Aston Martin has unveiled the Valhalla Spider, an open-top version of its mid-engine hypercar, with first customer deliveries scheduled for the third quarter of 2027, according to NetEase Auto.
The Spider is Aston Martin's first production supercar with an open-cockpit layout. It shares the hardtop Valhalla's plug-in hybrid (PHEV) powertrain, which combines a 4.0-liter twin-turbo V8 engine with three electric motors for a combined output of 1,079 hp and 1,100 Nm of torque. The V8 alone produces 828 hp, while the three motors and a high-performance battery add 251 hp.
Roof options and aerodynamics
The car comes standard with a removable black fabric soft top that can be stowed on board, allowing a top speed of 200 km/h with the roof closed. Customers can also opt for a carbon-fiber hardtop, which enables the electronically limited top speed of 350 km/h (217 mph). A rain cover is included for when the car is parked.
A dedicated wind deflector guides airflow over the open cockpit, directing cooling air into the revised top-mounted intake, which has been raised by 35 mm for the Spider. When the roof is closed, the deflector folds into three sections and stores in a new 15-liter sill compartment. The active aerodynamics and electronic stability program have been recalibrated to adapt to both roof-open and roof-closed driving conditions.
The Spider retains the signature carbon-fiber dihedral doors, now frameless and optimized for easier operation. New carbon-fiber touring seats come as standard for improved comfort and easier entry with the roof in place, while the hardtop's original carbon seats remain available at no extra cost.
Shared carbon-fiber architecture
The Spider is built on the same custom carbon-fiber monocoque as the hardtop Valhalla, developed by Aston Martin Performance Technologies using F1-derived resin transfer molding and autoclave techniques. Two electric motors drive the front axle with torque vectoring, while a third motor is integrated into the eight-speed dual-clutch transmission, sending power to the rear axle through an electronic limited-slip differential. There is no mechanical connection between the axles; an integrated vehicle dynamics control system continuously manages suspension, braking, steering, aerodynamics and powertrain. With the roof closed, maximum downforce exceeds 600 kg.
NetEase Auto reports that the Spider and hardtop differ only in the calibration of their active aerodynamics and stability systems, ensuring consistent performance whether the roof is open or closed.
