IMSA Continental Tire SportsCar Challenge
The IMSA Continental Tire
SportsCar Challenge enters an exciting
new phase in 2018, with the complete
adoption of GT4 technical regulations
for the headlining Grand Sport
(GS) class and the introduction of the
new TCR (Touring Car) class alongside the continuation of the ultra-competitive
Street Tuner (ST) class.
All three classes will compete in a 10-race Continental Tire SportsCar
Challenge schedule that once again takes the series to iconic road racing
venues across North America as companion events to the IMSA
WeatherTech SportsCar Championship. As has been the case for the
past several years, the Continental Tire Challenge typically will provide
the featured race on the day before each event weekend’s WeatherTech
Championship event.
“The Continental Tire Challenge took an encouraging step forward in
2017 with the introduction of GT4 technical regulations for the GS class,”
said IMSA President Scott Atherton. “In 2018, we will move to full GT4
specs for GS and will see the introduction of several impressive new race
cars from fantastic manufacturers.
“At the same time, we will bring TCR competition to the Continental Tire
Challenge and another outstanding mix of race cars and manufacturers
that we expect will resonate with our race fans. And the ST class continues
to provide outstanding competition via its established platform and
battle-tested competitors.”
The 2018 season opened at Daytona International Speedway on
Friday, Jan. 26 with a four-hour race. The 2018 season will include two
four-hour events, with the other slated for Watkins Glen International on
Saturday, June 30.
Eight Continental Tire Challenge events will be two hours in length,
beginning with the second round at Sebring International Raceway on
Friday, March 16.
Every race in 2018 again will be televised by FOX Sports on a tape-delayed
basis, and will be streamed live on IMSA.com and the IMSA mobile
app.
