If you walked into a luxury dealership today to buy a new Mercedes-Benz E-Class, you probably wouldn't think twice about where the money goes. You're buying classic German engineering. But lawmakers in Washington see something else entirely when they look at the iconic three-pointed star. They see a vehicle company sitting dangerously close to Beijing.
A Senate bill aimed at shutting out Chinese vehicles from American roads has accidentally put Mercedes-Benz right in the crosshairs. The draft legislation targets connected vehicles—cars loaded with software, cellular data connections, and automated driving systems—produced by automakers with Chinese ownership above 15%.
The catch? Chinese entities own almost 20% of Mercedes-Benz Group AG.
If this bipartisan bill becomes law without major edits, Stuttgart's flagship brand could face a complete sales ban across the United States. That's a staggering reality for an automaker that has built cars in America for nearly three decades.
The 15 Percent Rule Crashing German Engineering
The legislation in question—introduced by Senator Elissa Slotkin of Michigan and Senator Bernie Moreno of Ohio—aims to lock down the domestic market against foreign cyber risks. Lawmakers worry that connected vehicles from strategic rivals could harvest location data, track citizens, or even be disabled remotely.
To address those fears, the proposed rule draws a hard line. Any carmaker with more than a 15% equity stake held directly or indirectly by Chinese entities face an outright ban on selling connected vehicles in the US.
Here's how Mercedes gets trapped by that math:
- BAIC Group: The state-owned Chinese automaker holds a 9.98% equity stake in Mercedes-Benz.
- Li Shufu: The billionaire founder of Geely (which owns Volvo and Lotus) holds a 9.69% stake through investment vehicles.
- Combined Chinese Ownership: 19.67%—well over the 15% ceiling set by Congress.
Mercedes isn't an isolated case, but it's easily the largest casualty. Geely-owned Polestar already saw its US sales derailed after federal regulators rejected its connected vehicle applications, forcing the brand to halt sales once current inventory clears out. Volvo Car AB faces similar scrutiny, though lawmakers are discussing a grandfather clause tied to existing security pacts.
Mercedes enjoys no such blanket exemption under the current draft.
How Two Chinese Shareholders Ended Up Holding 20 Percent of Mercedes
To understand how Stuttgart ended up in this fix, you have to look back at the corporate moves of the late 2010s.
Back in 2018, Geely chairman Li Shufu quietly built up a massive holding in Mercedes, surprising executives and regulators alike. A year later, long-time joint-venture partner BAIC increased its own stake. Both companies saw Mercedes as a prime technology partner for electric vehicles and global scale. Mercedes welcomed the capital, especially as China grew into its largest single market for high-end sedans like the S-Class and Maybach.
At the time, western governments encouraged global auto investment. Nobody predicted Washington would one day treat indirect shareholder equity as an immediate national security risk.
Mercedes maintains that these shareholders don't control daily operations. The company repeatedly emphasizes that neither BAIC nor Li Shufu holds a seat on the supervisory board, nor do they have access to proprietary vehicle software, source code, or consumer data streams. No single Chinese investor holds more than 10% on their own.
Senate hardliners don't seem to care. In Washington's current climate, any financial tie to Beijing is viewed with extreme suspicion.
Alabama Plants and Billions at Stake in Washington
Mercedes isn't taking this sitting down. The automaker has deployed lobbyists to Capitol Hill to push for key changes before the bill makes it to a full floor vote.
The primary change Mercedes wants is simple: bump the ownership cap from 15% to 25%.
That 25% threshold would align the vehicle ban with rules already proposed for supply-chain vendors and component makers. More importantly, it would instantly clear Mercedes, giving it breathing room above its current 19.67% mark.
As an alternative, Mercedes lobbyists are urging lawmakers to dump fixed percentage cutoffs in favor of a qualitative national security risk test. Under a qualitative test, federal agencies would evaluate actual software control and governance structures rather than raw share counts.
