Automobile manufacturers' suggested list prices on the 16 cars included in the producer and consumer price indexes are up an average of $365.85 on 1980 models, the Bureau of Labor Statistics said yesterday. [TEXT OMITTED FROM SOURCE] came from quality changes and about 30 percent from inflation, BLS calculated.

BLS said $255.20 of the total average increase was the result of these quality changes:

$118.04 for redesign of emission control systems to meet current and anticipated federal air quality standards. Modifications to catalytic converter systems accounted for $77.26 of this total.

$13.29 for changes made to meet current and anticipated safety standards, most of which related to bumper damageability standards.

$123.87 for other quality changes, such as engine and chassis changes for improved fuel economy and corrosion protection.

BLSbased its estimates on information for similarly equipped 1979 and 1980 model cars.

In accordance with past practice, changes made to resize passenger cars were not treated explicitly as quality changes, BLS said.

The impact of the quality changes on prices charged by the manufacturers when the cars are sold to dealers amounted $205.78. In other words, the new suggested list prices include a retail mark-up of $49.42 on the quality changes.
