Mr. Thompson noted the separate series' chassis and body regulations are roughly the same across all four championship series — late-model stock cars using bodies of Chevrolet, Ford and Toyota sedans powered by identical 396-cubic-inch V8 racing engines.
Teams electing to complete in the Elite Series will run the current ARCA engine package, while teams competing in the Pro Series East and West will run the existing package for those series as well.
The revised format will provide a platform for younger, up-and-coming drivers to go head-to-head with seasoned veterans on the same playing field.
"That's the part that excites me the most," Mr. Thompson said, "the opportunity to get those young stars against some of these seasoned veterans and have them all out there at the same time.
"It's a good natural progression from racing among your peers, so to speak, to going against some wily vets, which is what they're going to see in the Truck Series. It's another ode to that developmental ladder and this being a key rung in that ladder."
