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.
