I appreciate the point about glass and weight but there's also the matter of functionality in relation to passenger amenity. You have to have windows that both the seated and standees can see out of. The other factor in relation to window-line (something I've learned from tram design) is that if the seat is too high in relation to the glazing, a passenger can be propelled through the glass in a side impact. There was a case in Singleton a while back where a schoolboy was killed going through the window in a school bus that was T boned by a truck.Daniel wrote:Let me put this simply. Less glass means less weight. Less glass means more efficient air conditioning. Both of these mean greater fuel economy. Standard side frames (yes they are produced as one piece and then sent to the factory for assembly) mean a more efficient and more standardised build process.
If you look at the photos I posted above, both Volgren and Custom keep their seat bases well below window-line (on the Volgrens the side windows at the back have an internal solid panel - only the outside glass goes down to the waistline). Bustech, in spite of the narrow windows, has its side-impact safety undermined by the continuously rising floor that forces the rear seats to be very high in relation to the window-line.
It was I who suggested here some time ago that somebody should visualise the CDi without a top deck and realise that therein lies the basis of a decent low-floor single-deck bus! Because, from that photo above, I'm not sure that the ZDi electric bus design is heading in the right direction. They need to reverse the priorities of aesthetic flair vs function.
In Europe, of all the manufacturers, Solaris likes most to play around with aesthetic touches but they remain subdued and strictly subordinate to pragmatism:
The SOR bus in my avatar ain't so bad either - aesthetic but also strictly pragmatic. Bustech on the other hand reminds me of those many car manufacturers who style a swish exterior and then, almost as an afterthought, jam an impractical interior into it. Design of a functional transport vehicle should absolutely start on the inside and work outwards.
