at a significant automotive producer, watching engineers rejoice what they thought was a breakthrough. They’d used generative AI to optimize a suspension part: 40% weight discount whereas sustaining structural integrity, accomplished in hours as an alternative of the same old months. The room buzzed with pleasure about effectivity positive aspects and value financial savings.
However one thing bothered me. We had been utilizing know-how that might reimagine transportation from scratch, and as an alternative, we had been making barely higher variations of components we’ve been manufacturing for the reason that Fifties. It felt like utilizing a supercomputer to steadiness your checkbook: technically spectacular, however lacking the purpose solely.
After spending three years serving to automotive corporations deploy AI options, I’ve seen this sample all over the place. The trade is making a elementary mistake: treating generative AI as an optimization software when it’s truly a reimagination engine. And this misunderstanding may cost a little conventional automakers their future.
Why This Issues Now
The automotive trade stands at an inflection level. Electrical automobiles have eliminated the central constraint that formed automotive design for a century—the inner combustion engine. But most producers are nonetheless designing EVs as if they should accommodate an enormous steel block below the hood. They’re utilizing AI to make these outdated designs marginally higher, whereas a handful of corporations are utilizing the identical know-how to ask whether or not automobiles ought to appear like automobiles in any respect.
This isn’t nearly know-how; it’s about survival. The businesses that determine this out will dominate the subsequent period of transportation. Those who don’t will be part of Kodak and Nokia within the museum of disrupted industries.
The Optimization Entice: How We Bought Right here
What Optimization Seems to be Like in Apply
In my consulting work, I see the identical deployment sample at nearly each automotive producer. A workforce identifies a part that’s costly or heavy. They feed present designs right into a generative AI system with clear constraints: cut back weight by X%, keep power necessities, keep inside present manufacturing tolerances. The AI delivers, everybody celebrates the ROI, and the undertaking will get marked as a hit.
Right here’s precise code from a conventional optimization method I’ve seen applied:
from scipy.optimize import reduce
import numpy as np
def optimize_component(design_params):
"""
Conventional method: optimize inside assumed constraints
Downside: We're accepting present design paradigms
"""
thickness, width, peak, material_density = design_params
# Decrease weight
weight = thickness * width * peak * material_density
# Constraints based mostly on present manufacturing
constraints = [
{'type': 'ineq', 'fun': lambda x: x[0] * x[1] * 1000 - 50000},
{'sort': 'ineq', 'enjoyable': lambda x: x[0] - 0.002}
]
# Bounds from present manufacturing capabilities
bounds = [(0.002, 0.01), (0.1, 0.5), (0.1, 0.5), (2700, 7800)]
consequence = reduce(
lambda x: x[0] * x[1] * x[2] * x[3], # weight perform
[0.005, 0.3, 0.3, 7800],
methodology='SLSQP',
bounds=bounds,
constraints=constraints
)
return consequence # Yields 10-20% enchancment
# Instance utilization
initial_design = [0.005, 0.3, 0.3, 7800] # thickness, width, peak, density
optimized = optimize_component(initial_design)
print(f"Weight discount: {(1 - optimized.enjoyable / (0.005*0.3*0.3*7800)) * 100:.1f}%")This method works. It delivers measurable enhancements — usually 10-20% weight discount, 15% value financial savings, that type of factor. CFOs like it as a result of the ROI is obvious and quick. However take a look at what we’re doing: we’re optimizing inside constraints that assume the present design paradigm is right.
The Hidden Assumptions
Each optimization embeds assumptions. While you optimize a battery enclosure, you’re assuming batteries ought to be enclosed in separate housings. While you optimize a dashboard, you’re assuming automobiles want dashboards. While you optimize a suspension part, you’re assuming the suspension structure itself is right.
Normal Motors introduced final 12 months they’re utilizing generative AI to revamp car elements, projecting 50% discount in improvement time. Ford is doing comparable work. So is Volkswagen. These are actual enhancements that may save hundreds of thousands of {dollars}. I’m not dismissing that worth.
However right here’s what retains me up at night time: whereas conventional producers are optimizing their present architectures, Chinese language EV producers like BYD, which surpassed Tesla in world EV gross sales in 2023, are utilizing the identical know-how to query whether or not these architectures ought to exist in any respect.
Why Good Individuals Fall into This Entice
The optimization lure isn’t about lack of intelligence or imaginative and prescient. It’s about organizational incentives. While you’re a public firm with quarterly earnings calls, you’ll want to present outcomes. Optimization delivers measurable, predictable enhancements. Reimagination is messy, costly, and may not work.
I’ve sat in conferences the place engineers introduced AI-generated designs that might cut back manufacturing prices by 30%, solely to have them rejected as a result of they’d require retooling manufacturing strains. The CFO does the mathematics: $500 million to retool for a 30% value discount that takes 5 years to pay again, versus $5 million for optimization that delivers 15% financial savings instantly. The optimization wins each time.
