Toward Lighter Vehicles
Vehicle weight reduction makes important contributions to improve fuel
efficiency. Nissan is promoting vehicle weight reduction by optimizing
vehicle body structure, developing better forming and joining techniques and
substituting materials. For example, it is reducing the thickness of
components to optimize structure and using lightweight foamed materials
for internal component resins.
Nissan is seeking weight reduction in steel parts and promoting the
use of Advanced High Tensile Strength Steel (AHSS). In fiscal 2013, Nissan
used 1.2 gigapascal (GPa) Ultra High Tensile Strength Steel with High
Formability in its Skyline and Infiniti Q50. In combination with other
measures, this achieved a total weight reduction of about 40 kg. This type of
steel enables considerable weight reduction by remaining strong even when
thin. Its greater elongation through an optimal combination of materials
offers high formability, and it can be used in vehicle parts with highly
complex shapes. Employing 1.2 GPa Ultra High Tensile Strength Steel with
High Formability allows usage of less material per vehicle produced, all
without requiring major modification to existing production lines. This results
in a reduction in total cost per unit. Nissan will expand the use of AHSS up
to 25% of the vehicle parts (measured by weight) installed in its new
production models starting in 2017.
Through these initiatives, in addition to the above two models, the
Altima and three other Nissan models launched in fiscal 2012 and 2013 led
their class for vehicle weight (at time of sale, based on Nissan research)
