- The Valhalla Spider is expected to debut in November 2026.
- The Valhalla Spider will likely use a removable targa top.
- It should keep the Mercedes-AMG twin-turbo 4.0-liter V8 plus three electric motors for a combined 1,065 horsepower.
Aston Martin's Valhalla coupe has been in customer hands since 2025, and dealers now expect an open-air follow-up. The mid-engined hybrid supercar is widely rumored to be getting a roof job soon.
The Aston Martin Valhalla Spider name has surfaced in enthusiast circles as an open-top companion to the coupe that is capped at 999 units worldwide. The company has not confirmed such a car, and any talk of a specific debut month remains rumor.

What We Know So Far
Aston Martin has only detailed the Valhalla coupe in official material so far. According to TheSupercarBlog, industry chatter points to a Spider variant arriving soon after the fixed-roof car, but there is no verified schedule or formal reveal date.
That timing would put a hypothetical Spider on a collision course with rival open-top plug-in hybrids. The Ferrari 849 Testarossa Spider already covers that ground as a mid-engined plug-in supercar, while the Ferrari Amalfi Spider convertible adds another name to the broader plug-in GT and supercar field.
Lamborghini has not gone there yet with the Revuelto, which recently got a track-focused SV variant instead of a roofless version. Audi has moved in with the limited-run Nuvolari plug-in hybrid supercar, framed as a rival to cars like the 849 Testarossa and Valhalla.
Aston Martin is not new to spreading a nameplate across body styles. The brand's Valiant project and the front-engined Valen show a lineup willing to multiply its halo cars rather than rely on one hero model.
Roof Comes Off, Everything Else Is Still TBD
TheSupercarBlog, citing unnamed sources, a potential Valhalla Spider could use a removable targa-style panel instead of a full folding soft top. Aston Martin has not published any technical information to confirm that layout.
Any open-top version would almost certainly start from the coupe's carbon-fiber monocoque with aluminum subframes, along with its pushrod front suspension and five-link rear setup. Engineers typically add reinforcement in the sills and bulkheads when they delete a fixed roof.
Weight would be the number worth watching. The coupe's dry weight target sits around 3,649 pounds, and keeping an open version close to that figure would be a challenge once roof hardware and extra bracing enter the mix.
The confirmed Valhalla coupe uses a Mercedes-AMG-sourced twin-turbocharged 4.0-liter V8 and a plug-in hybrid system for a total output a little above 1,000 horsepower. Any Spider would likely share that layout, but Aston Martin has not disclosed power figures, pricing, or timing.
Motor1 has reached out to Aston Martin for further comment, and we will update this story if the company responds.
Motor1's Take: A targa Valhalla would broaden Aston Martin's halo lineup and hand collectors a more focused open-top option. It tightens the small club of plug-in hybrid hypercars and turns up the pressure on rivals. Watch final weight, chassis tweaks and track testing. Those results will decide whether the Spider keeps the coupe's balance and earns its premium.
