Straight

A straight is a section of a racetrack that runs in a straight line or with only a very gentle curve, allowing drivers to reach their highest speeds without needing to brake or turn sharply.

Straights are the fastest parts of any racing circuit. Unlike corners where drivers must slow down and carefully steer their cars, straights let drivers keep their foot pressed hard on the accelerator. This is where you'll see race cars hitting their top speeds, sometimes exceeding 200 miles per hour in professional series like Formula 1 or IndyCar.

Every racetrack is made up of a combination of straights and corners. The straights connect the turning sections together, creating the complete track layout. The most important straight on any circuit is called the "home straight" or "main straight," which is where the start/finish line is located. Many tracks also have a "back straight" on the opposite side of the circuit.

The length of straights varies dramatically between different racetracks. Some circuits feature short straights of just a few hundred meters, while others have extremely long ones. The famous Mulsanne Straight at the Le Mans circuit in France was historically over 6 kilometers long before chicanes were added for safety reasons. Longer straights generally mean higher top speeds.

Straights are critical for overtaking opportunities in racing. When following another car, drivers can use a technique called "slipstreaming" or "drafting." This means tucking in behind the car ahead to reduce wind resistance, which allows them to gain extra speed and attempt to pass. Without straights, overtaking would be much more difficult and dangerous.

Car setup plays an important role on straights. Racing teams must find the right balance between having enough downforce (the aerodynamic force that pushes the car down onto the track) for good cornering performance and minimizing drag (air resistance) for maximum straight-line speed. Cars set up for tight, twisty tracks will be slower on straights than cars optimized for circuits with long straights.

Smart racers know that straight-line speed isn't just about what happens on the straight itself. The key is getting a good "exit" from the corner before the straight. By accelerating as early and smoothly as possible when coming out of a turn, drivers carry more speed onto the straight, giving them an advantage over competitors who exit the corner more slowly.
