Semi-feature

A semi-feature is a qualifying race in motorsports that gives drivers a final opportunity to earn a spot in the main event after failing to qualify through earlier rounds.

Think of the semi-feature as a "last chance race." In dirt track racing and other motorsport events, not every driver who shows up gets to compete in the main race, called the feature or A-main. Drivers first compete in heat races or time trials to earn their spots. Those who don't make it through these initial qualifying rounds get one more shot in the semi-feature.

The semi-feature, also called a B-main or last chance showdown, is typically shorter than the main event. Only the top finishers from this race transfer to the feature - usually anywhere from two to six drivers, depending on the event. The rest of the drivers are done racing for the night.

This qualifying race takes place after the heat races but before the main feature. It adds extra excitement to race night because drivers know it's their final opportunity to make the big show. The pressure is intense since there's no second chance after the semi-feature.

At large events with many cars, there might be multiple semi-features or even lower-tier races like C-mains and D-mains. Drivers can work their way up through these races, with winners advancing to the next level. Racing fans sometimes call this system "alphabet soup" because of all the different lettered races.

Drivers who transfer from the semi-feature to the main event typically start at the back of the field, behind those who qualified directly through heat races. This starting position reflects that the semi-feature is indeed a last-chance opportunity rather than a preferred qualifying method.

The semi-feature system ensures that skilled drivers who had bad luck or mechanical issues in their heat race still have a path to compete in the main event, making the overall racing program more competitive and entertaining.
