A number of years in the past, Common Motors’ CEO Mary Barra outlined the corporate’s imaginative and prescient for zero crashes, zero congestion and nil emissions. GM is growing and rolling out numerous applied sciences associated to autonomous automobiles (AV), electrical automobiles (EV), sustainability and extra to acquire these bold objectives.
The corporate has pledged $27 billion in investments in EV and AV merchandise by 2025, together with the GMC Hummer EV and Cadillac CELESTIQ. In January, it unveiled the Ultium hyperscale battery platform that may function the muse for GM’s next-generation EV lineup. Designed for each mass market and high-performance automobiles, the Ultium will permit automobiles to go as much as 450 miles on a full cost.
GM additionally goals to realize a minimum of 50% sustainable materials content material in its automobiles by 2030, measured by complete car weight. Hitting this goal – and the others set forth by GM – requires collaboration amongst cross-functional groups, together with materials and product engineering. Composites Manufacturing journal sat down with Mark Voss, engineering group supervisor for physique constructions superior composites and pickup containers at GM, to debate the corporate’s imaginative and prescient for the longer term and the way composite supplies – and firms inside the composites trade – can assist GM meet its objectives.
CM: What are the most important engineering challenges dealing with GM right now?
Voss: The most important problem we’ve is tied to the management imaginative and prescient put in entrance of us – zero crashes, zero congestion, zero emissions. That actually defines our path for the foreseeable future. Clearly, electrification and car autonomy will likely be a giant a part of that. So, making automobiles that meet buyer expectations, whereas carrying out that zero, zero, zero initiative, is hands-down the most important engineering problem we face.
CM: Assembly all three objectives sounds arduous. You could discover options for every one individually, however then how do every of these particular person options impression the others?
Voss: It’s tough. And once more, we will’t simply meet our personal targets. It’s bought to be an built-in answer that the client is prepared to spend cash on, whereas concurrently being worthwhile for the corporate. However our engineers are up for the problem: With out that imaginative and prescient guiding us, we might be doing the identical factor again and again. So, we’re fortunate to have that imaginative and prescient and shift the trade in that course, too.
CM: What can firms within the composites trade do to raised place themselves as companions with GM and meet that triad of objectives you talked about?
Voss: GM is materials agnostic. We’re searching for supplies that greatest meet our objectives. These may very well be for a customer-facing know-how, such because the CarbonPro™ pickup beds or the outside physique panels of the Corvette Stingray. These light-weight composite elements supply a singular answer set that takes the client expertise to a different stage.
The supplies can also assist with car integration. I’ll cite crash vitality administration for instance. Electrical automobiles scale back emissions, however we nonetheless have to satisfy authorized standards and supply the occupant protected area inside the automobiles. So, vitality absorption is important. Composites have a singular benefit associated to their mass and vitality absorption per kilogram traits in comparison with different supplies.
General, we are attempting to emphasise to our companions the significance of actually understanding what their supplies do uniquely within the automotive area after which anticipating the challenges that GM has in implementing these supplies inside our automobiles and techniques. Image a brand new composite widget: I’ve to assemble it in our meeting crops, combine it into our physique outlets, paint it by way of our paint outlets and set up it in our common meeting outlets. It nonetheless has to satisfy our enterprise targets and be manufacturable at a sure items per hour foundation. Answering these questions up entrance – and being ready to clarify these new supplies and apply them in a manner that addresses all these issues – makes our activity of implementing applied sciences a lot simpler.
CM: That’s a useful message to our readers. Plenty of firms are enamored with the cool factor they will make combining this resin and that reinforcement. The answer could also be revolutionary, however is it usable?
Voss: That’s precisely it. We see all these distinctive alternatives, nevertheless it’s not sensible to discover them as deeply as is important to implement them on our automobiles. There’s simply not sufficient individuals and cash to do it. If a cloth provider has a singular materials, they need to work with a molder and a Tier 1 firm to achieve a stable understanding of what it takes to truly make a component.
CM: GM says that it’s searching for out-of-the-box pondering. Are you able to present some particular examples and areas of focus the place the corporate seeks revolutionary options?
Voss: There isn’t only one space as a result of we don’t wish to restrict the concepts. Let’s use the Corvette Stingray for instance. The ultra-lightweight GFRP “float” supplies and the way we used them within the frunk [front hood] and different areas of the car all derive from an revolutionary concept {that a} provider had. We’re searching for all the things – artistic materials options, course of options, integration options.
All the things has shifted considerably by the zero, zero, zero initiative. Issues like vitality absorption, half integration and packaging a big battery system into the car are so necessary. The worth stream isn’t absolutely vetted but, so there are alternatives in these areas to vary the equations in methods we haven’t seen but.
CM: What are you able to share about new improvements on the horizon at GM?
Voss: There’s a number of pleasure on the horizon. I can’t share particular improvements, however you possibly can have a look at latest examples to achieve perception on what we’re attempting to do from a car perspective.
Take a look at the Hummer EV, the primary all-electric supertruck, or the structure change within the Stingray with its mid-engine design and revolutionary use of composites. The zero, zero, zero initiative has spawned new and inventive concepts in how we execute the car and the way clients interface with the car. It’s all altering.
