The "low-center drive" required development of hypoid gearing, versus the spiral bevel gearing used when the drive pinion axis intersects the axle axis. The strength benefits mentioned in the video come from the hypoid gearing, at the cost of efficiency. AFAIK there isn't currently open-source CAD tooling for designing hypoids. https://en.wikipedia.org/wiki/Spiral_bevel_gear https://en.wikipedia.org/wiki/Spiral_bevel_gear
