Using a normally aspirated, 600hp version of the 6.2-liter V8 found in supercharged form in the Cadillac CTS-V as well as in normally aspirated form in the Escalade, the DPi-V.R uses styling cues from the current ATS-V and CTS-V.

Andrew Smith, Global Cadillac Design executive director said: “The DPi-V.R racecar was an exciting new canvas for the Cadillac design and sculpting team.

"The studio embraced the opportunity to interpret the Cadillac form language, line work and graphic signature for this premier prototype racing application.

“Every detail of the final design was selected to support the car’s on-track performance and unmistakable Cadillac presence.”

These include the vertical lights, the feature line on the side of the body, the canopy graphic, cooling vents and air intake in the shape of the Cadillac crest.

Johan de Nysschen, president of Cadillac said: “Cadillac is proud to return to the pinnacle of prototype racing in North America after a 14-year absence,” said Johan de Nysschen, president of Cadillac.

“Cadillac’s V-Performance production models – the ATS-V and CTS-V – are transforming our brand’s product substance, earning a place among the world’s elite high performance marques.

"The Cadillac DPi-V.R further strengthens our V-Performance portfolio, placing Cadillac into the highest series of sports car racing in North America.”

Cadillac joins Mazda and Nissan as confirmed DPi manufacturers for IMSA’s Prototype class, which will also include international LMP2 prototype chassis from Riley/Multimatic, Ligier, ORECA and Dallara, powered by single-specification Gibson V8 engines.
