Update: Now that deliveries of the refreshed Model S have started arriving to customers, we can confirm that the rumored triple-camera autopilot system in fact has not been installed in the vehicle. Still one camera, but no less awesome.
Rumor has it there's a new Autopilot camera system lurking behind the windshield of the refreshed Tesla Model S. According to CleanTechnica, the 2016 refresh brought more than a revised front fascia and interior — it also brought a new triple-camera module for the Autopilot system.
The current single lens camera and other components are produced by Mobileye, and they just so happen to offer a trip-camera setup as well. The three-camera system enhances an autonomous driving system's field of view, adding to the standard field of view a camera with a narrow lens for better resolving straight-ahead vehicles and another camera with a fisheye lens for picking up cars on the periphery.
This doesn't, however, constitute a fully-autonomy camera system unless Tesla has somehow managed to sneak these cameras into the sides and rear of the car. The current suite of 12 ultrasonic sensors around the Model S have a range of 16 feet — good for slow maneuvering like Summon and lane changing, but not for managing driving around a city.
Supposedly also included but not yet activated is a pedestrian noise speaker, meant to alert unsuspecting pedestrians and bicyclists to the presence of your ultra-quiet Tesla. The speaker would provide compliance with an expected NHTSA regulation requiring EVs to generate audio alerts when traveling slower than 18mph. The NTHSA estimates that the quiet nature of EVs ups the odds of a pedestrian collision by 19%.
Now, this is an unsubstantiated report which other outlets are disputing, so we'll take it with a grain of salt. Tesla has declined to comment, calling the report speculation.
That said... Tesla has been known to make silent hardware upgrades and flip the switch months down the road when the software is ready. That's exactly what Tesla did with the first version of Autopilot — they announced Autopilot for the Model S in October 2014, but had started manufacturing the car with the hardware weeks prior.
