Road and Track cites "sources deeply familiar with the car", claiming the Valkyrie will have a total output of around 840kW from its Formula One-inspired hybrid drivetrain, with nearly 1000hp (745kW) alone coming from the 6.5-litre naturally-aspirated V12 co-developed with British tuning firm Cosworth.
With that in mind, the company will have achieved, or perhaps exceeded (if those figures are accurate) its goal of one horsepower for every kilogram of weight.
Numerous weight-saving and aerodynamic technologies have been employed to make the Valkyrie as light and slippery through the air as possible. Road and Track reports that the hypercar will not have exterior mirrors, instead opting for a camera system with LCD displays on each side of the dashboard.
Even the iconic winged metal Aston Martin logo on the nose has gone on a strict diet, reportedly measuring a micron thick and weighing a few milligrams.
The publication adds the minimalist approach has extended to the interior as well, with the console allegedly measuring less than three inches (76mm) wide, and just about every vehicle control positioned on the steering wheel.
We already know the Valkyrie's battery system will be sourced from Rimac - the company behind the manic Concept One electric supercar - while the carbon braking system will be supplied by Alcon and Surface Transforms.
German tech powerhouse Bosch has also been confirmed to provide various technology elements, though exactly what that involves is unclear at this point.
Only 150 examples of the Valkyrie will be produced in road-going guise, including prototypes. The company has also confirmed an additional 25 'track-only' versions will be built.
Road and Track's source says each vehicle will be tailored to its owner, with a custom driver's seat based on a three-dimensional body scan of the owner to feature.
It's also reported that Aston Martin wants to race the Valkyrie in the Le Mans endurance race next year, which would make sense considering the vehicle basically looks like a road-going LMP1 race car as it is.
