Aston Martin has revealed details of the engine at the heart of its Valkyrie hypercar.
The naturally-aspirated V12, developed in conjunction with Cosworth, uses "F1 knowledge" to reach a maximum output of 746kW (1000bhp). The engine can rev to a stratospheric maximum of 11,100rpm with peak torque (740Nm) arriving at 7000rpm.
Despite those specifications, the 6.5-litre V12 engine still passes the stringent emissions regulations that have forced many competitors to implement turbochargers.
Cosworth’s F1 knowledge spreads to the construction of the engine itself, with titanium conrods and pistons that are built to F1TM-spec. The crankshaft is billet-machined and takes six months to manufacture.
The engine weighs in at just 206kg and is a structural ‘fully-stressed’ component of the vehicle. Aston Martin says with the engine removed there is nothing that connects the front wheels to the rear ones.
While the brand has not needed to turbocharge the Valkyrie, the engine is supplemented by a battery-hybrid system, the details of which are yet to be announced.
The engine is a 'fully stressed' load-bearing part of the wild-looking Valkyrie's structure.
The AMG One is set to be powered by a totally different (but also F1-derived) 1.6-litre V6 turbocharged petrol engine, assisted by four electric motors, while the Speedtail will be powered by a twin-turbo V8 producing 772kW (1035hp).
The Valkyrie's stripped-back interior also features an F1-inspired steering wheel.
All three cars wish to claim the title of the ultimate road-going hypercar, so should re-set the bar for road-going performance and technology in the coming years.
