1700 tokens. But I highly recommend doing the R&D. Even with 50 tests, it's still pretty easy. The only hard part is the last 10 tests (excluding test 50). The upgrades on the Alfa Romeo 4C is quite cheap, and you can earn free tokens from the lab itself. I used only 48 tokens in the entire lab, which was awarded back when I cleared challenge 50 (and got 50 tokens). I basically not only got a free car, but I also gained a lot of tokens (and credits). So I highly recommend that you do the R&D first.
