The SDV capabilities on a model page predict whether a car will keep improving after purchase or stay as it shipped
ElectronsX model pages list software-defined vehicle capabilities because they predict how a car will age. A car with central compute, zonal wiring and OTA that reaches powertrain and driver assistance can gain range, charging speed and features after purchase; one that updates only infotainment will stay largely as it shipped. Each capability below is defined by what it lets the automaker do, not by marketing names.
OTA reach is the most telling single signal: many cars advertise "OTA updates" that cover only maps and apps. Full-vehicle OTA - including battery management and driver assistance - is still rare outside EV-native makers. See Why Full OTA Is Still Rare.
Capabilities
Capability definitions
| Capability | Definition | Why it matters |
|---|---|---|
| Central compute | One to three high-performance vehicle computers | Lets software reach many functions |
| Zonal E/E | Zonal controllers on an Ethernet backbone | Less wiring; path for updates |
| Full-vehicle OTA | Remote updates to powertrain, BMS, charging, ADAS, body | Fixes and features without dealer visits |
| Fleet telemetry | Continuous health and event data | Diagnostics, warranty, learning |
| In-house OS | Automaker-owned vehicle software | Speed of change |
| AI learning loop | Fleet data trains driving and energy models | Improves with use |
