Question

What year was the first airbag installed in a mass produced car?

Answer 1

1980 (Mercedes Benz S-Class).

Answer 2

I believe the answer above is correct.  However, there were joint projects in the 70's with the domestic manufacturers and insurance companies.  Several thousand of these cars were on the roads and they were studied when they had an airbag deployment.  Hope this helps!
