Top Fuel is a type of drag racing whose dragsters are the quickest accelerating racing cars in the world and the fastest sanctioned category of drag racing, with the fastest competitors reaching speeds of 343.16 miles per hour (552.3 km/h) and finishing the 1,000 foot (304.8 m) runs in 3.641 seconds.
A top fuel dragster accelerates from a standstill to 100 mph (160.9 km/h) in as little as 0.8 seconds (less than one third the time required by a production Porsche 911 Turbo to reach 60 mph (96.6 km/h)) and can exceed 297 mph (478.0 km/h) in just 660 feet (201.2 m). This subjects the driver to an average acceleration of about 4.0 g0 (39 m/s) over the duration of the race and with a peak of over 5.6 g0 (55 m/s).
