Aston Martin is shaking down its Valkyrie AMR-LMH endurance race car, and no surprise, it sounds wonderful. The brand posted a very short video clip of the car running at both Silverstone and Donnington Park, and while there's unfortunate music in the background, we get a very good listen to its naturally aspirated 6.5-liter Cosworth V-12. We can't wait to hear this echoing down the Mulsanne at Le Mans.
