Cadillac’s much rumored return to prototype racing has become reality in late 2016, when the American luxury brand unveiled its new race car for the IMSA series. Dubbed DPi-V.R, it’s Cadillac’s first prototype race car in 14 years and competes in IMSA’s new DPi class starting early 2017. The new category replaces 2016’s Prototype class in the IMSA WeatherTech SportsCar Championship and brings revised regulations to the series. One of the most important changes is that the IMSA now allows automakers to produce their own designs, meaning prototypes can have their own identities instead of sharing almost identical body shells. Mazda has already taken advantage of this with the RT24-P, which uses the company’s Kodo styling language, but Cadillac has also used cues seen on its road cars for the DPi racer.
