Aston Martin says the Valhalla Spider reaches a top speed of 217 mph with its removable soft top stowed, while a sensor limits it to 124 mph with the top fitted. The plug-in-hybrid supercar is due to debut at the 2026 Concours at Wynn Las Vegas; pricing has not been announced.

Aston Martin says its 1,064-horsepower Valhalla Spider can reach 217 mph with the soft top removed, but is electronically limited to 124 mph when the roof is fitted. The convertible version of the plug-in-hybrid supercar is set to debut at the 2026 Concours at Wynn Las Vegas; the company has not yet announced its price.

The Spider shares its core powertrain with the Valhalla coupe: a 4.0-liter twin-turbo flat-plane V8, three electric motors and a 6.1-kWh battery. Aston Martin lists output at 1,064 horsepower and torque at 811 lb-ft. The company says the car can accelerate from 0 to 60 mph in 2.5 seconds and has an electric-only range of 8.7 miles.

The roof-speed difference is the standout specification. According to the report by The Drive, Aston Martin gives the Spider a 217-mph top speed with the roof off and a 124-mph limit with the soft top in place. A sensor detects whether the roof is fitted and prevents the car from exceeding that lower limit. The source does not explain the engineering reasons behind the difference.

The standard roof is a removable soft top that can be rolled up and stored in the car. Aston Martin also offers a carbon-fiber hardtop, but it cannot be stowed in the vehicle, according to The Drive. The Spider has revised aerodynamics and electronic adjustments, which the company says preserve a dynamic driving experience. It also gets a folding wind deflector that stores in sill compartments and touring seats as standard; carbon-fiber bucket seats remain available at no extra cost.

The developmentAston Martin has announced Valhalla Spider performance and roof details ahead of its planned debut at the 2026 Concours at Wynn Las Vegas.

A Convertible With a Roof-On Speed Limit

The Spider’s figures make roof configuration more than a comfort or styling choice: it changes the car’s stated maximum speed by 93 mph. That is relevant to prospective buyers comparing the Spider with the coupe, as well as to drivers deciding whether to use the soft top at high speeds. Aston Martin’s sensor-based limit means the roof-on figure is an enforced cap, not simply a separate estimate of performance.

The open-top version also combines supercar performance with a removable roof and features aimed at longer or more everyday drives, including touring seats and a stowable wind deflector. Those details suggest Aston Martin is positioning the Spider as more than a track-focused specification, although the source does not provide independent testing or comparisons with rival cars. With pricing still unknown, buyers cannot yet assess how much the convertible configuration will cost relative to the coupe.

How the Spider Relates to the Coupe

The Valhalla is Aston Martin’s plug-in-hybrid supercar, built around a twin-turbocharged V8 supported by three electric motors. The Spider retains the coupe’s basic powertrain and headline output, while adding an open-roof option. Aston Martin lists 8.7 miles of electric-only range and a 6.1-kWh battery; those figures are provided as specifications, not as independent test results.

The coupe’s starting price is reported at $1,051,700. Aston Martin has not released Spider pricing, so that coupe figure provides a reference point rather than a confirmed price for the convertible. The Spider is scheduled to make its public debut at the 2026 Concours at Wynn Las Vegas, according to the source report.

“The Spider’s top speed is 217 mph with the roof off and 124 mph with the soft top on.”

Pricing and Speed-Claim Details Pending

Spider pricing has not been announced, and the source does not specify when Aston Martin will begin deliveries or how many cars it plans to build. Although Aston Martin’s stated roof-off speed is 217 mph, the report does not describe the test conditions or provide independent verification of that claim.

The reason the stated maximum speed falls to 124 mph with the soft top fitted is also not explained. Aston Martin says a sensor enforces the limit, but the available information does not identify the aerodynamic, structural or other considerations behind it. The source likewise does not give a separate top-speed figure for the optional carbon-fiber hardtop.

Debut Before Pricing Details

The next stated milestone is the Valhalla Spider’s debut at the 2026 Concours at Wynn Las Vegas. Aston Martin has not provided a date for pricing announcements, ordering or customer deliveries in the source material. Further company details may clarify the Spider’s cost, production plans, roof options and the basis for its published performance figures.
