A gasser's goal was to be the quickest car in the class that didn't get DQ'd. For a few years, the popular configuration was to elevate them for weight transmission. They then returned to earth. Many gassers won using standard A-arm front suspensions. Some even had independent rear ends. The name comes from the fact that these cars were originally built with two-stroke engines, but many were also converted to four-strokes later on. They are best known for their use in the Indianapolis 500 race, but they also competed in various other events throughout the world. Generally, only open wheel/stock car classes would accept gassers as starters due to their larger size compared to most other classes at the time. In addition to being fast, gassers were also reliable and easy to maintain. The two-stroke engine made them environmentally friendly too! There have been gassers in several forms over the years. Today, they are mostly remembered for their use during the early 1950s. However, some modern racers such as the GRC Toyota GR4 continue to take part in events where gassers used to reign supreme. Interest in gassers has increased in recent years due to their appearance in several films including "March or April" by Walt Disney Productions in 1952.
