The Stralis tractors join the company's fleet of more than 100 commercial vehicles and initial feedback has been "good".
"We had heard good reports of the Stralis Hi-Way so were keen to run our own evaluation," states managing director Bill Hockin.
"Initial reports have been encouraging with good results on the fuel front, even when taking into account that the vehicles are still new," he continues.
"We carry out all our own maintenance, and operations to date have been trouble free.... Coupled with positive comments from the drivers, it's made for a very encouraging start."
Each of his Stralis tractor units was specified with the Cursor 11 460bhp engine (which delivers 2,150 Nm of torque between 925 and 1,500rpm) matched with Iveco's standard EuroTronic (ZF) automated transmission.
Efficiency should be good, since the Stralis Hi-Way has Iveco's patented HI-SCR (selective catalytic reduction) system, which meets Euro 6 emissions standards without exhaust gas recirculation (EGR).
Iveco makes the point that, as a result, there is no requirement for increased engine cooling capacity, nor for active regeneration in the DPF (diesel particulate filter).
This helps to deliver weight reduction and impressive fuel performance, says the firm, while the simplicity of the SCR-only approach means long service intervals for the DPF of up to 600,000km.
"As the vehicles get more miles under their belt we will be better placed to evaluate the total cost of ownership," comments Hockin.
"That's the number one consideration when running a large heavy truck fleet as intensively as we do, and was the key driver in us ordering our first Iveco vehicles."
Delivered by dealer Hendy Van & Truck, the new vehicles will trunk more than 130,000 km per year operating with a mix of curtainsiders, flatbeds and tankers.
