The engine out scenario makes sense - the traditional design of all engines rotating inwards to the fuselage would increase Vmc (and decrease climb performance) compared to this design.
Another consequence has been the possibility to improve by four per cent the lift at low speed
That's what I'm wondering about. Could this possibly have to do with the slipstreams joining together in more 'harmony' (compared to all props rotating toward the fuselage) resulting in a reduction of lift-induced drag which, according to the marketing department, is the same as an increase in lift? It makes sense that they specify low speed as this is where the direction of rotation really matters - in this regard.
