اذا كانت المحركات بنفس كفاءة تلك المركبة على اليوشين فهي ستكون ممتازة

أخي المحرك الذي أستخدم في تجربة الطائرة هو  Pratt & Whitney PW1000G و هو من إنتاج أميركي و لكن المحرك المخطط لإستخدامه بشكل أساسي على الطائرة (بجانب  الأميركي Pratt & Whitney PW1000G) هو المحرك الروسي Aviadvigatel PD-14 (و هو أفضل من محرك الأليوشن Aviadvigatel PS-90)

To resist the Airbus-Boeing duopoly pressure on regional jets through the Embraer E-Jet E2 and the Airbus A220, Sukhoi upgrades the SSJ100 as the SSJ100B and the "Russianised" SSJ100R. The SSJ100B would feature more powerful SaM146-1S18 engines, improved avionics software, enhanced high-lift devices controls and retrofit-able "sabrelets" blended wingtip devices. Its navigation system would be tested in the North Pole. The SSJ100R western components are replaced by Russian ones for governments and Western-sanctioned countries.[64]

Western content accounts for 55-60% of an SSJ100 cost but sanctions against Russia are tightening. Replacing US parts like INS, APU, and cabin by Russian or European substitutes will allow deliveries to Iran Air Tours and Iran Aseman which signed letters of intent for 40 in 2017, but European partners will not risk US retaliation. After 2021 the SSJ100R will be produced without Western components: the Thales avionics would be replaced by KRET ones and the SaM.146 engines by a PD-9 scaled down Aviadvigatel PD-14, reducing fuel burn by 5-8% with a new composite wing.
