Rally Racing Cars
The typical rally course is comprised of a sequence of relatively short, timed stages. This is where the actual competition takes place. In between these points, there are often untimed transport stages where the driver and navigator bring the car under its own power to the starting point of the next section.
This unusual requirement forced rally cars to be unlike any other top-of-the-line, professional racing car. The rally car must be able to perform at normal driving speeds, and the racing team must be able to register it for street use in the country where the course is located. In addition, the rally car must account for the weight of a second passenger, the navigator.
While forcing these features and characteristics onto a racecar may seem unusual to the uninitiated, it provides much of the allure for fans of the sport. Technology and mechanical ingenuity are still important components. However, this setup accentuates the skills of the driver and the navigator.
