The Paris differed from the majority of liaison aircraft then in service by its use of jet propulsion, instead of a turboprop or piston engine. According to M. Vichou, the head of the design department of Morane-Saulnier, the decision to adopt a pair of Turbomeca Marboré jet engines had been determined to be the superior option available; studies found that a single turboprop engine capable of providing at least 2,000 hp was necessary to produce a comparable performance, which would have resulted in the additional complications of appropriately accommodating a fairly large propeller in the design. Another alternative in using a pair of small turboprop engines was also less convenient than the Marbore engine, which could be positioned relatively low down in the airframe and in close proximity to the aircraft's centre-line.
