The First Integral Irizar i6S Efficient for Portugal


The Portuguese market already has more than 60 i6S Efficient units, Irizar’s most efficient bus. And that backs up the excellent results with up to a 13% reduction in consumption and emissions.

  • This new model has a weight reduction of up to 950 kg, a 30% improvement in aerodynamic coefficient, and a reduction in consumption and emissions of up to 13%.
  • It’s a latest generation vehicle that is designed to provide maximum efficiency for operators and the greatest safety for passengers.

The first integral Irizar i6S Efficient unit has been acquired by the Vale do Ave bus company and it will provide service in Rede Expressos. It is a 12.92 metre bus with 53 seats, a 450 CV DAF engine with 2300 NM of torque and it also has a large luggage compartment that is more than 12 cubic metres.

The vehicle has a digital camera system that provides an optimal panoramic view in all conditions and situations, either at night or in the rain, which also leads to a reduction in consumption. Those improvements mean a large part of the Irizar i6S Efficient buses produced for Portugal already have the digital camera system.

Furthermore, the interior of the vehicle has the best quality finishes with stainless steel handrails and LEDs on the stairs, among other things. And there is more room between the seats and more on-board connectivity.

A Safe and Connected Vehicle

The i6S Efficient is an efficient, connected and safe bus designed for the sustainable mobility of the future. It has a new multiplexed architecture and communications protocol that provides self-diagnosis services in real time. Irizar technology makes preventive maintenance and online monitoring for remote diagnostics possible. With our connectivity systems, 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 vehicle also has the most advanced active safety systems for preventing accidents, like the system for detecting traffic signals, pedestrians and bicycles, lane keep assist systems and collision warning systems, among others. Moreover, the vehicle has a reinforced structure that improves its response to torsion, flexing and head-on collisions, which improves passive safety.

Were not saying it, our clients are.

Excellent aerodynamic performance with improvements up to 30% and the weight reduction up to 950 kg are essential for this new generation of bus. The front of the vehicle and the roof have been modified and work has been done on the curve of the windscreen and the other front windows to lower air resistance to a minimum.

All of that has led to reductions in consumption of up to 13%, which is around 3 litres at 100 km. We’re not the ones saying it. Our Portuguese clients who already have an Irizar i6S Efficient in their fleets confirm it. The Portuguese market has already acquired more than 60 units and more than 20 units are already on the road. Companies like Rede Expressos and Flixbus, as well as some tourism clients, are the ones who have been most committed to this new model, and their response is clear: “We get extraordinary results with consumption below 20 litres”.

Like all Irizar models, the new Irizar i6S Efficient is available on any chassis on the market and in an integral version with two or three axles, from 10.78 to 15 metres and engines from 370 CV to 530 CV.
