There are two Classes in the SuperMini Challenge: Unlimited Class In the Unlimited SuperMini class you will find some incredible Minis, with both BMW Minis and Leyland Minis represented. These cars have few restrictions and owners and drivers are permitted to build and race at higher levels of modification and power and thus the cars can achieve some significantly lower lap times than the Cooper Class cars. These Minis are more likely Sport Sedans and Mini Challenge Cars running on slick tyres.
Are the Cars Reliable
The BMW Mini Cooper S has been in production since 2001, with many tens of thousands of vehicles produced all over the world. Due to the cult status the Mini enjoys, many aftermarket and tuning companies have developed the Mini over the last 20 years, and there are many performance and aftermarket tuning parts for Minis. Many roadgoing Mini Coopers are sporting more than 300HP as regular daily drivers, and some of the SuperMinis have significantly more power than that. Of course, as a race car, regular maintenance and attention to detail are crucial for reliability, however, the cars are a well-proven package when serviced and operated correctly.
