Hear Cadillac Racing’s LMDh 5.5L V8 roaring down the track

Cadillac Race | Test V-LMDh | Cadillac Series DRAW

it gets a months since we signed up with Cadillac, but it looks like the Cadillac Racing team and their latest addition, IMSA’s new GTP V-LMDh that debuted in January, are ready to go. The proof is in the sound.

Sure, this is just a one minute video and it takes almost 20 seconds before we get to the good part when you hear the car start up. The car that allows this is almost humorous and shrill electric hiss (like those of Formula E cars), before the 5.5L-v8 engine kicks in. Then it means. That is a requirement. Its race.

The road is long for the Grand Touring Prototype candidates, with Porsche leads in development and homologation to the mandatory hybrid battery for every car. Then in June, BMW carthen Cadillac and finally Acura all the way in August, have revealed their car(s) and the hopeful challengers are ready for the race. Their biggest hurdle at the time was that they needed to start experimenting and work out the glitches in setting up the factory-built engines for the series to work well with the hybrid system.

We all get a little sneak peek of where the manufacturers are growing, after the final race of the 2022 IMSA season at Road Atlanta. There, the LMDh cars completed their first round of group testing, despite Porsche’s absence (since they’ve already traveled more than enough miles. Maybe that’s a nice gesture?). But next week, the group will all of were in Daytona for the final round of testing, before they reconvened at the same track in January for Roar Before the 24 and shortly thereafter, Rolex 24 at Daytona.

I haven’t had a chance to listen to any of these cars live yet, but I will next week. My list of what to see and experience – and who to talk to — is extensive. However, I’m curious, would you be interested to hear something from the testing process? What are you most looking forward to as this new Prototype class enters the season? Let me know what you’d like to see or hear about in the comments section below.
