The 2016 F1 cars have a power-to-weight ratio of 1,400 hp/t (1.05 kW/kg; 1,270 hp/U.S. ton; 0.635 hp/lb). Theoretically this would allow the car to reach in less than 1 second. However the massive power cannot be converted to motion at low speeds due to traction loss and the usual figure is 2.5 seconds to reach . After about traction loss is minimal due to the combined effect of the car moving faster and the downforce, hence continuing to accelerate the car at a very high rate. The figures are (for the 2016 Mercedes W07):
