A mid-summer favorite, The WeatherTech® International Challenge with Brian Redman presented by HAWK is one of the largest vintage racing events in the United States and features over 400 cars competing in several groups. The four-day weekend will also showcase a historic CAN-AM race, which is the highlight of this year’s event as an impressive field of cars is expected to gather in celebration of CAN-AM’s 53rd Anniversary. Additionally, 2019 will be a special MG Focus Event during the weekend.

During the 1950s “Golden Age” of American sports-car racing, one of the most competitive specials was the Echidna, which ruled SCCA C- and B-Modified competition. Just three Echidnas were built in all and this year all three Echidnas will be at the WeatherTech International Challenge with Brian Redman presented by HAWK to celebrate their 60th anniversary of the Echidnas 1959 B/Modified National Championship.

In addition, the Masters Historic Formula One USA grid is joined by the brand-new Masters Endurance Legends USA series at the WeatherTech International Challenge with Brian Redman presented by HAWK. Don’t forget to mark your calendars as the Concours d’ Elegance in downtown Elkhart Lake on Friday for race cars and Saturday night for streetcars is a can’t miss event for any enthusiast.
