A High-Revving Powerhouse
The Aston Martin Valkyrie final horsepower and torque numbers are in. The hybrid powertrain in the car features a Cosworth-built 65-degree naturally aspirated 6.5-liter V12 paired with a Rimac-sourced battery electric system. That powertrain is good for a whopping 1,160 hp and 664 lb-ft of torque.
The battery electric system from Rimac produces 106 hp and 206 lb-ft of torque on its own. The Cosworth V12 supplies the rest of the power. Aston Martin worked with Red Bull Advanced Technologies on the car. It noted that its partnership produced the powertrain as it is. Aston lists the high-revving F1 cars of the 1990s as a key influence.
According to Aston, the gasoline engine’s maximum horsepower is reached at a screaming 11,100 rpm and peak torque comes at 7,000 rpm. From there, the electric power system can add to the power output. The electric power system and the engine don’t operate separately, though, they augment each other and work together for maximum efficiency and maximum performance.
More Than Just a Power Mill
The V12 engine and gearbox both work as structural elements of the vehicle. This helps keep weight down and provides superb structural rigidity. Through the use of this unique construction, Aston has removed the need for an additional subframe. This highly unique feature alone would make the car special.
Vice President & Special Vehicle Operations Officer, David King seemed confident the new car would not disappoint. He said:
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. 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.
The British automaker said the development will continue on the car. Aston is currently building the prototypes of the car. It will be interesting to see how this project continues to progress as things move forward.
