The same chassis, but with larger engines, placed higher on the wing giving rise to different handling characteristics, especially at the edges of the performance envelope. The instrument layout is different and center panel control locations differ. Both of these changes lead to different instrument scan procedures and in the event of a high-stress condition --when seconds count, as instincts and muscle-memory kick in-- it feels like a different aircraft.
