Do you have a source for this? I ask because manufacturers can't use aerodynamic features on their cars unless they sell more than two thirds of those cars with the aero feature.

So... Either Tesla is quoting the EPA range with the Aero wheels even though they know the actual EPA range with the sport wheels will be lower, or they're quoting the EPA range with the Sport wheels and the actual range with the Aero wheels will be higher.

Edit - They can also create another category for vehicles sold with the aero features, but last I checked there was just one CARB executive order for the Model 3 Long Range, and I believe the test group from the CARB EO is the same as the test group used for EPA certification, which implies Tesla is only going with a single test group for now.
