The time it takes a vehicle to accelerate from 0 to 60 miles per hour (97 km/h or 27 m/s), often said as just "zero to sixty" or "nought to sixty", 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.
Speed limit sign in the Republic of Ireland, using "km/h.". The SI representations, classified as symbols, are "km/h", "km h −1" and "km·h −1".Several other abbreviations of "kilometres per hour" have been used since the term was introduced and many are still in use today; for example, dictionaries list "kph", [3] [4] [5] "kmph" and "km/hr" [6] as English abbreviations.
By 0–60 mph (97 km/h) (less than 3.0 s) [ edit ] Many elements change how fast the car can accelerate to 60 mph. [ ii ] [ iii ] Tires, elevation above sea level, weight of the driver, testing equipment, weather conditions and surface of testing track all influence these times. [ 3 ]

The Stradale can generate a downforce of 400 kg (881 lb) at 241 km/h (150 mph) in its basic form and 853 kg (1,880 lb) with its optional rear wing. The car accelerates from 0–97 km/h (0–60 mph) in 3.2 seconds, 0–161 km/h (0–100 mph) in 8.1 seconds, can complete a quarter-mile in 11.4 seconds and can attain a top speed of 280 km/h (174 mph).
The BAR-Honda 007 set an unofficial speed record of 413 km/h (257 mph) at Bonneville Speedway. The 1.6 L V6 engine on a modern F1 car churn out 710 kW (950 bhp) at 15,000 rpm. [68] [69] This enables a modern F1 car to accelerate from 0 to 60 mph (0 to 97 km/h) in 1.8 seconds, and from 0 to 100 mph (0 to 161 km/h) in 2.6 seconds. [70]
A series of Locomotive Acts (in 1861, 1865 and 1878) created the first numeric speed limits for mechanically propelled vehicles in the UK; the 1861 Act introduced a UK speed limit of 10 mph (16 km/h) on open roads in town, which was reduced to 2 mph (3 km/h) in towns and 4 mph (6 km/h) in rural areas by the 1865 "Red Flag Act".
