One of the star cars at the 2021 Goodwood Festival of Speed was the awe-inspiring Aston Martin Valkyrie. Aston Martin's race car for the road attracted a huge crowd at the event and we even got to hear its glorious V12 rev its lungs out.

Attendees also got to see the Valkyrie in action as it roared up the challenging Goodwood Hill Climb, but the hypercar's public debut didn't go according to plan. During its second run at the hill, the Valkyrie suffered a mechanical fault and broke down without warning, coming to a grinding halt on the track. Luckily, the hypercar was still able to move under its power and reverse off the track.

Speaking with Autosport, Aston Martin chairman Lawrence Stroll confirmed what happened. Apparently, a £5 ($6.89) part caused the $3.25 million Valkyrie to break down.

"There was some small electrical glitch, some £5 part between the low voltage battery and the high voltage battery that decided not to work for some reason at that moment," said Stroll. "We've never had that problem in testing. [We're] kind of happy it happened now, we hadn't seen it before, and it's something we get from an external source. So we understood it and repaired it immediately." Stroll also confirmed that customer deliveries for the Valkyrie are still on track for September.

Only 150 examples of the Valkyrie are being built and each has already been sold. The track-only Valkyrie AMR Pro will be even more exclusive, with only 25 units planned for production.

Powering the Valkyrie is a naturally aspirated 6.5-liter Cosworth V12 that revs all the way to 11,000 rpm paired with a Formula 1-style hybrid boost system. Combined, this setup generates a combined 1,160 hp, enabling the Valkyrie to rocket from 0-60 mph in under three seconds and reach a top speed of over 200 mph.
