The Aston Martin Valkyrie Combines Formula 1 Tech of Past and Present
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-degree naturally aspirated 6.5-liter V12 engine. Evoking the spine-tingling, ultra-high-revving F1 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 1,000 horsepower (or 153.8 bhp-per-liter) at 10,500 rpm, it can continue on to a maximum 11,100 rpm. This is a world first for a naturally-aspirated, emissions-compliant road car. Peak torque is 740 Nm 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, 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.
Meanwhile, 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.
A KERS-style boost system akin to those fitted to F1 cars, the Aston Martin Valkyrie’s hybrid system contributes an additional 160 horsepower and a further 280Nm of available torque with the certified max power output of Aston Martin Valkyrie standing at a stunning 1,160 horsepower at 10,500 rpm. Equally, with the full hybrid system, peak torque will stand at 900 Nm at 6,000rpm.
Development of the Aston Martin Valkyrie continues under the guidance of Aston Martin Lagonda, Red Bull Advanced Technologies, and project partner AF Racing.
