30 years on: when BTCC Super Tourers ruled the world

So a new set of rules were formulated; regulations that made sure all those taking part would be in with a shout of victory. On the surface, they were fairly simple. Initially, the new cars would have a naturally aspirated engine of 2.0 litres and not more than six cylinders, while a rev limit would be set at 8500rpm. There was to be no turbocharging, two-wheel-drive only (although this later changed temporarily to allow Audi to compete) and a minimum weight of 975kg. 

Cars built to the rules were first allowed to race in 1990, but it was the following year that all cars had to compete in this 2.0-litre formula. Quickly adopting the name Super Tourers, these tin-top racers proved to be a smash hit. Not only was the racing close and the TV coverage unrivalled, but they also looked like the cars that you or I might buy. It didn’t take long for the manufacturers to sit up and take notice.

When the factory-backed Schnitzer BMW squad arrived in 1993, it was clear the series was being taken seriously, while entries from Ford, Peugeot, Renault and Nissan further bolstered the championship’s credibility. But it was in 1994 that the Super Touring legend really took hold. This was the year the factory Alfa Romeo squad rolled into the paddock. 

Not only did the Italian outfit boast the driving services of ex-F1 ace Gabriele Tarquini, but it also introduced the rather naive world of the BTCC to aerodynamics. Using a homologation loophole, Alfa realised that you could build 2500 examples of a car that featured special modifications, in this case adjustable front and rear spoilers. 

The all-red 155s were quick out of the box, winning races at will, with Tarquini victorious in the first five races on the bounce as he and Alfa romped to the drivers’ and manufacturers’ championships. 

Yet rivals were up in arms and there followed numerous protests, with Alfa even boycotting the Oulton Park round in response to being told it couldn’t run with the wings. The only way to level the playing field was to allow other teams to run simple aero packages that didn’t require expensive homologation, and from this moment on, the BTCC and Super Touring entered a high-stakes, high-cost, high-technology race. 

It was ironic, therefore, that Tarquini later revealed the extra wings and splitters had little real effect, a view that was backed up by Cleland, who ran an aero-equipped Cavalier to his second title in 1995: “Compared to the 1996 Vectra, which had more carbonfibre than a moon rocket, all sorts of sensors and real aero, the Cavalier was a simple car. We effectively ran the same aero set-up wet or dry. In fact, we could shift the aero balance more by experimenting with how much to open the rear windows.”

Yet the simplicity wasn’t to last. Such was the growing importance of the BTCC that deep-pocketed manufacturers turned to motorsport royalty in an effort to win. Volvo teamed up with TWR, Ray Mallock ran the Vauxhalls and then the Nissans, while Renault contracted out its Lagunas to Williams F1 (it’s no surprise that, with 25 wins, the big French hatch became the BTCC's most successful Super Tourer). Then Audi arrived with four-wheel drive and cleaned up in 1996, before protests from other teams led to the reinstatement of the ban on total traction just two years after it was lifted.

With these top teams came the cream of international driving talent, who went head to head with home-grown heroes. Names like Alain Menu, Frank Biela, Laurent Aiello, Rickard Rydell took on Jason Plato, Steve Soper and Tim Harvey. 

The rivalries were legendary, with the 1992 needle match between Cleland and Soper proving particularly crowd pleasing (the Silverstone finale, with its on-board footage of Cleland’s one-fingered salute to his BMW rival, brilliantly covered by Murray Walker’s ‘I’m going for number one’ commentary, sums it up best), even if the reality was rather different. “I knew Steve from before the BTCC, even shared a car with him, and I’ve always had huge admiration and respect for what he’s achieved.”
