British Touring Car Championship

The British Touring Car Championship, officially known as the Kwik Fit British Touring Car Championship for sponsorship reasons, is a touring car racing series held each year in the United Kingdom, currently organised and administered by TOCA. It was established in 1958 as the British Saloon Car Championship and was renamed as the British Touring Car Championship for the 1987 season. It is one of the oldest, most popular and most prestigious touring car series in the world. The championship, currently running Next Generation Touring Car regulations, has been run to various national and international regulations over the years including FIA Group 2, FIA Group 5, FIA Group 1, FIA Group A, FIA Super Touring and FIA Super 2000. A lower-key Group N class for production cars ran from 2000 until 2003.

History

Early years

The championship was initially run with a mix of classes, divided according to engine capacity, racing simultaneously. This often meant that a driver who chose the right class could win the overall championship without any chance of overall race wins, thereby devaluing the title for the spectators – for example, in the 1980s Chris Hodgetts won two overall titles in a small Toyota Corolla prepared by Hughes of Beaconsfield, at that time a Mercedes-Benz/Toyota main dealer when most of the race wins were going to much larger cars; and while the Ford Sierra Cosworth RS500s were dominating at the front of the field, Frank Sytner took a title in a Class B BMW M3 and John Cleland's first title was won in a small Class C Vauxhall Astra.

Modern era

Super Touring cars

In 1990, the BTCC introduced a class for cars with an engine displacement up to 2.0 litres which would later be adopted by the Fédération Internationale de l'Automobile and become the Super Touring regulations that were used in various championships in Europe and around the world. In their first year, these cars were run alongside a second class which continued to allow larger engines and was once again dominated by the Ford Sierra Cosworth RS500, however from 1991 they became the only cars eligible to compete. The new one-class system was popular with manufacturers from the beginning with six manufacturer supported teams from BMW, Ford, Mitsubishi, Nissan, Toyota and Vauxhall entered in the championship. During the first seasons, the cars were not fitted with aerodynamic aids such as a front splitter or a rear wing which were allowed from 1995 after Alfa Romeo caused controversy a year earlier, when they entered the 155 fitted with a rear wing – an item that was delivered with the road-going version of the 155, however unfitted in its boot. 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 on the cars and quickly growing costs to compete which caused several manufacturers to withdraw from the championship until the 2000 season, when only Ford, Honda and Vauxhall remained in the championship. To this day, the 'super touring era' during the 1990s is still looked at as the most successful period of the BTCC. The high number of manufacturer-backed teams provided very close competition, close and hard-fought racing on track and many spectators at the circuits.

BTC Touring and Super 2000 cars

In order to reduce the costs to compete in the championship, the organisers introduced new regulations for the 2001 season. The BTC Touring regulations cut costs dramatically but both manufacturer and spectator interest was low. The Super 2000 rules were adopted for the 2007 season. The 2000s saw cheaper cars than the later Supertouring era, with fewer factory teams and fewer international drivers.

Next Generation Touring Car

In 2009, the BTCC released details of its Next Generation Touring Car specification, to be introduced from 2011. The introduction of these new technical regulations were designed to dramatically reduce the design, build and running costs of the cars and engines as well as reducing the potential for significant performance disparities between cars. The NGTC specification also aimed to cut costs by reducing reliance on WTCC/S2000 equipment, due to increasing costs/complexity and concerns as to its future sustainability and direction.

Current NGTC cars

Currently, the cars used are a mix of 2.0L saloons such as the BMW 3-Series and Infiniti Q50, and hatchback cars such as the Honda Civic, Toyota Corolla and Ford Focus, based on models from a variety of manufacturers, using NGTC regulations. S2000 cars continued running in the Jack Sears Trophy until the 2014 season.

Teams

BTCC teams are a mixture of manufacturer entries and independent teams such as BTC Racing, and Motorbase Performance.
In 2010, following Vauxhall's decision to pull out of the series, there were two new works teams Chevrolet, run by RML; and Honda, run by Team Dynamics.
In 2005, Team Dynamics became the first independent outfit to win the BTCC drivers and team championships; Matt Neal won the overall and independent drivers contests in his Team Dynamics Honda Integra. This included finishing all 30 championship races that year, something no other driver had achieved before and only equalled by Adam Morgan some 10 years later in 2015. This ended Vauxhall's run of 4 victories in the drivers and teams championships between 2001 and 2004. Neal and Dynamics were also victorious in 2006, before Vauxhall won the 2007 title with Italian Fabrizio Giovanardi. Team Dynamics also achieved the first overall independents race win in the 'Supertouring' era when Neal won a round of the 1999 BTCC at Donington Park, earning the team prize-money of £250,000.
As a result of Matt Neal's championship victories, and the fact that Team Dynamics were designing and building their own S2000 Honda Civic Type R, they were no longer entered into the Independents category, and were classed as neither an "independent" or "works" team until the 2009 season, when the Manufacturers championship was renamed Manufacturers/Constructors Championship to allow both Team Aon and Team Dynamics to compete with at the time the sole works entry of Vauxhall.

