If there’s a relative disappointment that supercar/hypercar aficionados and owners might point to, it’s the lack of ultra-high revs this powertrain produces with its redline set to 7,000 rpm. Then there’s the concert itself, a multifaceted mix of electric motors, turbos, induction, and exhaust. In totality, it’s loudish without being over the top, which is satisfying when your right foot opens the floodgates, but no one is ever going to include this on a list of best-sounding engines for the ages—there’s just a lot going on, and not for the audibly better.
Valhalla on the Track
There’s even more in play on the track, in this case Spain’s Circuito de Navarra, a 2.7-mile medium-speed road course with a nice blend of corners, braking zones, and some elevation change. This closed environment, much more so than the open road, reveals the power of the Aston Martin Valhalla’s trick torque vectoring, aerodynamics, and monster braking system.
You want to run the car in Race mode, not because it’s named as such and because you’re on a racetrack, but because of how the hybrid system operates. In Sport+ on the road, because drivers aren’t usually asking for full power in big long bursts, this mode dumps a huge amount of electric boost to the wheels, draining the battery at a quick rate that the brake-by-wire system then recovers so you’re ready to go again the next time.
However, on a track when you’re constantly pressing the throttle as quickly, hard, and often as possible, Race mode meters the electric assist via a recharge strategy that holds back up to 15 percent state of charge to protect you from ever running out and thus having to rely solely on the combustion engine. According to Kay, this results in a typical total loss of 15–20 hp, perhaps a maximum of 30, simply to prevent the battery from ever getting to zero charge. “In Sport+ on a track, you will get more noticeable reduced performance after a lap or two because it will start reining it in because it derates [the battery], but Race mode never does that—it’s overall the most efficient and usable,” he said.
That matches the firsthand experienced across a couple lapping sessions, and it’s beyond welcome to have a mode like this that takes care of everything for you so you can concentrate on driving the car without needing to fiddle around with buttons or contemplating the best driving strategy like F1 drivers are presently compelled to do.
As Angus reported after his previous drive, the Valhalla, for all its capability, feels as benign as a Vantage if you’re a reasonably experienced driver. The one thing he suspected but couldn’t confirm was if the car’s performance on the tighter Silverstone Stowe track would be the same on a faster, flowing circuit. But he was correct—the Valhalla takes whatever you throw at it and asks for more, thanks to its hugely stable platform that never feels like it’s about to drop-kick you off into the weeds.

What feels like mostly neutral handling, at least at the speeds I could summon during a first-drive press launch, is so rewarding that drivers looking for a big-drama circus filled with jarring traction breaks and huge sideways moments might want to look at cheaper, more conventional alternatives. For Aston slappies, consider the front-engine, rear-drive Vantage. Or save a lot of money and buy a BMW M car, or cheaper yet, a Mustang.
Sure, the Valhalla will dance sideways if you make it do so through a combination of snappy, aggressive throttle and weight-transferring steering inputs as you come off the brakes, but the front-axle torque vectoring and rear e-differential really just want to keep the chassis rotating into and pulling out of corners with minimal fuss, enticing the driver to push harder and harder while maintaining their confidence in the car. And that’s the entire point of all this whizbangery, given both the potential straight-line and cornering speeds. The double extra achievement Aston has pulled off is making all the dynamics-influencing tech feel entirely natural and virtually invisible to the driver.
To the point: When the lapping sessions were over, all I wished for was another hour or three on the track because I had just begun to feel like I knew both the circuit and car well enough to begin truly edging somewhere near at least approaching the limit. In other words, there was no feeling of relief over having managed to drive a million-dollar, 1,064-hp machine reasonably quickly around a racetrack without stuffing it into the fence. Once upon a time, driving cars as fast as this and others like it felt like a survival exercise as much as anything, but that’s no longer the case.
The active aero and braking system play huge roles in this. The latter gives you a beyond-satisfyingly firm brake pedal that never softens, thanks to a large amount of the actual braking being accomplished through battery regen. As with every brake-by-wire system I’ve so far encountered, the downside is a lack of granular feel compared to conventional hydraulic brakes; it’s not much of a deal when tuned well, it just feels different, especially if you expect to rely on old-school feedback to indicate when you’ve crossed the ABS threshold. You can forget about that, but more critically, the braking performance remains consistent, speed notwithstanding.
Aerodynamically, the underbody front wing and deployable monster rear wing adjust positions based on speed and dynamic conditions. Look under the car and you can see the former resembles an F1 front wing, and yes, Aston Martin Performance Technologies, a division of the F1 team, worked with the Valhalla’s engineers here. As for the rear wing, it also provides an air-brake function when you stomp on the left pedal. In general, it only raises fully in Race mode, and while you can activate that mode on the street, know it entirely blocks the rearview camera, meaning you have no idea what’s behind you.
(Note to cars and coffee peacockers: In a bit of nonsensical bureaucracy, you can’t raise the rear wing with the car turned off, thanks to silly-worded crash regulations intended to prevent its use on the street. Aston may or may not be searching for a workaround following feedback from nearly “everyone who has been around the car.” Also note: The engine cover, due to needing a particular fit to maintain aero performance, requires manual removal with the assistance of simple tools, so you probably won’t be seeing the V-8 on open display, either. Tragic.)
