Exhaust emission tests are reported on 2101 typical consumer-owned 1970 model production light-duty vehicles. The vehicles were procured and tested in six different metropolitan areas; Kansas City, Houston, Los Angeles, Detroit, Denver, and Washington, D.C. The total number of vehicles from each manufacturer (AMC, Chrysler, Ford, GM, and Volkswagen) was proportioned to represent the manufacturer's portion of the total production for 1970. For each manufacturer, combinations of engine size and transmission type were proportioned according to sales as closely as possible. Each vehicle was tested after accumulating at least 4000 miles, using the standard Federal 7-mode, 7-cycle Cold Start test procedure, and the Clayton KEY MODE test procedure. Average vehicle mileage was 10601.
