The 48-seat jet would be stretched over the Challenger by a 128 in (3.3 m) forward plug and a 112 in (2.8 m) aft plug. Over 300 mi (480 km) routes, the faster climb and cruise gave it a one third time advantage to 50 min compared to similarly sized turboprops. The higher cost per seat of the RJ, of $270,000 each compared to $186,600, would be balanced by its higher productivity.[8]
