Of course is quite unlikely that kind of engine could last 24 hours if set to revving up to >9000rpm all the time as they normally do.

Bristol ain't easy on the engines at all, the up and downs and high banking meant they were still torn down every weekend. With the last update I believe the engines are sealed and counted to start the season. Last I knew it was equal to 2 races per engine for the season so think that's 18 engines with an extra allowance for Daytona I believe. I have not seen Next Gen engine limits lately

I was thinking possibly a powertrain test for the new Vette hybrid system but Caddy plus spec hybrid option as well
