In 2006, the International Motor Sports Association (IMSA) unveiled the Lites class for single-seat prototype race cars.
This series ran as a support event to the American Le Mans Series (ALMS).
It served as a training ground for drivers and teams that wanted to move up to the ALMS. It is now called the IMSA Prototype Challenge.
Initially, there were three categories (Lites 1, Lites 2 and Lites 3). The weight of these sports racers and engine type and displacement determined their classification. However, the series has evolved over time and underwent changes in 2019. The Mazda Prototype Challenge category, which has been part of the series since 2006, was dropped. Cars competing in this class are manufactured to Le Mans Prototype 3 specifications. The Le Mans Prototype 3 (LMP3) category was introduced in 2017. There are a number of race car manufacturers producing chassis' for this category: Ligier, Ave-Riley and Norma. They are equipped with Michelin tires and powered by a 5.0-liter naturally aspirated Nissan V8 motor, which produces 420-horsepower. All vehicles must weigh no less than 2,050-lbs. The 2019 season featured six race weekends, each contest one-hour, forty-five minutes in length. The exceptions were Daytona and Canadian Tire Motorsport Park, which were three-hour races.
Round four of the 2019 IMSA Prototype Challenge was held at Canadian Tire Motorsport Park. Drivers would compete in a three-hour contest around the ten turn 2.459-mile road course.
