Which design patterns are used in this example?

The following example is an older exam question I am trying to understand. The question is: Which design patterns are used in this ClassChart?

In my opinion there is the composite pattern:

• "Car" class as component
• e.g. "Sportscar" class as composite/leaf

and the decorator pattern:

• e.g. "Sportscar" class delegates via "base.speed()"

However, this ClassChart looks very strange to me and it's hard to actually understand, whether I am right with those two patterns and, whether there are more patterns I don't see.
