Nissan is jumping on the lightweight bandwagon by announcing plans to expand their use of high tensile strength steel starting in 2017.
The company will use a newly developed 1.2 gigapascal (GPa) ultra high tensile strength steel which recently debuted on the Infiniti Q50. While the Q50 has some high tensile strength steel components, Nissan plans to increase its usage to represent up to 25 percent of a vehicle's overall weight. This could result in weight reductions of up to 15 percent which would greatly improve fuel efficiency.
Despite being more complex than traditional materials, the high tensile strength steel will lower production costs because less material is needed to build a vehicle.
