As a result, they do not have electric starters (or even electrical systems other than a ignition magneto) and require a push to be started. Sprint cars do not utilize a transmission but have an in-or-out gearbox and quick-change rear differentials for occasional gearing changes. A lower-budget and very popular class of sprint cars uses 360-cubic-inch (5.9L) engines that produce approximately 700 horsepower (520 kW). Depending on the mechanical setup (engine, gearing, shocks, etc.) and the track layout, these cars can achieve speeds in excess of 160 miles per hour (260 km/h). Typically, they are powered by a naturally aspirated, methanol-injected overhead valve V8 engine with a displacement of 410 cubic inches (6.7L) and capable of engine speeds approaching 9000 rpm. Sprint cars have very high power-to-weight ratios, with weights of approximately 1,400 pounds (640 kg) (including the driver) and power outputs of over 900 horsepower (670 kW), which give them a power-to-weight ratio besting that of contemporary F1 cars. Sprint car racing is popular primarily in the United States and Canada, as well as in Australia, New Zealand, and South Africa. Sprint cars are high-powered open-wheel race cars, designed primarily for the purpose of running on short oval or circular dirt or paved tracks.
