When you “redline” a car you’re revving the engine up to its maximum speed. This can damage the engine and cause it to overheat. Parts can break or wear out and you could end up stranded on the side of the road.
So why would anyone do this? In some cases it’s necessary. If you’re going to be drag racing or doing other high-performance driving you need to rev the engine up to its maximum speed to get the most power possible.
But even if you’re not planning on drag racing there are still times when you might need to redline your car. If you’re stuck in a snowbank and need to get moving quickly revving the engine up to its maximum speed can give you the power you need to get out.
Just be aware that redlining your car can be dangerous and should only be done when necessary. And if you do find yourself in a situation where you need to redline your car make sure you’re prepared for the consequences.
What is redlining?
Redlining is the illegal practice by financial institutions of denying services to or charging higher prices for services to customers in certain geographic areas because of the area’s racial or ethnic makeup.
