Tesla opened its European engineering centre in Berlin-Köpenick on Wednesday, 4 November 2026. The Berlin Tesla Engineering Center (BTEC) starts in partial operation with about 250 engineers and technicians, according to Tesla, and is meant to grow to around 500 once a second section of the building is converted. Tesla puts the total investment at about €100 million (rbb24; heise online).
What the centre does
Tesla says the site combines materials, powertrain and vehicle development with validation and safety testing in 30 specialised laboratories, "covering the entire value chain". A large test hall is used for safety tests on vehicle components, including airbags, and for tests on battery cells.
The staff are not new hires. Tesla says they previously worked at other sites, including its facility in Tilburg in the Netherlands and other laboratory locations. According to the company, the Berlin team's earlier work fed into the Model Y, the Semi and the Roadster, and what it develops will also be applied at the Grünheide factory, Tesla's only car plant in Europe.
Tesla converted a disused factory building in Köpenick for the centre. It said the permit for the second expansion stage has already been applied for.
Bigger than the 2025 plan
When Tesla vice president and engineering chief Lars Moravy announced the project in September 2025, the numbers were smaller (rbb24, 2025). TeslAnt reported the plan at the time in our September 2025 report on Tesla's Köpenick centre.
| Announced September 2025 | Opened November 2026 | |
|---|---|---|
| Staff at the start | 130 engineers, moving from Grünheide and smaller Berlin sites | About 250 engineers and technicians, from Tilburg and other lab sites |
| Longer-term headcount | Up to 250 | About 500 after a second stage |
| Investment | An "upper double-digit million" sum in euros | About €100 million |
| Focus | Materials research, vehicle and powertrain development; new EVs, batteries and charging infrastructure | Materials, powertrain and vehicle development, plus validation and safety testing in 30 labs |
The headcount Tesla described in 2025 as the eventual size is now the starting point, and the investment has moved from an unspecified double-digit sum to a round €100 million.
Berlin's Governing Mayor Kai Wegner called the opening "a strong signal for our city and a clear commitment to Berlin as a business location". Tesla said the centre "once again underlines Tesla's long-term commitment to Germany as a strategic innovation location".
What it means for European owners
Nothing changes for a car on sale today. What changes is where the work is done: component validation, airbag safety tests and battery-cell tests now sit in Berlin, next to the factory that builds the Model Y for European buyers, instead of being spread across several sites.
The opening also fits the direction Grünheide is taking. In October Tesla told Brandenburg's public broadcaster that it intends to apply for a partial permit for a second production hall there, the next step in the expansion from 500,000 to one million cars a year, as covered in our report on the Giga Berlin second-hall filing.
Tesla has not said which current projects the Berlin engineers are working on, or whether any vehicle will be developed specifically for Europe there.
