Software development has becoming an integral part of automotive engineering. A premium-class automobile probably contains close to 100 million lines of software code executing on 70 to 100 ECUs throughout its body. Even the low-end cars have tens of million of lines of code on 30 to 50 embedded ECUs.

Following are how and where software is used in cars:
- Air-bag system
- Antilock brakes
- Automatic transmission
- Alarm system
- Climate control
- Collision-avoidance system
- Cruise control
- Communication system
- Dashboard instrumentation
- Electronic stability control
- Engine ignition
- Engine control
- Electronic-seat control
- Entertainment system
- Navigation system
- Power steering
- Tire-pressure monitoring
- Windshield-wiper control

As you can see from the list of features above, it is not wrong to estimate that more than 80% of car innovations come from computer systems and software has become the major contributor of car's value. The cost of software and electronics can reach up to 40% of the cost of a premium car today, and is expected to rise to 50% for conventional cars and 80% for hybrids within 10 years, according to experts.
