The 2019 Northeast Grand Prix was a sports car race sanctioned by the International Motor Sports Association (IMSA). The race was held at Lime Rock Park in Lakeville, Connecticut, on July 20, 2019, as the eighth round of the 2019 WeatherTech SportsCar Championship, and the fourth round of the 2019 WeatherTech Sprint Cup.

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 fifth consecutive year the event was held as part of the WeatherTech SportsCar Championship and the twenty-seventh annual running of the race. The 2019 Northeast Grand Prix was the eighth of twelve sports car races of 2019 by IMSA, and it was the fourth of seven rounds held as part of the WeatherTech Sprint Cup. The race was held at the seven-turn Lime Rock Park in Lakeville, Connecticut on July 20, 2019. The race was the first of two GT-only rounds on the 2019 IMSA calendar in which the prototype classes, Daytona Prototype international (DPi) and Le Mans Prototype (LMP2) would not take part.

On July 11, 2019, IMSA released a technical bulletin regarding the Balance of Performance for the race. The GT Le Mans (GTLM) balance of performance constraints would remain as they were in the previous round at Canadian Tire Motorsport Park. In the GT Daytona (GTD) class, after winning the previous round, the BMW M6 GT3 was given a power reduction of 12 horsepower, as well as a 2-liter fuel capacity reduction and a restriction of turbo boost. The Ferrari 488 GT3 and the Porsche 911 GT3 R were made 10 and five kilograms lighter, respectively.

Before the race, Earl Bamber and Laurens Vanthoor led the GTLM Drivers' Championship with 186 points, ahead of Patrick Pilet and Nick Tandy in second. In GTD, Mario Farnbacher and Trent Hindman led the Drivers' Championship with 151 points; the duo held a nineteen-point advantage over Frankie Montecalvo and Townsend Bell in second followed by Bill Auberlen and Robby Foley with 123 points in third. Porsche and Acura were leading their respective Manufacturers' Championships, while Porsche GT Team and Meyer Shank Racing each led their own Teams' Championships.

Entries

A total 21 cars took part in the event split across two classes. There were eight cars entered in GTLM, and 13 in GTD. The most notable change to the grid included the return of Blancpain GT World Challenge America full-time team Wright Motorsports, with drivers Anthony Imperato and Porsche Junior Professional driver Matt Campbell. Pfaff Motorsports regular driver Scott Hargrove would sit out the Lime Rock Park event as well as the following event at Road America, replaced instead by Porsche Junior driver Dennis Olsen for the Lime Rock event. Olsen and Campbell would switch places for Road America. Due to this event happening 50 years and one day after the Apollo 11 Moon landing, GTD team Magnus Racing decided to commemorate the anniversary of the mission by launching a one-off livery designed to look like the Saturn V rocket, and run under the number 11. As Magnus Racing usually ran under car number 44, the team received special dispensation by IMSA to count the points they would score as number 11 towards their full-season points under number 44.

Qualifying

Saturday's morning qualifying session was divided into two groups that lasted 15 minutes each. Cars in GTD were sent out first and, after a ten-minute interval, GTLM 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 GTLM field started in front of all GTD cars.

The first was for cars in the GTD class. Trent Hindman qualified on pole for the class driving the No. 86 car for Meyer Shank Racing, beating Ben Keating in the No. 33 Mercedes-AMG by less than one-tenth of a second. The No. 48 Paul Miller Racing Lamborghini Huracán of Corey Lewis set the third fastest time. However, the team were sent to the back of the GTD grid after the car failed post-qualifying technical inspection where it was discovered that the Lamborghini was found to not have complied with mandated ride height. As a result, Robby Foleys No. 96 Turner Motorsport BMW was promoted to third position followed by Zacharie Robichon's No. 9 Pfaff Motorsports Porsche in fourth, and Richard Heistand's No. 12 Lexus in fifth position.

The final session of qualifying was for cars in the GTLM class. Laurens Vanthoor qualified on pole driving the No. 912 car for Porsche GT Team, beating teammate Nick Tandy in the sister No. 911 Porsche by 0.052 seconds. Following in third was Connor De Phillippi's No. 25 BMW followed by Dirk Müller in the No. 66 Ford GT in fourth. The Corvette Racing entries started fifth and sixth followed by Ryan Briscoe's No. 67 Ford GT in seventh position. John Edwards in the No. 24 BMW Team RLL entry rounded out the GTLM qualifiers.
