One of the big events that takes place annually during Charlotte race weeks is the Randy Dorton Hendrick Engine Builder Showdown, which takes place on the Hendrick Motorsports campus near Charlotte Motor Speedway.
This event pairs the top 12 Hendrick Certified Master Technicians from the Hendrick Automotive Group with 12 Hendrick Motorsports engine department team members. Each team builds a race engine similar to those used in the Monster Energy NASCAR Cup Series.
A random draw determines the teams. The event offers two rounds of competition over two days, where each team has a qualifying build and two teams moving to the final.
