2019 Vehicles—Lighter with AHSS Structures

By on March 22, 2019 in IN THE NEWS

Many 2019 model year vehicles introduced in 2018 have something in common—an advanced high-strength steel (AHSS) structure. More than 65 AHSS-intensive vehicles debuted at major auto shows last year. AHSS was represented in the composition of every vehicle segment and size, including the popular SUV, CUV and truck markets.

“As vehicles evolve to become stronger, safer and more durable, high-strength steel continues to be the material of choice for automakers,” said Dr. Jody N. Hall, vice president, automotive market, Steel Market Development Institute (SMDI). “Occupant protection is enhanced by using high-strength grades of steel in critical vehicle areas such as the frame and body.”

Here’s some notable vehicle debuts that came in with lower weight.

2019 Hyundai Santa Fe (nominated for 2019 North American Utility Vehicle of the Year)
• The body is composed of 67-percent high-strength steel for added strength and reduced weight

2019 Chevrolet Silverado (finalist for 2019 North American Truck of the Year)
• The fully boxed steel frame is 88 pounds lighter than its predecessor, while offering 10-percent greater torsional rigidity
• Eighty percent of the frame is made of high-strength steel

2019 Acura RDX (finalist for 2019 North American Utility Vehicle of the Year)
• The lighter body structure has more than 50-percent high-strength steel, increasing body rigidity and cabin quietness

2019 Jeep Cherokee
• To achieve lightweighting in the body, Jeep used 65-percent hot stamped, high-strength and ultra-high-strength steel

2019 Mercedes-Benz G-class
• Thanks in part to high- and ultra high-strength steels comprising the body, the new model lost 375 pounds
