We've known for quite some time that the upcoming Aston Martin Valkyrie will have 1,000 horsepower from a naturally aspirated 6.5-liter V12. However, Aston Martin did not mention any other details about its hybrid-powertrain aside from the engine being built by Cosworth. This left most to speculate about other details regarding the engine and hybrid system.

Now just two years after the Valkyrie made its debut in Geneva 2017, Aston Martin has finally revealed the full details of the Valkyrie's hybrid-powertrain. The British marque says that the Valkryrie hypercar will have a total system output of 1,160 horsepower and 900 Nm of torque.

"Aston Martin Valkyrie is set to be the ultimate hypercar in the automotive world and these performance figures underline that statement. 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," said David King, vice president & special vehicle operations officer.

At the heart of the hypercar is a Cosworth built 6.5-liter V12 which can rev to 11,100 rpm and makes peak power at 10,500 rpm. The engine alone produces 1,000 horsepower and 740 Nm of torque, which is what Aston Martin mentioned before. Meanwhile, the KERS style hybrid system similar to those found in Formula 1 cars was developed by Rimac and Integral Powertrains. The full hybrid system contributes an additional 160 horsepower and 280 Nm of available torque when needed.

If you were ever curious how the engine sounds, Aston Martin has previously released a video showing how the V12 sings. The British automaker says that the V12 is said to take inspiration from high-revving F1 engines of the 90's, but combined with modern day material, technology and manufacturing expertise.

With Aston Martin still busy developing their Valkyrie hypercar, don't be surprised if other previous details such as weight and top speed change as well.
