The 2025 Aston Martin Valhalla: A Hypercar That Rewrites the Rules of Performance
A Modern Rocket Ship That Defies Expectations
“So, how was it?”
It’s the inevitable question everyone asks when you’ve just spent time behind the wheel of a machine like the 2025 Aston Martin Valhalla. At nearly $1.1 million and producing 1,064 horsepower, it’s a car that blurs the line between supercar and hypercar, a high-tech masterpiece that leaves you questioning the very definition of performance.
When friends and colleagues asked me about my experience, I briefly hesitated before answering, “It’s exactly what you expect,” a phrase that might sound dismissive until you realize the extraordinary context of the 2020s automotive landscape. Today’s supercars are so advanced that they operate on a different plane of existence, something most people can only imagine until they experience it firsthand.
A Long Time Coming
It feels like a lifetime ago that Aston Martin first unveiled the AM-RB 003 concept at the 2019 Geneva Motor Show. Back then, the name reflected Aston’s ties to the Red Bull Racing Formula 1 team, but much has changed since then. The automotive world has evolved rapidly, and Aston has undergone significant transformation.
The automotive landscape has shifted dramatically, and Aston is at the forefront of this evolution. We’ve seen chaotic changes in internal ranks, and the Valhalla’s powertrain has transformed. Initially planned as an in-house turbocharged V-6, it has evolved into a hybridized twin-turbo V-8 derived from the Mercedes-AMG GT Black Series. This engine has been further enhanced by Aston Martin with larger turbos, a new intake manifold, and stronger pistons, pushing the output well beyond the AMG’s 720 hp.
When I sat in the prototype at the 2022 Pebble Beach Concours, the projected specs for the V-8-based powertrain had jumped from a combined 937 horsepower and 738 lb-ft of torque to 1,012 hp. While Aston stated that these figures were not final, I was ready for whatever they had in store. I knew this car was worth the wait, no matter how long it took.
Worth the Wait…
Based on Aston Martin’s initial timeline, I didn’t expect another three and a half years to pass before I got to drive the Valhalla. However, the production version’s hardware exceeds all those earlier expectations.
The flat-plane-crank, dry-sump, twin-turbo 4.0-liter V-8 makes a staggering 817 hp. Combined with 248 hp from three Aston-designed radial-flux permanent-magnet motors, the Valhalla produces a total output of 1,064 hp and 811 lb-ft of torque. The electric motors, one on the front axle and another mounted to the new eight-speed dual-clutch gearbox (a first for Aston), power the car independently or in tandem with the combustion engine.
This new hybrid system is powered by a 560-cell battery pack, kept cool by immersion in dielectric oil. This innovative cooling method allows for rapid charging and deployment of electrical energy, making the Valhalla suitable for high-performance track use. Unlike the original concept and its Valkyrie stablemate, the production model is a plug-in hybrid, capable of achieving up to 80 mph in EV mode and covering approximately 8.7 miles on electric power alone.

…But Something Else Happened Along the Way
Supercar enthusiasts may quibble over the distinction, but Aston Martin officially refers to the Valhalla as its first-ever mid-engine supercar. However, given the existence of the Valkyrie, Aston is restricted to using “supercar” when discussing their milestone achievements. While this might seem contradictory, the Valkyrie is barely a street-legal vehicle. Its starting price of over $3 million and limited production of 285 units make the Valhalla’s $1 million-plus price tag and 999-unit production run seem relatively pedestrian in comparison.
This absurd comparison speaks to a larger reality in modern high-performance automobiles—both in terms of price and capability.
For enthusiasts in their 20s and 30s, the constant barrage of new million-dollar cars in their social media feeds is nothing new. Each new model delivers unheard-of power and torque figures, blisteringly fast acceleration and lap times, and a feature list that stretches longer than the Nürburgring’s full endurance layout.
However, for those of us who remember the shockwave created by the 627-hp McLaren F1 in 1994 or the Bugatti Veyron just 20 years ago—the car widely regarded as the first million-dollar, 1,000-hp hypercar—today’s automotive landscape feels surreal.
Since I first saw the Valhalla prototype at Pebble Beach, we’ve tested cars like the Porsche 911 GT3 RS, which has roughly half the horsepower but brings so much racing-derived technology that it requires professional driving skills to maximize on a track. Its suitability as a road car is debatable, given its stiff suspension setup.
Stepping up in price, construction, and technological prowess, we have the Ferrari F80, 849 Testarossa, and Czinger 21C VMax, just to name a few recent models we’ve tested. You can even buy a hybrid Corvette ZR1X with 1,250 hp, a car that no one saw coming when the Valhalla was first conceived by Aston Martin and their then-partner, Adrian Newey.
Just Drive It
When you consider the insane performance levels of these machines, the saying “comparison is the thief of joy” has never been more apt. It’s also fitting here because we know the odds of orchestrating a proper comparison test among the vehicles listed above are virtually zero. Ferrari, for one, rarely supplies their cars for head-to-head showdowns. (A shame, Ferrari.)
No matter. Given the extreme dynamic limits of these cars, it’s far more satisfying to drive something like the Valhalla on its own merits and appreciate the unique experience it offers.
On the Road
The overall experience is crucial in a car like this. For quite some time, it hasn’t been enough for a car to be fast and thrilling on the road if it handles like garbage on the track, or vice versa. Angus MacKenzie’s earlier review of the Valhalla confirmed that this car excels on both fronts.
Unlike Angus, who only drove it on the Silverstone Circuit, Aston gave us a 50-minute road loop to start. You might expect a car with a Le Mans Hypercar appearance and a low, wide stance to be uncomfortable on public roads, but that’s not the case. The only real drawback is the lack of luggage storage; there are some small cubbies in the door cards, but no frunk, as that space is occupied by three radiators and the suspension system.
Aston implemented this pushrod-actuated inboard suspension to accommodate the F1-style seating position. Since you sit so low, a conventional suspension would have raised the roofline too much to maintain clear visibility. There’s no backrest angle adjustment, so you must adapt to the seating position. The seats are bolted low into the carbon-fiber tub, with no motors for vertical adjustment. Instead, you pull a leather strap to slide the seat forward or back.
You quickly get used to the driving position, which isn’t as extreme as it seems. Within a few miles, you realize the Valhalla’s Bilstein DTX active damper system and overall suspension setup (the rear uses a five-link layout) make for a comfortable ride. The Spanish road we drove wasn’t perfectly smooth, but it wasn’t a deathtrap of potholes either. The gap between the suspension’s Sport and Sport+ settings is small—a welcome feature we’ve praised in other Aston models like the Vantage. Race mode introduces a harsher ride you’d likely tire of in normal driving, but it’s manageable, especially on a well-maintained fast road when it’s time to play.
A Surprise in the Sound
The flat-plane-crank V-8 redlines at 7,000 rpm, and the combined exhaust note is a symphony of electric motors, turbos, induction, and exhaust. It’s loud enough to be satisfying when you open the throttle, but no one will ever include this on a list of best-sounding engines. There’s just a lot going on, and not necessarily for the better.
Valhalla on the Track
The real magic happens on the track. At Spain’s Circuito de Navarra, a 2.7-mile road course with a mix of corners and elevation changes, the Valhalla’s torque vectoring, aerodynamics, and braking system shine.
You’ll want to use Race mode, not just because it’s called Race mode, but because of how the hybrid system operates. In Sport+ mode, because drivers typically don’t ask for full power in long bursts, this mode dumps a huge amount of electric boost to the wheels, draining the battery quickly. The brake-by-wire system then recovers the energy, ensuring you’re ready for the next burst.
However, on a track when you’re constantly pressing the
