I had one of the older go pros and it was grainy at best on a dimly lit dirt track. What is the best brand and model out their now for low light? I am thinking about buying a new one this year and would like some recommendations?

This was taken with a GoPro Hero 3+. I'm sure it's obsolete by now, and the newer ones are even better.

Gopro hero 4+ black edition is excellent in low light. the replay xd action cam is also very nice.
