Build or Buy? Automakers Chasing Tesla Rethink Dependence on Suppliers

Automakers racing to develop battery-powered, software-driven vehicles to compete with Tesla are confronting a new challenge: what technology to build themselves, and what to keep buying from suppliers.

Becoming more vertically integrated by doing more manufacturing in-house represents a major shift for most global automakers, who have relied for decades on suppliers to produce critical parts and software, and manage sprawling manufacturing networks in low-wage countries.

But some established automakers are embracing drastic changes to their longstanding build-or-buy calculations. One factor is the success of Tesla's electric vehicles, which rely on proprietary technology the company develops and manufactures itself. Another is the financial damage done by supply-chain breakdowns during the pandemic.

"The most important thing is we vertically integrate. Henry Ford ... was right," Ford Motor's CEO, Jim Farley, said at a conference in earlier this month. Farley's reference was to company founder Henry Ford's Rouge manufacturing complex in Dearborn, Michigan, which in the early 20th Century took in iron ore and other raw materials at one end, and churned Model Ts off the assembly line at the other.

Farley said the company had to move away from its early EV strategy of buying components off the shelf. Now, he said, Ford aims to control the supply chains "all the way back to the mines" that produce battery materials.

Rivals including Volkswagen, General Motors, and Mercedes-Benz are pursuing similar strategies. Mercedes last year acquired British high-performance electric motor manufacturer YASA, and has retooled a factory near Berlin to produce motors based on YASA technology. The German luxury car maker in March opened a new factory in Alabama to build battery packs for U.S.-made electric vehicles, and said it will partner with Japanese battery maker Envision AESC to build battery cells in the United States.

"We are going deep into sourcing," Mercedes-Benz Chief Executive Ola Kaellenius told reporters during a briefing in Alabama.

Winning strategy

The investments by automakers in mines, motors, and batteries are a departure from decades of handing control over development and production to suppliers, who could produce steering controls, semiconductors and electronic components at greater scale and lower cost for multiple vehicle manufacturers.

In the new world of electric vehicles, however, investors have decided that Tesla's approach of buying raw materials directly, building its own batteries and engineering its own software is the winning strategy. Tesla's market capitalisation has soared back above $1 trillion (roughly Rs. 76,11,280 crore) in recent weeks, outweighing that of Toyota, Volkswagen, GM, and Ford combined.

"Major players have realised electric vehicles are the future, but they have yet to widely recognize that they have to up their game in terms of motors, transmissions, battery technologies, inverters and electric powertrains," Peter Rawlinson, CEO of EV startup Lucid, said in an interview with Reuters. Rawlinson previously was vice president of vehicle engineering at Tesla.

Between the 1970s and the 2010s, the share of automaker-owned intellectual property in their vehicles decreased from 90 percent to 50 percent, according to Guidehouse Insights analyst Sam Abuelsamid.

That meant many automakers lacked the in-house engineering expertise to develop their own electric vehicle platforms, powertrains and battery packs when EV pioneer Tesla showed its vertically integrated cars were a hit with consumers.

"We're designing and building so much more of the car than other OEMs who will largely go to the traditional supply base and [execute] like I call it, catalog engineering," Tesla CEO Elon Musk said during a 2020 earnings call.

Tesla's approach is costly and the company has raised vehicle prices repeatedly in the last few years. Despite promising to deliver a model that could start at about $25,000 (roughly Rs. 19 lakh), Musk earlier this year said "we're not currently working on the $25,000 (roughly Rs. 19 lakh) car. At some point, we will. But we have enough on our plate right now."

Technology race

There is also a gap between what automakers say about their vertical integration strategies, and what happens as engineers try to meet deadlines to deliver new vehicles, supplier industry executives said.

"There's a lot of narrative about in-sourcing and vertically integrating, especially in areas like software," Kevin Clark, chief executive of auto supplier Aptiv, told analysts in February. "Virtually all the OEMs that we are doing business with are struggling with software development."

Xavier Mosquet, a senior adviser at Boston Consulting Group, said many manufacturers still prefer to buy EV technology to avoid the cost and complexity of manufacturing in-house.

"There are a number of automakers who in a way want to continue buying and manage the final integration," Mosquet said, adding that it would take several years to determine which approach is successful.

Many automakers are also hesitant to completely in-source EV manufacturing at a time when EV purchases still make up only a fraction of total vehicle demand.

Today, only Tesla, EV startup Lucid Group, and Chinese BYD are completely making their electric motors in-house, according to IHS Markit, followed by Hyundai Motor and the Renault-Nissan-Mitsubishi alliance.

Other carmakers, including Mercedes-Benz Group, Ford, and Porsche, are using electric motors by suppliers for their current EV models.

"The electric powertrain cannot be bought off the shelf at a world-class standard, it is not a commodity," Rawlinson said. "This is a technology race and the market doesn't see it yet."

Mercedes said it plans to make electric motors, battery packs, and electronics in-house starting in 2024. The company is also working to reduce costs by securing raw materials directly from miners, Chief Technology Officer Markus Schaefer told Reuters.
