Overview

  • NASCAR's proposed 'Run What Ya Brung' format, allowing teams to build unrestricted setups, was rejected due to high costs and competitive imbalance.
  • Denny Hamlin estimated the format could cost teams up to $2 million per car, making it economically unfeasible even for well-funded organizations.
  • Smaller teams lacked resources like CNC machines, which would disproportionately benefit powerhouse operations such as Hendrick Motorsports and Team Penske.
  • Following the backlash, NASCAR abandoned the open-build concept and is now exploring limited rule changes, such as adjustable ride heights and spoilers.
  • Hamlin criticized the outdated $1 million All-Star Race prize and called for financially sustainable innovations to enhance fan excitement and competition.
