BIG STORY/Irizar i4H integral Irizar UK has stolen a march on the rest of the industry by being the first dealership to bring a hybrid coach here in the form of a parallelconfigured, Cummins-engined i4H integral. The demonstrator has arrived already and the next step will be in-service trials to gain real-world experience of the applications that it suits best. A combined fleet of 30 i4H integrals and i3H integral buses on interurban work in Madrid have shown that a fuel saving of more than 20% over a comparable diesel is possible under some circumstances. “The hybrid needs varied driving conditions to deliver its best; if it is constantly used on the motorway there will be little benefit to fuel consumption,” says Irizar UK Business Development Director Julie Hartley. Instead, the i4H integral is tilted more towards work that involves some urban running. The demonstrator will enter service with Travel de Courcey on a corporate contract as part of the knowledge-gathering exercise, and Irizar UK already reports interest from other parties. “We will trial the coach with a variety of operators to get feedback on where it sits within the operational sphere,” adds Mrs Hartley. “But we believe that there is definitely a market for a hybrid. The more we see of it, the more excited we are to be the first to bring such a coach to the UK.” Weight the same In packaging the driveline, Irizar has maintained an unladen weight equal to that of a comparable diesel, and LEFT: The i4H integral packages a diesel-electric driveline into the existing i4 envelope with no impact on capacity HYBRID IS HERE FOR COACHES Alternative power has arrived in the coach sector with the Irizar i4H. It has a hybrid propulsion package and the dealership’s priority now is to gain inservice experience // We believe that there is definitely a market for this type of coach.
