Model test with closed-loop catalytic converter

At the Sindelfingen plant, Dr Rudolf Eberle, Baden-Württemberg's Minister of Economic Affairs, takes delivery of three Mercedes-Benz 230 E passenger cars fitted with closed-loop catalytic converters and designed to run on premium petrol. The cars will be used in a pioneering model test conducted by the state government, in which two identical vehicles without catalytic converter also participate for the purpose of comparison.
