Who Will Win the Lightweight Vehicle Transition?

Car and truck makers are looking to produce lighter vehicles. While they've traditionally used mostly steel, delivered by firms such as U.S. Steel, less weighty aluminum or advanced composites, supplied by companies like Alcoa and Hexcel Corp., are increasingly being employed. Which material provider will win the lightweight vehicle transition?

Auto and truck manufacturers are searching for ways to lighten their vehicles, hoping to improve performance and boost fuel economy. That's good news for aluminum producer Alcoa (NYSE:AA) and carbon-fiber composite developer Hexcel Corporation (NYSE:HXL), which can offer automakers sufficiently strong and lighter weight product. But traditional suppliers, like steel producer United States Steel (NYSE:X), refuse to give up market share easily. They are developing their own less weighty alternative. Which company will win in the transition to lighter weight vehicles?

Aluminum leading the change
Auto giant Ford made headlines when it announced that the next generation Ford F-150 pickup truck would be mostly aluminum. While using the advanced material reduces truck weight by about 700 pounds and thus greatly improves fuel economy, making such a significant change to the nation's most popular vehicle is a bold step. The car and truck maker apparently believes aluminum's advantages are worth the risk of a customer backlash. Furthering the metal's leading position in lightweight vehicles, Ford also introduced an aluminum-intensive concept version of its Fusion automobile. The potential car of the future comes in nearly 25% lighter than a standard steel-based model.

Aluminum is also gaining in large commercial vehicles. Leading aluminum producer Alcoa has developed the world's lightest heavy-duty truck wheel. This innovation, called the Ultra ONE, allows large-truck fleets to increase payloads and gain fuel efficiency. The new wheel, which is 47% lighter than traditional steel, helps boost truck profitability by saving up to 1,400 pounds per rig.

Alcoa aims to take full advantage of aluminum's success in transportation. The company is transitioning from a commodity-based supplier to a value-added product producer. Its $300 million auto product plant expansion in Iowa and doubling of wheel production in Hungary, while closing an Australian can sheet rolling mill and continually reducing smelting capacity, seem to show where the company believes its future lies.

Investors appear to appreciate Alcoa's strategy. The company's stock is up about 40% over the last six months and has jumped nearly 70% over the past two years. Though still down roughly 18% from a 5-year high achieved in 2011, gaining greater auto industry market share could help Alcoa test that share price historical peak.

Composites on the horizon
If the airline industry is any guide, aluminum may be facing some competition, however. Boeing's latest 787 airliner is made of mostly composite materials, a significant change from earlier aluminum-heavy plane designs. The 787 body, nearly 50% comprised of carbon fiber reinforced plastic and other composites, delivers a nearly 20% weight savings when compared to more conventional aluminum construction.

Composites are also making their way into on-road vehicles. Luxury automaker BMW's i3 electric car is a leader in using composite carbon fiber. While no other carmaker has embraced the advanced material as aggressively as BMW, rivals like Audi have mixed and matched aluminum and carbon fiber and Ford utilizes composites in certain areas of its lightweight concept car.

Hexcel Corporation would certainly profit from increased composite use in vehicles. Hexcel, a world leader in carbon fiber for commercial and defense aircraft, has benefited greatly from the aerospace composite boom. Latest quarterly sales grew nearly 11% year-over-year and earnings per share jumped 16%. Since the company supplies both leading aircraft makers, Boeing and Airbus, its increasing backlog suggests strong sales growth should continue in coming years.

Wall Street appears well aware of Hexcel's optimistic future. The company's shares are near a 52-week high and are up nearly 60% over the last two years. With aerospace gains possibly fully factored in, a new catalyst, like meaningful vehicle construction opportunities, may be what's needed to propel Hexcel stock to a higher plateau.

Where does that leave steel?
Steel producers appear severely threatened by advanced material incursion into car and truck manufacturing. But they are fighting back. United States Steel has invested $400 million in a joint venture with Japan's Kobe Steel to develop a lighter high-strength alternative to aluminum or carbon fiber. This improved metal may help enhance steel's current advantages. High-volume automobile manufacturers can't help but notice aluminum 's comparatively higher price and composites are even more expensive. Higher repair and insurance costs for advanced material-based vehicles also tend to guide car makers toward steel.

U.S. Steel has a lot at stake in the lightweight vehicle transition. Flat-rolled steel, an automotive industry staple, made up 67% of company sales and 33% of income last year. In its latest quarter, U.S. Steel reported a profit of $52 million compared to an adjusted net loss of $51 million a year earlier, mainly due to healthy flat-rolled demand. The product's pricing strength, aided by vibrant auto and construction markets, helped the business segment deliver an $85 million quarterly profit even as shipments were stymied by a harsh winter.

