alt Hacker News> It’s likely the first non-Tesla vehicle to run FSD, and it achieves 258 Wh/mi — roughly matching the efficiency of an actual Model 3.
This claim is implausible, right? The Mustang is unambiguously less aerodynamic than the Model 3; there's no way it is achieving similar efficiency, especially at highway speeds.

Yes it is implausible. But I imagine that they are probably not running it at 70 mph everywhere, just pootling about in suburbia
The Mustang is from before modern safety laws (and feature expectations) and therefore weighed a lot less than your average modern car.
A stock '66 Mustang hardtop had a curb weight below 3000lb, in the lightest configuration close to 2500lb.
Less mass to move will do a lot for efficiency just like aerodynamics will.
Of course, you will also die or be horrifically maimed in an accident in a 1966 Mustang that you might walk away without any serious injuries from in a modern vehicle.
