Customer TestimonialsVolvo 7900 Hybrid
Length: 12 m, rear mounted Volvo Hybrid
System.
Some say that hybrid technology is a solution for the
uture. True, but not the whole truth. Volvo hybrids
roam the streets o many cities the world over. Our
solution presents the best results over a wide range
of applications from extreme high-density city
centres to trafc in smaller cities and suburbs.
The Volvo hybrid system is unique in many ways;
technically and in terms o perormance and reliability.
Parallel hybrid
The solution means that the diesel engine and I-SAM
electricmotor work together under optimised conditions. The
power
management system decides which power source should
be engaged, and to what extent, at every given moment.
And, as opposed to many other solutions, should a ailure
disable the electrical propulsion system, the bus can still
run on the diesel engine alone.
Comments about our previous model,
the Volvo 7700 Hybrid.
Already rom the start we could see savings o 35 % in city
traic, and close to 25 % in intercity traic, compared to
our estimate o 20 %.
Dominik Steiner, owner of Steinerbus AG,
sub-contrac tor of PostAu to.
Most hybrid buses run in city traffic. But we wanted to find
a solution also or intercity operations. Volvos parallel
hybrid
seemed to be the right choice.
Werner Blatter, member of the management team of
PostAuto, Switzerlands leading bus operator.
Its an image matter or the the company but its not a
choice by chance, its by calculation. We wanted to make a
good investment and do something good or the planet.
Marc Sales, Owner, Sales-Lentz, Luxemburg.
I love this bus.
Tanja Reed, bus driver, Nettbuss, Trondheim Norway.
Operators tell us that the hybrid bus presents a higher
uptime
and is even more reliable than the corresponding diesel bus.
Edward Jobson, Prof. Environmental director, Volvo
Bus Corporation.

Torque
The diesel engine starts when the
electric motor has brought the bus up
to speed. The two power sources
then work in tandem, with the electric
motors impressive low-rev properties
adding to the diesel engines superior
pulling power at higher revs.
