It demonstrates Aston Martin’s breadth of capabilities with the technical help and experience of Method 1.”
The technical crossover between Aston Martin and its eponymous Method 1 group, which at the moment sits in fourth place within the FIA Method One World Constructors’ Championship, is facilitated by the consulting arm of the group, Aston Martin Efficiency Applied sciences (AMPT). AMPT is immediately helping Aston Martin’s efficiency engineering group in three crucial areas of growth – dynamics, aerodynamics and supplies.
Claudio Santoni, Aston Martin Efficiency Applied sciences Engineering Director, mentioned: “It’s a nice benefit for a automobile producer to have entry to the distinctive expertise and information of a Method 1 group. F1 engineers are continually pushing the boundaries within the pursuit of efficiency and have developed fast problem-solving instruments. With this in-house information, we are able to seamlessly convey F1 experience to highway automobile growth.”
Aston Martin Valhalla Driving Dynamics
Aston Martin Valhalla is a really driver-focused mid-engine supercar, and the car dynamics group, in shut conjunction with AMPT, is working full throttle to ship the pinpoint dynamics that may present unprecedented driver engagement. F1 design depends closely on simulation instruments and the strategies used to make sure that each second spent within the simulator brings progress has been put in place for Valhalla. 90% of the dynamic traits and car set-up has been accomplished within the simulator, with the ultimate growth part accomplished in the actual world, on the highway and observe.
Worthwhile enter from the AMF1 drivers provides a brand new depth to the calibration of Valhalla. The elite-level expertise and information of drivers like Lance Stroll and Fernando Alonso can take car dynamics to a brand new stage as they push the automobile to the acute fringe of its efficiency capabilities.
The cockpit ergonomics of Valhalla have additionally benefited by taking direct cues from Method 1, in that the driving place has been optimised with help from AMPT to offer the motive force with race automobile stage management to maximise the pleasure of driving. The motive force’s heels are raised by a false ground, which additionally incorporates digital modules, and the distinctive carbon fibre bucket seat will be reclined to a higher angle to realize a seating place extra carefully aligned to the AMR23 race automobile while nonetheless providing highway automobile consolation. This aids in maintaining a low roofline and ensures the motive force feels genuinely related to the car.
Aston Martin Valhalla Aerodynamics
The joint experience of each AMPT and Aston Martin’s aerodynamicists in highway vehicles and Method 1 permits the model to create addictive highway vehicles with the right mix of luxurious and efficiency. A fast have a look at the underbody of the AMR23 and the underbody of Valhalla, the place most of its downforce is generated, illustrates how a lot F1 know-how has gone into the brand new supercar.
The aerodynamic strategy to Valhalla begins equally to an F1 automobile by utilizing all components of the physique form to generate downforce and minimise drag. Nevertheless, Valhalla will not be restricted by F1 laws, so it could profit from absolutely lively aerodynamic programs at each the entrance and rear of the automobile, which can generate over 600kg of downforce at 240km/h. This permits Valhalla to continually adapt entrance and rear downforce to maximise grip, steadiness, consistency, or cut back drag relying on the state of affairs and the chosen driving mode. This permits drivers to extract the perfect from Valhalla’s chassis and tyres throughout your complete efficiency vary of the automobile.

Just like the AMR23 race automobile, Valhalla options a number of factor wings entrance and rear, although the entrance wing is essentially hidden from view. The entrance wing can lie flat in a DRS place to scale back drag or be angled as much as generate large downforce immediately forward of the entrance wheels. Behind the entrance splitter, the under-floor floor is concave, making a low-pressure space that produces downforce. Once more, this function will be managed as a part of the automobile’s full car lively management algorithms.
The multi-element rear wing lies flat to create the attractive, clear strains of the automobile while producing a baseline stage of downforce with minimal drag. Nevertheless, the wing is raised excessive into the airflow in observe mode to maximise effectiveness. The automobile then actively manages the wing’s angle of assault to steadiness between most downforce and DRS to maximise efficiency frequently.
