The team was founded by Steve Dudman and entered the BTCC initially as a low-key operation, running under various titles and sponsorship arrangements over the years. Its base in Brackley, Northamptonshire, placed it in the heart of British motorsport geography. The outfit experienced financial difficulties at various points in its early history, which caused gaps in its competitive schedule, but Dudman maintained ownership continuity and repeatedly returned the team to the grid.
BTC Racing's first BTCC appearances came in 2006, when the team ran two Lexus IS 200 cars for Chris Stockton and Darren Dowling across the final two rounds of the season, treating the partial campaign as preparation for a fuller effort in 2007. For that following season, Stockton was retained alongside Nick Leason, though Leason only competed in the opening three rounds.
In 2008 the team switched machinery, initially continuing with the Lexus before replacing those cars with ex-Motorbase SEAT Toledos after two rounds. The season proved difficult; the team missed round six at Snetterton amid reported financial problems, and Gareth Howell made two appearances in place of Stuart Oliver. Plans to contest 2009 with SEAT Leóns were ultimately abandoned.
The team returned to the BTCC in 2014, fielding Chris Stockton in an NGTC-specification Chevrolet Cruze that had originally been built for the Silverline Chevrolet programme before that project was shelved. The car had been constructed by RML but never raced when that team opted not to contest 2012, making BTC's entry its competitive debut. In 2015, the team's Technical Business Licence was sold to title sponsor Automotive Brands, which established Power Maxed Racing as a separate two-car operation from that foundation.
After a further hiatus, the team announced in December 2016 that it would return to the grid for 2017 with Chris Smiley and Dave Newsham driving a pair of Chevrolet Cruzes purchased back from Power Maxed Racing.
For 2018, BTC Norlin — as the team was then known under its title sponsorship arrangement — switched to ex-Dynamics Honda Civic Type R FK2 cars as the works Honda operation moved to the new FK8 shape. The season proved to be the team's most competitive to that point. Daniel Lloyd took the team's first-ever BTCC race victory at Croft, and Chris Smiley followed with another win at Rockingham, making Smiley the last winner at the oval circuit before its removal from the calendar. At the close of 2018, Steve Dudman fully acquired the outfit, initially sharing the Team Principal role with Bert Taylor before taking sole control.
For 2019, now running as BTC Racing without the Norlin title sponsorship, Dudman fielded two Honda Civic Type R FK8 cars. Chris Smiley continued, joined by Josh Cook arriving from Power Maxed Racing. Cook proved immediately competitive, leading the championship standings after the opening Brands Hatch round, and the team finished the season fourth in the Teams' Championship, also claiming the Independents' runners-up award in both the Teams' and Drivers' standings.
The 2020 season saw BTC Racing expand to a three-car effort for the first time, retaining the Honda Civic Type R FK8 platform. Cook returned for a second campaign with the team, joined by Tom Chilton — a fourteen-times BTCC race winner and former WTCC and BTCC Independent champion who moved across from Motorbase Performance — and BTCC newcomer Michael Crees, who competed under The Clever Baggers with BTC Racing banner for the Jack Sears Trophy.
BTC Racing's trajectory reflects a pattern common to independent British touring car outfits: persistent financial pressures during the early years, careful machinery acquisition from departing works programmes, and eventual competitive consolidation once stable funding arrived. The team's Honda FK8 period marked its most sustained run of competitiveness, and the wins at Croft and Rockingham in 2018 represent landmarks in its history. The subsequent rebrand to One Motorsport continued the operation's presence in the BTCC under Dudman's ownership.
