Isuzu Citibus

The Citibus is a diesel bus that Anadolu Isuzu Otomotiv Sanayi ve Ticaret A.Ş. sells in Türkiye under the Isuzu name: the maker’s model page is headed “Isuzu Citibus” and its data page “ISUZU CITIBUS”. The figures on this page come from two Anadolu Isuzu documents in Turkish: the two-page Citibus brochure, whose second page carries the technical data (“TEKNİK ÖZELLİKLER”) and the equipment list (“DONANIM”) and whose PDF was created on 24 July 2026, and the Citibus model page on isuzu.com.tr, which carries no publication date and was read on 9 November 2026. Every figure is for the Turkish market.

Range and maker’s description

Anadolu Isuzu’s site lists the Citibus among its public transport (“Toplu Taşıma”) models, beside the Citiport range (see Isuzu Citiport), the Citivolt 12 (see Isuzu Citivolt 12) and the Novociti models (see Isuzu Novociti Volt).

The model page describes the Citibus as “Sınıfının en geniş ve en yüksek yolcu kapasitesine sahip otobüsü” (the bus with the widest and highest passenger capacity in its class) and adds “Üstelik 3. kapı standart” (a third door is standard as well). It says that with ABS (EBS) and ASR (EBS) braking systems, an auxiliary exhaust brake and retarder brake, and disc brakes front and rear, the Citibus provides safety for its driver and passengers.

The cover of the brochure carries the line “Anadolu Isuzu; Isuzu’nun Asya kıtası dışında bulunan tüm tesislerinde, IMM sertifikasına sahip tek fabrikasıdır”: Anadolu Isuzu describes its plant as the only factory among all of Isuzu’s facilities outside the Asian continent that holds IMM certification. No document opened gives the year the Citibus was introduced or describes an earlier version.
