2016 WeatherTech SportsCar Championship
The 2016 WeatherTech SportsCar Championship season is the third season of the WeatherTech SportsCar Championship organized by the International Motor Sports Association (IMSA), and the 46th season of IMSA-sanctioned GT Championship sportscar championships tracing its lineage to the 1971 IMSA Camel GT season. It will begin on January 30 with the 24 Hours of Daytona.
The class structure remained largely unchanged from 2015, with the major change coming in GTD which will now run full GT3 spec machinery.
