NHRA Top Fuel dragsters are the world’s fastest accelerating land vehicles. They can go from 0 to 60 mph in half a second. The lightweight drag rails can travel a quarter-mile in 4.4 seconds while achieving speeds of more than 335 mph. They are the most famous and recognizable class of drag racing cars, known around the globe. The engines operate under such stressful conditions they must be torn down and rebuilt between every run.
