DAYTONA BEACH, Fla.—IMSA’s newly-renamed Weathertech SportsCar Championship (né Tudor United SportsCar Championship) opened Daytona International Speedway Nov. 17 and 18 to let teams run their first tests with their 2016 equipment.
Included were the new Ford GT, BMW’s new M6, a handful of new GT3 entries which the series is admitting starting in 2016, and a SpeedSource Lola-Mazda with a 2-liter turbocharged gasoline power plant in place of the turbo-diesel. Also, the Shank Racing Ligier was out testing its new 3.5-liter Honda turbo. The DeltaWing, a few Coyote-Corvettes, and a few LMPC Orecas filled out the field.
