This significant update to our onboard computing system makes our vehicles more robust, less costly to produce and easier to service — all while improving the experience for our customers. Our new system also dramatically improves scalability for deployment in future vehicles. > Core to the new system is a substantial reduction in the number of electronic control units (ECUs) used to control the vehicle, down from 17 different ECUs in our first generation to just seven ECUs in our second generation. This massive simplification has been achieved by shifting to a zonal architecture and by significantly increasing the computational capabilities of each of our ECUs. While infotainment, autonomy, vehicle access, drive units and our battery management system each have their own ECU, every other vehicle function is controlled by just three ECUs. > Shifting to a zonal system enabled us to remove over 1.6 miles (2.6km) of wiring from each vehicle, shedding 44 lbs (20kg) of weight. This reduction in wiring, along with the elimination of 10 ECUs, greatly reduces production costs. Fewer components needing to be installed during assembly also improves manufacturing efficiency, allowing us to build vehicles more quickly and with better quality. With less components onboard, vehicles are easier to service and require us to stock fewer parts, improving serviceability.
