The first mid-engined open-cockpit Aston Martin keeps the Coupe's 1,079PS hybrid powertrain and makes its global debut in Las Vegas.
Aston Martin unveiled the Valhalla Spider on 28 October at Gaydon: an open-top version of its Valhalla hybrid supercar. It keeps the Coupe's 1,079PS and 1,100Nm drivetrain and, the company says, reaches 350km/h (217mph) without a roof fitted. Its global debut comes at the 2026 Concours at Wynn Las Vegas.
Aston Martin has taken the roof off the Valhalla. The Valhalla Spider, announced on 28 October from Gaydon, is the company's first mid-engined open-cockpit production supercar, and Aston says it can still reach its electronically limited 350km/h (217mph) top speed with the roof removed. That makes it the fastest open-cockpit car the marque has built.
The car is set to make its global debut at the 2026 Concours at Wynn Las Vegas.
Roof, wind deflector and seats
A black fabric roof that can be taken off and stowed comes as standard, with a rain cover supplied for when the car is parked. Fitted with the fabric top, the Spider is good for up to 124mph (200 km/h), which Aston describes as best in its class. An optional carbon fibre hard top removes that limit, giving roof-on access to the full 217mph.
With the roof off, a purpose-made wind deflector clips into place. Aston says it steers cooling air down to the snorkel while lifting the airstream over the occupants. The snorkel itself has been reprofiled for the Spider and sits 35mm taller than before. When the roof is on, the deflector folds into 3 parts and lives in new 15-litre storage apertures in the sills.
Inside, a new carbon fibre Touring Seat is standard and is meant to make getting in and out easier with the roof fitted. Buyers who want firmer support can keep the Coupe's original carbon seat at no cost. The carbon dihedral doors stay, now with revised kinematics, a frameless design and slightly more curvature on the top edge of the glass.
Same hybrid V8, same tub
Nothing changes under the skin. The Spider shares the Coupe's 1,079PS and 1,100Nm plug-in hybrid drivetrain, built around an 828PS 4.0-litre twin-turbo V8 with a flat plane crank. Aston puts its specific output at 207bhp-per-litre, the highest of any combustion engine it has made. Three electric motors and a high-performance battery add another 251PS.
Two of the motors drive the front axle and provide torque vectoring. The third sits alongside the 8-speed dual-clutch gearbox and helps the V8 drive the rear axle through an electronic differential. Because there is no mechanical link between front and rear axles, the company's Integrated Vehicle Dynamics Control system manages drive to each wheel, working with four driver-selectable modes.
The structure is a version of the Coupe's carbon fibre tub, engineered with Aston Martin Performance Technologies, the consulting arm of the Aston Martin Aramco Formula 1 Team. Its upper and lower sections are moulded using resin-transfer moulding and autoclave technology derived from F1.
Aerodynamics
The Spider carries the Coupe's full active aerodynamics, with moveable surfaces at both ends adjusting downforce and balance or cutting drag, depending on the mode selected. According to Aston, the only technical differences from the Coupe are revised active aero and stability control calibrations that adapt to airflow with the roof on or off. Maximum downforce is in excess of 600kg with the roof fitted.
Adrian Hallmark, Aston Martin's chief executive, said the Spider builds on the Coupe's list of firsts while keeping its looks and its dynamic range, adding the extra enjoyment of an open cockpit.
