for a better world
better business
Environmental perormance is no longer considered a
sot issue. For public transport operators it is a means
o competition. Governments, cities and authorities are
becoming increasingly clear in their requirements or
sustainable city trafc, and those operators who can
respond to this defnitely gain the upper hand in their
business process.
At Volvo we took on this challenge many years ago.
We are able to act and improve in many areas. Hybrid
technology constitutes a major step towards reducing
the use o ossil uels, and we can present a solid
track record rom years o commercial operation.
Volvo strives or thorough long-term sustainability.
We are convinced that buses are the best way
to oer efcient public transport. That’s why we
constantly seek ways and means o enhancement.

The new Volvo 7900 Hybrid
The Volvo 7900 Hybrid is our second series-
produced hybrid bus model. Its predecessor
has been on the market or some years and both
uel savings and reliability have been proven in
commercial operation. Our hybrid technology is
probably the most versatile driveline solution there
is when it comes to combining environmental im-
provement with perormance, economy and uptime.
When you save as much as 39% in uel con-
sumption, you also reduce CO2
emissions by the
Silent boarding and take-off
Your passengers will beneit rom
hybrid technology as well. The Volvo
7900 Hybrid can take o silently with
the diesel engine shut o. This, and the
absence o engine idling, substantially
reduces noise. And at the bus stopthere are zero tailpipe emissions.
Add to that the electric doors which
close more smoothly – and contribute
to the uel saving.
Intelligent energy recovery
Volvo has a unique principle or recovery
o braking energy, using the intelligent
unctions o the Volvo I-SAM. Through
close monitoring and a specially de-
veloped algorithm these currents can
be controlled and optimised to extendbattery lie.
Electrical auxiliaries
Many systems in a bus require
continuous power supply. Normally
this comes rom the engine via
mechanical drive. In the Volvo 7900
Hybrid these systems are electrically
powered, which means that the busis ully operational even when the
diesel engine is switched o.
same amount. And when it comes to nitrogen
oxides and particles the reduction is even greater;
up to 50% compared to the average Euro 5 diesel
bus. The reason why Volvo can present better
fgures than others is no secret. The solution itsel,
the parallel hybrid, is highly efcient, the I-Shit
gearbox provides optimised conditions, and we
keep the batteries in the best possible condition
by providing both cooling and heating.
Save up to 39% uel and
reduce emissions even more.

on and on
It just goes on and
A Volvo is reliable
Our quality reputation is solid and our new body concept
is another step towards perection. The principle o best-
choice materials means that we use both steel and alu-
minium in the structure. Aluminium is corrosion-resistant,
which is an important actor or the expected service lie
o the bus. And up to 90% o the aluminium structure can
be recycled.
World-class driver’s compartment
The driver’s environment is one o the best available.
Clear and logical layout o instruments and controls,
superb visibility and a seat with very generous adjustment
range all contribute to the world-class ergonomics. It’s easy
to ind the ideal driving posi tion, regardless o the driver’s
height, build or personal preerences.
Quick and smooth
The high passenger capacity is accompanied by wide,
electric or pneumatic, doors and an interior truly built or
the passengers. Easy entry and exit mean a lot or passen-ger low and overall productivity. And the new electric doors
require considerably less adjustment and maintenance.
New body concept
The new body concept is shared with the rest o the Volvo
7900 range – and with the Volvo 8900. This means that
your entire leet can beneit rom 70% parts commonality.
Add to that the extended warranties and simpliied repairmethods; much o the minor damage that requently occurs
in city traic can be repaired without welding.

Customer Testimonials
Some say that hybrid technology is a solution or
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 o applications.
From high-density city centres to trafc in smaller
cities and suburbs – in all types o climate.
The Volvo hybrid system is unique; 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 est imate o 20 %.”
Dominik Steiner, owner of Steinerbus AG,
sub-contractor of PostAuto.
“Most hybrid buses run in city traic. But we wanted to ind
a solution also or intercity operations. Volvo’s parallel hybrid
seemed to be the right choice.”Werner Blatter, member of the management team of
PostAuto, Switzerland’s leading bus operator.
“It’s an image matter or the the company but it’s not a
choice by chance, it’s 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 uptimeand 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
motor’s impressive low-rev properties
adding to the diesel engine’s superior
pulling power at higher revs.
