Hybrids are another kettle of fish and they are really, only designed for town and city use. Looking at the Euro 6 range, the Volvo B5TL, Cummins ISBe and the new Merc 5.1l will be able to handle city / urban routes like the 21. What I'm talking about is endurance and rural routes such as GNE's TTX and 10 and also ANE's X15, X18, X21 and X22. Them routes won't allow buses that were built for city / urban use to be used on them due to the demands required.
