Mercedes-Benz has moved the start of next-generation GLC assembly at its Vance, Alabama plant from late 2027 to May 2030, a delay of roughly thirty months. The company confirmed the new date, telling Motor1: "Production has been rescheduled for May 2030".
Automotive News first reported the change, citing people familiar with the automaker's planning, and Mercedes has not publicly explained what drove it.
What changes at Vance
The original plan had the next-generation GLC rolling out of Alabama in the fourth quarter of 2027. That target is gone, replaced by a start date more than thirty months later.
The delay applies to the next-generation model, not to every GLC sold in the US. The current GLC already appears on plant lists for Vance alongside the GLE, GLS and the electric EQE and EQS SUVs, so at least part of US GLC output is already localised.
In spring 2026 Mercedes and state officials announced roughly $4 billion in new investment for the Vance operation tied to future SUV programmes, explicitly naming the GLC alongside updated GLE and GLS models. Once the expanded GLC line is running under that plan, the site's annual output is expected to top 280,000 vehicles a year.
Mercedes expects to build around 50,000 GLCs in the first 12 months of the new US line, though it has not tied that figure to a specific calendar year. Vance has built Mercedes SUVs since the 1990s, and the three-year slip changes the timeline for the expansion rather than the decision to build the GLC there.
The tariff arithmetic behind the wait
Mercedes has not named a single cause for the rescheduling, and the reporting available stops short of one. The practical effect is clearer: while the expanded Alabama capacity waits until 2030, a large share of GLC volume for the US still has to arrive from Europe.
Those imports carry the 15 percent combined tariff now applied to passenger vehicles from the European Union under the current US-EU trade framework. For a model built in the hundreds of thousands annually, that exposure compounds with every model year the delay stretches on.
That matters because the GLC is a volume model, not a niche import. Each year the Alabama line stays dark is another year of duty paid on cars that were meant to be built stateside, which is the kind of recurring cost that shows up in pricing and specification decisions long before it shows up in a press release.
A US footprint that keeps growing, slowly
Mercedes continues to build other US-market models domestically: the EQE and EQS SUVs at Vance, and the Sprinter van in South Carolina. The company has not announced a revised timeline for any other model as part of this change, and it has not said whether the 2030 start could move again.
For buyers, the near-term GLC on sale in the US is unaffected by the rescheduling: the delay concerns when the next-generation car will be built in Alabama, not whether the current one is available. The question the announcement leaves open is how Mercedes sources the next-generation GLC for US customers between late 2027 and May 2030, and the company has not detailed that.
