Cadillac Racing today has pulled back the covers on its new prototype for 2023 that will replace the championship-winning Cadillac DPi-V.R in IMSA’s WeatherTech SportsCar Championship.

Dubbed the “Project GTP Hypercar,” a number of similarities and differences to the current DPi can be found with the car that will campaign by Chip Ganassi Racing and Action Express in IMSA’s GTP class starting at January’s Rolex 24 At Daytona.

Just like the current DPi-V.R, the GTP is built by Dallara in Italy. It also features a brand-new double-overhead cam 5.5-liter naturally aspirated V8, which is the same displacement as the motors found in the DPi-V.R. The engines are expected to be built within the GM Racing family, which would be a change from the DPi-V.R which uses Earnhardt Childress Racing to prepare and support its powerplants.

Together with IMSA’s spec energy recovery system connected to the 5.5-liter V8, the 680hp GTP will serve as Cadillac’s first hybrid prototype.
Compared to the DPi-V.R which bears a strong resemblance to the stock Dallara P217 LMP2 chassis it’s based upon, the new GTP car makes a strong departure with its styling as heavy Cadillac road car cues are featured at the front of the prototype.

Cadillac Design, Cadillac Racing and its selected chassis partner Dallara have co-developed the shape of the vehicle to incorporate identifiable brand characteristics such as vertical lighting and ‘floating blades’.
“Cadillac will be competing again on the world racing stage, and we are all thrilled to return to Le Mans after 20 years,” said Rory Harvey, Vice President of Global Cadillac.

“By competing in both the 2023 IMSA and WEC championships, Cadillac Racing has the opportunity to demonstrate its capability, craftsmanship and technology.”
Chris Mikalauskas, Cadillac’s lead exterior creative designer, added:
“The Project GTP Hypercar is a unique convergence of form and function and showcases Cadillac’s future performance aesthetic.
“We have plenty more to come, from the upcoming race car to amazing production vehicles.”

Cadillac announced its LMDh program in August 2021 when it named Action Express Racing and Chip Ganassi Racing as its partner teams for the project.
It issued a teaser image of the car’s design in February, with that depiction of the front end bearing resemblance to part of the full-car render issued on Wednesday.
The 5.5-liter dual overhead camshaft V8 engine will be “all-new” according to Cadillac and follows on from the same displacement V8 found in the company’s DPi prototype for the WeatherTech Championship.

Cadillac is currently targeting a “summer” rollout, after previously hoping to conduct the car’s first shakedown in the spring.
The next two months are set to be a hive of activity in terms of prototype testing, with Ferrari planning to roll out its hybrid LMH car in July and BMW also getting closer to the initial shakedown of its LMDh machine, which like the Cadillac is based on a Dallara.

“Competing for the overall win at Le Mans with an iconic American brand like Cadillac is an honor,” said GM sports car racing program manager Laura Wontrop Klauser.
“The entire team is excited to continue building Cadillac’s racing legacy by competing against the very best internationally and in the world’s toughest race.”
