Aston Martin has confirmed its Valkyrie hypercar produced 1000hp on the dyno. The dizzying output is courtesy of a Cosworth-developed 6.5-litre naturally aspirated V12 that delivers its peak power at 10,500 RPM.
Cosworth MD Bruce Wood confirmed the 1000hp target was agreed well before the first prototype was built. The V12 also serves as a structural component. Just like a race car, the motor will be bolted directly to the Valkyrie’s tub and have the transmission and suspension hung from it.
The engine uses port fuel injection instead of direct injection, allowing it to meet emissions norms without having to resort to gasoline particulate filters. The engine weighs just 204kg in road-ready trim and has been designed to last at least 100,000km based on routine maintenance.
You are looking at an exquisite design hiding the most powerful road-legal V12 in the world.
An electric motor will augment the engine, sitting between it and a single-clutch, seven-speed gearbox designed by Ricardo. The electric motor uses Formula One-inspired KERS, recovering energy under braking. Cosworth briefly tweeted the technical details of the engine, removing the tweet shortly afterwards. The projected power figures catapult the exquisite Valkyrie ahead of the Mercedes-AMG Project One as well as the McLaren Senna. Only the McLaren Speedtail can perhaps come close to the British hyper-hybrid.
Rimac is supplying Aston Martin lightweight hybrid batteries. Cosworth suggested that the total hybrid output of the Valkyrie would exceed 1,130hp. A laundry list of illustrated partners have come together in the making of the car. Apart from Cosworth, Rimac and Ricardo, other partners include Multimatic (carbon fibre chassis tub), Red Bull Advanced Technologies (Formula One technology), Bosch (electronics), Alcon and Surface Transform (brakes), Wipac (lighting), and Michelin (tyres).
The Valkyrie is the fruit of the collaboration of the automotive industry's leading names like Bosch, Rimac, Red Bull Racing, and so on.
Red Bull Racing CTO Adrian Newsey talked about the partners, “Much like in Formula 1, designing, engineering and building a car like the Valkyrie is a massive team effort. To achieve great things you need to surround yourself with the best people.
“Experience, creativity, energy, diligence and perfectionism are absolute must-have qualities in every area of the project. Having great technical partners such as those working with us is both reassuring and motivating. Together, we aim to produce an innovative piece of engineering art.”
Vice President of Aston Martin, David King said: “Making the Valkyrie presents huge challenges. It’s a real test of everyone involved, but that’s as it should be, for we’re genuinely raising the bar with this car. That’s what makes the project so special, and why having the right technical partners is so critical.
“Some of those names we’re working with are long-standing suppliers of Aston Martin, but there are some new names in there, too. Whether forging fresh partnerships or building on existing relationships, this project is a shared engineering adventure that we’re all relishing.”
