Chinese car manufacturers indeed bring new cars to market much faster than most traditional global concerns. While a familiar model range is still establishing itself in the market, new cars are already replacing it. And this applies not only to Chinese companies: a similar approach is characteristic of many young car manufacturers that emerged during the electric mobility boom.
As a result, the car development times for these companies have effectively halved. While for traditional manufacturers – from VAZ to Toyota – it is considered normal to create a new model in 40–50 months, and sometimes even longer, in China, such a pace is already considered too slow. Many local companies have learned to go from concept to mass production in approximately 24 months.
This conclusion was reached by a group of McKinsey analysts. It is the high speed of development, among other things, that helps Chinese companies be among the first to implement various new technologies, including sodium-ion batteries and artificial intelligence.
Accelerated development also provides a direct economic effect: reducing timelines allows for lower car creation costs. This partly explains why Chinese cars are, on average, cheaper than their European, Japanese, and American counterparts.
Here are the methods that allow Chinese manufacturers to go from idea to finished car so quickly:
Compact Model Range
Time savings — 1–3 months.
Only a few Chinese companies produce almost everything – from trucks to small cars. This usually refers to state-owned automotive concerns. A large number of models complicates the product structure and slows down development, so younger companies prefer to limit themselves to compact lineups.
Good examples are Voyah and Li Auto, which have only 3–4 models each. Simplification applies not only to the number of cars. Manufacturers strive to use standard components and modular units as widely as possible, which can be installed on different cars without significant design rework.
Virtual Testing Instead of Partial Physical Tests
Time savings — 9–11 months.
Creating physical prototypes and their subsequent testing on test benches requires a lot of time and money. Computer modeling and various types of simulation have long been used by the automotive industry, but Chinese companies apply these methods more actively.
Virtual testing accounts for approximately 65% of all checks. On average, across the automotive industry, this figure is only 40–50%.
Separation of Software and Hardware
Time savings — 3–10 months.
Tesla was the first to master this approach, after which Chinese car manufacturers quickly adopted this practice. Cars use centralized digital architectures that allow software to be developed independently of the hardware.
In addition, over-the-air updates make it possible to fix software problems after the car has been sold. The downside of this approach is also obvious: frequent software errors in Chinese cars are a consequence of the high speed of development.
Production Preparation Begins During Development
Time savings — 1–4 months.
Virtual design allows the most complex production tooling to be manufactured even before the car's development is fully completed. This refers, in particular, to molds and dies.
For the manufacture of plastic parts during the testing phase, so-called "soft" tooling can be used. Unlike conventional tooling, it is made of polymers, not metal.
Vertical Integration
Time savings — 3–4 months.
Many Chinese car manufacturers strive to independently control the development of a significant part of components and systems. These include batteries, electric motors, and transmissions.
This approach simplifies and accelerates design: various units are easier to coordinate with each other when their development is under the control of one company.
Western manufacturers have a different model – outsourcing the development and production of individual components to specialized suppliers, such as ZF or Getrag. This solution has its advantage: the car concern can always choose the most profitable offer. However, car development in this case takes more time.
Strict Project Management
Time savings — 1–3 months.
In young Chinese companies, the management structure is usually as compact as possible. Often, key decisions are made by a small team of 4–5 top managers. Several times a week, they hold short meetings to discuss project progress and promptly determine further actions.
Digital project management systems with AI analytics and generative models become an additional tool. Such systems are capable not only of automatically reminding employees of approaching deadlines but also of independently detecting potential risks and problems.
The Downside of Accelerated Development
The slow pace of traditional car manufacturers did not appear by chance. New models are not just created longer – they often remain in production for 7–10 years. During this time, the enterprise manages to stabilize production, eliminate identified defects, and fully recoup the costs of preparing production and manufacturing tooling.
As a result, the buyer receives a refined product, and the manufacturer gets the opportunity to provide full service support.
When the life cycle of new models is reduced to 2–5 years, the situation changes. All project participants have to work under constant pressure and high speed, which increases the likelihood of errors.
The accelerated approach also has another feature: new cars can become too similar to previous models, gradually flowing from one generation to another. Creating a truly distinctive car takes time, and with maximum compressed development times, there is practically none left.
Perhaps this is why some Chinese cars give the impression of being rather faceless machines: at such a pace, it is simply more difficult for engineers to infuse individuality into a new project.
