BD's machines actually have terrible energetics. They use very heavy and inefficient hydraulic actuation. I can't find a source for it, but IIRC Atlas has a specific resistance of around ~40, compared to a human which is around 0.2. I don't know an RC Car is at, but direct drive motors are quite efficient.

Whatever BD's angle is, it's not efficiency.
