NASCAR completes first day of Next Gen testing

Over 600 laps have already been logged by teams at the Charlotte Roval more than halfway through the first day of Next Gen testing, and NASCAR’s John Probst said everything is going well.

Or as well as they can be as teams and officials continue to work through a new car. Updated suspension parts and pieces are on the cars for Monday and Tuesday after earlier tests and a safety test. These include an updated softened structure for the front and rear clip, as well as different ideas to help with the heat inside the cockpit.

So far through the first day of testing, Probst, NASCAR senior vice president of racing innovation, did acknowledge teams are working through steering issues. Some have experienced vibrations, which have been attributed to the set screws. However, he said it is not unusual to have to deal with that in a new car.

The Nos. 8, 18, 19, and 48 cars are trying new pieces to help with the heat. Those features are a shorter exhaust pipe and slits at the top of the rear window. Probst said officials would have a better idea of how that goes at the end of Monday’s test.

Probst also again shot down concerns over the safety of the Next Gen car. He is “very comfortable” with where the car stands, and there were no issues with the testing dummies.
