737NG Range confusion

[Captain Caveman 1]

Hi just something that poped up in my mind when looking at the specs for the 737NG;How come the -600 dont have the longest range whenits lighter, shorter and take less payload but has the samefual capacity ? i mean logics says to me that -600 should have the longestthen -700 ect.

Don't know about that 600/700 range difference but I have taken both across the pond on many occasions with 5k pounds of fuel left. The 600 should make it I don't see why it wouldnt. There is probobly a fuel load difference which accounts for the reduced range I haven't checked recently.Alex
