Aluminum Lightweighting Dramatically Enhances Performance, Safety and Design
Novelis provides lightweight material solutions for automakers around the world. As both consumers and the industry work to curb CO2 emissions, providing lightweight solutions has never been more of a competitive advantage for automakers.
Vehicles made with aluminum are not only an estimated 40 percent lighter than those made with steel, but they also are safer and more durable. Pound for pound, aluminum can absorb twice as much energy as other materials. In the event of a crash, aluminum components fold predictably to absorb impact before the crash affects the passenger compartment. Lightweight vehicles also require shorter stopping distances than heavier vehicles, helping drivers avoid accidents. According to the U.S. Aluminum Association, every aluminum-bodied car or truck ever crash tested by U.S. federal regulators has earned a perfect 5-star safety rating.
Complementing safety benefits, vehicles made with aluminum consistently meet fuel economy emissions standards. Studies have shown that using 100 kg of aluminum in a car can reduce CO2 emissions by up to eight grams per kilometer traveled.
Emission reductions not only benefit traditional passenger vehicles, but also the next generation of electric vehicles (EVs). A 2016 World Energy Council study reports that by 2020, one in every six cars sold will be electric to meet evolving fuel economy standards. Using Novelis aluminum can reduce EV weight by 20 percent, allowing them to run further on a single charge, which helps reduce range anxiety – the top customer purchase barrier for EVs. Our engineers also work closely with EV designers to transform vehicle layout, battery size, shape and placement.
Today’s consumer not only demands safety and efficiency, they also expect top performance. From mixed-material solutions to aluminum-intensive vehicles, reducing weight by using aluminum enables the use of small, yet powerful, turbocharged engines and fuel efficient, multi-speed transmissions. Vehicles made with Novelis aluminum are lighter weight, resulting in better fuel efficiency, more maneuverability, increased stopping power, quicker response and often increased towing capacity.
Whether focused on traditional passenger vehicles or EVs, our lightweighting capabilities give automakers greater design freedom without being encumbered by material flexibility limitations.
