Tesla Optimus V3: The Spec Sheet, Decoded — Production Date, Target Price, and 37 Joints

Tesla begins mass production of Optimus V3, its third-generation humanoid, in the summer of 2026. This is a plain-facts rundown of the two questions everyone asks — “what actually changed in generation three?” and “when does it ship, and for how much?” — using only what has been confirmed. Figures verified July 2026.

The quick sheet

Item	Optimus V3 (3rd generation)
Production start	Summer 2026 (July–August), Fremont
Height / weight	173 cm (5 ft 8 in) · 57 kg (126 lb)
Joints	37 — nine more than the 2nd generation
Walking speed	About 1.2 m/s (2.7 mph); keeps its balance on a 15-degree slope
Hands	22 degrees of freedom per hand, tactile fingertip sensors
AI chip	Tesla’s own AI5 (roughly 5x the bandwidth of gen 2)
Voice	xAI’s Grok
Target price	Under $20,000 at volume
Consumer sales	Targeted for late 2027

1. Production starts summer 2026, on a converted car line

Elon Musk reconfirmed the summer production start at the March 2026 Abundance Summit and again on the Q1 earnings call. After the last Model S and Model X cars roll off the line at Fremont, that line is being converted to build robots.

Musk himself has cautioned that with roughly 10,000 parts per robot, the early ramp is hard to predict — he expects actual output this year to stay in the thousands. Figures like one million units a year are mid-to-long-term goals, not 2026 plans.

2. The specs: 37 joints, an AI5 brain, a Grok voice

173 cm (5 ft 8 in) tall, 57 kg (126 lb)
37 joints — nine more than gen 2; walks at about 1.2 m/s and holds its balance on 15-degree slopes
Each hand has 22 degrees of freedom, with tactile fingertip sensors and force feedback
The brain is Tesla’s in-house AI5 chip, with roughly five times the bandwidth of the previous generation. AI5 taped out on April 15, 2026, and goes into Optimus and Tesla’s supercomputers before it goes into cars
Voice runs through xAI’s Grok

3. The price: under $20,000 is the target — the cost isn’t there yet

Musk’s stated target at volume production is under $20,000 per unit. The current estimated manufacturing cost, however, sits at $50,000–$100,000 — still a long way from the target. General consumer sales are targeted for late 2027. Both the price and the schedule can move; treat every number here as a company target, not a promise, and make purchase or investment decisions on your own judgment.

4. The competition: Figure is inside a BMW plant, China is cutting prices

Figure AI has put its newest robot, Figure 03, to work in logistics (parts sequencing) at BMW’s Spartanburg plant in the United States. Its predecessor, Figure 02, helped build more than 30,000 BMW X3s over roughly ten months. In Europe, BMW’s Leipzig plant became the first to take on Hexagon’s AEON humanoid. Meanwhile, China’s Unitree and others are pulling average humanoid prices down fast with low-cost models and joining the volume race. Mentions of companies here are not recommendations to buy any stock; investment decisions are your own responsibility.

FAQ

Q1. Can I buy an Optimus V3 now?
No. Right now it works only inside Tesla’s own factories. General sales are targeted for late 2027.

Q2. How much will it cost?
The target is under $20,000 at volume, but today’s estimated build cost is $50,000–$100,000, so early prices could land higher.

Q3. What is the biggest change from generation 2?
Three things: nine more joints (37 in total), Tesla’s own AI5 chip plus a Grok voice, and a new body engineered for mass production rather than lab demos.

The takeaway

Optimus V3 is the inflection point where Optimus stops being an R&D robot and starts being a manufactured product. Watch three axes — the joint count, the AI chip, and the target price — and the shape of the change stays easy to track.
