With Valkyrie’s first prototypes beginning to take shape, Aston Martin has finally decided to release the specs of its F1 inspired hybrid powertrain. The Valkyrie boasts a maximum output of 1,176 hp and peak torque of 664 lb-ft.
The heart of the Aston Martin Valkyrie’s powertrain is a Cosworth built naturally aspirated 6.5-litre V12. According to Aston, the Valkyrie’s V12 is inspired by the ultra-high-revving F1 engines of the 1990s, but benefits from progress in design, material and manufacturing expertise made over the following decades. Of the total power figure, the V12 alone delivers 1,013 hp and 546 lb-ft of torque. The engine can rev to a stupendous 11,100 rpm and produces peak power at 10,500 rpm. Another 162 hp and 207 lb-ft comes from the battery-electric system that is intended to provide KERS-style boost like in F1 cars. The hybrid system has been developed by two main technical partners. The electric motor has been supplied by Integral Powertrain Ltd whereas Rimac is responsible for the battery pack.
“Aston Martin Valkyrie is set to be the ultimate hypercar in the automotive world and these performance figures underline that statement” Aston Martin Vice President & Special Vehicle Operations Officer, David King 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. I am, as I’m sure the rest of the world is, incredibly excited to see and hear the first of these cars on track”.
In addition to the powertrain figures, Aston has detailed additional credentials of the Valkyrie’s engineering in the release. Unlike traditional supercars, the Valkyrie’s main components have been designed to perform more than one role. For example, both the V12 engine and gearbox casing act as stressed members of the vehicle structure. The latter provides rear suspension mounting points, while also helping provide even greater structural rigidity and eliminating the weight of an additional rear subframe. Meanwhile, the Valkyrie’s battery pack also serves as the carrier for the vehicle’s power electronics whereas the E-Motor is designed to aid mechanical performance of the gearbox, in addition to its power boost and energy recovery system functions.
As it’s already evident, the Aston Martin Valkyrie stands to be one of the greatest, most anticipated supercars of this decade and we can’t wait to see it on the roads. But, we won’t have to wait too long as first deliveries of the hypercar start later this year.