That is rational decision-making inside present constraints. It’s additionally the way you get disrupted.

Actual-World Examples of Reimagination
Autodesk demonstrated this with their generative design of a chassis part. As an alternative of asking “how can we make this half lighter,” they requested “what’s the optimum construction to deal with these load instances?” The consequence: a design that lowered half rely from eight items to at least one whereas chopping weight by 50%.
The design appears alien: natural, nearly organic. That’s as a result of it’s not constrained by assumptions about how components ought to look or how they’ve historically been manufactured. It emerged purely from bodily necessities.
Right here’s what I imply by “alien”: think about a automotive door body that doesn’t appear like a rectangle with rounded corners. As an alternative, it appears like tree branches — natural, flowing constructions that comply with stress strains. In a single undertaking I consulted on, this method lowered the door body weight by 35% whereas truly bettering crash security by 12% in comparison with conventional stamped metal designs. The engineers had been skeptical till they ran the crash simulations.
The revealing half: after I present these designs to automotive engineers, the commonest response is “clients would by no means settle for that.” However they mentioned the identical factor about Tesla’s minimalist interiors 5 years in the past. Now everybody’s copying them. They mentioned it about BMW’s kidney grilles getting bigger. They mentioned it about touchscreens changing bodily buttons. Buyer acceptance follows demonstration, not the opposite method round.
The Chassis Paradigm
For 100 years, we’ve constructed automobiles round a elementary precept: the chassis gives structural integrity, the physique gives aesthetics and aerodynamics. This made good sense whenever you wanted a inflexible body to mount a heavy engine and transmission.
However electrical automobiles don’t have these constraints. The “engine” is distributed electrical motors. The “gasoline tank” is a flat battery pack that may function a structural factor. But most EV producers are nonetheless constructing separate chassis and our bodies as a result of that’s how we’ve at all times achieved it.
While you let generative AI design car construction from scratch with out assuming chassis/physique separation it produces built-in designs the place construction, aerodynamics, and inside area emerge from the identical optimization course of. These designs will be 30-40% lighter and 25% extra aerodynamically environment friendly than conventional architectures.
I’ve seen these designs in confidential classes with producers. They’re bizarre. They problem each assumption about what a automotive ought to appear like. Some look extra like plane fuselages than automotive our bodies. Others have structural components that move from the roof to the ground in curves that appear random however are literally optimized for particular crash eventualities. And that’s precisely the purpose they’re not constrained by “that is how we’ve at all times achieved it.”
The Actual Competitors Isn’t Who You Assume
The Tesla Lesson
Conventional automakers assumed their competitors was different conventional automakers, all taking part in the identical optimization recreation with barely totally different methods. Then Tesla confirmed up and altered the principles.
Tesla’s Giga casting course of is an ideal instance. They use AI-optimized designs to exchange 70 separate stamped and welded components with single aluminum castings. This wasn’t doable by asking “how can we optimize our stamping course of?” It required asking “what if we rethought car meeting solely?”
The outcomes communicate for themselves: Tesla achieved revenue margins of 16.3% in 2023, in comparison with conventional automakers averaging 5-7%. That’s not simply higher execution; it’s a special recreation.
Let me break down what this truly means in follow:
| Metric | Conventional OEMs | Tesla | Distinction |
| Revenue Margin | 5-7% | 16.3% | +132% |
| Elements per rear underbody | 70+ items | 1-2 castings | -97% |
| Meeting time | 2-3 hours | 10 minutes | -83% |
| Manufacturing CapEx per car | $8,000-10,000 | $3,600 | -64% |
These aren’t incremental enhancements. That is structural benefit.
The China Issue
Chinese language producers are shifting even additional. NIO’s battery-swapping stations, which change a depleted battery in below three minutes, emerged from asking whether or not car vary ought to be solved via larger batteries or totally different infrastructure. That’s a reimagination query, not an optimization query.
Take into consideration what this truly means: as an alternative of optimizing battery chemistry or charging pace the questions each Western producer is asking, NIO requested “what if the battery doesn’t want to remain within the automotive?” This fully sidesteps vary nervousness, eliminates the necessity for large battery packs, and creates a subscription income mannequin. It’s not a greater reply to the previous query; it’s a special query solely.
BYD’s vertical integration — they manufacture all the things from semiconductors to finish automobiles — permits them to make use of generative AI throughout your entire worth chain fairly than simply optimizing particular person elements. While you management the total stack, you may ask extra elementary questions on how the items match collectively.
I’m not saying Chinese language producers will essentially win. However they’re asking totally different questions, and that’s harmful for corporations nonetheless optimizing inside previous paradigms.
