Engine Efficiency for Lower CO2

Engine Efficiency for Lower CO2

DuPont is working with automakers to develop materials that help optimize engine efficiency. Focus areas include heat and friction management, exhaust gas recirculation, and re-imagining turbocharger technology or injection systems for mainstream vehicle production.

Committed to Sustainable Mobility

Committed to Sustainable Mobility

DuPont is working with our auto industry collaborators to help them develop the next generation of sustainable mobility solutions. Together, we’re helping reduce dependence on fossil fuels and lower greenhouse gas emissions to help manage the environmental impact associated with the world’s increasing demand for automotive mobility.

High Performance Materials

High Performance Materials

Many of today’s vehicle system environments are like a pressure cooker of aggressive chemicals. Very few materials have the right combination of characteristics to withstand that kind of severe treatment. DuPont is at the forefront of the development of the latest generation of high performance materials.

Vehicle Weight Reduction

Vehicle Weight Reduction

Vehicle weight reduction is a major challenge. While plastics are inherently lighter than metals, lightweighting requires more than direct material substitution. DuPont predictive engineering and design teams work with customers, using insight and high-performance DuPont materials to redesign for lower weight, often integrating functions to cut costs at the same time.

Meeting a Baffling Design Challenge

Meeting a Baffling Design Challenge

An integrated baffle and seal lip assembly, made of DuPont™ Hytrel® thermoplastic polyester elastomer, is used in two new transmissions from General Motors. The unique solution helps condense packaging space and enable better clutch and transmission durability.

Innovative Ideas for Metal Replacement

Innovative Ideas for Metal Replacement

DuPont collaborates with customers worldwide to develop innovative metal replacement applications to make cars, planes and other equipment more fuel- and cost-efficient.

Supporting Sustainable Mobility

Supporting Sustainable Mobility

DuPont supports efforts/initiatives to improve sustainability in the automotive industry with high performance and renewably-sourced polymers that can help increase fuel efficiency while reducing energy loss, emissions and costs.
