It was decided that the five-door hatchback version would be engineered first. It was given its own project designation, LM10, with this version to be launched as the Austin Maestro. The name "Maestro" had been a finalist when the Austin Metro was being named, with the third choice ("Match") never picked up. The booted notchback version was to follow and it was designated as LM11, although its development was to diverge from the original path, it was later launched as the Austin Montego on its launch in April 1984, following British Leyland's decision to discontinue the Morris marque.
