Energetic (and somewhat masked) crowds roared as car and truck races kicked into high gear on day two of the Acura Grand Prix of Long Beach. Unlike Friday, which was almost exclusively practice and qualifying laps, five competitions ran Saturday.

The races featured cars driving at break-neck speeds or drifting along the streets of Downtown, and trucks flying through the air on another perfect Southern California afternoon with sunny skies and temperatures in the mid to high 70s.

Stadium Super Trucks, a truck race that incorporates ramps for the trucks to launch themselves off of, was up first for the day. Driver Jerrett Brooks claimed the win, with Matt Brabham and Robert Stout taking second and third, respectively. A second race is slated for Sunday at 3:30 p.m. Former IndyCar and NASCAR driver Robby Gordon created the high-flying series in 2013.

Next up, Global Time Attack drivers made their Long Beach Grand Prix debut. The drivers speed highly modified street cars around the track one at a time in a race against the clock; the driver with the fastest single lap at the end of the weekend wins. A second heat is scheduled for Sunday at 10:10 a.m.

During a qualifying race, IndyCar driver Josef Newgarden won pole, which means he will start in first position in Sunday’s 46th annual Long Beach Grand Prix.

Sports cars flew around the circuit for 100 minutes during the IMSA SportsCar Grand Prix of Long Beach. The racing series, under sponsorship of WeatherTech, is based in the U.S. and Canada, the result of a merger between the Grand-Am Road Racing Sports Association and the International Motor Sports Association in 2013.

Historic Formula Atlantic cars, an open-wheel racer developed in the 1970s, took to the track next for the first of two 20-minute races this weekend. Formula Atlantic was used for professional racing  through the IMSA Atlantic Championship until 2009. Today, the cars primarily are used in amateur racing. The second race is scheduled for Sunday at 10:45 a.m.

Screeching tires and clouds of smoke closed out the day as Formula Drift drivers slid around Downtown for their final race weekend bout. Justin Pawlak came out victorious, with Trenton Beechum and Forrest Wang coming in second and third, respectively.

The technique of car drifting can be traced back to 1970s Japan and foremost creator Kunimitsu Takahashi. One of the first drifting races outside of Japan was in 1996 at Willow Springs Raceway in California, which helped create a buzz in the states. The 2006 film “The Fast and the Furious: Tokyo Drift” also did not hurt the sports popularity.

Race events resume Sunday morning, with gates opening at 7:30 a.m. The main event of the weekend, the NTT IndyCar series championship is set to begin at 12:45 p.m.
