Soundcheck: Aston Martin Valkyrie begins to scream

6.5-liter Cosworth V12 sounds like Formula 1 is supposed to sound

In July, Aston Martin published the first video of the Valkyrie on track at Britain's Silverstone Circuit during the Formula One Grand Prix weekend there. Test driver Chris Goodwin didn't push the 1,160-horsepower coupe to its limits, merely massaging the throttle for the camera a few times. The English carmaker headed back to Silverstone this month with a group of guests in tow, and this time the test driver put a little more muscle into the fly-bys. Since the track was wet, the soundtrack still can't be considered the ultimate experience, but even so, the 6.5-liter Cosworth V12 sounds exceptionally good.

This new video injects a high-pitched wail that was missing in July, the kind of wicked, soaring keen that jellies one's organs and notifies the mind of blinding terrors on approach. In fact, the Valkyrie now makes all the noises Formula 1 fans wished the F1 race cars could make. That's no hyperbole, either. Compare the modern Cosworth to the 3.5-liter Honda V12 in the 1991 McLaren MP4/6, the resemblance is clear. Remove the street-legal equipment on the Aston Martin and let Goodwin uncork it, as we expect to happen in next year's World Endurance Championship, and it's clear the WEC might have the best sounding racers in all of motorsport.

Deliveries are scheduled to begin before the end of the year, so Aston Martin should be wrapping up its validation testing on Verification Prototype 1 if it hasn't already. After that come competition entries into the FIA World Endurance Championship (WEC). And after that, someone will need to convince at least one owner to drive the Valkyrie on the street so that we can all enjoy the noise.