Impressed by F1 vortex mills and aero options, small slotted louvers on the sill, simply forward of the rear wheel, act as mini diffusers to drag airflow out and upwards from below the automobile, rising downforce. A roof-mounted snorkel feeds each the engine consumption, because it does in F1, but in addition serves to feed cooling ducts for turbo intercoolers and to chill the engine’s Scorching-V turbo configuration.
The huge information of Computational Fluid Dynamics (CFD) and wind tunnel testing in F1, along with AMPT, has dramatically benefited highway automobile engineers. The identical aerodynamic tooling methods used to create the AMR23 race automobile have been used to develop the aerodynamics for Valhalla.
The Valhalla engineering group working immediately with AMPT utilised the identical CFD software program because the AMF1 group, together with learnings on mannequin set-up. As in Method 1, Valhalla has used a scale mannequin and shifting highway wind tunnel to develop the automobile, finding out the identical processes, together with journey peak sensitivity, the results of yaw, roll and pitch, steering and so forth.
Supplies
AMPT and the AMF1 group have been constructing vehicles from carbon fibre for a few years, so there’s little or no they don’t perceive about supplies. Nevertheless, the concept of constructing 999 carbon fibre monocoques will likely be a novelty to a group used to constructing only a handful of vehicles per season. The AMPT carbon applied sciences group works on creating concepts that advanced in F1 and making use of the identical strategy to Valhalla. This has dramatically benefited areas such because the simulation of stiffness and crashworthiness testing, the place important positive aspects will be made by figuring out any vulnerabilities earlier than the harmful means of crash testing begins.
The construction on the coronary heart of Valhalla is crafted to maximise stiffness with minimal weight, guaranteeing most management with millimetric precision. Designed and engineered by AMPT, which applies their extremely specialised F1 experience and technical capabilities past the top of motorsport, Valhalla’s construction is the product of cutting-edge composite know-how.
A posh and beautiful mix of carbon fibre supplies, Valhalla’s carbon construction has been created utilizing a novel and proprietary know-how developed for Aston Martin. The higher and decrease sections of the construction are moulded from carbon fibre utilizing a mixture of the Resin-Switch-Moulding course of (RTM) and F1-derived autoclave know-how. The result’s a singular, immensely stiff, strong, gentle passenger cell that delivers best-in-class dynamic structural attributes and excellent security with out compromising driver and passenger ergonomics.
Valhalla is on the forefront of Aston Martin’s transition from inside combustion to hybrid to full electrification. A lot has been realized inside the engine administration group to optimise efficiency and maximise efficiencies of Valhalla’s bespoke twin-turbo flat-plane V8 engine, which is essentially the most superior, responsive and highest-performing V8 engine ever fitted to an Aston Martin and, when mated with three e-motors, creates a 1,012 PS hybrid all-wheel-drive hybrid powertrain.
Twin electrical motors on the entrance axle allow Valhalla to not solely function four-wheel drive but in addition enable the engineers full unbiased management of the torque utilized at every of the entrance wheels – a way often called torque vectoring. Torque Vectoring allows a extra constructive steering response at turn-in, firmer grip by means of the nook and improved traction on nook exit. They’re enhancing the driving expertise and efficiency by means of all phases of the nook. The entrance e-motors additionally present the reverse perform, saving weight on the rear transmission. A 3rd e-motor is built-in into the transmission, offering further energy to the rear wheels in addition to performing because the starter/generator for the ICE engine.
Carlo Della Casa, Aston Martin Product Improvement Director, mentioned: “The information and expertise of the AMF1 group personnel at Aston Martin Efficiency Applied sciences mixed with the talents and know-how of our highway automobile growth groups has enabled us to convey direct F1 learnings to sportscar growth. Our goal for Valhalla is to supply a supercar that may set best-in-class requirements for efficiency, dynamics and driving pleasure. Valhalla will use lively applied sciences to scale back the hole between the “Gents driver” and the skilled one on observe. Having open entry to the information inside the AMF1 group has been an enormous benefit for us as we develop this unbelievable automobile.”
The primary operating prototype will take to the highway later this yr, with Valhalla set to enter manufacturing in 2024.
