Top Fuel racing is a class of drag racing where cars are run on a mixture of up to 90% nitromethane and about 10% methanol rather than traditional gasoline. The cars are very long and narrow, with thin front tires that maximize performance in a straight line race. The National Hot Rod Association (NHRA) heavily restricts engine configuration, and as a result, today’s dragsters still use technology which is several decades old. Nonetheless, a Top Fuel dragster accelerates from 0 to 100 mph, or 160 km/h in less than one second. This is less than one tenth the time it takes a production model Porsche 911 Turbo to reach that speed!
