They don't commission anyone to build their engines. What crispy didn't touch on is that they completely strip Porsche engines down & rebuild them to their own specs. In general, that may seem to be what a typical tuner does, but the process is extremely in-depth & isn't something done in the time frame a usual tuner will do; they will do numerous tests to make sure the engine produces what they want. At that point, it's not much of the Porsche engine it started life as.Anybody can commission companies like Hartley to produce engines, Ariel is just another example of a bunch of blokes in a shed too, I guess anybody can become a manufacturer after some paperwork
