Variants

The original design had a windscreen (and matching rear windows) of the same height as the side windows. It remained in production (with a new design of grille) alongside the Dominant II, whereafter it was known as the Dominant I.

The Dominant II (introduced in 1976) had a deeper windscreen, rectangular headlights and a flat rear window.

The Dominant III had shallow, parallelogram-shaped side windows. The Dominant IV had conventional-shaped side windows, but shallower than those on the Dominant II.

The Duple Goldliner was a high-floor version of the Dominant III or IV.

The Duple Dominant E was a bus-specification version of the Dominant I or II. It is not to be confused with the visually dissimilar Dominant Bus which was available from 1974 to 1987.
