Despite having been delayed from its original 2022 launch, the Aston Martin Valhalla is still coming. There is, however, a good chance that the Valhalla will arrive in a different form from what Aston Martin originally intended. At the heart of the possible changes is Aston’s brand new 3.0-liter twin-turbo V-6 engine, which may not end up in the Valhalla as intended. Instead, the mid-engined supercar will likely be equipped with a Mercedes-AMG powertrain that Aston Martin now has access to as part of a new technical partnership between the two brands. The revised Aston Martin Valhalla is now scheduled to arrive in 2023.

Aston Martin’s new technical partnership with Mercedes-Benz covers a lot of ground. Not only does Mercedes’ stake in Aston Martin increase from five percent to 20 percent, but the agreement also gives Aston access to a range of combustion, hybrid, and electric powertrains that it can use in its own cars.

The extended partnership now presents the British automaker with new options for the Valhalla. Aston Martin CEO Tobias Moers — he used to be the head of Mercedes-AMG — told Autocar that the company is now “reassessing” the Valhalla with one possible change being a different drivetrain to the concept that was unveiled in 2019.

"We will have the Valhalla with us in the second half of 2023, and it's going to be an amazing car with breathtaking technology,” Moers said. “With the transformational technology agreement with Mercedes-Benz, there are other chances for us regarding combustion engines, but we still have an electrified drivetrain.”

On one hand, now that Aston Martin has access to all these AMG powertrains, it’s a sensible move to look into using them, especially if it means raising the performance potential of the Valhalla so it can better compete with the likes of the Ferrari SF90 Stradale. The automaker’s goal of electrifying 90 percent of its lineup by 2030 also gets a massive shot in the arm. This includes the PHEV version of the DBX, which could now use a version of the electrified powertrain that Mercedes-AMG is using in the 63e and 73e models.

On the other hand, the fate of Aston’s new turbo V-6, codenamed TM01 in honor of Tadek Marek, is now up in the air. It could be shelved before ever making it into production.

Moers declined to give more information, but he did say that prospective customers of the Valhalla have been informed of the possible changes. A new version of the concept will be shown to buyers within the next four months.
