Aston locks in Valkyrie’s 865kW/900Nm powertrain
BY TUNG NGUYEN | 4th Mar 2019
ASTON Martin’s upcoming Valkyrie hybrid hypercar will use electrification to boost the performance of its 6.5-litre naturally aspirated V12 engine to 865kW of power at 10,500rpm and 900Nm of torque at 6000rpm.
Taking on the likes of the Mercedes-AMG Project One, the Aston Martin wins out in the power department as the German hypercar features “more than 740kW”, while torque numbers are still secret.
Redlining at a stratospheric 11,100rpm, the powerplant of the Valkyrie combines a bespoke Cosworth-built 6.5-litre V12 petrol engine confirmed last year to produce 747kW and 740Nm, while a battery system from Rimac adds 119kW/280Nm.
Full details including the Valkyrie’s 0-100km/h acceleration time are yet to be revealed, but, with numbers eclipsing Ferrari’s 812 Superfast and a Lamborghini Aventador S, expect to see a sub-3.0-second time.
Little else is currently known about the Valkyrie, but the British sports-luxury brand is saying the engine and gearbox casing will also serve double duty as stressed members of the vehicle structure, eliminating the need for an additional rear subframe.
A Formula One-inspired kinetic energy recovery system (KERS) will also feature in the Valkyrie, which can be used to boost performance even further.
Aston Martin vice-president and special vehicle operations officer David King said Valkyrie is positioned to deliver awesome performance and yet still meet emissions regulations.
“Aston Martin Valkyrie is set to be the ultimate hypercar in the automotive world and these performance figures underline that statement,” he said.
“Red Bull Advanced Technologies, Cosworth, Rimac and Integral Powertrain LTD have been fantastic partners in the development of this powertrain, ensuring that we have already created a hybrid system that is emissions-compliant and ready to begin fitting to our first physical prototypes.”
