I agree.
There nothing different to the 15m Omnilinks though, Same mechanically ( obviously running on diesel instead of CNG and have more uprated power setting than the E300s )
I tend to find CNG fueled buses to have a bit more extra speed In them compared to Diesels, Have regularly achieved upwards of 65-70mph on Arriva's MAN Ceatanos on the X21, They also tend not to be speed limited for some reason, Reading Buses achieved 76mph on Millbrook test track using one of their Scania CNG E300s.
