Everything's a trade-off. The engines on these buses were developed in 1994 when the available technology was limited and the goal was to approximate the performance of the corresponding Euro I diesel engine with reasonable reliability The successor engine, developed in 2000, does feature turbocharging..
@@jetstream454 O405s whether turbo or non turbo both perform the same, the turbo was only introduced for engine efficiency, they all hate hills but its the cng ones that absolutely hates it lol
Great ZF and kickdown!
if only it had a turbo
