Car race

In single-seater (open-wheel) racing, the wheels are not covered, and the cars often have aerofoil wings front and rear to produce downforce and enhance adhesion to the track. The two most popular varieties of open-wheel road racing are Formula One and the IndyCar Series. In Europe and Asia, open-wheeled racing is commonly referred to as 'Formula', with appropriate hierarchical suffixes. In North America, the 'Formula' terminology is not followed (with the exception of F1). The sport is usually arranged to follow an international format (such as F1), a regional format (such as the Formula 3 Euro Series), and/or a domestic, or country-specific, format (such as the German Formula 3 championship, or the British Formula Ford). for more howtocottage.com
