The Physics Trick That Makes These New Super Cars So Insanely Fast

With the additional downward drive, the one method for the forces so as to add as much as zero is that if the traditional drive will increase. This implies the frictional drive is larger, so the brand new acceleration is larger.

Now as a substitute of getting a most acceleration of 6 to 7 meters per second squared, it is attainable to get a lot greater values—perhaps 15 and even 20 m/s². The McMurtry Spéirling within the video went from 0 to 60 mph in … anticipate it … 1.4 seconds. Simply fascinated by that can pin your ears again.

The fan thought is not new. In 1978, the Brabham BT46B used it to win the Components 1 Swedish Grand Prix, nevertheless it was shortly banned. The concept of accelerating downward drive lives on, nonetheless. F1 automobiles immediately channel airflow via the physique in intelligent methods to attain a number of the similar “floor impact”—justified by saying their function is to chill the engine.

Whereas these airflow methods do assist cool the engine, everybody is aware of the true function is to generate low strain beneath the automobile to suction it nearer to the street. In truth, the brand new McLaren W1 that we recently reviewed is a street automobile that makes this the gross sales pitch. (You should buy one for $2.6 million—or you possibly can have for those who’d signed up in time. McLaren is making solely 399.)

The cool half is that this greater acceleration is not only for rising your pace. It additionally permits the automobile to decelerate quicker and even make sharper turns, since these are additionally sorts of acceleration. The downward thrust can flip a quick automobile right into a crazy-fast automobile—if that is what you need. For me, I am completely happy so long as it is a pink automobile and it drives.
