Eight of the 10 best engines on vehicles sold in North America rely on DuPont materials to help improve fuel economy without compromising performance.

The event celebrating the 10 Best Engines sold in North America is held during the North American International Auto Show, where more than 35 new vehicle models from nearly every global automaker were introduced. Hosted by leading publication Wards Auto, this year’s event was attended by a record-breaking crowd of nearly 600 engineers and management.

“The breadth of materials and the depth of our experienced development teams really set us apart in this industry,” said Chris Murphy, newly appointed to lead the ‘One DuPont’ global automotive industry leadership team. “Our true value is realized when we can bring the whole DuPont portfolio together to help work through tough challenges.”

DuPont materials are used in a wide range of engine system components, including engine covers, air induction and thermal systems, seals, electronic controls and connectors, thrust washers and bearings. The portfolio includes high-performance plastics such as Zytel® nylon, Hytrel® TPC/ET; aramids such as Kevlar®, Nomex®; elastomers such as Viton® and Vamac®; Vespel® parts; Krytox® lubricants, fluoropolymers and microcircuit materials.

Turbo-charged engines dominated the winners list with many of the automakers highlighting that they are now achieving 8-cylinder performance from power-boosted 4-cylinder engines.

“It’s a race to win the hearts and minds of the consumer in a very crowded marketplace,” said Murphy. “These days, the ones who deliver performance and fuel economy are winning.”

As the editors of Ward’s pointed out, “Having a top engine won't redeem a terrible car — but it's a requirement for building a great vehicle.”
