Aston Martin CEO Andy Palmer has taken to social media to share the scream created by the upcoming Valkyrie’s naturally aspirated 6,5-litre V12.

The tweet includes a 20-second clip that gives us our first listen to the mid-mounted, high-revving V12, which the Gaydon-based brand has sourced from the folks over at Cosworth.

Of course, Cosworth has already promised that the Valkyrie’s 12-pot will be the world’s most powerful naturally aspirated engine used in a road car (thus theoretically taking the title from the Ferrari 812 Superfast), even if final figures have yet to be confirmed.

The Valkyrie was initially known as the AM-RB 001, a nod to the fact is was developed by Aston Martin and Red Bull.
