The design review went global. The decision didn't get easier.
For seventy years the most important moment in car design happened outdoors. The clay model rolled out of the studio into a viewing courtyard, the design chief walked a slow circle around it in real daylight, and a decision got made that committed billions in tooling. The light was free, the surface was real, and everyone judging it stood in the same place at the same time.
That ritual is being dismantled right now. The courtyard is becoming a wall.
Across the industry the 1:1 review is moving onto powerwalls and CAVE rooms — floor-to-ceiling stereoscopic projection where a full-size virtual car can be reviewed by teams on three continents at once. Ford has issued VR kits to engineers and directors worldwide and now runs live design reviews inside a shared "digital hangar," rendered in full 3D for headset users and flat 2D for everyone else. At CES 2026 the British consultancy Avant built its Longbow electric sports car almost entirely through Varjo XR headsets and a virtual studio, collapsing months of physical modelling into a workflow where the review and the model are the same artifact. A review that once required flying a dozen executives to one campus now happens in an afternoon.
The efficiency case is overwhelming, and it is real. You cut weeks of travel to hours. You cut the cost of a second full-scale clay. You let a studio in Shanghai and a studio in Cologne stand in front of the identical surface in the identical virtual light. For globally distributed teams — which is now every serious OEM — this is not a gadget. It is the new geometry of the decision.
But notice what the powerwall quietly changes. It does not just relocate the review. It re-engineers the conditions under which judgment happens — and judgment, not the picture, is the actual product of a design review.
The viewing courtyard was a brutal, honest instrument precisely because it was uncontrolled. Real sun moved across the bodyside and exposed a highlight that wandered. A surface that looked resolved under studio spots fell apart at the wrong hour of the afternoon. Standing bodies cast real shadows; a chief could crouch, tilt his head, catch the car at the height of a five-year-old. The powerwall renders a chosen light. The CAVE renders a chosen environment. Every condition on that wall was authored by someone, which means every condition can flatter. The render is never neutral, and a review that runs on flattering conditions tends to produce confident, wrong decisions.
The second problem is consensus. When forty people review the same wall across four time zones, the review feels democratic and complete. It is neither. More eyes on a screen do not add up to better judgment — they add up to faster agreement, and faster agreement on a surface that nobody has felt in real reflected light is exactly how a flaw ships. The courtyard had a forcing function: physical presence made disagreement expensive and specific. The wall makes agreement cheap.
This is the gap the studios crossing into virtual review are now standing in, and it is the gap worth being honest about. The powerwall solves distribution, speed, and cost — genuinely, and there is no going back. It does not solve the thing those were always in service of: knowing the surface is right before the die is cut. That decision still needs an instrument that tells you what the form does under conditions you did not choose, not just under the one you rendered.
That is the discipline DEPIX builds around. The concept phase doesn't get better because the review is faster or more global; it gets better when the team can put every option in front of the decision under varied, photoreal, honest light — and see which one survives conditions it wasn't flattered by. The wall moved the review across the planet. The hard part — the judgment — stayed exactly where it always was. The studios that win the next decade will be the ones that don't mistake a global review for a good one.
