Heavyweights No More: Lightweighting SUVs and Trucks with U. S. Steel
by Jim Bruno, Senior VP
February 27, 2025
For Americans, less is not always more—especially when it comes to vehicles. In 2024, more than 80 percent of new car sales in the United States were for SUVs and trucks. That represents a significant rise from 2010 when they made up just half of new vehicle purchases. This shift reflects a deep-seated preference for size, power, and capability.
But there’s a catch. While Americans love big cars, they also want to save money at the pump. Traditionally, that’s been a tough balancing act—larger vehicles typically mean heavier weight, which translates to lower fuel efficiency. After all, physics dictates that moving more mass requires more energy.
What If Bigger Didn’t Mean Heavier?
Imagine a world where drivers don’t have to choose between size and efficiency. A world where trucks and SUVs retain their power and capability—but with significantly improved fuel economy. Sounds too good to be true.
It’s not.
Enter U. S. Steel.
The Power of XG3 Ultra High-Strength Steel
As a leader in advanced high-strength auto steels, U. S. Steel is redefining what’s possible for the automotive industry. Our XG3™ advanced high-strength steel allows automakers to design vehicles that are stronger, lighter, and more fuel-efficient—without sacrificing safety or durability.
And we’re not just supplying steel—we’re working hand-in-hand with automakers to develop innovative solutions that fit their exact needs. As the only steelmaker with a dedicated auto center in the Motor City, we’re uniquely positioned to collaborate directly with leading manufacturers, helping to shape the future of American trucks and SUVs.
Proof on the Road: Stronger, Lighter Trucks and SUVs
At the Detroit Auto Show last month, our team took a close look at some of the latest models that showcase the advantages of advanced lightweight steel. These vehicles demonstrate how the next generation of trucks and SUVs are being designed with strength, efficiency, and performance in mind:
Toyota Tacoma – A legendary midsize truck, now featuring lighter, stronger materials for improved efficiency.
Jeep Gladiator – Built for adventure, with high-strength steel delivering off-road capability and durability.
Chevy Silverado – The perfect tailgating vehicle, as two USS auto experts demonstrate during a conversation about Detroit and its legacy of automaking excellence.

The Road Ahead
As consumer demand for larger, more fuel-efficient vehicles continues to grow, U. S. Steel remains at the forefront of innovation. By pushing the boundaries of steel technology, we’re ensuring that American drivers no longer have to compromise between size and efficiency.
Because when it comes to the future of trucks and SUVs, more can finally mean less—less weight, less fuel consumption, and less compromise. Maybe less is more after all!

forward-looking statements to be covered by the safe harbor
provisions for forward-looking statements in those
sections. Generally, we have identified such
forward-looking statements by using the words "believe,"
"expect," "intend," "estimate," "anticipate," "project,"
"target," "forecast," "aim," "should," "will," "may" and
similar expressions or by using future dates in connection
with any discussion of, among other things, the
construction or operation of new or existing facilities or
operating capabilities, the timing, size and form of share
repurchase transactions, operating or financial
performance, trends, events or developments that we expect
or anticipate will occur in the future, statements relating
to volume changes, share of sales and earnings per share
changes, anticipated cost savings, potential capital and
operational cash improvements, changes in the global

international trade policy, statements regarding our future
strategies, products and innovations, statements regarding
our greenhouse gas emissions reduction goals, statements
regarding existing or new regulations and statements

However, the absence of these words or similar expressions
does not mean that a statement is not forward-looking.
Forward-looking statements are not historical facts, but
instead represent only the Company's beliefs regarding
future events, many of which, by their nature, are
inherently uncertain and outside of the Company's control.
It is possible that the Company's actual results may
differ, possibly materially, from the anticipated results
indicated in these forward-looking statements. Management
believes that these forward-looking statements are
reasonable as of the time made. However, caution should be
taken not to place undue reliance on any such
forward-looking statements because such statements speak
only as of the date when made. Our Company undertakes no
obligation to publicly update or revise any forward-looking
statements, whether as a result of new information, future
events or otherwise, except as required by law. In
addition, forward-looking statements are subject to certain
risks and uncertainties that could cause actual results to
differ materially from our Company's historical experience
