Gas-powered cars will soon be replaced by electric cars, which will be replaced by two-person motorcycles powered by nightmares. Catch some combustion-engine action while you can with today's Groupon: for $24, you get four tickets to a Friday-night stock car racing event at Belle-Clair Speedway (a $48 value), located in Belleville.

For 27 years, Belle-Clair Speedway has invited motorheads inside its dirt temple of speed to revel at car jockeys gently guiding their mud machines from point A to point A on a 1/5-mile, banked-oval dirt track. Belle-Clair Speedway showcases five classes of racecar, including UMP Super Late Models, Modifieds, Sportsman, Pure Stocks, Pro 4 Stocks, and rocket-powered soap-box derby cars driven by hamsters. The nightly events include qualifying heat races, dashes, semis, and feature events for each car type. Check the Belle-Clair website for each night's promotional activity, including Salute to the Military night on May 27 and the Three Dog Night '70s Dress-Up Contest on August 26.
