Tesla is unique because they are both a hardware company and a software company. The main brain of the Tesla car is it’s MCU or media control unit. Up until 2018, the MCU of the Teslas was an NVidea Tegra 3 chipset. In that year Tesla moved to an Intel Chipset and when it did that the new Tesla Model 3 software got a lot faster.
Unfortunately for people who had the older computer the software started to fall behind. Unlike an iPhone that perhaps is easy to upgrade every 2-5 years, it’s much more expensive and complex to upgrade a car. Luckily Tesla recently released a hardware upgrade that essentially replaces the main computer of the Tesla.
Take a look as we upgrade the main brain of a Model S with a new MCU and the Full-Self-Driving computer, the FSD.
