That 53 feet 60-0 is a Ferrari race car, which has aerodynamics that sucks it down to the ground, more than 1g of additional downforce. Often referred to as "they could drive upside down to the roof of a tunnel.
Years ago in Denver when they had F1 racing, I remember a news story about preparations the city had to do for the race, which included welding down the manhole covers. Because the amount of suction these cars make would pull the manhole covers off as cars drove over them.
Also, traction is more than just friction. There's a mechanical component to it, the scraping off of the rubber from the surface of the tire.
Also, as far as the 53 feet goes, remember that this car was extremely light, 1400lbs. The Tesla Model S weighs almost 5Klbs for comparison.
- m463 6y agoI loved the story of the Chaparral 2J with "active downforce": https://en.wikipedia.org/wiki/Chaparral_Cars#2J https://en.wikipedia.org/wiki/Chaparral_Cars#2J Two fans adapted from a military tank engine were housed at the rear, driven by a single two-stroke twin-cylinder engine. ... The skirting produced a zone within which the fans could create a vacuum producing downforce on the order of 1.25 to 1.50 G when the car was fully loaded Maybe this sort of thing will make a comeback :) https://en.wikipedia.org/wiki/Cold_gas_thruster https://en.wikipedia.org/wiki/Cold_gas_thruster

That downforce drops to zero long before the car stops. >Also, as far as the 53 feet goes, remember that this car was extremely light, 1400lbs. The Tesla Model S weighs almost 5Klbs for comparison. It doesn't matter how much something weighs... the kinetic energy scales linearly with weight. The F-16 fighter can pull 9gs, and it weighs 20,300 lbs.

It's also possible that this stopping distance was measured with the aerodynamics tuned for 60-0 braking, because they adjust the aerodynamics all the time. >It doesn't matter how much something weighs Stopping distance is absolutely, 100%, impacted by the weight of the car.