Car regulations

Current regulations

As of the 2014 British Touring Car Championship, all cars are built to the same regulations:

Next Generation Touring Car. New set of regulations specifically developed for the BTCC as a way of moving the sport forward and cut costs for competitors. Introduced from 2011, these new technical regulations were designed to dramatically reduce the design, build and running costs of the cars and engines as well as reduce reliance on WTCC/S2000 equipment. NGTC cars initially maintained performance parity with S2000 cars until the 2013 season when full NGTC cars became the main championship class with Hybrid S2000/NGTC cars running in a secondary class. From the 2014 season, only NGTC cars are eligible to compete in the BTCC.
Cost control measures

There are strict limits to the modifications which can be made to the cars, which are intended to reduce the cost of running a competitive team, which had become prohibitive in the final years of the Super Touring rules. These cost reductions saw a rise in independent entries – teams or individuals entering cars purchased from the manufacturer teams when they update their chassis.
With the introduction of the NGTC rules, all cars share a number of common components provided through a contract with RML Group. This has allowed many independent teams to enter without the need for manufacturer support, and negating the need to source ex-works cars.
Teams can install an engine from their marque's broad 'family' of cars, or opt to lease an engine from TOCA, built by Swindon Engines which also helps to make the cost of entry more affordable.
To further keep costs in check, the BTCC uses a single tyre supplier, with Goodyear Tire and Rubber Company the current supplier of rubber to all the teams. The following compounds are used: Hard, Medium, Soft and Wet.

Fuels

The rules previously allowed for a variety of different fuels in a bid to encourage more efficient cars. In 2004 Mardi Gras Motorsport independently entered a Liquified petroleum gas powered Super 2000 Honda Civic Type-R, and in 2005 Tech-Speed Motorsport converted an ex-works Vauxhall Astra Coupé to run on bio-ethanol fuel. In the middle of 2006, Kartworld's owner-driver Jason Hughes converted his 4-cylinder MG ZS to run on Bio-Ethanol, soon followed by the West Surrey Racing cars of championship contender Colin Turkington and Rob Collard, and for the final event at Silverstone, Richard Marsh converted his Peugeot 307 to run on bio-ethanol fuel. Only Hughes continued on this fuel in 2007 and 2008.
The regulations also permitted cars to run on diesel; attempted first in the 2007 season by Rick Kerry in a BMW 120d E87 run by Team AFM Racing. In 2008 SEAT Sport UK entered two Turbo Diesel Power SEAT Leons – the first diesel powered manufacturer entered cars.
At the start of the 2010 season, it was announced that Team Aon Racing had converted both of their Ford Focus ST cars to run on LPG. In 2024, Daryl DeLeon ran his Cupra Leon on 100% sustainable fuel for the final two meetings. Such fuels were introduced full-time for the 2025 Season.
Under current NGTC regulations, all entrants use Carless HiperFlo 300 which is a 101/102 RON and 89/90 MON unleaded gasoline with approximately 2% oxygen content that meets the FIA 'Appendix J' gasoline specification.

Previous regulations

The following regulations have been applied to the championship:

1958 – unique BTCC regulations
1959 – FIA Appendix J Category C
1960 – 'silhouette' special saloon cars
1961 to 1965 – FIA Group 2
1966 to 1969 – FIA Group 5
1970 to 1973 – FIA Group 2
1974 to 1983 – FIA Group 1
1983 to 1990 – FIA Group A
1991 to 2000 – 2 Litre Touring Car Formula, later becoming FIA Super Touring
2001 to 2011 – BTC Touring. The BTCC developed and introduced this specification in 2001, in response to the spiralling costs of the Super Touring specification. However, with the Super 2000 specification being used in the newly reformed World Touring Car Championship, the popularity of the BTC-T spec with top teams and manufactures was short lived. Therefore, from the 2007 season, BTC-T spec cars were no longer allowed to win the championship outright. The 2010 season was meant to be the last year BTC-T cars would be eligible to enter the championship, however Series Director Alan Gow announced a one-year extension to allow BTC-T to compete in 2011. Only cars that competed in 2010 would be eligible to race in 2011.
2004 to 2013 – Super 2000. Regulations first introduced to the BTCC in 2004, allowing teams to build cars eligible to race in several different Touring Car Championships, including the World Touring Car Championship. Car built to this specification were eligible to compete until the end of the 2013 season, however the last fully S2000 cars were entered in the 2011 season.
2010 to 2013 – S2000/NGTC Hybrid. From the 2010 season, teams with S2000 chassis were allowed to use an NGTC engine with their car. As of the 2012 season, all teams with S2000 chassis, used NGTC turbo charged engines. This hybrid specification was eligible until the end of the 2013 season.