The Sample of Disruption
This is identical sample we’ve seen in each main trade disruption:
Kodak had the primary digital digital camera in 1975. They buried it as a result of it will cannibalize movie gross sales and their optimization mindset couldn’t accommodate reimagination. They saved optimizing movie high quality whereas digital cameras reimagined pictures solely.
Nokia dominated cell phones by optimizing {hardware} and manufacturing. That they had the perfect construct high quality, longest battery life, most sturdy telephones. Then Apple requested whether or not telephones ought to be optimized for calling or for computing. Nokia saved making higher telephones; Apple made a pc that might make calls.
Blockbuster optimized their retail expertise: higher retailer layouts, extra stock, quicker checkout. Netflix requested whether or not video rental ought to occur in shops in any respect.
The know-how wasn’t the disruption. The willingness to ask totally different questions was.
And right here’s the uncomfortable reality: after I speak to automotive executives, most can recite these examples. They know the sample. They only don’t consider it applies to them as a result of “automobiles are totally different” or “now we have bodily constraints” or “our clients count on sure issues.” That’s precisely what Kodak and Nokia mentioned.
What Really Must Change
Why “Be Extra Modern” Doesn’t Work
The answer isn’t merely telling automakers to “be extra progressive.” I’ve sat via sufficient technique classes to know that everybody desires to innovate. The issue is structural.
Public corporations face quarterly earnings stress. Ford has $43 billion invested in manufacturing amenities globally. You possibly can’t simply write that off to strive one thing new. Seller networks count on a gentle provide of automobiles that look and performance like automobiles. Provider relationships are constructed round particular elements and processes. Regulatory frameworks assume automobiles may have steering wheels, pedals, and mirrors.
These aren’t excuses, they’re actual constraints that make reimagination genuinely tough. However some modifications are doable, even inside these constraints.
Sensible Steps Ahead
1. Create genuinely impartial innovation models
Not “innovation labs” that report back to manufacturing engineering and get judged by manufacturing metrics. Separate entities with totally different success standards, totally different timelines, and permission to problem core assumptions. Give them actual budgets and actual autonomy.
Amazon does this with Lab126 (which created Kindle, Echo, Fireplace). Google did it with X (previously Google X, which developed Waymo, Wing, Loon). These models can fail repeatedly as a result of they’re not measured by quarterly manufacturing targets. That freedom to fail is what allows reimagination.
Right here’s what this appears like structurally:
- Separate P&L: Not a price middle inside manufacturing, however its personal enterprise unit
- Completely different metrics: Measured on studying and possibility worth, not quick ROI
- 3–5-year timelines: Not quarterly or annual targets
- Permission to cannibalize: Explicitly allowed to threaten present merchandise
- Completely different expertise: Researchers and experimenters, not manufacturing engineers
2. Associate with generative AI researchers
Most automotive AI deployments deal with quick manufacturing purposes. That’s tremendous, however you additionally want groups exploring chance areas with out quick manufacturing constraints.
Companions with universities, AI analysis labs, or create inside analysis teams that aren’t tied to particular product timelines. Allow them to ask silly questions like “what if automobiles didn’t have wheels?” Most explorations will lead nowhere. The few that lead someplace will probably be transformative.
Particular actions:
- Fund PhD analysis at MIT, Stanford, CMU on automotive purposes of generative AI.
- Create artist-in-residence applications bringing industrial designers to work with AI researchers.
- Sponsor competitions (like DARPA Grand Problem) for radical car ideas.
- Publish analysis brazenly attracts expertise by being the place attention-grabbing work occurs.
3. Interact clients in another way
Cease asking clients what they need inside present paradigms. After all they’ll say they need higher vary, quicker charging, extra snug seats. These are optimization questions.
As an alternative, present them what’s doable. Tesla didn’t ask focus teams whether or not they wished a 17-inch touchscreen changing all bodily controls. They constructed it, and clients found they beloved it. Typically you’ll want to present folks the longer term fairly than asking them to think about it.
Higher method:
- Construct idea automobiles that problem assumptions
- Let clients expertise radically totally different designs
- Measure reactions to precise prototypes, not descriptions
- Focus teams ought to react to prototypes, not think about potentialities
4. Acknowledge what recreation you’re truly taking part in
The competitors isn’t about who optimizes quickest. It’s about who’s keen to query what we’re optimizing for.
A McKinsey research discovered that 63% of automotive executives consider they’re “superior” in AI adoption, primarily citing optimization use instances. In the meantime, another person is utilizing the identical know-how to query whether or not we want steering wheels, whether or not automobiles ought to be owned or accessed, whether or not transportation ought to be optimized for people or communities.
These are reimagination questions. And should you’re not asking them, another person is.
