what is the purpose of overdrive in a car
Overdrive (mechanics) Overdrive is a term used to describe the operation of an automobile cruising at sustained speed with reduced engine revolutions per minute (RPM), leading to better fuel consumption, lower noise, and lower wear.[1] Use of the term is confused, as it is applied to several different, but related, meanings.[1]
Formula One car Several teams started to experiment with the now familiar wings in the late 1960s. Race car wings operate on the same principle as aircraft wings, but are configured to cause a downward force rather than an upward one. A modern Formula One car is capable of developing 6 G's of lateral cornering force[15] (six times its own weight) thanks to aerodynamic downforce. The aerodynamic downforce allowing this, is typically greater than the weight of the car. That means that, theoretically, at high speeds they could drive on the upside down surface of a suitable structure; e.g. on the ceiling.
