Irizar i6S Efficient Launch; the most efficient coach in the history of Irizar

May 2022

Irizar is presenting a new generation of the Irizar i6S model coach that is more efficient, sustainable and profitable.

With the new Irizar i6S, consumption and emissions have been reduced up to 13%, weight is down to 950 kg and the aerodynamic coefficient is 30% lower. That makes it a latest generation vehicle designed to provide maximum efficiency to operators, the best experience to passengers and it emphasises sustainability.


Aerodynamic coefficient improved by 30%

Excellent aerodynamic performance is the key to this new generation of coaches. Part of the front of the vehicle and roof has been modified. The curvature of the windscreen and the other front windows have also been reworked to reduce air resistance as much as possible.

Furthermore, the Irizar i6S Efficient has the option to replace the rear view mirrors with digital vision cameras with the two-fold goal of providing wide-angle vision in any weather conditions. These modifications provide improvements in the driver’s direct and indirect field of vision.


Weight reduction up to 950 kg

Another major challenge was reducing weight. The weight of every component was analysed and reduced. And the weight of the vehicle has been redistributed with the goal of improving weight distribution.

High strength steel and lighter composite materials were used instead of traditional structural materials.

Thanks to those innovations we’ve been able to increase the space for passengers to improve ergonomics and comfort. We’ve also reduced noise and vibrations to the minimum. The cockpit has likewise been redesigned to be more comfortable and ergonomic and have a larger field of vision. The new line of Hispacold climate control devices is more compact, efficient and lighter.

That lets us make the travelling experience in this new Irizar as comfortable as possible.


A smart coach

The i6s efficient is a very efficient coach that is connected, safe and designed for the sustainable transport of the future.

It has a new multiplexed architecture and communications protocol can give self-diagnosis services in real time. Irizar technology makes preventive maintenance and online monitoring for remote diagnostics possible.

With the connectivity systems developed by Datik, all the data and usage statistics for the vehicle are stored in the cloud to maximise profitability, optimise route planning and minimise maintenance costs.

The i6S efficient has the most advanced active safety systems for preventing accidents. Moreover, the vehicle has a reinforced structure that improves its response to torsion, flexing and head-on collisions, also improving its passive safety.

We’ve increased and improved the driver’s field of vision. In addition, the digital camera system gives a panoramic view in all conditions and situations, even at night or in the rain.

Having the electronics in the central console, the accessibility of the controls and the virtual dashboard let drivers interact with the vehicle and quickly obtain all the information they need and administer the entertainment and comfort system.


Exhaustive studies and aerodynamic tests

Like all Irizar buses and coaches, the i6S efficient has been developed using the most advanced technology in design, materials, components and production processes. Fatigue and durability testing was done on it at one of the most prestigious research institutions in the world to ensure its reliability and quality.

Exhaustive aerodynamic studies and tests using simulators and measurements in real circuits have shown an exceptional 30% improvement in the aerodynamic coefficient and a reduction of up to 13% in consumption and emissions. Those demanding tests are proof of the solutions that make the i6S efficient a market leader in consumption and sustainability.


Maximum adaptation

As always at Irizar, we adapt to the specific demands of each market and client. And we offer the possibility to personalise vehicles with endless configurations for either right or left hand driving.

The i6S efficient is prepared for diesel, biodiesel, natural gas, biogas and it’s designed to be adapted to future zero-emissions models. The versions adapted to each market will be presented in every country during 2022.

Irizar is thus showing its firm commitment to its customers and society, to whom its products and services provide high added value whilst not ignoring fundamental elements like design, personalisation, safety, reliability and sustainability.
