China's Two-Year New-Car Development Cycle Raises 'Instant Car' Concerns as Some Automakers Skip Validation

In the first half of 2026, about 165 all-new models are expected to launch in China, compared with fewer than 90 in the same period of 2016. The domestic new-car development cycle has now been shortened from five years in the traditional fuel-vehicle era to two years. Industry data show that the domestic new-car market offers about 3,780 SKUs, while the smartphone industry has 1,240 SKUs and the beverage industry offers about 4,000 SKUs across all categories.

A brand-new vehicle typically requires market research, styling design, technical development, clay modeling, multiple reviews, platform adaptation, component matching, simulation testing, and real-road testing. According to an R&D insider, a normal development process takes at least three years, with both design validation and production validation phases completed. Under current national standards, fuel vehicles must undergo a reliability road test of 30,000 km, while new-energy vehicles require 15,000 km. A revised national standard is expected to raise the new-energy vehicle test mileage to the same level as that of fuel vehicles.

The shortened development cycle is mainly seen in facelift models. Some automakers, using the same platform and identical component suppliers, shorten the process in design and hardware testing. For example, when iterating from the 2026 model to the 2027 model, the platform and battery suppliers remain largely unchanged, and only the front-end design, exterior headlights, or infotainment screen size are altered, reducing the need for repeated validation of similar components. A R&D official at GAC Group said that meeting the 30,000-km road-test requirement does not equate to vehicle safety, and automakers should focus on design flaws and production consistency after mass production begins.

The extent of simulation testing in vehicle development has drawn attention. Some automakers, to cut costs, perform only 20% of tests physically, with the remaining 80% relying on simulation. For instance, one new-energy vehicle maker requires 10,000 door-handle tests, but only 2,000 are physical tests; the rest are simulated. Current national standards only stipulate minimum test mileage for fuel and new-energy vehicles, without specifying a ratio between simulation and real-road testing. Industry insiders say simulation can replicate extreme conditions that are hard to reproduce in real road tests, such as highway collapses or earthquakes, but real-road testing is more expensive. Automakers that increase the the frequency of physical tests when cost and conditions allow can better enhance safety.

The shorter development cycle is also linked to technological progress. Since the 1980s, automotive simulation has been used in fuel-vehicle development and validation. Today, AI technology is applied in battery design, exterior and interior styling, and other areas, using vast data to assist R&D. A McKinsey expert noted that new-energy automakers use high-precision virtual simulation to advance tooling production, introduce soft tooling instead of traditional metal molds during prototyping, and adopt integrated large-scale die-casting to form structural components that previously required dozens of parts welded or assembled in one piece, reducing the total number of molds. Standardized platforms, electronic and electrical architectures, component combinations, and software-hardware decoupling also help automakers optimize the new-car development cycle.

In recent years, regulators have successively issued new mandatory standards for professional automotive areas such as door handles, power battery safety, and autonomous driving.
