Lightweight Design
Today’s vehicle platforms are shaped by four critical demands: lighter weight, enhanced safety, lower cost, and simplified manufacturing. Achieving the right balance requires engineers and designers to select materials that deliver optimal performance in every application.
The steel industry has risen to this challenge with an expanding portfolio of advanced steel solutions engineered for modern automotive design. Continuous advancements in strength and formability have produced advanced high-strength (AHSS) steel grades with performance characteristics that would have seemed impossible just a decade ago.
With more than 65 advanced AHSS grades available, designers have unprecedented flexibility to optimise vehicle structures. From internal combustion engine (ICE) vehicles to battery electric vehicles (BEVs), AHSS enables reduced material thickness while maintaining, or even improving crash performance, structural stiffness, and long-term durability.
The result is:
- greater design freedom
- weight reduction
- improved efficiency
…and the confidence that comes from building with steel, one of the most versatile materials in automotive manufacturing.
Steel: Engineered for Superior Safety Performance - Without Compromising Lightweight Design
As vehicle safety regulations become increasingly stringent, additional challenges arise – namely, designing vehicles that can absorb significant crash energy while maintaining the rigidity needed to protect occupants, all without adding unnecessary weight.
Advanced high-strength steels help achieve this balance.
Energy-absorbing grades such as Dual-Phase (DP) and Transformation-Induced Plasticity (TRIP) steels are engineered to manage and dissipate crash forces effectively. At the same time, ultra-high-strength materials including Martensitic and Press-Hardened Steel (PHS) provide the structural integrity needed to minimise intrusion into the passenger compartment during a collision.
By strategically combining these types of advanced steel grades throughout the vehicle structure, manufacturers can enhance occupant protection, meet increasingly demanding crash requirements, and reduce vehicle mass without compromising performance.
