The only choice might be the Citaro, due to 265hp(but still
slightly underpowered for an SD, which requires at least 280hp.)
DDs need 310hp while bendies need 320hp.
I think all the SBST WAB SDs are below 280hp, KUBs, Citaros,
B7RLE, the de-registered MAN demo(Not sure), and the Sunlongs. The
only way is to choose the one that has the highest torque output as
Mt Sinai Estate can be hilly and has lots of sharp turns comparable
to Sth Buona Vista Rd. Also, the model must also be in large
quantity, as 92 has about 10 buses.
Currently, the only choice that they have is the Citaro, but...
underpowered... Still able to handle the slope though, as the B10Ms
have about 250hp.
Citaro 286PS (ard 282hp), KUB 230hp, B7RLE 290hp, MAN 18.240
240hp, Sunlong 230hp, B10M 245hp. Citaro should be able to handle
though.
