As a V8 Supercars driver, he raced 12 seasons in the series with a best finish of third at the 2003 Clipsal 500; he initially finished fourth, but a penalty for Russell Ingall promoted Weel onto the podium.[1] His best enduro finish was a 5th at the 2002 Queensland 500 and best Bathurst 1000 finish was 8th in 1999.
From 2006, he decided to retire from full-time driving to devote more time to his PWR Performance Products business.[2][3] On 10 October 2008, Weel was involved in a massive crash during a practice session at Bathurst;[4] his stopped car was hit by Chris Pither in the Reid Park sector, leading to back fractures, a split spleen, and punctured lung. In 2009, he participated in the Sepang 12 Hours and finished fifth overall.[5]
Weel returned to driving when he joined the Boost Mobile Super Trucks in 2020.[5] At Hidden Valley Raceway in June 2021, his truck flipped multiple times after making contact with Dave Casey on a ramp.[6] The following month at Reid Park Street Circuit saw him win the final two races for his first career overall weekend victory.[7]
In 2022, Weel and fellow Boost Mobile Super Trucks driver Toby Price formed Team Australia to compete in American desert racing.[8] news The team won for the first time at the SCORE International Baja 500 in 2024.[9]
