The automotive lightweight material market is expected to grow substantially. By 2025, the lightweight material market is expected to grow to an astonishing $99.3 billion in value due to its increasing demand. To give perspective, it is currently valued at $69.7 billion.
Aluminum is already the most demanded automotive material. It is used to replace steel, and in turn, drastically lower the weight of the car. The light-weighting of the car is not limited to its structures. Methods and materials for reducing the powertrain weight are also heavily researched and developed. The powertrain does account for 27% of a vehicle’s overall weight, so making it lighter would add great value in terms of drivetrain efficiency and vehicle dynamics.
Research and development is also being done for acoustic materials which are types of materials such as but not limited to fiberglass and plastics. Although, they probably would not be able to be the majority material of any powertrain any time soon, they will easily decrease the weight of vehicle structures.
With the development of these materials also comes the development of manufacturing processes that are unique to them. As with every form of manufacturing, the efficiency and reusability of excess materials is heavily researched.
Auto Trendy’s take:
Out of all the trends discussed on Auto Trendy, the lightweight trend is the most certain one. It can’t be known when autonomous vehicles will take over, but based on cars that are currently being released, it is easy to see the emphasis on weight-saving.
