and 141 MPGe by the EPA. Our test vehicle, however, managed only 84 MPGe when we took it on our 200-mile highway fuel-economy test. The Model 3 comes standard with aluminum wheels that are covered by plastic aerodynamic hubcaps. We wanted to know how much impact those hubcaps have on the car’s driving range, so we tested it and were surprised to find that they helped more than expected.
