# 2019 BUBBA Burger Sports Car Grand Prix

The 2019 BUBBA Burger Sports Car Grand Prix was a sports car race sanctioned by the International Motor Sports Association (IMSA). It was held at Long Beach street circuit in Long Beach, California on 13 April 2019. The race was the third round of the 2019 WeatherTech SportsCar Championship.

## Background

International Motor Sports Association's (IMSA) president Scott Atherton confirmed the race was part of the schedule for the 2019 IMSA SportsCar Championship (IMSA SCC) in August 2018. It was the sixth consecutive year it was part of the WeatherTech SportsCar Championship, and the thirteenth annual running of the race, counting the period between 2006 and 2013 when it was a round of the Rolex Sports Car Series and the American Le Mans Series respectively. The BUBBA Burger Sports Car Grand Prix was the third of twelve scheduled sports car endurance races of 2019 by IMSA, the shortest of the season in terms of distance, and it was the first round not held as part of the North American Endurance Cup. The race was held at the eleven-turn 1.968 mi (3.167 km) Long Beach street circuit in Long Beach, California on April 13, 2019.
On 4 April 2019, IMSA released a technical bulletin regarding the Balance of Performance for the race. In the Daytona Prototype International (DPi) class, the Acura ARX-05 was made 20 kilograms lighter, and received an increase in turbo boost, along with the Nissan DPi. The Mazda RT24-P was restricted in its boost, while being made five kilograms lighter. The Cadillac DPi-V.R, which won the previous two events of the 2019 season, was given a 10 kilogram increase. In GT Le Mans (GTLM), there were less significant changes. The Porsche 911 RSR was lightened by 10 kilograms, while the Ford GT had a slight reduction in boost.
Before the race, Jordan Taylor and Renger van der Zande led the DPi Drivers' Championship with 67 points, ahead of Pipo Derani, Felipe Nasr, and Eric Curran on countback followed by Hélio Castroneves, Ricky Taylor, and Alexander Rossi in third position with 58 points. With 63 points, Philipp Eng led the GTLM Drivers' Championship by 2 points ahead of Patrick Pilet, Nick Tandy, and Frédéric Makowiecki in second position followed by Connor De Phillippi and Colton Herta with 59 points in third position. Cadillac and Porsche were leading their respective Manufactures' Championships while Konica Minolta Cadillac and Porsche GT Team each led their own Teams' Championships.

### Entries

A total of 19 cars took part in the event split across two classes. There were 11 cars in the Daytona Prototype International class, and eight entries in GT Le Mans (GTLM). The Le Mans Prototype (LMP2) and GT Daytona (GTD) classes would not be participating in the event. There were few changes to the full-season lineups in either class. Kyle Kaiser, who joined the No. 50 Juncos Racing Cadillac DPi-V.R for the 24 Hours of Daytona, returned to the car alongside full-season driver Will Owen on a one-race deal. The Thursday before the race, it was announced one of Ford Chip Ganassi Racing's full-season drivers, Joey Hand, would be unable to compete due to suffering symptoms of the flu. His place would be taken by one of their endurance-event drivers, Sébastien Bourdais, who would also be competing in the IndyCar event.

## Qualifying

Friday's late afternoon qualification session into was broken two sessions that lasted 15 minutes each. Cars in GTLM were sent out first and, after a ten-minute interval, DPi vehicles drove onto the track. All cars were required to be driven by one participant and the starting order was determined by the competitor's fastest lap. IMSA then arranged the grid so that the DPi field started in front of all GTLM cars.
Hélio Castroneves in the No. 7 Acura set a new track record to clinch his first pole position of the season with a time of 1 minute and 11.332 seconds.

Following in third was the No. 6 Acura of Juan Pablo Montoya with the No. 5 Mustang Sampling Racing Cadillac of João Barbosa in fourth. Jonathan Bomarito's No. 55 Mazda set the fifth fastest time, but would start at the back of the DPi field after Mazda Team Joest rebuilt the car with a spare monocoque chassis as a result of Bomarito crashing at turn 6.
In GTLM, Nick Tandy clinched his first pole position of the season, with his fastest lap being 0.064 seconds faster than his teammate Laurens Vanthoor in the No. 912 Porsche. Following in third was Oliver Gavin's No. 4 Corvette with the No. 66 Ford GT of Sébastien Bourdais in fourth.
