The Aston Martin Valhalla Spider brings open-top driving to the British automaker’s first plug-in hybrid supercar without sacrificing the coupe’s 217-mph top speed. Powered by a 1,064-horsepower hybrid system, the new convertible combines revised aerodynamics with the same performance-focused engineering as its fixed-roof counterpart.
The Valhalla enters a competitive segment that includes the Ferrari 849 Testarossa and Lamborghini Revuelto. With the Spider, Aston Martin aims to expand the model’s appeal while preserving the performance figures that distinguish the coupe.
Aston Martin Valhalla Spider Matches the Coupe’s Top Speed
Unlike many supercars offered in both coupe and convertible configurations, the Valhalla Spider retains the coupe’s maximum speed of 217 mph, even with the roof removed. Open-top models often have lower top speeds because of increased aerodynamic drag and additional weight.
Aston Martin’s flagship Valkyrie illustrates that challenge. The Valkyrie Coupe has a listed top speed of 220 mph, while the Valkyrie Spider is rated at more than 217 mph with the roof installed and more than 205 mph with the roof removed.
Despite the Valkyrie Spider producing more horsepower from its naturally aspirated hybrid V12, the Valhalla Spider becomes Aston Martin’s fastest open-cockpit model ever.
A 1,064-Horsepower Hybrid Powertrain
The Valhalla Spider uses the same powertrain as the coupe: a 4.0-liter twin-turbocharged V8 engine paired with three electric motors. Together, the components produce a combined output of 1,064 horsepower.
Revised aerodynamic features help the open-top model maintain its performance. These include a rear snorkel that is 35 mm (1.38 inches) taller and a wind deflector designed to direct airflow above the occupants while supplying cooling air to the engine intake.
Aston Martin has also recalibrated the active aerodynamics and electronic stability control systems for driving with either the roof installed or removed.
Roof Options Affect the Valhalla Spider’s Performance
Although the Valhalla Spider can retain its full 217-mph top speed, the roof configuration matters. The optional carbon-fiber hardtop preserves the maximum speed, while the standard fabric roof limits the car to 124 mph when fitted.
In the U.S., the carbon-fiber hardtop reportedly comes standard, allowing American customers to retain the model’s full top-speed capability with the roof installed.
The Spider also introduces standard carbon-fiber Touring Seats. Customers who prefer the coupe’s sportier seats can keep them at no additional cost.
Production Numbers, Pricing and Delivery Timeline
Aston Martin has not disclosed the Valhalla Spider’s production numbers or official pricing. However, reports indicate that the open-top version will account for approximately 25% of the Valhalla’s planned 999-unit production run, equivalent to roughly 250 examples.
The Valhalla Coupe starts at slightly more than $1 million in the United States. Because Spider versions traditionally command higher prices, the new convertible is expected to carry a premium, although its final price has not been announced.
The Valhalla Spider is scheduled to make its global debut at the 2026 Concours at Wynn Las Vegas this weekend. Customer deliveries are expected to begin in the third quarter of 2027.
How the Valhalla Spider Compares With Ferrari and Lamborghini
The Ferrari 849 Testarossa is one alternative in the plug-in hybrid supercar segment and is available in both coupe and open-top configurations. Unlike the Aston Martin Valhalla, the Ferrari does not have a fixed production cap.
The Lamborghini Revuelto, meanwhile, is currently available only as a coupe. Its latest addition to the range is the track-ready SV trim.
With its 1,064-horsepower hybrid powertrain, revised aerodynamics and 217-mph top speed, the Aston Martin Valhalla Spider adds an open-top option to the brand’s supercar lineup while maintaining the performance of the coupe.
