Bus Ikarus 280 is the only one which has 2 parts with 181kW x0.5 each.
Ikarus 293 has only one 200kW (x1.0) power part of 3.
Ikarus 260 with 141kW (x0.5)= 60kW is less powerfull than the old MB O 6600H with 107kW (x1.5)=164kW while having the same weight.

While it's true that it achieve 67km/h, there is no use of it intown where the speedlimit is 50km/h -> costing more getting (Price model, for theroretical reaching this speed) by the same Income (still 50km/h speedbonus) as before (MB 0 6000H).

so i would change it to x1 for power and a 50km/h variant to be a worthy of an townbus upgrade from the MB.

Wating for the 1980 bus then
