INFINITI Breaks New Ground With New SHF Steel Body Frame

INFINITI is the first auto manufacturer to use SHF (Super high Formability) 980 MPa high-tensile steel for automotive use. The new 2019 INFINITI QX50 will be the first vehicle with a body structure containing this remarkably adaptive steel.

The high-tensile material can be molded into unprecedented shapes, saving weight and increasing torsional rigidity by 23 percent over the current QX50 model. As a result, the body structure of the new 2019 QX50 will be able to resist flex and vibrations, while reducing the noise transmitted to the cabin.

2019 INFINITI QX50 Construction

The high rigidity body not only reduces flex and body vibrations but provides a stable base for the all-new QX50’s front and rear suspension systems, steering and brakes to perform optimally and provide the driver with greater control.

Construction of the new 2019 INFINITI QX50 includes varying strengths of steel throughout the body. The strongest, SHF 980 MPa steel is used around the crash zones at the front and rear of the car, to better absorb energy in the event of a collision. Weight-bearing sections around the engine bay and other key structural parts of the car, such as the B-pillar are also made from SHF 980 MPa steel. The vehicle’s cabin is reinforced with 1.2 GPa steel and high tensile steel is used throughout the rest of the bodyshell.

By crafting this unprecedented new body structure and utilizing high tensile steel for automotive use, INFINITI has raised the bar for future automotive construction. Our INFINITI Dealership is pleased to offer vehicles that have been built with unparalleled innovation. We are always pleased to bring you updates on INFINITI vehicles and answer any of your questions.
