Design work on the CRJ700 by Bombardier started in 1995 and the programme was officially launched in January 1997. The CRJ700 is a stretched 70-seat derivative of the CRJ200. Seating ranges from 66 to 78 for the CRJ700 versions, however. The CRJ700 features a new wing with leading edge slats and a stretched and slightly widened fuselage, with a lowered floor. The early build aircraft were equipped with two General Electric CF34-8C1 engines. However, later build aircraft are now equipped standard with the -8C5 model, which is essentially an uprated 8C1. Most airlines have replaced the older engines with the newer model, while a few have kept the older -8C1 in their fleet. The CRJ700 directly competes with the Embraer 170, which typically seats 70 passengers.
