Aston Martin has finally confirmed powertrain specifications for its upcoming Valkyrie hypercar, which will produce a combined 1,160 HP at 10,500 rpm and 900 Nm of torque at 6,000 rpm, even more than what was previously reported.

Its Rimac-sourced battery electric system alone is responsible for an additional 160 HP and 280 Nm, while the naturally aspirated 6.5-liter V12 delivers a full 1,000 HP and 740 Nm of torque – that’s 153.8 HP per liter. The Valkyrie is a result of an extensive technical partnership between Aston Martin and Red Bull Advanced Technologies, so it’s no wonder that it’s ultra high-revving engine would be reminiscent of Formula 1 engines from the 1990s.

Unlike with traditional road cars, many key components in the Valkyrie are tasked to do more than just one job. For example, both the V12 engine and the gearbox casing act as stressed members of the vehicle structure. The latter provides rear suspension mounting points, while also adding structural rigidity and eliminating the weight of an additional rear subframe. Meanwhile, the battery pack also serves as the carrier for the Valkyrie’s power electronics.

The British luxury sports car maker has also announced that the first Valkyrie prototypes are now being built.
