SEMA Battle of the Builders Celebrates 10 Years of Competition

Celebrating its 10-year anniversary at the SEMA Show, the 2023 SEMA Battle of the Builders is proud to announce that Mothers Polish is returning as the competition’s presenting sponsor!

The SEMA Battle of the Builders (BOTB) Presented by Mothers Polish has been the aftermarket industry’s ultimate vehicle competition for 10 amazing years. Highlighting custom builders at the forefront of innovation, BOTB continues to champion the spirit of competition, the passion of the automotive aftermarket and the innovation of the builder community.

“For the last decade, SEMA’s Battle of the Builders has provided vehicle builders a special platform to showcase their imagination, ingenuity and craftsmanship while also fueling the love for competition and pride of accomplishment,” said RJ de Vera, SEMA vice president of marketing. “SEMA Show exhibitors are tremendously selective with the vehicles they choose to showcase their products, capture attention and drive traffic to their booths. BOTB not only offers an additional avenue for further exposure by featuring the top builders and brands that exhibit at the SEMA Show but also provides a chance for top builders from different genres to learn from each other building meaningful connections as they judge each other’s builds in the final round.”

The 2023 competition is revving up to be one of the most exciting competitions to date. Featuring more innovative builders that represent the best in the industry, it’s an event not to be missed.

“Battle of the Builders embraces everything that makes the automotive aftermarket great–the passion, drive, determination and creativity that defines our industry. And at Mothers, we’re truly grateful to be so closely connected with this distinguished competition,” said Mothers Polish CEO Dennis Holloway. 

Think you’ve got what it takes to compete with some of the best builders in the world? If you want to get in on the action, it’s not too late! Builders can still sign up to compete until Friday, October 13. Top builders will be recognized in four categories: Hot Rod & Hot Rod Truck; 4 Wheel Drive & Off-Road; Sport Compact, Import Performance, Luxury & Exotic; and Young Guns. An overall champion will be named on the final day of the SEMA Show from the four class winners.   

The competition will take place throughout the week of the Show, with the Top 40 announced on Tuesday, November 1, and the Top 12 celebrated on Wednesday, November 2. The decorated dozen will examine and critique each others’ vehicles at the Show on Thursday, November 3, as they become the final judges. Four class winners will be decided on Thursday as judging concludes, and the 2023 SEMA Battle of Builders overall champion will be announced on Friday, November 4.   

Throughout the competition, camera crews will follow the action for a television special that will air on The History Network, while daily behind-the-scenes videos will be posted on SEMA Show’s social profiles. For more information about the SEMA Battle of the Builders Presented by Mothers, visit
