Volvo’s new hybrid version of the 7700 bus was unveiled in Germany at the IAA Bus and Truck Show. While it’s not as exciting as, say, the new Volvo S40, it’s something. It’s eco-exciting… eco-citing. Lame?
Well, whatever, I think it’s interesting.  This new version of  Volvo’s 7700 bus will be 30% more fuel-efficient than non-hybrid models.   It has a smaller 5.0L diesel engine compared to a regular 9.0L diesel  Volvo 7700, but it’s built on the same platform.  It’ll save on fuel  costs, be able to fit more passengers, and have less emissions and  vehicle noise compared to normal diesel buses.
