Notes
  1. ^ All cars sold after October 2016 are equipped with Hardware 2.0, which includes eight cameras (covering a complete 360° around the car), one forward-facing radar, and twelve sonars (also covering a complete 360°). Buyers may choose an extra-cost option to purchase either the ”Enhanced Autopilot” or ”Full Self-Driving” to enable features. Front and side collision mitigation features are standard on all cars.[28]
  2. ^ Also known as ”Hardware 2.1”; includes added computing and wiring redundancy for improved reliability.[25]

Hardware 1[edit]

Vehicles manufactured after late September 2014 are equipped with a camera mounted at the top of the windshield, forward looking radar (supplied by Bosch)[47][48] in the lower grille and ultrasonic acoustic location sensors in the front and rear bumpers that provide a 360-degree view around the car. The computer is the Mobileye EyeQ3.[49] This equipment allows Model S to detect road signs, lane markings, obstacles, and other vehicles. Upgrading from Hardware 1 to Hardware 2 is not offered as it would require substantial work and cost.[50]

Hardware 2[edit]

Hardware 2, included in all vehicles manufactured after October 2016, includes an Nvidia Drive PX 2[51] GPU for CUDA based GPGPU computation.[52][53] Tesla claimed that Hardware 2 provided the necessary equipment to allow full self-driving capability at SAE Level 5. The hardware includes eight surround cameras and 12 ultrasonic sensors, in addition to forward-facing radar with enhanced processing capabilities.[22] The Autopilot computer is replaceable to allow for future upgrades.[54] The radar is claimed to be able to observe beneath and ahead of the vehicle in front of the Tesla; the radar can see vehicles through heavy rain, fog or dust.[55] Tesla claimed that the hardware was capable of processing 200 frames per second.[56]

When ”Enhanced Autopilot” was enabled in February 2017 by the v8.0(17.5.36) software update, testing showed the system was limited to using one of the eight onboard cameras, the main forward-facing camera[57] The v8.1 software update released a month later enabled a second camera, the narrow-angle forward-facing camera.[58]

Hardware 2.5[edit]

HW 2.5 (also known as ‘2.1’) included a secondary node (without a GPU) to provide more computing power and wiring redundancy to slightly improve reliability.[25][59]

Hardware 3[edit]

According to Tesla’s Andrej Karpathy, as of Q3 2018, there have been large neural networks developed for Autopilot that cannot be used due to the lack of computational resources in current Tesla hardware. The next version of the hardware (3.0) will provide the resources to allow for improved accuracy in predictions.[60]

HW 3.0 includes a custom Tesla-designed processor using application-specific integrated circuits (ASIC) chips. Tesla claimed that the new system would process 2,000 frames per second, 10 times more powerful than hardware 2.5.[61][62] The firm described it as a ”neural network accelerator”.[56] The company claimed that 3.0 was necessary for ”full self-driving”, but not for ”enhanced Autopilot” functions.[63]

In October 2018, Tesla estimated first availability of Hardware 3 to be April 2019[64], however Tesla started delivering some Model X vehicles with Hardware 3 around March 22, 2019[citation needed].

Elon Musk stated that customers who purchased the Full Self-Driving package will be eligible for upgrade to HW 3.0 without cost.[65]
