Aston Martin's Valhalla Spider Drops the Roof, Keeps the 1,079PS Hybrid Punch

Aston Martin has pulled the wraps off the Valhalla Spider, a roof-off take on its mid-engined plug-in hybrid supercar — and yes, it still hits the electronically capped 350 km/h (217 mph) with the lid removed. Customer deliveries are penciled in for Q3 2027, following a public debut at the Concours at Wynn Las Vegas this weekend.

The British marque bills it as its quickest open-cockpit car to date, and the first series-production mid-engined Aston with a removable roof. Compared with the Valhalla Coupe that landed earlier this year, engineers changed surprisingly little: recalibrated active aero and stability control are the headline tweaks, and peak downforce stays above 600 kg when the roof is on.

Roof Choices Come With a Catch

There’s a fine print worth reading before you spec one:

• Standard fabric roof (outside the US): speed capped at 200 km/h (124 mph)
• Carbon fibre hard top (standard in the US): unlocks the full 350 km/h
• Cockpit airflow: handled by a clip-in wind deflector
• Air snorkel: repositioned 35 mm higher than the Coupe

The powertrain is untouched. An 828PS twin-turbo 4.0-litre flat-plane-crank V8 works alongside three electric motors contributing 251PS, for a combined 1,079PS and 1,100 Nm. Two of those motors sit on the front axle and handle torque vectoring. Aston Martin quotes a 0-100 km/h sprint of 2.5 seconds.

Key Specs: 1,079PS combined · 1,100 Nm · 350 km/h top speed (roof off) · 0-100 km/h in 2.5s · Deliveries from Q3 2027

The carbon fibre tub, developed by Aston Martin Performance Technologies — the consulting arm of the company’s Formula One operation — carries over, which is precisely why the engineering bill stayed low.

Why the Spider Matters More Than It Looks

Aston Martin has pushed back its first battery-electric model more than once, citing soft demand at the luxury end. Until that changes, high-performance plug-in hybrids like the Valhalla are doing the heavy lifting on electrification. Small-volume derogations baked into EU and UK CO2 rules make that route viable for a low-output manufacturer.

There’s a commercial angle too. By limiting the Spider to aero and stability recalibration, Aston Martin turns the Coupe’s development spend into a second revenue stream at minimal extra cost. Choosing Las Vegas for the reveal says plenty about where the buyers are — the US remains central even with tariffs weighing on UK-built exports.

And the F1 connection is quietly becoming a business in its own right. Having AMPT engineer the tub and chassis dynamics shows the race team functioning as an in-house consultancy, with the potential to take on outside clients down the line.

Adrian Hallmark, Aston Martin’s chief executive, framed the Spider as preserving the Coupe’s looks and dynamic breadth while adding something only an open cockpit can deliver. First deliveries arrive in the third quarter of 2027.
