IMSA WeatherTech SportsCar Championship

Daytona, Sebring, Watkins Glen or Road America - the season in the North American IMSA WeatherTech SportsCar Championship includes some of the most significant circuits in international motor racing. The International Motor Sports Association (IMSA) created the renowned series in 2013 from the amalgamation of the American Le Mans Series and the Rolex Grand-Am Series. Since 2016, it has been running its race events under the WeatherTech SportsCar Championship (WTSC) banner. Next to prototypes (DPi and LMP2 categories) and GTLM cars, various brands are also competing for valuable points in the GTD championship with GT3 machinery.

For Mercedes-AMG Motorsport, the internationally highly acclaimed and hard-fought series has been nothing but a success story. Already in 2017, the debut year of the Mercedes-GT3, Mercedes-AMG Team Riley Motorsports managed to secure the GTD double of the drivers’ and teams’ championship titles in the Michelin Endurance Cup (formerly Tequila Patrón North American Endurance Cup). Moreover, the manufacturers’ title in this category also went to Affalterbach. The Michelin Endurance Cup is the series’ internal endurance classification that includes the results from the classic endurance races at Daytona, Sebring, Watkins Glen and Road Atlanta. The victories in this championship could be repeated in the two following years 2018 and 2019, enabling the team led by manager Bill Riley to start the season again as the defending champion and meanwhile three-time endurance title winner. Therefore, the goal for 2020 is clear: the fourth consecutive triple title win. 

IMSA Michelin Pilot Challenge

Next to the WTSC, the IMSA Michelin Pilot Challenge (MPC) is also part of the promoter’s portfolio and has its races on the same weekends. In 2018, one year after the Mercedes-AMG GT3 made its IMSA competition debut, the Mercedes-AMG GT4 first raced in the GT4 series and since has had considerable success.

One of the highlights of the GT4 programme in the US so far was the teams’ and drivers’ championship title win by Team TGM and drivers Hugh Plumb and Owen Trinkler (both USA) in the debut year 2018. In 2019, Mercedes-AMG won the manufacturers’ title in the GS class by virtue of a consistent performance by all Customer Racing Teams.

2020 IMSA season

Traditionally, the IMSA WeatherTech SportsCar Championship gets underway with the Rolex 24 At Daytona. For Riley Motorsports and Mercedes-AMG Motorsport, that is where the mission title defence started. In 2019, the triple of drivers’, teams’ and manufacturers’ title in the GTD class of the Michelin Endurance Cup was achieved with the Mercedes-AMG GT3 for the third consecutive year. At the season opener, the quartet of Lawson Aschenbach (USA), Felipe Fraga (BRA), Ben Keating (USA) and Gar Robinson (USA) had a mixed weekend. At the legendary Daytona International Speedway, the #74 Riley Motorsports Mercedes-AMG GT3 ended up in eleventh place of the GTD class.

In the four-hour opening race of the IMSA Michelin Pilot Challenge that took place on the support programme of the classic endurance race, Mercedes-AMG Motorsport achieved a convincing 1-2-3 finish. Victory went to Customer Racing Team Riley Motorsports (#35) with drivers Jeroen Bleekemolen (NED), Jim Cox and Dylan Murry (both USA), followed by Winward Racing (#57) with drivers Bryce Ward (USA) and Philip Ellis (GER) in second place. Another Winward Racing Mercedes-AMG GT4 (#4) with drivers Russell Ward (USA) and Indy Dontje (NED) completed the clean sweep of the podium. With the triple victory for the Mercedes-AMG GT4, Mercedes-AMG Motorsport successfully started off its mission title defence in the series’ manufacturers’ standings. For the first time ever, the Mercedes-AMG GT4 locked out all the three podium slots in a race in North America.
