Honda, and Magna’s Cosma International have been jointly selected winner of
a 2014 Automotive News PACE Award in the ‘Manufacturing Process and Capital
Equipment’ category, for the industry’s first laser-welded, hot-stamped door
ring in the 2014 Acura MDX.
announced at the 20th annual Automotive News PACE Awards ceremony on April 7
in Detroit. The PACE Awards celebrate automotive suppliers' innovations in
products, manufacturing processes, and information technology.
“We are honored to
receive such significant industry recognition from Automotive News for our
partnership with ArcelorMittal and Magna’s Cosma International to develop
the world’s first ultra-high strength steel, one piece front door stiffner
ring, said James Keller, vice-president, Honda R&D Americas Inc. “This
partnership was integral to achieving our vision of ‘lighter, stronger,
faster’ for the MDX.”
“The door ring
enhances the safety performance of the MDX to meet today’s stringent roof
crush and side impact standards, as well as the rigorous new IIHS small
overlap front crash test,” Keller added.
The door ring
starts at the largest integrated steelmaking operation in North America,
ArcelorMittal Indiana Harbor in East Chicago, with the production of
patented Usibor¨ 1500, an aluminum silicon coated advanced high strength
steel. The Usibor¨ 1500 steel is prepped at an ArcelorMittal joint venture
in Dearborn, Mich., then shipped to ArcelorMittal Tailored Blanks in
Pioneer, Ohio, where the enabling technology for the door ring, called laser
ablation, takes place. After the laser ablation, a quality control process
is done via a high-tech process to ensure precision.
The combination of
Honda’s design, ArcelorMittal’s steel and laser-welded blank technology, and
Cosma’s hot-stamping manufacturing process resulted in a weight reduction of
8.6 pounds on the Acura MDX. Overall, the door ring innovation helps the
2014 Acura MDX (V6, AWD) achieve fuel economy of 18/27 MPG city/highway, an
improvement of two MPG city and six MPG highway over the 2013 model.
