NASCAR is usually many years behind on the car technology; they do mention that in the article, the fuel injection, the fuel blend etc. and here they come out with "new digital dashboard system that is mandatory this season – teams can switch between as many as 16 preset screens to display information with three different graphic looks".
Can't wait to see it. Changing the screens will be one of the last things they worry about while racing; so it will be a set to the one they like the most, and leave it.
