Zero emissionsIrizar Group Technology
Irizar, leader in innovation
Irizar, worldwide referential group of companies
in the passenger transport sector for more than
125 years, takes a new step along the route of
technological innovation and becomes a
referential company in the electrical bus sector.
A project fruit of the strategic commitment
for long term innovation of the Irizar Group
companies like Jema, manufacturer of high
range power electronics, Datik, technological
company developing intelligent solutions,
Hispacold, dedicated to acclimatisation systems,
Masats, dedicated to accessibility systems, and
Creatio, Irizar Group Research and Development
Centre.
The Irizar Group, formed by more than 3,500
people in their production plants in 6 countries
and with commercial presence in more than 90
countries of the 5 continents, is positioned as
leader in urban mobility and aimed towards the
future. A firm commitment for contributing to
sustainability and the environment, improving
the life quality of citizens thanks to innovation in
technology, electronics and telecommunications.
Something that is only possible thanks to the
commitment of all its persons, clients and
collaborators in the business project.

Sustainable urban mobility
Innovation in sustainability and the positioning
as technological leaders in the European market
has resulted in the first Irizar electrical vehicle for
future urban environments.
60% of the population in the European
Union live in cities and sustainable mobility is
one of the great challenges facing urban centres.
Circulation of vehicles is the cause of 40% of
CO2 emissions and 70% of other contaminants.
Acoustic contamination is worse; now more than
ever we need efficient, ecologic and silent means
of transport. Friendly and respectful with the
environment. That contributes to improving the
life quality of cities and of the people living in
them.
Electricity has been identified as one of the
most promising alternatives for transport and its
application in urban buses is gaining terrain. This
is the context where the commitment of the Irizar
Group is framed.

The Irizar i2e is the first urban bus developed
with our own technology. The project is the
result of the continuous work of the Irizar Group of
companies together with the Creatio
Research Centre and Development centre, from
which the latest advances in complete and
electrical buses have been born. Irizar,
manufacturer of buses, Hispacold producer of
acclimatisation equipment, Jema specialised
in high range power electronics,
Datik, technological company developing
intelligent solutions for transport, Masats,
dedicated to accessibility systems, and the
R&D centre Creatio, have joined forces to
impulse the Irizar i2e.
The new Irizar electric bus offers tested first line
technology developed in Europe, with cutting
edge design including pioneer technologies in
the sector. It also contemplates the incorporation
of another type of charging, like induction and
pantographic.
Irizar Group Technology
The bus of the future
The Irizar i2e is positioned in the market as the
bus of the future for cities, incorporating pioneer
technology which converts it into a reference for
sustainability and eco efficiency aimed at urban
mobility, responding to the current and future city
transport needs.
Full autonomy
The Irizar i2e has been designed to offer
autonomy between 200 and 250 km with only
one charge at the end of the day. Only five hours
of charge guarantees between 14 and 16 hours
of dense urban and interurban working conditions,
with an average speed of 17 km/h.
It includes market pioneering technologies, such
as pre-acclimatisation and Eco Assist in order to
optimise consumption. The pre-acclimatisation
allows the vehicle to leave the garage with an
optimal temperature using energy for the grid and
reducing energy consumption.
The Eco-Assist system assists the driver in real
time with the objective of reducing energy
consumption and that way increasing its
autonomy. It allows centralising the information
about consumption, the route, and the driver.
Sustainable and eco-efficient
Thanks to its zero emissions, as well as its silence,
the Irizar i2e is the ideal transport for cities and
their inhabitants. In addition to contributing to the
reduction of 88 tons of CO2 of yearly emission, it
allows saving 33,000 litres of fuel and provides
independence from the high prices of fossil fuels.
Its recyclability is another of its characteristics.
The Ecodesign principles have been taken into
account, applying environmental criteria in the
design of the bus. The batteries are 99%
recyclable and the bus is designed applying a high
percentage of recyclability parameters. This way
durability and profitability improve the operational
costs.

Safe, reliable and comfortable
The Irizar Group electrical bus has been designed
to comply with the highest demands regarding
active and passive safety. It is the first urban
electrical bus of the market that complies with the
R.66 anti-roll regulation.
The screwed aluminium structure of the bus is
another of its innovations. In addition to
thinking of its optimum modularity, it contributes
to an important weight reduction and
provides lower gravity centre. The rigid and
strong structure is conceived to reliably
support side and frontal crash situations, as well as
avoiding side roll.
The software has been designed following
the ISO 26262 recommendations regarding
functional safety. It also has anti-skid control and
with the memory system it is capable of efficiently
identifying and managing the energy flows and
peaks.
Like the other coach and buses in the Irizar range,
the Irizar i2e is conceived following the most
demanding parameters resulting in an especially
strong and reliable bus. It has been subject to hard
fatigue tests and reliability tests in one of the
most prestigious institutes of research applied
to automation on a worldwide level, the IDIADA
Automotive Technology, with excellent results.
The Irizar i2e is capable of maintaining the same
degree of thermal comfort as the other buses
in the Irizar range, because the heating and
acclimatisation equipment has not been forsaken
in order to achieve more autonomy.
In addition to introducing the most advanced
technologies in design, materials, components,
and production processes, the bus has maximum
quality finishes, making the Irizar i2e a completely
safe and reliable bus.

The bus of the future
Maximum profitability
The Irizar i2e offers maximum profitability
based on reducing electrical consumption, for
which it incorporates the most innovative energy
technologies. With a nominal power of 230 kW,
the onboard energy in the vehicle is 376 kWh,
thanks to which its autonomy is between 200
and 250 km depending on the driving cycle and
weather conditions.
In addition to the aerodynamic concept in the
design of the bus, weight distribution and
maximum accessibility to the components for
easy maintenance have been taken into account.
The management system of energy storage,
developed by Jema Energy, manages the relation
between battery and supercapacitators to
maintain the charge condition of the components
in an optimal range and, that way extending the
life cycles of the components, redounding in
improvement of the operational costs.
The Irizar i2e batteries have been working for
10 years as power supply systems and they
are 99% recyclable. This is a tested and reliable
technology. The battery charger is of the cable 2
type and allows charging in 5 hours.
In addition, the Irizar i2e has the coverage of the
Irizar guarantee.
