This month, Volkswagen, once the proudest symbol of German industrial strength, said it would cut its model lineup by as much as half and, if unions agree, shed up to 100,000 jobs. Days later came a more startling report: XPeng, a Chinese electric vehicle startup barely a decade old, is in talks to buy one of Volkswagen's underperforming European factories.

Read that again. The student is no longer merely outselling the teacher. The student is bidding on the teacher's classroom.

In Washington and Detroit, the reflexive answer is protection. Tariffs on foreign cars and an effective ban on Chinese EVs will, the thinking goes, give General Motors and Ford the breathing room to catch up. That assumption is dangerously incomplete.

Tariffs buy time; they do not buy capability.

The durable strategy is the uncomfortable one: Invite Chinese EV makers into joint ventures on American soil, with technology transfer written into the terms, exactly as Beijing did with American and European automakers four decades ago.

How the Best Customers Became the Fiercest Rivals

Consider how fast fortunes have reversed. When GM entered China in 1997 through a joint venture with state-owned SAIC Motor, crowds lined up outside its Shanghai showroom to glimpse Buicks and Cadillacs.

Today, GM Shanghai is losing millions of dollars a quarter as Tesla, BYD and Geely muscle out its tried-and-true models. SAIC-GM is racing to electrify before the partnership expires. But the backdrop is brutal: Buick, once GM's crown jewel in China, saw sales collapse by roughly 75% from their peak.

Volkswagen's fall is steeper because its bet was bigger. The company arrived in Shanghai in 1984 and led the Chinese market for forty years. At its height, China delivered half or more of Volkswagen's global profits, underwriting generous wages back in Germany. Then came the EV transition. VW's China sales last year were down by a third from 2019, and sales from April through June fell by another third from a year earlier.

Worse, the competition has followed VW home. Chinese automakers passed Japanese brands in European Union market share in May, while Chinese cars pour into Latin America and Africa, markets Volkswagen had long dominated.

Tariffs Are a Tourniquet, Not a Cure

The Trump administration's import tariffs and its wall against Chinese EVs shield Detroit from this onslaught for now. But a tourniquet stops bleeding; it does not heal the wound.

Three structural handicaps remain untouched.

First, automation. The terms the UAW won in 2023 negotiations with the Detroit 3 make aggressive robotics and flexible staffing far harder to deploy, precisely when Chinese plants are setting global benchmarks for speed and cost.

Second, batteries. American battery-cell development and scale still lag the Chinese champions who control most of the world's battery supply chain, and the gap is not closing on its own.

Third, software. U.S.  integration of electronics, connectivity and AI—where Chinese EVs now win customers—is years behind Chinese automakers Shenzhen and Guangzhou. GM and Ford are pushing hybrids and a handful of EVs, but at high prices and with quality questions relative to Japanese and Chinese rivals.

There is a another problem tariffs cannot solve: the rest of the world.

Detroit cannot tariff its way into Brazil, Indonesia or the Gulf. If American EVs are uncompetitive abroad, protection at home simply guarantees a shrinking franchise: comfortable today, irrelevant tomorrow.

We Have Run This Play Before, in Reverse

What critics of engagement miss is that industrial learning flows both ways, and the United States has been on both sides of it. Japan learned carmaking and chipmaking from America, then America learned lean production from Toyota.

 GM's NUMMI joint venture with Toyota in Fremont, launched in 1984, delivered mixed results for GM.  The underlying reason is mostly that GM treated it as a factory rather than a school. But the lesson stands: the fastest way to close a capability gap is to manufacture alongside the leader.

China understood this perfectly. For decades, it required foreign automakers to enter joint ventures and share technology as the price of market access. Foreign executives grumbled and complied because the market was too big to ignore. Chinese partners absorbed the know-how, then leapt ahead when the industry pivoted to electric drivetrains, where legacy engine expertise counted for little.

The reversal is now explicit: Volkswagen has signed a master agreement with XPeng to co-develop electrical and electronic architecture. The world's second-largest carmaker is paying a Chinese startup for core technology.

The asymmetry cuts in America's favor if Washington is willing to trade. BYD and XPeng want access to the world's most profitable car market and production inside the tariff wall. America wants battery chemistry, software stacks and manufacturing methods. Those wants are complementary.

A sensible framework would require majority American ownership, domestic battery supply chains, binding technology transfer, and strict carve-outs on vehicle data and connected-car software to address legitimate security concerns. None of this is naive engagement. It is the same hard-nosed bargain China struck in 1984 with VW and 1997 with GM, with the roles reversed.

The Clock Is the Real Competitor

Skeptics will say Detroit should catch up on its own. Perhaps it can, but the evidence from Wolfsburg suggests the window closes faster than incumbents believe. Volkswagen had scale, capital, brand and four decades of Chinese market intimacy, and it still lost the transition in under five years.

The American government can buy time with tariffs. It cannot buy speed, and speed is what American firms lack.

The strategic choice is therefore not between protection and openness. It is between learning quickly behind the tariff wall or declining slowly behind it.

If Detroit cannot beat its competitors, it should join them—and learn faster than they expect—just as Japan once did and China later did.
