What was the first car made that had computers, and by whom, and in what year?

Question

What was the first car (and by car I mean any vehicle - car, truck, etc.) manufactured that had electronic computer(s) in it. In other words, what car was the first to not be 100 percent mechanical?
Also, when I ask "what", I refer to the model of car, the year of car, the manufacturer of car, and the country of car manufacture or invention.
In addidion, I would really be pleased if somebody knows why cars became "electronic-ified", and what positives they were intented to bring forth.

Answer 1

Assuming we are talking about computerized engine and fuel management systems, the first one I know appeared on American Chrysler auto products with the 400cid engine in 1975. This advancement over electronic ignition systems was designed to coordinate the operation of both engine and fuel systems together to minimize emissions. Unfortunately the new technology and its reported unreliability were very disconcerting at first.
Electronic/computer ignition systems and fuel injection improved every possible engine function. Power, economy, engine life, reliability, component life, emissions and less maintenance all dramatically advanced. This trend will continue into the foreseeable future.

Answer 2

When electric lights were added to the Model T Ford, the beginnings of auto electrification began. Within a decade guages became battery powered and radios followed soon after. The last pure mechanical beast is probably over one hundred years old.

Answer 3

The 1975 Chevrolet Cosworth Vega was the first computer-controlled electronic fuel injected American car.

Answer 4

VW Beetle in 1939.

Answer 5

It was the 1899 Packard. Paul Harvey had this on one of his commentaries.
