In US, CAT sells only its CT660 vocational model, but in Australia its lineup includes two models namely the CT 610 and CT 630. Both Australian models were developed by NC2, a joint venture between Navistar and Caterpillar and you won’t need to be an expert to see that between CAT’s trucks and International’s models there is a strong resemblance.
While the CT660 has a totally fresh design the 610 model is based on the International DuraStar and TranStar models. These vehicles don’t share only the exterior design, but also the same interior and technologies. However, the CT610 isn’t powered by Cummins engines, as at its hart sits a 470 hp CAT engine. The CT610 is as versatile as its International siblings and was developed especially for regional haul applications.
