Nothing else, Only Endurance

WATCH: Valkyrie Hypercar unsilenced at Sebring

The Aston Martin Valkyrie has had it's V12 soundtrack unleashed at its most recent test outing.

IMSA teams have convened this week at Sebring for an official test ahead of the 12 Hours in March, which will be the Valkyrie's debut in the GTP class.

The British LMH is powered by a slightly modified version of the 6.5L naturally aspirated V12 engine found in both the road-going and AMR PRO variants, producing a goosebump-inducing howl.

‘No reason’ hybrid omission will impact Valkyrie: Aston Martin’s Adam Carter
Aston’s new Valkyrie LMH features a 6.5L V12 — but no hybrid unit. Aston’s head of endurance doesn’t believe this will have an impact, though.

Noted by fans during the November Daytona test, that V12 sound was somewhat muffled, and Aston Martin confirmed to Only Endurance that they had "overcompensated" the silencing.

Judging by the video from renowned YouTuber Lanky Turtle, those "safe" silencers have come off, and the V12 has been released. Bravo.

Aston Martin THOR Team Principal Ian James had this to say about the updates to the Valkyrie's tune, “We made a bit of adjustment to the silencing on the car, and everyone keeps coming up and congratulating me so I think we’ve moved in the right direction,” he said.

“It sounds glorious out there! You don’t need the tracker to find where it is on track. GT guys are like, ‘We love it when this car overtakes us.’”
