Irizar i4: city and intercity bus, engines and versions
Irizar i4 — the city and intercity bus chassis from the Spanish manufacturer, introduced in 2011. We look at its purpose, chassis options and what to check when buying a used one.
Irizar i4 in brief
The Irizar i4 is designed for city, intercity and school runs. Unlike the tourist-focused i6, it features a more functional interior with more standing room, wider doors and easier boarding.
The chassis is built by Irizar, while the drivetrain and transmission are usually from Scania, Volvo or MAN. Therefore, each example can have different mechanics.
Versions and purpose
The i4 is produced in various lengths and seating configurations: from shorter city buses to longer intercity models. They differ in floor height, number of doors and luggage compartment capacity.
Later, hybrid and other alternative transmission versions appeared, but in the Lithuanian used market, conventional diesel examples are most common.
Engines and gearboxes
Engines depend on the chassis: Scania, Volvo or MAN six-cylinder diesels with Euro 5 or Euro 6 standards.
Gearboxes are manual, automated or automatic. On city routes, where frequent stops are made, an automatic box reduces driver fatigue but requires more maintenance time.
What to check when buying a used Irizar i4
Check the vehicle and transmission as thoroughly as you would any other bus of this make: the engine, gearbox, suspension, and brakes. Frequent stops quickly wear out the doors and braking system.
Inside, look for signs of corrosion around the door sills, the roof and window seals, the floor covering, and the seats. Used public transport buses often show signs of interior wear.
