How many ECUs are there in a car?
The number of Electronic Control Units (ECUs) in a car can vary between 20-100+ depending on the vehicle class, level of electrification, and feature set. Low specification vehicles typically have around 20-30 ECUs for basic powertrain, chassis, and body-electronic control. Mid-range models more often integrate 30-70 ECUs to support increased connectivity, comfort, and safety systems.
