Cadillac Racing says its first electric race car is almost ready for the 24 Hours of Daytona event in January after passing critical testing and development milestones. Since July, the V-LMDh has gone through nearly 12,000 miles (19,000 km) of on-track testing, including a 24-hour test at Sebring International Raceway.

Cadillac collected data on nighttime operation and durability on the bumpy 3.7-mile circuit. Program manager Laura Wontrop Klauser claimed Sebring was the perfect testing ground for the V-LMDh ahead of its competitive debut at Daytona. “To complete that endurance test was extra motivation for our team and provided a sense of accomplishment,” Klauser said in a statement. “We still have a lot to do in a short time, but we are at the point where we are fine-tuning many things.”

The car is also slated to take part in the 24-hour race at Le Mans in June. Cadillac plans to run it in the IMSA WeatherTech SportsCar Championship and the FIA World Endurance Championship. A final test will take place next week at Daytona as part of mandatory evaluations for all manufacturers intending to take part in the IMSA’s new Grand Touring Prototype class. Cadillac Racing will reveal the final competition version of the three V-LMDh race cars, including liveries (and hopefully a new name), in mid-January.
