"It's not the only reason, though. It'll be lots of fun racing a high horsepower car in an arena-type venue.
"It'll also help me develop my driving in a way, as you can never have too many tools in the tool box.
"The new thing for me will be having to race other drivers. There might be a bit of door handle banging as well. Whenever I go karting with my mates, it sometimes ends in tears, as if I see a gap half the size of the kart, I still go for it.
"I'll also be keeping my foot in the door in an effort to get back into the WRC."
All 12 drivers are in identical PanetraRX6 cars and all have a considerable amount more experience in these cars and this format than Paddon. He's not fazed by this, though, and is hoping his natural competitiveness will keep him at the pointy end of the field.
He tested with a few other drivers at Fuglau, Austria, in May and was impressed at how easy the car was to drive, how agile it was and that it had a decent amount of horsepower.
"It's a very competitive field, so it will be tough. I'm hoping it's something I can learn and pick up on quickly, but essentially, I'm going in with zero expectations and just see how it pans out.
"I'm sure it will be a lot of fun. It will be interesting racing five other cars at the same time in the short rallycross races, and of course I'll be driving as hard and fast as I can," he said.
