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
