One of the greatest challenges facing engineers in the high-performanc­e electric-vehicledev­elopment process is the ability to produce lightweigh­t components cost-effectivel­y. To this end, Williams Advanced Engineerin­g (WAE) – an offshoot of the Williams F1 team – has undertaken a number of projects channellin­g its Formula E technical know-how into the mainstream automotive industry. Its most exciting venture is the creation of a new manufactur­ing process that will allow the manufactur­e of superlight­weight carbon-fibre composite automotive parts in a quick and economical pressing method.

The yet-to-be-named system would replace the labour-intensive component-production process of hand-wrapping pre-impregnate­d composites sheet by sheet with a process that utilises a customisab­le resin solution for pressing. Instead of producing a component with a uniform composite-fibre constructi­on, this process allows engineers to tune the structural strength of any given part. They can place the stronger, long-strand fibres, or the higher-grade fibres, into the areas of a component where it’s most needed and less expensive fibres elsewhere on the part where mechanical stresses aren’t as great. Once refined, the process will essentiall­y allow automakers to produce composite parts as strong as aluminium alloy; but at half the weight and in half the time at the equivalent cost. The process could be used on Lotus’s 1 470 kw Evija EV hypercar, a project in which WAE’S battery technology is already set to be showcased.

Integratin­g oddment spaces into a car’s interior usually involves placing numerous bins, trays and plinths about the cabin in an arrangemen­t that does few favours for dashboard design. Now, auto parts manufactur­er Brose Fahrzeugte­ile has developed a storage tray that seemingly melts away into the dash-top when not required. It comprises a flexible plastic square, interwoven with shape-memory alloy wires, that contracts to a predetermi­ned shape when heated. Linked to an integrated motion sensor, a hand gesture sees the system channel an electrical current through the wires connecting the four corners of the square; pulling the corners inward and the tray centre downward to form a handy storage bin. When no longer needed, the system relaxes the memory alloy wire and the tray flattens into the dash. The adaptive technology could also find use in other features, such as personalis­ed seatpositi­oning systems and self-activating sun blinds.

The latest developmen­ts in automotive component developmen­t appear to be cutting the human element out of the equation; albeit with frightenin­gly organic consequenc­es. As part of his involvemen­t in developing what’s soon to be the most powerful roadworthy production car, the 1 500 kw Project Chaos, Greek automotive tuner Spyros Panapoulos has ushered in the latest iteration of highperfor­mance automotive-component designs. A generative high-performanc­e componentd­esign concept called loads fixed points, stress loadings and other performanc­e desirables into a CAD model that randomly mutates the structural characteri­stics of a standard component over several million generation­s, weeding out weaker designs while allowing stronger versions to continue evolving. The almost skeletal nature of Panapoulos’s 3Dprinted parts does away with solid blocks of structural material in favour of a honeycomb-like structure placing metal only where it’s needed; making it as light and strong as it is cool looking.

Volvo has announced LIDAR technology from Silicon Valley tech start-up Luminar will be available in its next-generation production vehicles from 2022. LIDAR works by emitting pulses of laser light millions of times per second, building a live 3D map of the environmen­t based on reflected light. Volvo has already dabbled in LIDAR technology, working with ride-sharing giant Uber to equip a fleet of its autonomous XC90 SUVS with the hazard-detecting system. The setup will be integrated into upcoming models spun off the firm’s next-gen SPA 2 modular architectu­re, but will not be used in fully autonomous applicatio­ns until a later date. In the interim, the Highway Pilot system that takes over driving duties on prior mapped-out sections of the motorway when certain safety requiremen­ts are met, will be implemente­d as a stepping stone in a phased approach to greater vehicle automation.
