Funny Car is a type of drag racing vehicle and a specific racing class in organized drag racing. Funny cars are characterized by having tilt-up fiberglass or carbon fiber automotive bodies over a custom-fabricated chassis, giving them an appearance vaguely approximating manufacturers' showroom models. They also have the engine placed in front of the driver, as opposed to dragsters, which place it behind the driver.

Funny car bodies typically reflect the models of newly available cars in the time period that the funny car was built. For example, in the 1970s, then current models such as the Chevrolet Vega or Plymouth Barracuda were often represented as funny cars, and the bodies represented the Big Three of General Motors, Ford, and Chrysler.[2] Currently, four manufacturers are represented in National Hot Rod Association (NHRA) Funny Car — Chevrolet with the Camaro,[3] Dodge with the Charger,[4] Ford with the Mustang,[5] and Toyota with the Camry.

Today, fielding a Funny Car team can cost between US$2.6 and US$3 million.[8] A single carbon fiber body can cost US$70,000.

The NHRA has strict guidelines for Funny Cars. Most of the rules relate to the engine. In short, the engines can only be V8s displacing no more than 500 cu in (8,193.53 cc). The most popular design is a Donovan, loosely based on the second generation Chrysler 426 Hemi.

There can only be two valves per cylinder. The heads are machined from aluminum billet and have no water jackets, as the high latent heat of the methanol in the fuel coupled with the brevity of the run precludes the need. Superchargers are restricted to a basic Roots type—19-inch (480 mm) rotor case width with a breadth of 11.25 in (286 mm). Only single camshafts are allowed. There are two common bore-stroke combinations: 4.1875 in × 4.50 in (106.36 mm × 114.30 mm) (called a 3/4 stroker) and 4.25 by 4.375 inches (108.0 mm × 111.1 mm) (called a 5/8 stroker). The 3/4 stroker is the most common combination used today and equals 496 CID (8.1 L).

Funny Car fuel systems are key to their immense power. During a single run (starting, burnout, backing up, staging, 1/4 mile) cars can burn as much as 15 US gallons (12 imp gal; 57 L) of fuel. The fuel mixture is usually 85–90% nitromethane (nitro, "fuel") and 10–15% methanol (alcohol, "alky"). The ratio of fuel to air can be as high as 1:1. Compression ratios vary from 6:1 to 7:1. The engines in Funny Cars commonly exhibit varying piston heights and ratios that are determined by the piston's proximity to the air intake. Funny Cars have a fixed gear ratio of 3.20:1 and have a reversing gear; power is transmitted from engine to final drive through a multiple staged clutch which provides progressive incremental lockup as the run proceeds. The rate/degree of lockup is mechanically/pneumatically controlled and preset before each run according to various conditions, in particular track surface. Wheelbases are between 100 and 125 in (2,500 and 3,200 mm). The car must maintain a 3 in (76 mm) ground clearance.

Horsepower claims vary widely—from 6,978 to 8,897—but are probably around 8,000 HP. Supercharged, nitromethane-fueled motors of this type also have a very high torque, which is estimated at 7,000 ft⋅lbf (9,500 N⋅m). They routinely achieve a 6G acceleration from a standing start.

The Chrysler Hemi engines, known by the trademark Hemi, are a series of American I6 and V8 gasoline engines built by Chrysler with hemispherical combustion chambers. Three different types of Hemi engines have been built by Chrysler for automobiles: the first (known as the Chrysler FirePower engine) from 1951 to 1958,[1] the second from 1964 to 1971, and the third beginning in 2003. Although Chrysler is most identified with the use of "Hemi" as a marketing term, many other auto manufacturers have incorporated similar designs.
