The new cars will include driver names and manufacturer badges on the windshields.
The Gen-6 car was the main focus, but Helton was asked about the possibility of a road course being included in the Chase for the Sprint Cup at some point.
"We were clear at the outset — and time could change this — but we weren't going to adjust the schedule to fit the Chase," Helton said. "The Chase was an element we added at the last 10 races of the year, and when we did that, there weren't any road courses in that part of our season. I'm not sitting here and saying that will never change, but there's nothing any time soon."
