Aero matters a lot more than weight on a Tesla.
Ever notice how Teslas get crushed EPA range vs. actual when doing long highway jogs? And how when doing long highway jogs, others meet or beat their rated range? Tesla drivetrains are SO efficient that their aero load is by far the biggest killer. Other less efficient EVs aren't as hit as much, as an overall percentage, by areo.
This is why an ICE, with a super inefficient powertrain, sees MORE economy on the highway than around town. The increase in the engine's efficiency way more than makes up for the aero load. Which is an even greater overall aero load than a Tesla, which is far more wind efficient.
Read that again and think about it.
