The main part of a racing car to which the engine and suspension are attached is called the chassis.
A tight sequence of corners in alternate directions. Usually inserted into a circuit to slow the cars, often just before what had been a high-speed corner.
Air that isn't turbulent, and thus offers optimum aerodynamic conditions, as experienced by a car at the head of the field.
The section of the chassis in which the driver sits.
Tread compound is the part of any tyre in contact with the road and therefore one of the major factors in deciding tyre performance. The ideal compound is one with maximum grip but which still maintains durability and heat resistance. A typical Formula One race compound will have more than ten ingredients such as rubbers, polymers, sulphur, carbon black, oil and other curatives. Each of these includes a vast number of derivatives any of which can be used to a greater or lesser degree. Very small changes to the mix can change compound performance.
