Irizar i4H – A coach for tomorrow’s cities, today
The Irizar i4H is the first hybrid class II commuter/suburban coach for short- or medium-distance journeys or school transport, and is available in lengths from 10.7 m to 13 m on two axles. The 13-metre version has 53 seats with a double central passenger door, or 57 seats if a wide single central door is fitted instead. In either specification, the vehicle has a PRM (wheelchair) space and a luggage compartment that is large enough to provide adequate space on commuter lines.
The innovative Irizar i4H hybrid coach uses a parallel hybrid drivetrain, which combines a tried-and-tested Cummins ISBe 6.7 litre 300 hp diesel engine with an advanced Eaton PHP hybrid transmission, incorporating an electric inverter and traction motor-generator, together with a conventional six-speed automated manual gearbox.
The hybrid buses developed by Irizar reduce fuel consumption by 20%, which enables a saving of 6,000 litres of diesel per year. This also impacts on CO2 emissions, which are reduced by around 170,000 gr/year.
