🏳️ Mark DeBruler

Mark DeBruler is a developing amateur racer competing in NASA's Spec Miata class, a single-driver national series that fields production-based Mazda MX-5s in spec trim. He races for a large Mazda operation that has fielded over 1,200 drivers and won 1,257 races across the index. DeBruler is currently in his fourth season of indexed racing, with 24 starts across NASA from 2023 to the present.[1]

In the 2026 season, which is still in progress, DeBruler sits 82nd in the championship standings after ten rounds. His record across four seasons shows consistent participation in NASA's multiclass events, where Spec Miata competes alongside fourteen other classes on the same track. He has beaten competitive amateurs including Vaughn Mishko once and Lincoln Olson twice, though his results against regular opponents have typically placed him behind them; John Allen, a Bronze-graded competitive amateur, and fellow developing driver John Poppenhouse are among his most frequent competitors, and DeBruler usually finishes behind both.[2]
