Tesla Cybercab Design Details — 2-Seat · 4680 · 48V · Steer-by-Wire
Published · Updated · By Investus editorial desk (SUNRYU Partners)
Tesla positions Cybercab as the primary vehicle in its Robotaxi fleet. It eliminates steering wheel, pedals and traditional controls to free up cabin space and reduce weight and operating costs. Core tech stack: 4680 battery cells, 48V architecture, and steer-by-wire.
Rationale for Seat Count
• 90% of ride-hailing trips carry 1–2 people → 2-seat is optimal
• Larger groups served by Model Y and other autonomous Teslas
Why Remove Traditional Controls
• No steering wheel, pedals, or dashboard cluster
• Reduced weight → lower operating costs
• Freed cabin space → improved passenger experience
Core Technology Stack
1) 4680 Battery Cells (in-house)
• Cost lead · supply security · higher energy density
2) 48V Architecture
• Thinner wiring, less mass
• More efficient power delivery to different parts of the vehicle
3) Steer-by-Wire
• Mechanical steering column removed
• Maximum packaging freedom
Robotaxi Fleet Composition Strategy
• Cybercab (2-seat) = core, low-cost workhorse
• Model Y and other autonomous Teslas = cover larger groups
Investment Implications
• Fewer parts → lower unit cost · improved per-trip EBITDA
• Capital efficiency at scale · Robotaxi economics maximized

Southeast Asia is opening; tariffs, price, and charging will decide how large the opening is.
