Aston Martin partnered with Rimac for the electric part of the Valkyrie's powertrain.
The Aston Martin Valkyrie produces a total of 1,160 horsepower (865 kilowatts) and 664 pound-feet (900 Newton-meters) of torque, according to the newly released specs for the much-anticipated hypercar. It's Cosworth-built, 6.5-liter V12 can rev to an amazing 11,100 rpm and makes peak power at 10,500 revs.
"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," Aston Martin Vice President & Special Vehicle Operations Officer, David King said in the announcement of the specs. "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."
Of the Valkyrie's prodigious power, 1,000 horsepower (746 kW) and 546 lb-ft (740 Nm) comes from the naturally aspirated 6.5-liter V12. Meanwhile, the hybrid system from Rimac and Integral Powertrain Ltd. contributes 160 hp (119 kW) and 207 lb-ft (280 Nm).
Describing a vehicle as a race car for the street is a cliché, but it's an apt description for the Valkyrie. Aston Martin says that the V12 takes inspiration from the Formula 1 mills of the 1990s but "benefitting from two decades of progress in design, material, and manufacturing expertise." In addition, the engine and transmission function as stressed members of the vehicle, including acting as mounting points for the rear suspension.
For buyers who want the ultimate version of the Valkyrie and don't mind sacrificing the ability to drive the hypercar on the road, there's the optional AMR Track Performance Pack. The circuit-spec variant has revised body panels for better performance on the track, titanium brakes, magnesium wheels with carbon fiber aero rings, and different suspension settings. Aston Martin predicts the adjustments would make the Valkyrie eight-percent quicker around a track than the road-going model.
Aston Martin is building 150 examples of the Valkyrie, and there are already buyers for all of them, even with the machine's $3.2 million asking pricing. The first deliveries should begin before the end of the year.

ASTON MARTIN VALKYRIE - THE ULTIMATE HYBRID POWERTRAIN FOR THE ULTIMATE HYPERCAR
Aston Martin confirms performance figures for full hybrid powertrain
Aston Martin Valkyrie boasts maximum power of 1,160bhp @ 10,500rpm and peak combined torque of 900Nm at 6,000rpm
Naturally aspirated 6.5-litre V12 alone delivers 1,000bhp @ 10,500rpm and 740Nm @ 7000rpm
Battery-electric system by Rimac and Integral Powertrain Ltd. delivers additional 160bhp and 280Nm
Aston Martin Valkyrie the result of technical partnership between Aston Martin and Red Bull Advanced Technologies
First Aston Martin Valkyrie prototypes in build now
1 March 2019, Gaydon, England: With the first Aston Martin Valkyrie prototypes beginning to take shape, now is the time to reveal the full performance figures delivered by Aston Martin Valkyrie’s hybrid powertrain.
The heart of the Aston Martin Valkyrie’s powertrain is its clean sheet Cosworth-built 65° naturally aspirated 6.5-litre V12 engine. Evoking the spine-tingling, ultra-high-revving F1TM engines of the 1990s, but benefitting from two decades of progress in design, material and manufacturing expertise, it sets exceptional new standards for maximum rpm and weight.
With a certified peak power output of 1,000bhp (or 153.8 bhp-per-litre) at 10,500rpm, it can continue on to a maximum 11,100rpm. This is a world first for a naturally-aspirated, emissions-compliant road car. Peak torque is 740Nm at 7,000rpm. These peak outputs are purely delivered by the ICE (Internal Combustion Engine), with a further performance boost delivered by the battery hybrid system.
When describing the powertrain of a traditional road car, or even a conventional hybrid road car, it is easy to separate the main components and describe their individual roles. In the Aston Martin Valkyrie, where the design and engineering of each and every part has been approached with the meticulous ethos of Red Bull Advanced Technologies, out of their Formula One® DNA for maximum efficiency and ultimate performance, many key components do more than one job.
Using the Aston Martin Valkyrie’s powertrain as an 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.
The battery pack integrates all relevant sub-systems and serves as the carrier for the vehicle’s power electronics, while in addition to its Power Boost and Energy Recovery System functions, the E-Motor aids the mechanical performance of the gearbox. Aston Martin Valkyrie exemplifies intelligent engineering wherever you look.
A KERS-style boost system akin to those fitted to F1TM cars, the Aston Martin Valkyrie’s hybrid system has been developed by two main technical partners; Integral Powertrain Ltd, who supplied the bespoke electric motor, and Rimac for the lightweight hybrid battery system.
As a result, the full hybrid system contributes an additional 160bhp of power and a further 280Nm of available torque with the certified max power output of Aston Martin Valkyrie standing at a stunning 1,160bhp @ 10,500rpm. Equally, with the full hybrid system, peak torque will stand at 900Nm @ 6,000rpm.
Vice President & Special Vehicle Operations Officer, David King 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”.
Development of the Aston Martin Valkyrie continues under the guidance of Aston Martin Lagonda, Red Bull Advanced Technologies and project partner AF Racing.
