The time it takes to accelerate from 0 to 60 mph (0 to 97 km/h or 0 to 27 m/s) is a commonly used performance measure for automotive acceleration in the United States and the United Kingdom. In the rest of the world, 0 to 100 km/h (0 to 62.1 mph) is used. Present performance cars are capable of going from 0 to 60 mph in under 5 seconds, while exotic cars can do 0 to 60 mph in between 2 and 3 seconds, whereas motorcycles have been able to achieve these figures with sub-500cc since the 1990s. The fastest automobile in 2015 was the Porsche 918 Spyder, which is a hybrid vehicle taking 2.2 seconds to accelerate from 0 to 60 mph.
