In global automotive circles, “China speed” has become shorthand for an industrial capability most Western carmakers have yet to master: taking a new model from clean sheet to showroom in just over two years. Chinese automakers now routinely complete full vehicle development in 18 to 24 months, while European and American incumbents typically need twice as long — and some programmes take even longer.
At home, the pace has stirred debate. Geely chairman Li Shufu warned that “pretending to know when you don’t will cause endless trouble”; Beijing Hyundai vice-president Li Fenggang accused some companies of “turning customers into unwitting test drivers”; and Voyah CEO Lu Fang argued that development speed should not be judged by time alone. But while domestic discussion focuses on whether validation steps are being compressed, global automotive data and consulting firm MobilityGlobal offers a different lens: how the supply chain experiences and explains China speed.
Parallel engineering, not hurried work
Most analyses of China speed focus on the carmakers themselves, crediting optimised product-development systems. Suppliers, however, occupy a unique vantage point: they serve multiple projects, clients and regional markets simultaneously, and can see where decisions are made, how information flows, and where time actually disappears. Their frontline experience suggests China speed is not the result of rushed, deadline-driven work but of efficient organisational coordination.
Traditional development systems prize predictability, following a strict stage-gate logic: suppliers get deeply involved only after design is mature, validation begins only after engineering is complete, and manufacturing preparation waits until the design is frozen. Each phase has clear boundaries, with the goal of eliminating uncertainty before the next step. The cost, suppliers say, is accumulated waiting time. Individual decisions may take only days, but months vanish in the gaps between stages and between decisions. Hanno Focken, managing director of automotive data ecosystem Catena-X, has noted that differences in development efficiency stem from how organisations collaborate, not how fast they execute internally.
Chinese carmakers, by contrast, have re-engineered the collaboration. Engineering, purchasing, manufacturing and supply-chain teams work in parallel, and functional boundaries blur: tooling development starts while the design is still iterating; manufacturing engineers weigh in before drawings are final; suppliers are not passive recipients of decisions but deep participants throughout. Suppliers observing both models say the difference is obvious: requirements arrive earlier, designs change more often, prototypes are smaller but more frequent, and engineering change notices have shifted from exception to routine. This approach does not make parts faster, but it handles uncertainty more calmly.
Digital tools and trust as operating assets
These collaboration patterns depend on organisational change. Cross-functional project teams shorten the loop between problem identification and solution, while digital technology reinforces the gains: simulation replaces some physical testing, digital twins reduce reliance on physical prototypes, and artificial intelligence accelerates design exploration and validation.
The impact extends beyond engineering. Earlier supplier involvement forces carmakers to be more transparent: cost discussions start before design decisions are final, and risk is distributed differently through the supply chain. Trust becomes an operating asset — collaboration that begins before all uncertainties are resolved simply cannot run without it.
Western manufacturers are starting to adopt some of these practices. Renault's compressed development programme for the next Twingo and Volkswagen's reorganisation of its engineering operations in China are cited as examples, with validation partners brought in earlier to shorten the feedback loop between testing and engineering. Mike Gardner, executive director of the eSync Alliance, a standard for automotive software updates, says Chinese manufacturers build on the assumption that “a vehicle is never finished,” treating software as a living product rather than a one-time deliverable.
Copying China speed, however, means more than adopting shorter timelines. It demands courage: investing earlier, granting core teams real autonomy, and accepting that Western carmakers selling globally face more fragmented regulation and higher product complexity, making compressed development harder without compromising validation, according to the report.
