Why Automotive Chassis Design for Weight Reduction is Important?

Weight reduction is a priority across automotive industry today. As new regulations and industry standards push towards achieving increased vehicle efficiency and minimizing carbon footprint, it has become imperative for auto manufacturing companies to create designs that minimize weight of the vehicle.

From minutest fasteners to complete vehicle architectures, modern automotive chassis design for weight reduction focus primarily on wringing out additional weight from new systems and components. At the same time, auto manufacturers are looking for innovative ways of lightening the existing vehicle designs, thus, complying with industry standards and regulations, while playing a key role towards sustainable development.

What are the Key Drivers Facilitating Automotive Weight Reduction?
The benefits and motivations for automotive weight reduction are abundant, though a number of barriers also exist. Typically, the key driving factors behind switching to modern automotive chassis design for weight reduction are discussed herewith:
  • Government regulations – In most countries, auto manufacturers have to comply with strict government regulations pertaining to light-weight vehicle chassis. As the regulations are becoming more stringent, more and more manufacturers to switching to automotive weight reduction.
  • Fuel economy and minimizing CO2 emissions – One of the most important reasons behind shifting to weight-reducing vehicle designs is achieving fuel economy and minimizing harmful CO2 emissions. Lighter the vehicle chassis is, better it contributes to fuel economy by delivering smooth performance. At the same time, CO2 emissions can be reduced dramatically with light-weight designs.
  • Consumer behavior – Of late, more and more consumers are demonstrating a changing behavior towards lightweight vehicles, which come with significant benefits and a great value for money. Considering this changing consumer behavior, auto manufacturers are moving towards automotive chassis design for weight reduction.
  • Vehicle safety – With lightweight chassis, safety of the vehicle increases considerably. And this is one important factor that has contributed towards changing consumer behavior and intensity towards manufacturing lightweight vehicles.
  • Cost benefits – Manufacturing lightweight chassis, but with the superior safety guarantee ensures significant cost savings for both manufacturers and buyers.
