elite hectorx did it with 5505/5052 after a few tries at 0505/5052 but the final ai is on san diego harbor which acceleration upgrades make a big difference because of all the jumps and air speed tricks you can do.Rev_ghost said you can do it 5505/5050, and i heard somepeople saying its really easy at 5505/2222. honestly just save a few tokens and auto test it you can get to 5505/3050 with all the cards in the r&D alone but just save tokens and auto test the last ai if you really want the car and not sure if you can do it the auto test cost is 2400 but you get 150 tokens from completing the challenge and another 500 tokens + double credits in mastery so the net loss is only 1750
