This off-cycle technology is available for purchase to help improve aerodynamic fuel efficiency and gain off-cycle credits.

Their website apparently doesn't define 'off-cycle technology'. Which may or may not be different to 'aftermarket parts'. Despite the marketingdroid-speak they do have some interesting technology in 'adjoint':

Shape optimisation takes the exterior of a car, for example, and shows whether you should push or pull on the surface to improve a given parameter, or set of parameters (drag, downforce, efficiency, balance, etc.). This delivers in a single run what would take many hundreds, or thousands, of CFD runs to deliver using traditional parametric techniques.
