Aston Martin reveals the first images of its first hybrid supercar, the Aston Martin Valhalla, while the prototypes begin their testing phase.
With its V8 biturbo flat-plane engine coupled to three electric motors to create a four-wheel drive hybrid propulsion system that delivers a system power of 1,012 HP, the Valhalla leads Aston Martin’s transition from internal combustion to combustion. hybrid and total electrification.
The Valhalla is at the forefront of Aston Martin’s transition from internal combustion to electrification. The performance has been optimized and the efficiency of the Valhalla’s flat twin-turbo V8 engine has been optimized – the most advanced, responsive and highest-performing V8 ever fitted to an Aston Martin. Combined with three electric motors, the result is a 1,012 HP four-wheel drive hybrid propulsion system.
Two electric motors on the front axle allow the Valhalla not only to have four-wheel drive, but also completely independent control of the torque applied to each of the front wheels, a technique known as “torque vectoring” or active torque vectoring. .
The Aston Martin Valhalla will go into production in 2024, and will be manufactured in a limited series of 999 units. Aston Martin’s first hybrid supercar benefits significantly from Formula 1 capabilities, technical support and expertise through Aston Martin Performance Technologies.
Aston Martin Valhalla
F. P.
The Aston Martin Valhalla is a truly driver-oriented mid-engine supercar. The vehicle dynamics team, in close collaboration with AMPT, is working flat out to achieve precise dynamic behavior that provides an unprecedented driver experience. The design of an F1 relies heavily on simulation tools; and the methods used to ensure that every moment spent in the simulator brings progress, have been put into practice in Valhalla. In fact, 90% of the vehicle’s dynamic characteristics and tuning have been carried out in the simulator, while the final phase of development has been completed in the real world, on the road and on the track.
The ergonomics of the Valhalla cockpit also benefit from direct cues from Formula 1: the position behind the wheel has been optimized with the support of AMPT to provide the driver with control at the level of a racing car, in order to Maximize driving pleasure. The heels are raised by a false floor that also contains electronic modules, and the carbon fiber bucket seat can be reclined to achieve a position more similar to that of the AMR23 single-seater, while still offering the comfort of a road car. This helps maintain a low roofline and ensures the driver feels truly connected to the car.
Aerodynamics
The combined experience of AMPT and Aston Martin aerodynamic specialists, both in road cars and Formula 1, gives the brand the opportunity to create addictive cars with the perfect combination of luxury and performance. A quick look at the underbody of the AMR23 and those of the Valhalla, where most of its downforce is generated, illustrates how much racing technology has been incorporated into the new supercar.
The Valhalla’s aerodynamic approach begins similarly to that of an F1 car, using all body elements to generate downforce and minimize drag. However, the Valhalla is not limited by F1 rules, so it can benefit from fully active aerodynamic systems at both the front and rear, which will generate more than 600 kg of downforce at a speed of 240 km/h.
This way the Valhalla can constantly adapt front and rear downforce to maximize grip, balance and consistency; or reduce the resistance depending on the situation and the selected driving mode. This allows drivers to get the best out of the Valhalla’s chassis and tires across the car’s full range of performance.
Like the AMR23 racing car, the Valhalla has front and rear spoilers made up of multiple elements, although the front one is hidden from view and can be flat in the DRS position to reduce aerodynamic drag or tilted upwards to generate enormous downforce. directly in front of the front wheels. Behind the front splitter the underfloor surface is concave, creating a low pressure zone that generates additional downforce. Again, this feature can be controlled as part of the vehicle’s active control algorithms.
The rear wing is flat to shape the car’s beautiful, clean lines, while generating a basic level of downforce with minimal drag. However, in circuit mode it is raised to maximize its effectiveness. The car actively manages the angle of attack of the wing to continuously balance maximum downforce and DRS, in order to maximize performance.
Inspired by the vortex generators and aerodynamic features of F1, the small slotted grilles on the side sills, just in front of the rear wheels, act as mini diffusers to extract and raise airflow from under the car, increasing downforce. aerodynamics. An air intake on the roof feeds both the engine intake – just like in F1 – and the cooling ducts for the turbo intercoolers and to cool the Hot-V configuration of the engine.
The Valhalla’s heart structure is designed to maximize rigidity with minimal weight, ensuring maximum control with millimeter precision. Designed and manufactured by AMPT, which applies its highly specialized F1 experience and technical capabilities beyond the pinnacle of motorsport, the Valhalla structure is the product of cutting-edge composite technology.
The Valhalla’s carbon structure, a complex and exquisite blend of carbon fiber materials, has been created using a novel patented technology developed for Aston Martin. The upper and lower sections of the frame are molded in carbon fiber using a combination of the resin transfer molding (RTM) process and autoclave technology derived from F1. The result is a unique, immensely rigid, strong and lightweight cabin that offers best-in-class dynamic structural attributes and outstanding safety, without compromising driver and passenger ergonomics.
