What is the maximum motor power of Chevrolet Astro?

The Chevrolet Astro van never had a single, consistent engine throughout its production run (1985-2005). Therefore, there's no single "maximum motor power." The power output varied depending on the year and engine option.

The highest horsepower engine option available for the Astro was typically a 4.3L V6. However, the exact horsepower rating fluctuated over the years, ranging from approximately 190 to 200 hp depending on the model year and specific configuration.
