The overall performance of a modern Formula One car is truly astonishing. The acceleration time from zero to 60 mph is a ‘modest’ 2.4 seconds, but this is because the car cannot put enough power down through the tyres. In reality the car’s acceleration accelerates: the next 60 mph to 120 mph requires only an extra two seconds. And the braking is astonishing: from 200 mph to a standstill in 3.5 seconds. The forces experienced by the drivers are also impressive, 5g in braking and 4g in cornering. By comparison, a high-performance road car might achieve 1g braking and cornering. The excessive g-forces explain why the drivers have to be superb athletes, comparable with any Olympian.
The cars can generate downforce equivalent to their mass, ¾ of a tonne at 110 mph, which means theoretically that, at that speed, they could drive along upside down and stick to the ceiling. At top speed, the cars generate 2.5 tonnes of downforce. The drag is so high that just lifting off the throttle at maximum speed will give over 1g of deceleration –the same level as a performance road car braking hard. In other words, an F1 driver who lifts his foot off the throttle will decelerate as quickly as a Porsche 911 driver doing an emergency brake.
Started reading Total Competition by Ross Brawn and Adam Parr. Early on in the book he gives an explanation of why Formula One cars are so incredible; it’s not just outright speed, it’s also how quickly they accelerate, brake and the extreme downforce and drag the aerodynamics generate. Fascinating.
