The championship was initially run with a mix of classes divided according to engine capacity, racing simultaneously. This structure allowed a driver who chose the right class to win the overall championship without achieving any overall race wins, thereby devaluing the title for spectators. In the 1980s, Chris Hodgetts won two overall titles in a small Toyota Corolla prepared by Hughes of Beaconsfield. While Ford Sierra Cosworth RS500s dominated at the front of the field, Frank Sytner took a title in a Class B BMW M3 and John Cleland won his first title in a small Class C Vauxhall Astra.
A street race around the city of Birmingham known as the Birmingham Superprix was held in 1989 and 1990.
In 1990, the BTCC introduced a class for cars with an engine displacement up to 2.0 litres, which was later adopted by the Fédération Internationale de l'Automobile and became the Super Touring regulations used in various championships across Europe and around the world. From 1991, these 2-litre cars became the only class eligible to compete. Six manufacturer-supported teams from BMW, Ford, Mitsubishi, Nissan, Toyota and Vauxhall entered in the first season.
Aerodynamic aids such as a front splitter or rear wing were permitted from 1995, following controversy when Alfa Romeo entered the 155 fitted with a rear wing in 1994. Audi joined the BTCC in 1996 with its four-wheel drive A4 Quattro and went on to take that year's title. The continuously high number of manufacturer-backed teams meant rapid development and quickly growing costs, which caused several manufacturers to withdraw until only Ford, Honda and Vauxhall remained in the 2000 season. The super touring era of the 1990s is considered the most successful period of the BTCC, characterised by close competition and large circuit attendance.
New regulations known as BTC Touring were introduced for the 2001 season to cut costs dramatically, though both manufacturer and spectator interest was low. The Super 2000 rules were adopted for the 2007 season. The 2000s saw cheaper cars than the Super Touring era, with fewer factory teams and fewer international drivers.
Vauxhall won four consecutive drivers and teams championships between 2001 and 2004. In 2005, Team Dynamics became the first independent outfit to win both the BTCC drivers and team championships; Matt Neal won the overall and independent drivers contests in his Team Dynamics Honda Integra, finishing all 30 championship races that year — a feat equalled only by Adam Morgan approximately ten years later in 2015. Team Dynamics and Neal were also victorious in 2006. Team Dynamics had previously achieved the first overall independents race win in the Super Touring era when Neal won a round of the 1999 BTCC at Donington Park, earning prize money of £250,000.
Vauxhall won the 2007 title with Italian Fabrizio Giovanardi. In 2010, following Vauxhall's withdrawal from the series, two new works teams entered: Chevrolet, run by RML, and Honda, run by Team Dynamics.
The BTCC released details of its Next Generation Touring Car (NGTC) specification in 2009, introduced from the 2011 season. These regulations were designed to dramatically reduce design, build and running costs, reduce reliance on WTCC/S2000 equipment, and minimise performance disparities between cars. A secondary Jack Sears Trophy class for S2000 machinery ran until the end of the 2014 season.
From 2014, only NGTC cars are eligible to compete in the BTCC. Cars are a mix of 2.0-litre saloons such as the BMW 3-Series and Infiniti Q50, and hatchbacks such as the Honda Civic, Toyota Corolla and Ford Focus. All cars share common components provided through a contract with RML Group, and teams may lease an engine built by Swindon Engines via TOCA. Goodyear Tire and Rubber Company is the current sole tyre supplier, providing Hard, Medium, Soft and Wet compounds.
Sustainable fuel was introduced full-time for the 2025 season; under NGTC regulations all entrants use Carless HiperFlo 300, a 101/102 RON unleaded gasoline meeting the FIA Appendix J specification.
Being a national championship, the BTCC has visited circuits throughout the United Kingdom over its long history. The current calendar of eight tracks across ten meetings comprises Brands Hatch (Indy Layout), Donington Park, Thruxton, Oulton Park, Croft, Snetterton, Knockhill, and Silverstone (National and International layouts), with a season-closing return to Brands Hatch (Grand Prix layout). Past venues include Mondello Park in Ireland, Pembrey in Wales, Aintree, Crystal Palace, Goodwood, Ingliston, Mallory Park and Rockingham.
The fastest track visited by the BTCC is Thruxton, where an average qualifying speed of 111.31 mph was set by Andrew Jordan in 2014.
Saturday of a race weekend comprises two practice sessions and a 30-minute qualifying session that sets the grid for the first race on Sunday. Each race typically consists of 16 to 25 laps depending on circuit length. The grid for Race 2 is based on the Race 1 finishing order. Race 3 features a reversed grid determined by a draw, with a position between sixth and twelfth from Race 2 taking pole position depending on which ball number is drawn. Points are awarded to the top fifteen drivers in each race, with one additional point for leading a lap.
Five championships are awarded per season: the overall drivers championship, the Independents drivers championship (awarded since 1992 to the leading non-manufacturer-backed driver), the best overall team, the leading manufacturer, and (since 2005) the top independent team. The Jack Sears Trophy, introduced for the 2013 season, has since 2015 been awarded to the highest-placed rookie driver at season's end.
The championship was screened in 1987 in the UK and some European countries by cable channel Screensport, and in Australia by the Seven Network produced by Hay Fisher Productions. The BBC screened highlights of every race from 1988 to 2001, with commentator Murray Walker; from 1997 some races were screened live with Charlie Cox joining Walker. ITV covered the series from 2002. Current coverage runs on ITV4 and ITVX. From 2025, worldwide broadcasting began with the BTCC YouTube Channel livestreaming to all countries except the UK and North America.
Each BTCC meeting is accompanied by the TOCA Support Package of single-make and formula championships. Current support series include the Porsche Carrera Cup GB, the Ginetta GT Supercup, the Ginetta Junior Championship, the Renault Clio Cup and the Mini Challenge. The F4 British Championship — formerly Formula Ford UK, rebranded as MSA Formula for 2015 and F4 British Championship from 2016 — uses a Mygale carbon-fibre monocoque chassis with a Ford 1.6L EcoBoost engine.