Strong auto industry demand has helped U.S. Steel shares climb over 25% in the past two years, but investors seem understandably skittish about the company's future. Worries about advanced material gains have likely contributed to the stock's 10% decline over the last six months. For shares to advance further, it would appear critical that U.S. Steel at least hold its vehicle market share.

Bottom line
As automakers look to produce lighter weight vehicles, traditional suppliers like U.S. Steel could face increasing competition from aluminum producers like Alcoa and composite makers like Hexcel. While aluminum appears the material of choice currently, composites like carbon fiber or improved lightweight steel cannot be ruled out as viable alternatives in a lighter vehicle future. Which company will profit most from this car and truck transition? It's not clear at the moment, but investors may want to watch developments closely. Gains and losses for those involved in the transformation could be significant.

1 Key Step to Get Rich

Our mission at The Motley Fool is to help the world invest better. Whether that’s helping people overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we can help.

Feb 1, 2016 at 4:54PM

To be perfectly clear, this is not a get-rich action that my Foolish colleagues and I came up with. But we wouldn't argue with the approach.

A 2015 Business Insider article titled, "11 websites to bookmark if you want to get rich" rated The Motley Fool as the #1 place online to get smarter about investing.

"The Motley Fool aims to build a strong investment community, which it does by providing a variety of resources: the website, books, a newspaper column, a radio [show], and [newsletters]," wrote (the clearly insightful and talented) money reporter Kathleen Elkins. "This site has something for every type of investor, from basic lessons for beginners to investing commentary on mutual funds, stock sectors, and value for the more advanced."

Our mission at The Motley Fool is to help the world invest better, so it's nice to receive that kind of recognition. It lets us know we're doing our job.

Whether that's helping the entirely uninitiated overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we want to provide our readers with a boost to the next step on their journey to financial independence.

Articles and beyond

As Business Insider wrote, there are a number of resources available from the Fool for investors of all levels and styles.

In addition to the dozens of free articles we publish every day on our website, I want to highlight two must-see spots in your tour of fool.com.

For the beginning investor

Investing can seem like a Big Deal to those who have yet to buy their first stock. Many investment professionals try to infuse the conversation with jargon in order to deter individual investors from tackling it on their own (and to justify their often sky-high fees).

But the individual investor can beat the market. The real secret to investing is that it doesn't take tons of money, endless hours, or super-secret formulas that only experts possess.

That's why we created a best-selling guide that walks investors-to-be through everything they need to know to get started. And because we're so dedicated to our mission, we've made that available for free.

If you're just starting out (or want to help out someone who is), go to www.fool.com/beginners, drop in your email address, and you'll be able to instantly access the quick-read guide ... for free.

For the listener

Whether it's on the stationary exercise bike or during my daily commute, I spend a lot of time going nowhere. But I've found a way to make that time benefit me.

The Motley Fool offers five podcasts that I refer to as "binge-worthy financial information."

Motley Fool Money features a team of our analysts discussing the week's top business and investing stories, interviews, and an inside look at the stocks on our radar. It's also featured on several dozen radio stations across the country.

The hosts of Motley Fool Answers challenge the conventional wisdom on life's biggest financial issues to reveal what you really need to know to make smart money moves.

David Gardner, co-founder of The Motley Fool, is among the most respected and trusted sources on investing. And he's the host of Rule Breaker Investing, in which he shares his insights into today's most innovative and disruptive companies ... and how to profit from them.

Market Foolery is our daily look at stocks in the news, as well as the top business and investing stories.

And Industry Focus offers a deeper dive into a specific industry and the stories making headlines. Healthcare, technology, energy, consumer goods, and other industries take turns in the spotlight.

They're all informative, entertaining, and eminently listenable ... and I don't say that simply because the hosts all sit within a Nerf-gun shot of my desk. Rule Breaker Investing and Answers contain timeless advice, so you might want to go back to the beginning with those. The other three take their cues from the market, so you'll want to listen to the most recent first. All are available at www.fool.com/podcasts.

But wait, there's more

The book and the podcasts – both free ... both awesome – also come with an ongoing benefit. If you download the book, or if you enter your email address in the magical box at the podcasts page, you'll get ongoing market coverage sent straight to your inbox.

Investor Insights is valuable and enjoyable coverage of everything from macroeconomic events to investing strategies to our analyst's travels around the world to find the next big thing. Also free.
