Power Maxed Racing first joined Britain’s premier motorsport series in 2014, with former sportscar racer Chris Stockton taking to the wheel of a Chevrolet Cruze before the squad expanded to a two-car operation for Renault UK Clio Cup runner-up Josh Cook and BTCC race-winner Dave Newsham the following year. The team achieved a podium finish at Rockingham and consistently challenged inside the top ten. 

Ahead of 2017, PMR announced that Vauxhall would be returning to the fray as a Manufacturer, with its new Astra replacing the team’s Chevrolet. Tom Chilton joined the factory effort and scooped silverware on the opening weekend, whilst team-mate Senna Proctor was crowned champion in the ultra-competitive Jack Sears Trophy at the end of an impressive rookie season. 

Proctor took a first BTCC race win at Brands Hatch in 2018, winding up a creditable 12th in the overall classification, as new team-mate Josh Cook picked up a brace of victories and four further podium finishes on his way to sixth in the standings. Power Maxed TAG Racing concluded the campaign a best-yet third in the Teams’ table – tied on points with second-placed Halfords Yuasa Racing. 

In 2019, Jason Plato returned to Vauxhall machinery and was joined by Rob Collard in an all-new driver line-up for Sterling Insurance with Power Maxed Racing. The pair powered their way to fifth in the Teams’ Championship, with Plato winning the final race of the season. 

Adrian Flux with Power Maxed Racing made its BTCC return with stalwart Jason Plato partnered by series returnee Dan Lloyd in 2021, with Plato celebrating his 600th BTCC race start with the squad. 

In 2023, CarStore Power Maxed Racing produced a new line-up, including race-winner Aron Taylor-Smith and rookies Mikey Doble and Andrew Watson. It was a great year for the team as Taylor-Smith made a welcome return to the podium, whilst Doble and Watson duelled it out for the Jack Sears Trophy. 

Taylor-Smith and Doble remained with the team for a dominant 2024. The former taking the Independent Drivers’ Crown and the latter taking the Jack Sears Trophy title, combining to take the Independent Teams’ Championship as well.

The following year saw Doble return to fly the flag for Motor Parts Direct with Power Maxed Racing at the opening event, swiftly joined by Nick Halstead for the remainder of the year. After an unfortunate factory fire saw the end of the Vauxhall Astras before Knockhill, the team competed in Cupra Leons to finish out the year.

In 2026, the team brings the all-new Audi A3 Saloon to the grid, with Dexter Patterson coming into the fold, competing for the newly named Steel Seal with Power Maxed Racing, as the stable grows back to a three-car entry under two team names.
