A 1981 AMC Spirit powered by a 53-kW Stirling engine was evaluated for performance, emissions, fuel economy and cooling-system adequacy. Originally assembled as a transient test bed for the engine, the 3250-lb vehicle lacked sufficient power for contemporary acceleration performance. Using a chassis dynamometer, the engine was evaluated as if it were installed instead in a 2500-lb Chevette in order to approximate the performance of that production car. Current emissions standards were met at low mileage by the Stirling engine without a catalytic converter. The simulated Stirling Chevette matched the fuel economy of the production Chevette on the highway, but fell significantly short on the urban schedule. Most of this shortfall was traced to the required warmup time and high idle fuel rate of the Stirling engine. The cooling system performed satisfactorily in wind-tunnel tests conducted at elevated ambient temperatures.
