Aviation: Study Shows that E190-E2 is 17% more fuel efficient than the E190 among other differences

The Embraer E190-E2 forms part of a range of aircraft following on from the original popular E-Jet series.

A report from simpleflying.com reveals that it has been three years since the E190-E2 was first certified. But, how does the jet compare to its predecessor, the initial E190?

The Major Upgrade

Notably, the E190-E2 is primarily a re-engined model of its predecessor. The Pratt & Whitney PurePower Geared Turbofan engines replaced the General Electric units. This aspect was part of a key area of advancement with E2, which is in regard to efficiency.

Following final flight tests of the E190-E2, at the beginning of 2018, Embraer highlighted that the aircraft proved to have 1.3% better fuel consumption than expected. Moreover, the progress is a 17.3% improvement when up against the E190.

Furthermore, the new engine’s fan diameter is over 20 inches (50 cm) wider. Subsequently, the nose wheel undercarriage had to be extended.

The manufacturer also highlighted that the E190-E2 would become the most environmentally friendly plane in its segment, touting the lowest level of external noise and emissions. The company added that the cumulative margin to ICAO Stage IV noise limit “increases from 17 to 20 EPNdB, which results in 2 EPNdB better than its direct competitor.”

Additional Advantages

Embraer also emphasized general improvements across the board. From range to maintenance costs, there are benefits to be had with the upgrade.

“Flight test results also confirmed the E190-E2 to be better than its original specification in takeoff performance. The aircraft’s range from airports with hot-and-high conditions, such as Denver and Mexico City, increases by 600 nm compared to current generation aircraft. Its range from airports with short runways, such as London City also increases by more than 1,000 nm allowing the aircraft to reach destinations like Moscow and the north of Africa,” Embraer shared in a statement.

“E190-E2 also becomes the aircraft with the longest maintenance intervals in the single aisle market with 10,000 flight hours for basic checks and no calendar limit in typical E-Jets utilization. This means additional 15 days of aircraft utilization in a period of ten years compared to current generation E-Jets.”

Across the Spectrum

On its website, Embraer lists the range of the E190 at full capacity to be 2,450 NM / 4,537 km. Meanwhile, this figure for the E2 is 2,850 NM / 5,278 km.

Another slight difference is in the seating. The typical capacity on the E190 in a single class at 32″ | 31″ pitch is 100 seats. Meanwhile, this number rises to 106 on the E2 at 31” pitch. Nonetheless, both aircraft can fit 114 seats at 29″ pitch.
