Aston Martin Valhalla Spider Debuts in Las Vegas With 1,064 HP and 217 MPH, Roof Off

Aston Martin has taken the roof off its first mid-engine production car, and the open version gives up almost nothing to the coupe. The Valhalla Spider keeps the same 1,064-hp (1,079 PS) plug-in hybrid powertrain and, according to the company, still reaches its electronically limited 217 mph (350 km/h) with the roof removed.

That makes it, by Aston Martin's account, the fastest open-cockpit car the brand has built. The car goes on public display this weekend at the Concours at Wynn Las Vegas, which runs October 29 through November 1, which makes the US the site of its public debut. It builds on the Valhalla coupe, which already has a Breitling program reserved for its 999 owners.

Same hardware, different roof

Under the skin, little has changed. A 4.0-liter twin-turbo V8 with a flat-plane crank makes 817 hp (828 PS) on its own, and three electric motors add another 248 hp (251 PS). Combined torque is 811 lb-ft (1,100 Nm), sent through an eight-speed dual-clutch gearbox. Two of the motors drive the front axle with torque vectoring; the third sits with the transmission and helps power the rear wheels.

Aston Martin says the engineering differences between the two body styles are limited to new active-aero and stability-control calibrations. With the roof fitted, the Spider still generates more than 600 kg (1,323 pounds) of downforce, the same figure the company quotes for the coupe.

The roof setup is where buyers will have to choose. The standard black fabric panel comes off and stows, but it limits the car to 124 mph (200 km/h). An optional carbon-fiber hardtop removes that cap. With nothing overhead, a clip-in wind deflector manages airflow over the cabin and folds into three pieces that fit in new 15-liter storage bins in the sills. A rain cover is supplied for when the car is parked.

Other changes are small but practical. The carbon dihedral doors are now frameless, a new carbon Touring Seat is standard, and the coupe's more aggressive seat remains available at no cost. CEO Adrian Hallmark summed up the brief in four words: "Roof on or roof off."

How it stacks up

The Valhalla Spider lands in a small group of hybrid roadsters with four-figure outputs. Ferrari's SF90 Spider, its closest rival on paper, makes 986 hp (1,000 cv) and uses a retractable aluminum hardtop that opens in 14 seconds, even on the move. The Aston sticks with removable panels instead.

McLaren's 750S Spider plays a tier below: 740 hp, a claimed 206 mph, and a launch price of $345,000 before fees, Motor1 reported in 2023. It is also on its way out, with McLaren ending 750S production in 2027, just as Spider deliveries begin.

What US buyers still don't know

Aston Martin says deliveries start in the third quarter of 2027. It hasn't said when US customers will get cars, what the Spider costs, how many will be built, or how much it weighs. It also hasn't published acceleration figures for the open car. For reference, the Valhalla coupe is reported to cost about $1 million and is capped at 999 units.

US pricing is the next number to watch. The Valhalla is one of several new products from the brand this fall, alongside the DBX GT.
