The 2019 Road Race Showcase at Road America was a sports car race sanctioned by the International Motor Sports Association (IMSA). The race was held at Road America in Elkhart Lake, Wisconsin on August 4, 2019, as the ninth round of the 2019 WeatherTech SportsCar Championship, and the fifth round of the 2019 WeatherTech Sprint Cup.

Background[edit]

Road America, where the race was held.

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.[1] It was the sixth consecutive year the event was held as part of the WeatherTech SportsCar Championship. The 2019 Road Race Showcase at Road America was the ninth of twelve sports car races of 2019 by IMSA, and it was the fifth of seven rounds held as part of the WeatherTech Sprint Cup.[2] The race was held at the ten-turn 4.048 mi (6.515 km) Road America in Elkhart Lake, Wisconsin on August 4, 2019.[3]

During this race weekend, IMSA holds their "State of the Series" annual press conference, in which they confirm and announce their future plans for the series they sanction.

On July 24, 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 the same as they were in the previous event at Lime Rock Park. In the Daytona Prototype International (DPi) class, after winning the previous two events of the championship, the Mazda RT24-P was hit with a two-liter fuel capacity reduction and a power reduction of 17 horsepower and restriction in higher-RPM turbo boost, as well as being made 20 kilograms heavier. The Cadillac DPi-V.R was also made 20 kilograms heavier, but it received a 0.6 millimeter increase in its restrictor diameter, as well as an increase of 11 horsepower and a fuel capacity increase of one liter. The Acura ARX-05 was made 10 kilograms heavier. In the GT Daytona class (GTD), the constraints of the McLaren 720S GT3 were once again drastically improved, with a 30 kilogram weight reduction and a power increase of eight horsepower, and turbo boost increase. The Ferrari 488 GT3 was given improvements in the same fields, albeit smaller, along with a one liter fuel capacity increase. After winning the 6 Hours of the Glen and finishing 2nd in the previous two championship-scoring rounds, The Acura NSX GT3 was made 20 kilograms heavier.[4]

Before the race, Dane Cameron and Juan Pablo Montoya led the Drivers' Championship with 207 points, ahead of Pipo Derani and Felipe Nasr in second followed by Hélio Castroneves and Ricky Taylor in third with 198 points.[5] In LMP2, Matt McMurry led the Drivers' Championship with 165 points, 2 points ahead of Cameron Cassels and Kyle Masson.[5] Earl Bamber and Laurens Vanthoor led the GTLM Drivers' Championship with 218 points; the duo held an eight-point advantage over Patrick Pilet and Nick Tandy in second.[5] With 183 points, Mario Farnbacher and Trent Hindman led the Drivers' Championship, 30 points ahead of Bill Auberlen and Robby Foley in second followed by Patrick Long in third with 151 points.[5] Acura and Porsche were leading their respective Manufacturers' Championships, while Acura Team Penske, PR1/Mathiasen Motorsports, Porsche GT Team, and Meyer Shank Racing each led their own Teams' Championships.[5]

Entries[edit]

On the same day as the Balance of Performance bulletin, the entry list for the event was released, featuring 35 cars. There were 10 entries in DPi, two in Le Mans Prototype (LMP2), eight cars in GTLM, and 15 cars in GTD. After suffering a heavy crash at the Mobil 1 SportsCar Grand Prix, Cadillac DPi customer team Juncos Racing decided not to take part in the Road America event, for not having built a new chassis in time. They were initially intending to take part in the race. In GTLM, Corvette Racing regular driver Tommy Milner would make his return after being substituted by endurance-only driver Marcel Fässler in the previous two races.[6] In GTD, Starworks Motorsport made their return for Road America, with their regular drivers Ryan Dalziel and Parker Chase after missing the previous two events. Porsche junior drivers Matt Campbell and Dennis Olsen made appearances for Pfaff Motorsports and Wright Motorsports, respectively, after driving for the opposite teams in Lime Rock Park.[7][8] In GTLM, Corvette Racing regular driver Tommy Milner would make his return after being substituted by endurance-only driver Marcel Fässler in the previous two races.[6]

Qualifying[edit]

Saturday's early afternoon qualification session was broken into three sessions that were scheduled for 15 minutes each.[9] The first was for cars in the GTD class. Ben Keating qualified on pole for the class driving the No. 33 car for Mercedes-AMG Team Riley Motorsports, beating Corey Lewis in the No. 48 Paul Miller Racing Lamborghini by more than four-tenths of a second.[25] Following in third was Matt Plumb's No. 76 McLaren with the No. 9 Pfaff Motorsports Porsche Zacharie Robichon in fourth.[26] Trent Hindman's No. 86 Acura completed the top five followed by Robby Foley in the No. 96 BMW in sixth.[27] The session ended prematurely due to lightning being near the area.[25]

The second session was for cars in the GTLM class. Tom Blomqvist set the fastest time driving the No. 25 car for BMW Team RLL.[26] However, both BMW Team RLL entries were sent to the back of the GTLM field after both cars failed post post-qualifying technical inspection where it was discovered that the BMWs were found to not have complied with mandated ride height.[28] As a result, Oliver Gavin's No. 4 Corvette was promoted to pole position followed by Richard Westbrook's No. 67 Ford GT in second, and Dirk Müller in the sister No. 66 Ford GT in third position.[29][30]

The final session of qualifying was for cars in the LMP2 and DPi classes. Dane Cameron qualified on pole overall driving the No. 6 car for Acura Team Penske, beating teammate Hélio Castroneves in sister No. 7 Acura by 0.016 seconds.[25] The two Mazdas were third and fourth (the No. 77 car driven by Jarvis in front of the No. 55 vehicle of Bomarito).[10] Simon Trummer took fifth place in the No. 84 Cadillac.[10] In LMP2, The Performance Tech Motorsports Oreca of James French set the fastest time in the session. McMurry stopped on track with 8 minutes remaining after spinning at turn three and getting stuck in the gravel trap. McMurry was able to restart, but lost his two fastest laps for causing a red flag.[10][27] Both entries changed their starting driver. As a result, the PR1/ Mathiasen Motorsports car would start the race from pole position.[31]
