Regional jet aircraft with 70–100 seats represent one of the most competitive segments in aviation. "Perviy Tekhnicheskiy" compared the Russian SJ-100 and the Brazilian Embraer E190-E2 across key parameters – from fuel consumption to operation.
Efficiency
The SJ-100 with PD-8 is estimated to be around 16–18 g/pass-km. The Embraer E190-E2 is at 13–15 g/pass-km.
The Brazilian airliner remains the benchmark for efficiency in its class due to new Pratt & Whitney PW1900G engines and optimized aerodynamics, thus confidently taking the first point.
Flight Range
The Embraer E190-E2 flies further and is capable of performing flights up to ~4500 km, confidently covering longer regional routes.
The SJ-100 is estimated up to 3000–3200 km, which makes it more oriented towards short and medium regional networks. Again, victory goes to the "Brazilian".
Capacity
The Embraer E190-E2 carries more passengers and comfortably accommodates up to 114 people, which enhances its per-seat economics.
The SJ-100 carries from 87 to 103 passengers, maintaining compactness, but is inferior in maximum load. So far, it's 0:3 in favor of Embraer.
Speed and Cruise
Both aircraft fly at almost the same pace: the SJ-100 accelerates to 870–900 km/h, while the Embraer maintains around 870 km/h.
The difference is minimal, and in real operation, they fly in the same speed range, which means it's a draw.
Operation and Infrastructure
The SJ-100 is just entering a new stage, gradually introducing the PD-8 engine and forming its own service ecosystem.
Currently, the advantage remains with Embraer due to its established operations and global service network.
Score 4:1 in favor of Embraer.
The Embraer E190-E2 confidently outperforms the SJ-100 in key parameters, however, the Russian airliner retains growth potential due to its new power plant and transition to a fully independent architecture.
