First of all, before the A vs B comes up, lets get this straight. I'm not an A or B fanboy. I'm just asking a few general questions about the two frames and why hasn't Airbus done more to make the A321 a more direct competitor with the 757-200. First of all, lets get the specs out there.
Length: 146 ft.
Height: 38 ft. 7 in.
MTOW: 196.2 (206.1) lbs. x 1000
Max Fuel Capacity: 6,260 gal (7,840 l)
Max Capacity: 185/220
Powerplants: two CFM56-5B or V2500
Max Range: 2,350 nm or 3,200 nm with sharklets
Length: 155 ft 3 in
Height: 44 ft 6 in
MTOW: 255,000 lb
Max Fuel Capacity: 11,489 gal (43,490 l)
Max Capacity: 200/228
40,200 lb (179 kN)
43,500 lb (193.5 kN)
Pratt & Whitney PW2037
36,600 lb (162.8 kN)
Pratt & Whitney PW2040
40,100 lb (178.4 kN)
Max Range: 3,900 nautical miles
So my question is, why hasn't airbus increased fuel capacity and added more efficient engines to make the 321 a better replacement/competitor with the 752? It seems like with larger wings (more fuel) a maybe a new engine option plus some AP winglets (which its getting) the A321 could be a more direct replacement for the 752. The more efficient engines and larger wings would increase range to allow it to do to TATL or Hawaii runs. Any thoughts? Now please no "the 757 is a great plane and A321 could never fill its shoes posts." Just speculation as to why Airbus hasn't made these modifications. Thanks!!
