Even though the drag co-efficient may be lower than a upright (or 'safety cycle') due to a lower stance or fairings, recumbents are generally wider, have additional guides or jockey wheels on the drivetrain, & usually run an additional wheel (trike) which is bound to offset any sort of drag efficiency from it’s lower vertical stance compared to a two wheeled bike.
Perhaps I’m thinking too generally & recumbants do come into their own in certain situations?

'Bents are not all-conquering however: they suck on uphills.
Although the geometry is different, the concept is similar to this racer of mine:

Fixed linky for you.
That is a TriSled RotoVelo. A commuter-targetted recumbent with a tough roto-moulded plastic fairing.
