General Motors introduced the catalytic converter, a technology it had begun developing in the 1960s and the most important step forward in reducing automotive emissions to date. All 1975 model year GM cars sold in the U.S. and Canada were equipped with the catalytic converter, as are all cars sold by all competitors today.
Additional Information:
General Motors published a pamphlet about their newest innovation in 1975. It detailed how GM planned to use the catalytic converter to meet and exceed Federal emmissions standards in the future.
