Tesla's Brandenburg plant is running about 1,000 cars a week behind the rate it needs, and the company has agreed mandatory weekend and night shifts with its works council to close the gap.
According to an internal message from the Giga Berlin Leadership Team to staff, obtained by Handelsblatt and reported on 4 September 2026, Grünheide is currently building fewer than 6,500 vehicles a week. The target is 7,500 a week from mid-October.
The shifts
The message tells employees: "Wir haben uns mit dem Betriebsrat auf folgende verpflichtende Sonderschichten im September 2026 geeinigt" — we have agreed with the works council on the following mandatory special shifts in September 2026.
| Date | Shift |
|---|---|
| Friday 18 September 2026 | Night |
| Saturday 19 September 2026 | Early |
| Friday 25 September 2026 | Night |
Grünheide runs three shift groups — Blue, Red and Silver — and each is affected once, so no crew works more than one of the three dates. The requirement covers the entire vehicle build including support functions. Battery and cell production are excluded.
The bottleneck is not the line speed
The detail that makes this more than a routine overtime notice is that Tesla has already hit its engineering target. The plant is running a 45-second cycle time — one car off the line every 45 seconds, down from 80 seconds, having passed through an intermediate goal of 60.
So the line moves at the speed it was designed to move at, and the output still is not there. That points at everything other than the takt: downtime, changeovers, supply, staffing on a given shift. Handelsblatt's assessment is that even with the three special shifts, the October target looks out of reach.
The plan behind that number is not new, which is what makes the shortfall notable. It was built in two steps. In April 2026 Tesla announced 1,000 new hires and a roughly 20% lift that would take weekly output to about 6,200. Then on 25 June, plant manager André Thierig set the 7,500-a-week target for October with another 1,000 jobs behind it. The hiring happened — a first tranche of 1,000 staff went in at the end of July. The workers arrived. The cars have not.
What 7,500 a week would actually mean
| Grünheide | Figure |
|---|---|
| 2025 production | ~202,000 cars (≈9,000 fewer than 2024) |
| 2025 capacity utilisation | 54% (from 56%) |
| 2025 revenue | €7.1bn (from ~€7.7bn) |
| 2025 net profit | €77.1m (from €56.8m) |
| Staff, end 2025 | ~11,000 incl. temporary workers |
| 7,500/week annualised | ~375,000 cars |
Those figures come from the plant's own accounts. The ambition is close to double what Grünheide built last year, from a site that has never run above 56% utilisation.
Why European buyers should care
Grünheide is where European Model Ys come from, so a plant short of its own plan is the plant setting your delivery date — and September, a quarter-closing month, is when that pipeline is tightest. That is part of why the shifts land where they do.
It sits oddly against the demand signal, too. Tesla more than doubled its German registrations in August to 3,034 cars in a record month for German BEVs, and was still outsold there by BYD.
The change of tone is marked. In June the ramp read as a vote of confidence in Grünheide. Three months on, the same target is being chased with compulsory weekend and night work.
For now the concrete facts are narrow and worth keeping separate from the speculation: three shifts are scheduled, the line runs at 45 seconds, and output is under 6,500. Tesla has not commented publicly on any of it.
