With engines producing upwards of 800 horsepower, these 1200 pound rocket ships combine the thrill of raw power with the heart stopping action of non-wing sprint car racing. Dirt rooster tails, wheel stands and three wide racing are the norm when these bad boys come to town. Sprint cars also run on paved tracks and any driver with aspirations of a championship must be able to negotiate both dirt and pavement.

"I think the most challenging racing for a driver is Sprint Car racing on short dirt tracks. When you get a powerful sprinter on a short dirt course you’ve really got your hands full".
-- Two-time USAC National Sprint Car Champion, Parnelli Jones

"Sprint Car racing is one of the most exciting forms of racing to watch in the world".
-- Three-time Indianapolis 500 Champion Johnny Rutherford

Sprint cars are powered by 410 cu. in. V-8 engines with aluminum blocks and cylinder heads specially prepared for racing. USAC Western States sprint cars have a maximum of 360 cu. in. These engines use fuel injection and methanol for fuel. Sprint car races are normally held on 5/8 mile and smaller tracks; however, they sometimes make appearances at the 1-mile ovals. Some of the highlights on the USAC Sprint Car schedule are the "Little 500" at Anderson Speedway, the "Tony Hulman Classic" at Terre Haute, "USAC's Indiana Sprint Week", and the "4 Crown Nationals" at Eldora Speedway in Ohio.

A typical sprint car costs between $50,000 and $60,000 and most teams have a separate car for pavement and dirt tracks.

Previous champions of the USAC National Sprint Car Series are Ken Schrader, Tony Stewart, Rich Vogler, Johnny Rutherford and Parnelli Jones.

Midget racing dates back to the 1930's, and the basic concept has always been the same. Place the greatest amount of power on the smallest frame possible and put on an exciting show. The small size of these machines, combined with their power-to-weight ratio (2.5 pounds per horsepower), makes them perfect for oval tracks that are .5 mile and smaller in length. But, turn them loose on a larger track, and the speeds can reach over 150 mph, making them attractive for almost any racing facility of 1 mile or less.

USAC Midgets must weigh a minimum of 900 pounds without the driver and are limited to a wheelbase of 66 to 76 inches. Typically a midget engine can produce between 325 and 350 horsepower. For the mechanically minded, one of the highlights in USAC Midgets is the wide variety of engine designs. Power emanates from normally aspirated, internal combustion, four cycle, piston type engines with a maximum of six cylinders. All engines are fuel injected and burn straight methanol. From those basic guidelines, some of the most creative engine builders in racing have placed their mark on the sport.

Although the cars are small, the costs associated with midget racing are not. A basic car ready to race can cost between $40,000 and $60,000 without any extras.

USAC Midget racing has been a proving ground for some of the nation's great racing talent, due in part to the variety of tracks and the quick reflexes necessary for this type of racing. Former National Midget Series standouts Jeff Gordon, Tony Stewart, Billy Boat, Ryan Newman, Jason Leffler and John Andretti have turned a spotlight on the series as a source of racing talent. Other notable drivers who have made their way through the USAC Midget ranks include A. J. Foyt, Mario Andretti, Johnny Rutherford, Parnelli Jones and Mel Kenyon.
