Cadillac V-LMDh aims to make noise at the Roar

Before the aggressive and distinctively Cadillac V-LMDh rounds into view, the unmistakable throaty sound is its calling card. Authentic American V8.

Cadillac, the only LMDh manufacturer with a naturally aspirated engine, will seek to build on its legacy of success in the 61st Rolex 24 At Daytona -- the opening round of the IMSA WeatherTech SportsCar Championship season and introduction of the hybrid race cars in the Grand Touring Prototype class.

Three Cadillac V-LMDh race cars will make their debut this week at the Roar Before the Rolex 24. Cadillac will seek its fifth overall victory in the race 2017.

The twice-around-the-clock race is Jan. 28-29 at Daytona International Speedway. The prelude Roar commences with the first of five on-track practice sessions at 11 a.m. ET Jan. 20.

The starting grid will be determined by the qualifying format used at other IMSA races – a 20-minute session -- on the 3.56-mile, 12-turn road course. Peacock will provide streaming coverage of qualifying starting at 1:20 p.m. Jan. 22.

“Two years of planning, preparation and perseverance have brought Cadillac Racing to this place and time – the start of a new and exciting era for the brand, IMSA and the WEC,” GM sports car racing program manager Laura Wontrop Klauser said. “We’re thankful for the cooperation and consideration of dozens of GM personnel, our teams, partners, suppliers, the sanctioning bodies and the other OEMs to get to this point. 

“This has been an intense process, but an extremely rewarding one. Our development process has been like running the Rolex 24 at least five times in a row. It felt like almost every test we were running a 24-hour race with the hours we were at the track and how hard everyone was working. We’re now looking forward to seeing the Cadillac V-LMDh cars on the racetrack in competition and, of course, in the winner’s circle.”

Since its shakedown in early July 2022, the Cadillac V-LMDh has completed more than 12,000 miles of on-track development in addition to numerous hours of development of the 5.5-liter DOHC V8 on dynamometers at the GM Performance and Racing propulsion facility in Pontiac, Michigan.

“Everyone wishes they had an extra month or two and it’s just the way of the new formula. I guess the best way to do it is to rip the band aid off and get racing,” said Earl Bamber, co-driver of the No. 02 Cadillac V-LMDh.

Since 2017, Cadillac has been competing at the forefront of American sports car racing in the IMSA prototype class. In the 2017-2022 DPi era, Cadillac Racing achieved 27 wins (most of any manufacturer), 84 podium finishes, plus:

* Winning the IMSA WeatherTech SportsCar Championship three times: 2021, 2018 and 2017

* Winning the Rolex 24 at Daytona four times in a row: 2020, 2019, 2018 and 2017

* Winning the Michelin North American Endurance Cup four times: 2020, 2019, 2018 and 2017

* Winning three Team and Driver Championships

Prior to competing in the IMSA WeatherTech SportsCar Championship, Cadillac competed in the World Challenge Championship, earning five Manufacturer Championships (2014, 2013, 2012, 2007, 2005) and five Driver Championships (2015, 2014, 2013, 2012, 2005).
