Anyone that’s seen a Model S knows that its retractable door handles is a masterful piece of engineering, for better or worse. Walk up to the car and the door handles greet you by surfacing themselves from within the door. Walk away and they automatically retract. The flush mount design of the door handles not only has a super cool factor to it, but also allows the vehicle to maintain one of the lowest drag coefficients of any production car available. Low drag means better aerodynamics which means better range.

The Model X is no different in the sense that it has a flush mount handle and is self-presenting, but here’s the big difference. What’s self-presenting isn’t the handles. Rather, the entire front door of the Model X automatically swings open making for truly frictionless entry into the vehicle.
