BYD and Yutong have a bit of technical issues after numerous testing during hot weather..Hmm haven’t start operations already got problem eh..
On a side note,Future bus procurement is only Hybrid or electric and say bye2 to full diesel buses.
Hope will be MB Citaro Hybrid,Volvo B5LH(With different bodywork) & MAN lion City hybrid.For DDs,Can opt for Enviro500 Hybrid,A95 Hybrid(If they have) and Volvo B8L Hybrid.
Also can try A24 Hybrid for Airport and short distance feeders.Buy Hybrid opposed to fully electric
