In­ter­na­tional is back with bon­neted Prostar day cab and tip­per, ex­tended cab, and sleeper

In­ter­na­tional ’s tilt at re­turn­ing to Aus­tralian promi­nence will cen­tre on four Prostar ver­sions mar­keted through Iveco and re­lated deal­er­ships. Flagged by Nav­is­tar at the last Bris­bane Truck Show, the project, which is just short of two years in the mak­ing, made its of­fi­cial de­but this week with un­veil­ings to deal­ers and the in­dus­try me­dia.

“Hav­ing the In­ter­na­tional prod­uct added to our very ex­ten­sive prod­uct range al­ready, hav­ing the con­ven­tional 15-litre, is a real cap across our en­tire prod­uct range,” Iveco Aus­tralia and New Zealand MD Michael Jon­son says.

While the fi­nal deal­er­ship net­work setup was still be­ing fi­nalised at the time of the launch, Aus­tralia and New Zealand ex­ec­u­tive GM Ray Os­good of par­ent firm CNH In­dus­trial (CNHI) re­veals Iveco’s sis­ter deal­er­ships for CNHI agri­cul­ture-fo­cused Case IH will have a role, not just in sup­port but in help­ing give the brand’s re­turn a leg up.

Os­good says he men­tioned at the Case IH dealer con­ven­tion be­fore the launch that In­ter­na­tional was be­ing brought back “and that I thought it would be won­der­ful if all of the Case IH deal­ers had an In­ter­na­tional truck to de­liver their In­ter­na­tional Har­vester equip­ment on.

“So they trig­gered off on this idea as well and we will, hope­fully, be mov­ing a lot of trucks to our own sis­ter net­work.”

He also name- checked the 15-litre Cum­mins en­gine, say­ing it was “some­thing we haven’t had in our range”, and, with 100 trucks said to have been spread through about 70 deal­er­ships, he sug­gested that per­haps there were not enough.

On the sub­ject of out­lets, Iveco Aus­tralia dealer de­vel­op­ment man­ager Mat­teo Gam­baro says: “Our pref­er­ence

is to be­gin op­er­at­ing through a core group of deal­er­ships that meet our strin­gent re­quire­ments and then strate­gi­cally in­crease the net­work foot­print through the ap­point­ment of ad­di­tional deal­er­ships – these could be stand­alone In­ter­na­tional deal­er­ships and/or parts and ser­vice out­lets.”

“From a parts and ser­vice per­spec­tive, we’re also for­tu­nate that Iveco full-line deal­er­ships and ser­vice and parts out­lets al­ready have a thor­ough knowl­edge and un­der­stand­ing of much of the ProStar’s com­po­nen­try thanks to a num­ber of ex­ist­ing Iveco models fea­tur­ing Cum­mins, Hen­drick­son, Ea­ton and Mer­i­tor equip­ment, as well as their on­go­ing sup­port of the pre­vi­ous gen­er­a­tions of In­ter­na­tional prod­ucts.

“Fur­ther to this, I can con­firm that all In­ter­na­tional deal­ers will also be au­tho­rised Cum­mins deal­ers.

“We’re con­fi­dent that our ini­tial dealer ap­point­ments will be well po­si­tioned to suit the ma­jor­ity of ProStar buy­ers in metropoli­tan and ru­ral ar­eas, with this sup­port to only get bet­ter as the year pro­gresses.”

In­ter­na­tional’s lo­cal en­gi­neer­ing man­ager Adrian Wright noted that the launch pre­sen­ta­tion footage es­chewed North Amer­i­can im­ages for that of other coun­tries where higher weights, harsh con­di­tions and multi- com­bi­na­tions were com­pa­ra­ble with the Aus­tralian ex­pe­ri­ence.

The de­sign of the right-hand drive cab and aero­dy­namic front end and other in­no­va­tions for Aus­tralian con­di­tions were a joint US-Aus­tralian ef­fort. But Wright de­scribed the present it­er­a­tions as ‘Phase 1’.

“The com­bi­na­tion of the lat­est en­gine tech­nol­ogy from Cum­mins and su­pe­rior aero­dy­namic per­for­mance saw the pro­to­type re­turn some im­pres­sive fuel con­sump­tion fig­ures in lo­cal, real-world test­ing,” Wright says.

“Aero­dy­nam­ics makes a big dif­fer­ence to truck fuel ef­fi­ciency – about half of the fuel that the truck uses goes to­wards push­ing it through the air, so if you achieve a 10 per cent im­prove­ment in aero­dy­nam­ics this trans­lates to about a 5 per cent im­prove­ment in terms of fuel econ­omy.

“Com­pared to some more tra­di­tion­ally styled, flat-fronted ve­hi­cles, the ProStar is as much as 10 per cent more aero­dy­namic.

“Even run­ning some ba­sic num­bers, the fuel sav­ings – and there­fore cost sav­ings – that can be made over the life of the truck are enor­mous.”

Wright em­pha­sises the ve­hi­cle’s vis­i­bil­ity ad­van­tages helped by the nose de­sign and wrap­around wind­screen.

