Not too long ago, we read about the Aston Martin Valkyrie’s naturally aspirated 6.5-litre V12 that revs up to 11,100 rpm. Now though, it’s time for some official output figures.
Speaking of which, the Cosworth-built motor is confirmed to produce 1,000 bhp (or 153.8 bhp-per-litre) at 10,500 rpm and 740 Nm of torque at 7,000 rpm. These outputs are purely from the ICE. In addition, there’s an electric motor from Integral Powertrain that offers an extra 160 bhp and 280 Nm of torque.
As a result, the total system output would be 1,160 bhp and 900 Nm of torque. The battery pack is supplied by Rimac Automobili with a KERS-style boost system akin to those fitted to F1 cars.

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 with even greater structural rigidity and eliminating the weight of an additional rear subframe.
As for the gearbox, it’s a Ricardo-sourced 7-speed dual-clutch unit with paddle shifters.
“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,” said David King, Vice President & Special Vehicle Operations Officer.
