It's been four years since the awe-inspiring Mercedes-AMG One debuted as a concept, but the final production model still isn't ready. Deliveries of the F1-inspired hypercar were due to start later this year, but the AMG One has reportedly been delayed until early next year, giving the Aston Martin Valkyrie a head start.

While the hypercar was on display at the Munich Motor Show, AMG didn't announce any updates or a revised delivery schedule. As testing continues, the Mercedes-AMG One has been caught testing on the public road and was caught on camera by CarSpyMedia.

The prototype is wrapped in the now-familiar motorsport-inspired red, grey and white livery. At the start of the video, the test driver appears to have taken a wrong turn and is forced to turn around on a dirt road. This is not the hypercar's natural habitat, but we soon get to see it unleashed onto the track.

The camera car then follows the AMG One on the road, giving us a clear view of the rear, which incorporates a centrally mounted exhaust, an aggressive diffuser, and a retractable rear spoiler. After a warm up on the road, the AMG One goes into full attack mode at the Nurburgring, allowing us to hear its 1.6-liter V6 hybrid engine roar. Sourced from a Mercedes Formula 1 car, the AMG One's electrified V6 generates a colossal 1,021 horsepower.

It sounds great, though if we're honest it doesn't sound as dramatic as the naturally-aspirated Pagani Huayra R we heard a few weeks ago. Even though it's wrapped in camouflage, the AMG One looks like an F1 car for the road, with its roof-mounted scoop, shark fin, and fender flaps.

Only 275 examples are planned for production, each costing $2.72 million. Despite the hefty price tag, Mercedes-AMG had no trouble selling every one of them. If you can't wait for the Mercedes-AMG One to arrive, you'll be able to take the F1-inspired hypercar for a virtual spin in Forza Horizon 5 in November.
