Aston Martin has taken its already outrageous Valhalla hybrid hypercar and made it even more desirable by removing the roof. The new 2028 Aston Martin Valhalla Spider brings open-air excitement to the British automaker’s mid-engine masterpiece without sacrificing the breathtaking performance of its fixed-roof counterpart. With 1,064 horsepower, advanced Formula 1-inspired aerodynamics, and a top speed of 217 mph, the Valhalla Spider becomes the fastest open-cockpit Aston Martin ever produced. It’s an impressive achievement considering how much engineering typically goes into keeping a hypercar stable and aerodynamic after its roof has been removed.

Underneath the striking bodywork, the Valhalla Spider retains the same sophisticated plug-in hybrid powertrain found in the coupe. A twin-turbocharged 4.0-liter flat-plane-crank V8 works alongside three electric motors to produce a combined 1,064 horsepower and 811 lb-ft of torque. An eight-speed dual-clutch transmission manages the power, while two electric motors drive the front wheels and a third assists the gasoline engine at the rear. The result is an advanced all-wheel-drive setup capable of launching the Valhalla from 0 to 60 mph in approximately 2.5 seconds. More importantly, the Spider preserves the coupe’s remarkable 217-mph maximum speed, even when driving with nothing but open sky above the occupants.

One of the more interesting aspects of the Valhalla Spider is its choice of roof configurations. Aston Martin includes a removable fabric roof as standard equipment, which can be conveniently stored inside the vehicle when not in use. However, there’s an unusual catch. With the fabric roof installed, the car’s maximum speed is limited to 124 mph. Buyers who want to enjoy the full 217-mph capability with a roof overhead can opt for the removable carbon fiber hardtop instead. The hardtop offers greater aerodynamic stability at extreme speeds, although it doesn’t provide the same onboard storage convenience as the fabric roof.

Making an open-top hypercar capable of reaching 217 mph required much more than simply cutting away the roof. Aston Martin worked with engineering expertise developed through its Formula 1 program to redesign airflow around the cockpit and rear-mounted engine intake. A specially designed wind deflector helps channel air over the occupants and toward the intake snorkel behind the seats, ensuring the V8 receives sufficient airflow even at high speeds. The automaker also recalibrated the active aerodynamic system and electronic stability controls to compensate for the different airflow characteristics when the roof is removed. These changes allow the Spider to maintain impressive high-speed stability without dramatically compromising its performance.

Another clever detail involves the storage compartments integrated into the Valhalla Spider’s side sills. Each side features dedicated storage space, allowing the fabric roof and folding wind deflector to be tucked away without taking up valuable cabin room. Aston Martin also preserves the lightweight carbon fiber construction that makes the Valhalla such a technologically impressive machine. The Spider shares much of its structural architecture with the coupe, helping maintain rigidity despite losing the fixed roof. Combined with its sophisticated suspension and active aerodynamic technology, the open-air Valhalla promises to deliver the same precise handling characteristics that define the coupe.

Of course, the Valhalla Spider isn’t simply about setting records or producing outrageous performance figures. There’s something particularly appealing about experiencing the sound of a high-revving, twin-turbocharged V8 without a roof separating occupants from the engine’s soundtrack. Aston Martin has also maintained the Valhalla’s dramatic styling, including its low-slung proportions, aggressive aerodynamic elements, and unmistakable hypercar presence. The roofless configuration adds another dimension to the driving experience, especially for buyers who appreciate the mechanical sounds and sensations that increasingly sophisticated performance cars sometimes manage to isolate from their drivers.

Aston Martin hasn’t officially announced pricing for the Valhalla Spider, although it’s expected to carry a substantial premium over the coupe, which starts at approximately $1,051,700. Deliveries are expected to begin during the third quarter of 2027, making this a highly exclusive addition to an already limited-production hypercar family. Considering the growing demand for open-top versions of the world’s most exotic performance cars, we wouldn’t be surprised to see wealthy collectors lining up for the opportunity to own one. The Valhalla was already an extraordinary achievement for Aston Martin, but the Spider might be the version we’d choose if money were no object. After all, experiencing more than 1,000 horsepower with the roof removed sounds like the kind of automotive indulgence that makes a million-dollar hypercar feel truly special.
