Aston Martin has revealed the Valhalla Spider, which the brand claims is its fastest open-top car yet. It can hit its 350kph top speed even with the roof off and shares its 1,079hp plug-in hybrid powertrain with the Valhalla Coupe. The Valhalla Spider will make its global debut at the Concours at Wynn Las Vegas, which will run from October 29 to November 1, 2026. Meanwhile, global deliveries are set to begin in the third quarter of 2027.
- Removable fabric roof standard in most markets; carbon-fibre hard-top optional.
- Carbon-fibre tub by Aston’s F1 consulting arm, plus active aero and carbon-ceramic brakes.
- 0-100kph in a claimed 2.5 seconds; over 600kg of downforce with the roof fitted.
Aston Martin Valhalla Spider design
Removable fabric roof, active aerodynamics and a carbon-fibre tub
The Valhalla Spider comes with a removable black fabric roof as standard, while a carbon-fibre hard-top is optional. In the US, however, the latter comes as standard fitment. With the fabric roof on, the Spider is limited to 200kph, while the hard-top allows it to reach its claimed top speed.
To manage airflow with the roof off, the Valhalla Spider gets a wind deflector that clips into place once the roof is removed. Aston Martin says it directs air down to the roof-mounted scoop while lifting it over the occupants. With the roof on, the deflector folds into three parts and fits inside new 15-litre storage compartments in the sills. The scoop itself has been reprofiled for the Spider and sits 35mm higher than on the Coupe.
The carbon-fibre dihedral doors have been carried over from the Coupe but are now frameless. Aston Martin claims that these also open more smoothly. The door glass also has a slightly more curved top edge, which should make ingress and egress easier with the roof on. The Valhalla Spider gets active aerodynamics too, including a rear wing that rises by 255mm in ‘Race’ mode and a concealed wing up front. These and the stability programme have been recalibrated for roof-on and roof-off driving, while Aston Martin also claims that the Valhalla Spider produces over 600kg of downforce with the roof fitted.
Underpinning the Valhalla Spider is a carbon-fibre tub that’s been designed and engineered by Aston Martin Performance Technologies, which is the consulting arm of Aston’s F1 team. The tub’s upper and lower sections are moulded from carbon fibre using a combination of resin transfer moulding and autoclave technology derived from F1, the brand says. This is paired with aluminium front & rear subframes, pushrod double-wishbone front suspension and adaptive Bilstein dampers. Carbon-ceramic brakes are standard, featuring 410mm discs at the front and 390mm discs at the rear.
As for its dimensions, the Aston Martin Valhalla Spider measures 4,728mm long, 2,208mm wide (ORVMs included) and 1,233mm tall – the wheelbase is 2,760mm. The supercar rides on 20-inch forged wheels at the front and 21-inch units at the rear that are wrapped in bespoke Michelin Pilot Sport S 5 tyres. Buyers can personalise the Valhalla Spider with tinted carbon-fibre finishes in red, green or blue. There will also be 10 liveries to choose from, five of which are offered only with the hard-top version.
Aston Martin Valhalla Spider powertrain and performance
An 828hp twin-turbo V8 is paired with three electric motors
The Aston Martin Valhalla Spider is equipped with the same plug-in hybrid powertrain as the Coupe. The combustion portion of this is made up of a 4.0-litre flat-plane-crank twin-turbo V8 that develops 828hp and 868Nm on its own. This mill’s specific output of 207hp per litre is the highest of any combustion engine produced by Aston Martin to date, the brand says.
The electric portion of the equation comes from the three electric motors and a 6.1kWh battery pack, adding another 251hp to the mix. This takes the combined output up to 1,079hp and 1,100Nm. Two motors sit on the front axle and provide electric torque vectoring. The third motor is integrated into the 8-speed dual-clutch automatic gearbox and works with the V8 to drive the rear wheels via an electronic limited-slip differential.
According to Aston Martin, there’s no mechanical link between the front & rear axles, with the power to each wheel being managed by the ‘Integrated Vehicle Dynamics Control’ system. The automatic transmission doesn’t come with a reverse gear either, as this function is handled by the electric motors at the front.
Aston Martin says that the predicted 0-100kph time for the Valhalla Spider is 2.5 seconds, while the electronically limited top speed is a claimed 350kph. The Valhalla Spider weighs 1,680kg (dry and with lightweight options) and gets four drive modes: Sport, Sport+, Race and EV.
Aston Martin Valhalla Spider interior and features
Gets carbon-fibre ‘Touring’ seats, dual-digital displays and an optional Bowers & Wilkins audio system
Inside, the Valhalla Spider comes with carbon-fibre ‘Touring’ seats as standard. Aston Martin says that these are more comfortable and also make ingress and egress easier with the roof on. Buyers who prefer more support can opt for the Coupe’s carbon-fibre units instead at no extra cost. This interior also gets knurled metal and weaved carbon-fibre trim.
Aston Martin’s bespoke Q division offers further personalisation, with tinted carbon-fibre finishes in Podium Green, Teal and Bronze. Also available are custom liveries and individual combinations of interior materials. The cabin features a 10.25-inch digital driver’s display and a 10.25-inch touch-infotainment system with Apple CarPlay, along with a digital rear-view mirror and Alcantara trim.
The Valhalla Spider can be had with a Bowers & Wilkins audio system as an optional extra. Some of the safety tech includes autonomous emergency braking, adaptive cruise control with ‘stop & go’ functionality, lane-keeping assist and driver monitoring.
