Companies to bring together best-in-class solutions for natural gas transportation fuel systems

3M and Rush Enterprises today announce an agreement to pursue the design, manufacture and installation of a portfolio of compressed natural gas (CNG) tanks and fuel systems for use in Class 6-8 vehicles in North America. The Agreement allows for 3M to supply tanks with proprietary technology, and for Rush Enterprises to provide enhanced fuel systems, distribution and service support.

“We believe the lack of a holistic approach to fuel system development has slowed adoption in this segment,” said Rory Yanchek, Vice President and General Manager for 3M’s Aerospace & Commercial Transportation Division. “Our collaboration with Rush Enterprises will help accelerate industry adoption by bringing superior value to customers, and delivering quality solutions that address many currently unmet needs.”

Yanchek continued, “Industry partnerships can address these needs, but they must be built on a foundation of technology, a relentless commitment to quality, and aftermarket support.”

3M launched its first CNG tank in 2013, incorporating its pioneering nanoparticle-enhanced resin technology in order to engineer tanks that are up to 30% lighter and have up to 10% more storage capacity than the market leading Type IV alternative.

“The technological advancements brought forth by 3M in the CNG tank space have been game-changing,” said W.M. “Rusty” Rush, Chairman, Chief Executive Officer and President of Rush Enterprises. “Combining that technology with our ability to provide innovative solutions to the commercial vehicle industry, vehicle integration engineering and installation expertise and a national network of sales and service centers gives us a truly unique offering.”

“By pairing a leading materials/technology company with one of the largest commercial vehicle dealership networks, we hope to achieve scale as well as move the needle in customer service and innovation,” said Mr. Rush. “Working with 3M on a new fuel system and incorporating a diversity of 3M’s proprietary materials to enhance value, as well as leveraging 3M’s expertise in Lean Six Sigma manufacturing processes, is going to improve the overall quality and reliability we bring to customers.”

3M is exhibiting at the Alternative Clean Transportation Expo (ACT), May 5-8, Long Beach, CA, and the companies expect additional announcements later this year. Initial plans for the companies include:

• Introduction of a new line of CNG tanks in North America for Class 6/7/8 vehicles, with the first tank being introduced in late 2014
• Launch of an advanced, lighter weight fuel system incorporating several design and material enhancements that delivers higher quality and reliability in Spring 2015
