The British Touring Car Championship or BTCC is one of the most competitive and sensational tip top championship series in the world. Big manufacturers and privateer teams compete for race wins to be crowned British Touring Car Championship. Unlike other championship series, the competition is so close that it is not dominated by the big manufacturers, and the Independent teams regularly win races and are frequently in the running for both the drivers Championships and the constructor’s championships.
A lot of this close competition is because of the rules, the rules are pretty restrictive and even some of the parts like the gearbox and drive trains are standardised components. This is done to decrease the costs and to decreasecut development time of new vehicles. Ford managed to develop its Fiesta in Australia and in as little as 14 weeks due to the standardised components. Teams can choose their engine, which is has to be a 4 cylinder engine with a turbocharger with a maximum displacement of 2 Litres. This will develop around 300 hp and these engines have to be from a production engine and last the entire championship year without needing to be rebuilt. These engines can be fuelled by petrol, bio ethanol, LPG and diesel and to ensure that each fuel develop a similar amount of power the boost pressure turbo is altered. The teams can also design their own suspension, although a lot ofparts like this spring’s and dampers are available off the shelf. Also, to decrease costs, one maker of tyres is picked to make one tyre to use on all the race circuits; this has become known as the control tyre. The touring cars have to be based on a production vehicle and everything but the chassis is stripped out and racing seats installed. The roll cage must be strong enough to survive the biggest of impacts and they also have five point racing seatbelt and a racing fuel tanks to minimise the risk of fire. This is all done to make the touring cars as safe as possible, as impacts in this formula are common. Most of these impactsare small but every now and again there is a really big one.
We have heard that the racing is close in the British Touring Car Championship, and as a result even a tiny advantage can make a difference between finishing first and finishing at all. This is why if you want to be a champion, it is vital not to overlook the smallest detail on the vehicle, such as the wiper blades. But how can wiper blades make a difference to the performance of a race car? The obvious way is in a wet race where wiper blades are required to clear precipitation and muck from the windscreen. It is vital that replacement wiper blades are fitted to the cars frequently, as allowing the replacement wiper blades to degrade when they are not in use is dangerous. Their ability to clean the windscreen of precipitation and muck can also be affected by the design. The pinnacle of replacement wiper blade design is one with no metal frame and this is called a flat wiper blade. These flat wiper blades are sprung to give an even pressure along the blade guaranteeing a streak and jump free wipe. The advantages of flat wiper blades are they have no frames, so they can sit closer to the windscreen, which helps smooth the airflow over the car. This improve airflow can improve the top speed of the car, whilst increasing the down force generated by the rear wing by allowing the airflow to be less turbulent when it reaches it.
