I think we assume SAAB is developing a new 90 seater because they were in talks with GE regarding their new engine aimed at the 90 seat market. An artical recently suggests the CPX38 will be in the 4000-6000HP range. The original SAAB 2000 had a derated AE2100 set at 4150SHP. GE is looking for a 15-20% reduction in SFC on this engine with similar savings in maintenance costs due to electronic engine monitoring technologies.
Based on 15% fuel saving applied to the S20 it would have comparable fuel usage to the ATR42(500/600) per sector for a few more seats, 50 knots more speed and cruise altitudes up to FL310.
There is still some hope for a new 2000.
* I would expect the 15% reduction would be compared to current technology and offer much improvement over the AE2100 on the S2000.
