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 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.

The kilometre, a unit of length, first appeared in English in 1810, [9] and the compound unit of speed "kilometers per hour" was in use in the US by 1866. [10] "Kilometres per hour" did not begin to be abbreviated in print until many years later, with several different abbreviations existing near-contemporaneously.
The speed limit is commonly set at or below the 85th percentile speed (the operating speed which no more than 15% of traffic exceeds), [55] [56] [57] and in the US is frequently set 4 to 8 mph (6 to 13 km/h) below that speed. [58]

The legislation required 55 mph (89 km/h) speed limits on all four-lane divided highways unless the road had a lower limit before November 1, 1973. In some cases, like the New York State Thruway, the 50 mph (80 km/h) speed limit had to be raised to comply with the law. The law capped speed limits at 55 mph (89 km/h) on all other roads. [18]
