‘Less Means More’: Plastics Delivers More Value through Light-weight Automotive Components

This two minute documentary follows a taxi driver in Wuhu, China. He describes the superior handling and low operating costs of his taxi, thanks in part to collaboration between DuPont and Chery.

Light-weight Automotive Components 

When you talk with someone like Cao Tieniu, the years of materials engineering, application development and processing breakthroughs that go into converting metal automotive components to lighter weight plastic translates to one thing – more profit enabling more time to spend with his family.

Cao Tieniu is the taxi driver featured in this video – Less Means More. He drives a Chery taxi in Wuhu, China.  “Compared to some cars, it uses less fuel,” he says. “For those of us who drive taxis, it increases our profits.”

Designing for lighter weight vehicles

DuPont has been leading the metals to plastics conversion for more than 60 years, working collaboratively with global automakers and the value chain to be the first to bring high volume thermoplastic solutions that reduce weight and cost. 

Today the collaboration model extends beyond powertrain, beyond geographic borders to touch commercial vehicles that move tons of freight cost effectively to scooters where weight reduction can cut curb weight almost in half.

In addition to fuel savings, use of thermoplastic reduces CO2 emissions and offers significant integration opportunities. 

Working with Chery Automobile

The Chery taxi featured in this mini-documentary uses several DuPont advanced materials, including DuPont™ Zytel® nylon resin and DuPont™ Vamac® ethylene acrylic elastomer in components ranging from the air-intake manifold and cylinder head cover to air ducts.

Together the components account for about 30-40 percent decrease in component weight compared with their metal counterpart, generating a significant increase in fuel economy and reduction in CO2 emissions.

“Lightweighting technology is a very important component in the process of fuel efficiency,” said Chen Anning, vice president, Chery Automobile.  “There has been a lot of cooperation between DuPont and Chery.”

Collaboration is essential in bringing science-based solutions to market

DuPont recognizes that no one person, no one company can manage the magnitude of change that industry today faces on their own and has stepped up by creating ”Innovation Centers” that connect 95,000 DuPont scientists to customers and others around the world.

“We’re in an industry where the clock speed is faster and faster and the only way to bring innovation to market is to lay more of our cards on the table,” said DuPont Chief Innovation Officer Tom Connelly. “We need to be more open and transparent about our capabilities and advanced materials solutions as a means of inviting rich conversations about customer and consumer needs.  Then we need to get busy about getting there in the fastest amount of time possible.”
