Exclusive: Cybercab runs more powerful FSD hardware than Model 3 and Model Y

Per sources cited by Not a Tesla App, production Cybercab units run a Full Self-Driving computer with more onboard RAM than today’s Model 3/Y HW4/AI4—currently capped at 32 GB effective (16 GB per chip × 2).

Why RAM matters

FSD neural networks grow with each generation. More RAM lets Tesla load larger models without memory bottlenecks. Tesla announced an AI4+ chip at Q1 2026 earnings with double package memory (~64 GB); the Cybercab may use an early variant or a dual AI4 board layout (Not a Tesla App).

Level 4 with no human backup

Cybercab first-responder documentation lists SAE Level 4 autonomous mode. With no wheel or pedals, compute hardware must support full autonomy. Tesla began testing control-less production units in Austin in late June (TechCrunch).

Fits the Impact Report narrative

The 2025 Impact Report ties the Cybercab to ~6.1 mi/kWh and nearly double per-mile emissions savings versus Model 3/Y—metrics Tesla also links to optimized software on dedicated hardware (Not a Tesla App, Sawyer Merritt).