“The line of for­ward vi­sion for the driver onto the road ahead is un­ob­structed thanks to the slop­ing hood, lower-placed in­stru­ment panel and wrap­around wind­screen,” he says.

“The ProStar again boasts best-in- class per­for­mance in this area, com­par­ing very favourably to other con­ven­tional cabs and even cab- over trucks.”


All ve­hi­cles will be pow­ered by the lat­est E5 Cum­mins X15 SCR en­gine pro­duc­ing 550hp (410kW) and 1850lb-ft (2508 Nm) of torque.

It fea­tures high-pres­sure in­jec­tion and the Cum­mins Emis­sions So­lu­tions (CES) sys­tem to com­fort­ably meet Euro 5 emis­sions re­quire­ments.

Cool­ing is through an ‘Over and Un­der’ sys­tem with CAC above ra­di­a­tor and Hor­ton Drive­mas­ter air- op­er­ated 2-speed fan drive, en­sur­ing op­ti­mum per­for­mance in hot Aus­tralian con­di­tions.

Cou­pled to the en­gine is a choice of ei­ther an Ea­ton 18-speed man­ual or the Ea­ton Ul­traShift Plus 18-speed au­to­mated man­ual.

Power to the rear Mer­i­tor tan­dem axles is via a Dana Spicer SPL drive­shaft, and trac­tion is aided by power di­vider lock and cross locks on both rear-drive axles.

Up front, the models use Mer­i­tor MFS axles with alu­minium al­loy hubs for re­duced tare weight, while sus­pen­sion is three-leaf par­a­bolic ta­per­leaf with 6500kg ca­pac­ity.

Rear sus­pen­sion comes cour­tesy of a Hen­drick­son Pri­maax-EX Air Tan­dem setup with 20,900kg ca­pac­ity.

The day cab comes with a 4.3m wheel­base “which al­lows you to meet that crit­i­cal di­men­sion of 5.4 me­tres from the bumper to the cen­tre of the fifth wheel”.

“That means you can fit it in front of a B- dou­ble, B-triple and lots of PBS com­bi­na­tions,” Wright notes.

Bumper to back- of- cab lengths are 112 inches, 138 inches and 141 inches.

The tip­per wheel base is 5 me­tres and both are said to be suit­able for per­for­mance-based stan­dards. Gross ve­hi­cle mass and gross com­bi­na­tion mass are 24.5 tonnes and 90 tonnes re­spec­tively.


The ProStar fea­tures Bendix ABS brakes with au­to­matic trac­tion con­trol.

Trucks spec­i­fied with the Ul­traShift Plus trans­mis­sion are also equipped with hill­start aid. They can also ben­e­fit from the op­tional ‘ADEPT’ pack­age, a suite of in­no­va­tive elec­tronic fea­tures ca­pa­ble of fur­ther re­duc­ing fuel con­sump­tion by up to 6 per cent.

The sys­tem utilises load-, speed- and grade-sens­ing soft ware, mak­ing mi­nor ad­just­ments to speed, power and trans­mis­sion gear se­lec­tion to take ad­van­tage of ve­hi­cle mo­men­tum for bet­ter fuel econ­omy.

The ADEPT pack­age also in­cludes ‘SmartTorque2’ and ‘SmartCoast’ tech­nol­ogy.

SmartTorque2 is the next gen­er­a­tion of torque-man­age­ment tech­nol­ogy from Cum­mins. The sys­tem senses both the se­lected gear and over­all en­gine load as a re­sult of the gross ve­hi­cle weight, aero­dy­namic drag and road grade.

All models come stan­dard with a park brake warn­ing alarm that sounds if the key is off and the driver’s door is opened with­out the park brake be­ing ap­plied.

The trucks have dual, pol­ished alu­minium fuel tanks with 720 litres to­tal vol­ume – al­ter­na­tive fuel tank op­tions are avail­able to meet spe­cific ap­pli­ca­tions. The AdBlue tank is 90 litres.

The models fea­ture front un­der-run pro­tec­tion and LED head­lamps with

in­te­grated day­time run­ning lamps for added vis­i­bil­ity dur­ing day or night. FOR­EIGN CON­TIN­GENT In at­ten­dance from Nav­is­tar were vice pres­i­dent – global ex­port Fed­erico Palomo, di­rec­tor of sales Dicky Com­man­deur, chief en­gi­neer Marco Anaya, and di­rec­tor of mar­ket­ing and strat­egy Oc­tavio Gon­za­lez.

“The re­turn of In­ter­na­tional to Aus­tralia has been ea­gerly awaited, es­pe­cially given the high stand­ing the brand en­joys here cour­tesy of ear­lier models and a very long and suc­cess­ful pedi­gree,” Palomo says.

“These his­tor­i­cal as­pects aside, we also know that prospec­tive cus­tomers in Aus­tralia are also ex­tremely ex­cited by the out­stand­ing fea­tures and ben­e­fits that the new ProStar models will de­liver to their op­er­a­tions.

“There was an ob­vi­ous gap in the lo­cal mar­ket for a high- qual­ity and ver­sa­tile yet af­ford­able North Amer­i­can-style truck that could get the tough jobs done with a min­i­mum of fuss.”
