The technical crossover between Aston Martin and its eponymous Formula 1 staff, which presently sits in fourth place within the FIA Formula One World Constructors’ Championship, is facilitated by the consulting arm of the staff, Aston Martin Performance Technologies (AMPT). AMPT is straight helping Aston Martin’s efficiency engineering staff in three crucial areas of growth – dynamics, aerodynamics and supplies.
Claudio Santoni, Aston Martin Performance Technologies Engineering Director, mentioned: “It is a great advantage for a car manufacturer to have access to the unique skills and knowledge of a Formula 1 team. F1 engineers are constantly pushing the boundaries in the pursuit of performance and have developed rapid problem-solving tools. With this in-house knowledge, we can seamlessly bring F1 expertise to road car development.”
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 can 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 section accomplished in the true world, on the highway and monitor.
Valuable enter from the AMF1 drivers provides a brand new depth to the calibration of Valhalla. The elite-level abilities and data of drivers like Lance Stroll and Fernando Alonso can take car dynamics to a brand new degree as they push the automotive to the acute fringe of its efficiency capabilities.
The cockpit ergonomics of Valhalla have additionally benefited by taking direct cues from Formula 1, in that the driving place has been optimised with assist from AMPT to offer the driving force with race automotive degree management to maximise the pleasure of driving. The driver’s heels are raised by a false ground, which additionally incorporates digital modules, and the distinctive carbon fibre bucket seat may be reclined to a larger angle to attain a seating place extra carefully aligned to the AMR23 race automotive while nonetheless providing highway automotive consolation. This aids in preserving a low roofline and ensures the driving force feels genuinely related to the car.
Aston Martin Valhalla Aerodynamics
The joint experience of each AMPT and Aston Martin’s aerodynamicists in highway automobiles and Formula 1 permits the model to create addictive highway automobiles 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 method to Valhalla begins equally to an F1 automotive by utilizing all parts of the physique form to generate downforce and minimise drag. However, Valhalla isn’t restricted by F1 laws, so it may profit from totally energetic aerodynamic methods at each the entrance and rear of the automotive, which is able to generate over 600kg of downforce at 240km/h. This allows Valhalla to continuously adapt entrance and rear downforce to maximise grip, steadiness, consistency, or scale back drag relying on the scenario and the chosen driving mode. This allows drivers to extract the easiest from Valhalla’s chassis and tyres throughout all the efficiency vary of the automotive.

Like the AMR23 race automotive, Valhalla options a number of ingredient wings entrance and rear, although the entrance wing is basically 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 straight forward of the entrance wheels. Behind the entrance splitter, the under-floor floor is concave, making a low-pressure space that produces downforce. Again, this function may be managed as a part of the automotive’s full car energetic management algorithms.
The multi-element rear wing lies flat to create the attractive, clear traces of the automotive while producing a baseline degree of downforce with minimal drag. However, the wing is raised excessive into the airflow in monitor mode to maximise effectiveness. The automotive then actively manages the wing’s angle of assault to steadiness between most downforce and DRS to maximise efficiency regularly.
Inspired 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 beneath the automotive, growing 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 Hot-V turbo configuration.
The huge data of Computational Fluid Dynamics (CFD) and wind tunnel testing in F1, along with AMPT, has dramatically benefited highway automotive engineers. The identical aerodynamic tooling strategies used to create the AMR23 race automotive have been used to develop the aerodynamics for Valhalla.
The Valhalla engineering staff working straight with AMPT utilised the identical CFD software program because the AMF1 staff, together with learnings on mannequin set-up. As in Formula 1, Valhalla has used a scale mannequin and shifting highway wind tunnel to develop the automotive, finding out the identical processes, together with experience peak sensitivity, the results of yaw, roll and pitch, steering and so forth.
Materials
AMPT and the AMF1 staff have been constructing automobiles from carbon fibre for a few years, so there may be little or no they don’t perceive about supplies. However, the concept of constructing 999 carbon fibre monocoques might be a novelty to a staff used to constructing only a handful of automobiles per season. The AMPT carbon applied sciences staff works on creating concepts that developed in F1 and making use of the identical method to Valhalla. This has dramatically benefited areas such because the simulation of stiffness and crashworthiness testing, the place vital features may be made by figuring out any vulnerabilities earlier than the damaging technique 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 fancy 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-Transfer-Moulding course of (RTM) and F1-derived autoclave know-how. The result’s a singular, immensely stiff, sturdy, mild 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 inner combustion to hybrid to full electrification. Much has been realized throughout 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 permit the engineers full unbiased management of the torque utilized at every of the entrance wheels – a method generally known as 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 are enhancing the driving expertise and efficiency by means of all phases of the nook. The entrance e-motors additionally present the reverse operate, 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 Development Director, mentioned: “The knowledge and experience of the AMF1 team personnel at Aston Martin Performance Technologies combined with the skills and know-how of our road car development teams has enabled us to bring direct F1 learnings to sportscar development. Our target for Valhalla is to produce a supercar that will set best-in-class standards for performance, dynamics and driving pleasure. Valhalla will use active technologies to reduce the gap between the “Gentlemen driver” and the skilled one on monitor. Having open entry to the data throughout the AMF1 staff has been an enormous benefit for us as we develop this unbelievable automotive.”
The first operating prototype will take to the highway later this yr, with Valhalla set to enter manufacturing in 2024.
