Hot Hatch Challenge

Hot hatch challenge

OnGrid created the Hot Hatch Challenge (HHC) to cater to the growing popularity of the boosted hatchback platform. As an increasing number of drivers in the track community move into the driver’s seat of these power-punching rockets we set out with the goal to launch a series specifically for them. In 2019 you can now participate in the series all throughout California testing your Hot Hatch and personal skill against other drivers. We are excited to see this series evolve, just like the drivers competing in it.
