Sprint cars are high-powered race vehicles that are built to compete on short oval or circular dirt or asphalt courses. Sprint car racing is popular in the United StatesCanadaAustraliaNew Zealand, and South Africa, among other places.

With weights of over 1,400 pounds (640 kg) (including the driver) and power outputs of over 900 horsepower (670 kW), sprint cars have a power-to-weight ratio that exceeds that of modern F1 vehicles. They’re usually driven by a naturally aspirated, methanol-injected overhead valve V8 engine with a displacement of 410 cubic inches (6.7L) and a top speed of 9000 rpm.

These cars may reach speeds of over 160 miles per hour (260 km/h) depending on the technical configuration (engine, gearing, shocks, etc.) and track layout. Sprint cars with 360-cubic-inch (5.9L) engines that produce around 700 horsepower are close to zero and extremely popular class (520 kW).

Sprint cars don’t have a transmission, instead of relying on an in-and-out gearbox and quick-change rear differentials for gear changes. As a result, they lack electric starters (or any electrical equipment other than an ignition magneto) and must be started by hand. The introduction of roll cages and, especially on dirt tracks, wings, which increase surface traction, to shield the drivers has considerably improved sprint car racing’s safety record in recent years.

Traditional sprint cars are wingless sprint vehicles that date back to the earliest sprint cars in the 1930s and 1940s (that ultimately evolved into Indy cars). They’re virtually the same car as a winged sprint car today; only they don’t have wings. Many of them, in fact, include “stub outs” in the frame that may be used to create wings. They typically utilize the same 410 cubic inches (6,700 cc) and 360 cubic inches (5,900 cc) aluminum engines as their winged counterparts (while many local tracks have regulations requiring steel blocks and certain 305 cubic inches (5,000 cc) displacements, this is primarily a cost restriction).

They typically utilize the same 410 cubic inches (6,700 cc) and 360 cubic inch (5,900 cc) aluminum engines as their winged counterparts (while many local tracks have regulations requiring steel blocks and certain 305 cubic inches (5,000 cc) displacements, this is primarily a cost restriction). Some of the newer regional groupings, such as POWRi and Elite, have decided to accept open engines with no size restrictions. For the performance at lower RPMs, they have a different tune and gearing than winged vehicles. Different chassis setups and tires are also available.

Although they may not have the same peak speed as a winged car (due to the absence of downforce for traction), many people believe they are more fun to watch. They have distinct driving characteristics than their winged counterparts due to their lack of grip, making them more difficult to steer around turns. Because of this, as well as the lack of roll-over protection provided by a wing, they are more hazardous than winged automobiles, and their crashes are noted for being spectacular.
