Autopilot Versions
SC01-eligible vehicles span several autopilot generations. Understanding which version your target vehicle has helps set expectations for autonomous driving capability.
Autopilot 1 (AP1 / HW1)
First-generation Autopilot developed in partnership with Mobileye. Cannot be upgraded to any newer hardware. Has reached its peak feature set.
Features
- ✓Autosteer (lane keeping)
- ✓Traffic-Aware Cruise Control
- ✓Auto Lane Change
- ✓Autopark
- ✓Summon (basic)
- ✓No upgrade path available
Hardware
- •1 forward-facing monochrome camera
- •Mobileye EyeQ3 processor (40nm, 500 MHz)
- •Bosch forward-facing radar (525 ft range)
- •12 ultrasonic sensors (~16 ft range)
Autopilot 2 (AP2 / HW2)
Tesla's first in-house Autopilot suite after ending the Mobileye partnership. Introduced 8 cameras for 360-degree vision. Computing unit can be upgraded to HW3.
Features
- ✓Enhanced Autosteer
- ✓Traffic-Aware Cruise Control
- ✓Auto Lane Change
- ✓Autopark
- ✓Summon
- ✓Navigate on Autopilot (via later software update)
- ✓Upgradeable to HW3 (computing unit swap)
Hardware
- •8 cameras providing 360° visibility (1.2 MP each)
- •Continental forward-facing radar
- •12 ultrasonic sensors
- •NVIDIA Drive PX 2 (GP106 GPU, 4 GB GDDR5, ~12 TFlops)
Autopilot 2.5 (AP2.5 / HW2.5)
Incremental upgrade adding a second system-on-a-chip to the NVIDIA Drive PX 2 platform for computing redundancy and improved safety. Computing unit can be upgraded to HW3.
Features
- ✓All AP2 features
- ✓Added computing redundancy for safety
- ✓Dashcam recording support
- ✓Sentry Mode support
- ✓Upgradeable to HW3 (computing unit swap)
Hardware
- •8 cameras (same as AP2, 1.2 MP each)
- •Continental forward-facing radar
- •12 ultrasonic sensors
- •NVIDIA Drive PX 2 + additional SoC for redundancy
HW3 / FSD Computer (Retrofit)
Tesla-designed custom silicon available as a retrofit for AP2/AP2.5 vehicles. Only the computing unit is swapped. Cameras, radar, and ultrasonic sensors from the original AP2/AP2.5 hardware remain unchanged.
Features
- ✓Full Self-Driving capability (with FSD purchase/subscription)
- ✓Traffic light and stop sign recognition
- ✓City street driving (FSD Beta)
- ✓Smart Summon
- ✓Only the computing board is replaced during retrofit
- ✓Free retrofit if FSD was purchased with the car, otherwise $1,000–$1,500
Hardware
- •Tesla-designed FSD Chip (14nm by Samsung, dual redundant processors)
- •144 TOPS compute, 2,300 frames/sec (21x faster than AP2.5)
- •Original AP2/AP2.5 cameras remain (8 cameras, 1.2 MP each)
- •Original Continental radar remains
- •Original 12 ultrasonic sensors remain
SC01 Vehicles & Autopilot
SC01-eligible vehicles shipped from the factory with AP1 (pre-Oct 2016 builds) or AP2/AP2.5 (Oct 2016 onward). However, the hardware you see today may not be what the car shipped with.
