Aston Martin could reveal a Valhalla Spider in November 2026, according to industry chatter cited by TheSupercarBlog. The rumored open-top supercar would follow the fixed-roof Valhalla, which has been in customer hands since 2025, but Aston Martin has not confirmed the model or a debut date.

The Valhalla Spider is expected to become an open-air companion to the mid-engined hybrid coupe. The existing Valhalla is limited to 999 units worldwide, giving Aston Martin another potential halo variant as it expands its range of exclusive performance cars.

Possible targa roof layout

Early reports suggest the Spider could use a removable targa-style roof panel rather than a conventional folding soft top. Aston Martin has released no technical information confirming that design, so the roof mechanism remains one of the key unanswered questions surrounding the car.

An open-top Valhalla would likely retain the coupe's carbon-fiber monocoque and aluminum subframes. The coupe also uses pushrod front suspension and a five-link rear suspension. Removing a fixed roof would typically require additional reinforcement around the sills and bulkheads, potentially affecting the Spider's weight and chassis tuning.

The Valhalla coupe has a dry-weight target of approximately 3,649 pounds. Keeping the Spider near that figure could prove difficult once the roof hardware and structural bracing are added. Final weight, suspension revisions and track testing will be important indicators of how closely the open car matches the coupe's dynamics.

1,065-hp plug-in hybrid powertrain

The rumored Spider is expected to use the Valhalla coupe's Mercedes-AMG-sourced twin-turbocharged 4.0-liter V8 and plug-in hybrid system. The setup combines the V8 with three electric motors for a stated total of 1,065 horsepower.

Aston Martin has only formally detailed the fixed-roof Valhalla so far. It has not disclosed whether the Spider would receive different calibration, additional performance equipment or changes to the hybrid system. Pricing, production volume and customer availability also remain unconfirmed.

Potential rivals and timing

If the November 2026 timing proves accurate, the Valhalla Spider would join a small group of open-top or open-air plug-in hybrid performance cars. The Ferrari 849 Testarossa Spider already occupies that space, while the Ferrari Amalfi Spider broadens the field into plug-in hybrid grand touring and supercar territory.

Lamborghini has not introduced a roofless Revuelto, instead developing a track-focused SV variant. Audi has also entered the limited-run plug-in hybrid supercar market with the Nuvolari. For Aston Martin, a Spider would extend the Valhalla nameplate while adding another collectible body style to its halo lineup.

Until Aston Martin issues an official announcement, the November debut remains unverified. TheSupercarBlog's report is currently the basis for the expected timing, and further details about the roof, weight, performance and price are still unknown.
