CAT has officially announced introduction of the new 15L CT15 engine which will be offered together with the CT11 and CT13 units for the CT660 heavy duty truck. The new engine develops a maximum output of 550 hp with a peak torque of 1,850 lbs.-ft achieved at 2100 rpm.
To be able to offer these superior performances, the engine uses sequential turbochargers and a high pressure common rail fuel system. Moreover, interstage cooling between turbochargers increases air density to maintain power as speeds increase. The CT15 uses an EGR system to reduce the emissions and meets EPA 2010 requirements without the need of additives (AdBlue).
The engine is perfectly suited for heavy haul operations as it offers a massive pulling power from relatively low revs.
George Taylor, director of the Caterpillar Global On-Highway Truck Group said, “The CT15 engine is the perfect power solution for heavy-duty applications and extreme environments. Cat vocational truck customers can count on the CT15 for years of reliable, durable operation, which translates into a longer-lasting truck and higher resale value.”
The new CAT CT15 engine is also offered with a capable engine brake than provides a retarding power of up to 600 hp being among the strongest in this class. Besides improving the stopping power, the engine brake also keeps the use of service brakes to minimum.
CAT has a long history behind and the company is famous thanks o its strong engines and the heavy duty working vehicles that were designed to tackle the harshest construction sites without thinking twice. Recently, the company decided to try its luck in the transport industry and allied with Navistar to launch its first highway truck.
At the moment, the CAT CT630 is sold mainly on the Australian market and was developed especially for highway operations. Except for a few small differences, the truck shares the same design with the International ProStar, but is powered by a CAT C15 engine which develops 550hp. The CT630 also features a roomy cabin and an aerodynamic exterior design that was developed to enhance its fuel efficiency.
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.
The CT660 model is the first vocational truck built by Cat for the American market. Caterpillar has already a solid experience in building construction equipment and despite the fact that many people still consider its new model just an International with a new hood and another badge, the CT660 is able to make a compelling case for itself.
Available with a wide range of specifications, it can be configured to match almost any vocational application required as it’s ready to go head to head with the toughest jobs as a dump truck, concrete mixer, waste carrier or all-around heavy hauler.
The truck is priced at $157000 and is offered with a choice of two CAT CT engines based on MaxxForce units which develop between 330 – 475 hp.
