Michelin Road America Notebook

Introducing the Michelin Scorecard

Michelin has created a scorecard showcasing the breadth of manufacturer success in IMSA. 14 manufacturers have won so far during the 2022 IMSA season with all 17 reaching the podium. Porsche has the most with seven wins across three classes. Click Here for the scorecard.

Competitive Final Chapter

As seen in the Michelin Scorecard, Acura and Cadillac are tied in the standings with each having four wins and four poles in 2022. Just two more races of the DPi era remain as IMSA shifts to GTP for its top class in 2023.

Currently, the No. 60 Meyer Shank Racing Acura leads Wayne Taylor Racing’s No. 10 Acura by just 56 points and Chip Ganassi’s No. 01 Cadillac by 148 points.

The Band is Back Together

Road America features the only IMSA WeatherTech Sprint Cup race with all five classes. There is far less time to make up for mistakes made on pit lane or in traffic compared to Michelin Endurance Cup races where all five classes routinely compete.

Busy Weekend for Michelin Race Tires

IMSA at Road America attracts strong entry lists. The WeatherTech Championship features 37 entries, Michelin Pilot Challenge has 40 entries and Porsche Carrera Cup North America contains 34 entries. MotoGP also races at Silverstone for the Monster Energy British Grand Prix.

Up, Down and Around

Road America is the longest circuit on the IMSA schedule. The four-mile course features 14 turns, 3 long straightaways and challenging corners.

Along the way, cars climb 5 times and descend 7 times each lap—a total of 20 stories up and 20 stories down every lap. The four-mile-long lap and steep uphill run to the pit lane makes accurate fuel calculations especially critical.

High Speeds

Road America is one of the fastest tracks on the IMSA schedule, with Canadian Tire Motorsport Park, Daytona International Speedway and Watkins Glen International.

Earlier this season, Tom Blomqvist set the fastest qualifying lap in IMSA WeatherTech SportsCar history at CTMP with a 137.472 miles per hour average.

The quickest IMSA lap at Road America came in 2019 when Dane Cameron ran a qualifying lap speed average of 134.045 miles per hour.

Double the Fun for Pilot Challenge

The Road America 240 is the second of two four-hour races on the Michelin Pilot Challenge schedule. In January, at Daytona, RS1 won the GS class in a Porsche and KMW Motorsports took the victory in TCR with an Alfa Romeo.

The typical length of an IMPC race is two hours, so consistency by drivers and their pit crews typically serves as the path to victory lane in these longer races.