Mercedes is leaning heavily on its deep roots in the US economy to make its case:
- Assembly Operations: Mercedes opened its massive plant in Vance, Alabama back in 1997. It also operates a Sprinter van facility in Ladson, South Carolina.
- Local Jobs: The German brand supports roughly 160,000 direct and indirect jobs across American manufacturing, local suppliers, and nationwide dealerships.
- Capital Commitments: Earlier this year, Mercedes pledged another $4 billion toward its Alabama operations to build out electric battery integration and vehicle assembly through 2030.
- Exports: Nearly 60% of the luxury SUVs built in Alabama get exported to global markets, delivering a positive contribution to the US trade balance.
Shutting down sales for a brand with that kind of domestic footprint would hit American worker paychecks as hard as it hits Stuttgart's bottom line.
Beyond Ownership Thresholds: Battery Software and CATL
The debate isn't just about who owns Mercedes shares. It's also about what goes inside the vehicles themselves.
Under amendments debated in the Senate Commerce Committee, the bill extends prohibitions to battery systems imported from Chinese battery makers like CATL. Modern electric car batteries aren't just chemical cells wrapped in aluminum—they run on complex Battery Management Systems (BMS) with microcontrollers and embedded firmware.
Critics of Chinese tech argue that an adversary with access to battery firmware could remotely manipulate charging cycles, override thermal management controls, or trigger battery fires. Senator Bernie Moreno made this explicit during committee discussions, arguing that unvetted electronics inside high-voltage batteries pose a physical security threat.
CATL insists that vehicle manufacturers retain absolute control over all data flows and software updates, leaving no path for remote interference. Still, if Congress bans Chinese battery electronics outright, almost every luxury automaker will face immediate production bottlenecks. Replacing CATL's battery management architecture isn't something an automaker can do over a weekend; it requires years of re-engineering and testing.
Why Lawmakers Are Reluctant to Back Down
You might wonder why Congress would risk harming a company that employs thousands of workers in Alabama and South Carolina. The answer lies in broader political pressure.
Lawmakers on both sides of the aisle are terrified that low-cost Chinese electric cars will flood the American market and crush Detroit's legacy automakers. We've already seen European markets struggle to handle an influx of subsidized Chinese EVs. Washington wants to make sure that scenario never happens on US soil.
When news broke that Mercedes was lobbying to raise the ownership limit, the House Select Committee on China posted a direct attack on social media, warning that a foreign company shouldn't dictate security policy to US lawmakers. Labor unions and domestic manufacturing groups have piled on as well.
This leaves senators in a tough spot. Voting to relax ownership caps for Mercedes makes a politician look soft on foreign security risks right before an election cycle.
What Happens Next for Luxury Car Buyers and Mercedes
If you're planning to buy a Mercedes anytime soon, you don't need to panic just yet.
The Senate bill includes a grace period for existing manufacturers. While new entrants would face an immediate block, companies already manufacturing and selling vehicles inside the US would have until 2030 to fully comply.
That gives Mercedes roughly three years to resolve its situation through one of three routes:
- Legislative Relief: Convince Congress to raise the ownership cap to 25% or pass a qualitative security assessment exemption before the bill becomes law.
- Shareholder Restructuring: Pressure BAIC or Geely to trim their holdings below the 15% combined mark, though buying back billions in equity is financially complex.
- Software Localization: Completely decouple US-market vehicle platforms from any international supply chains or components tied to foreign-adversary suppliers.
The Senate Commerce Committee cleared the bill for a potential floor vote, but the legislative path remains fluid. The Senate version must eventually reconcile with the House's Motor Vehicle Modernization Act before hitting the president's desk.
If you're an investor, auto dealer, or industry watcher, keep your eye on two key indicators over the coming months: whether the 25% threshold amendment survives the full Senate debate, and whether BAIC or Geely show any willingness to divest part of their holdings. How Washington handles Mercedes will set the blueprint for every international automaker doing business in America.
