Iveco Stralis

The Stralis is the heavy on-road truck range of Iveco S.p.A. of Turin. Iveco’s 2007 press kit describes it as a work tool for heavy road transport “dalle 19 alle 44 tonnellate”, from 19 to 44 tonnes, and says the range was presented in 2002 and that the Stralis AS was named “Truck of the Year 2003”. This page is built from Iveco’s own press documents: the 2007 press kit for the new Stralis (Italian and French editions, undated), the press kit for the IAA 2010 show in Hanover, the Stralis Hi-Way press kit dated Turin, 1 July 2012, the IAA 2012 press kit, a release on the Hi-Way cabin dated 12 September 2013, the Stralis XP and Stralis NP releases dated Madrid, 14 June 2016, and the IVECO S-WAY launch release of 2 July 2019.

Generations in Iveco’s documents

• 2002. The 2007 press kit says the Stralis range was presented in 2002 and that the Stralis AS was named “Truck of the Year 2003”.
• 2007. The press kit for the new Stralis says its main novelty is the cab, offered as Active Day, Active Time and the new Active Space (AS3), and gives Cursor Euro 5 engines with SCR. It calls the AS3 “il top della gamma Stralis 2007”, the top of the 2007 Stralis range.
• 2010. At the IAA in Hanover Iveco gave a world preview of the ECOSTRALIS, a long-haul Stralis with a specific calibration of its control units for lower fuel consumption, constant tyre-pressure monitoring and attention to the aerodynamics of the whole vehicle, offered with services including an economical-driving course and the Blue&Me Fleet system. The same kit calls the Stralis “l’ammiraglia Iveco”, Iveco’s flagship.
• 1 July 2012. Iveco presented the Stralis Hi-Way, “l’ultima generazione di veicoli della gamma heavy-duty”, with Euro VI engines using FPT Industrial’s HI-eSCR system, new Hi-Way, Hi-Road and Hi-Street cabs and new safety systems. The kit says the vehicle is built at Iveco’s Madrid plant and that the new generation went through more than 6 million km of endurance testing and more than 11 million km of road testing, with 40% more quality checks in production than the previous version.
• September 2012. At the IAA in Hanover, 20 to 27 September 2012, Iveco added a 400 hp Cursor 9 and a 480 hp Cursor 11 to the Euro VI line-up and showed the Stralis LNG, which the kit says had been marketed throughout Europe from that year. Iveco’s cabin release of 2013 says the Stralis Hi-Way was named the 2013 International Truck of the Year at the Hanover show.
• 14 June 2016. In Madrid Iveco launched the New Stralis XP, which its release says “builds on the solid foundation of the Stralis Hi-Way”, with a renewed driveline, new electrical and electronic systems, a new transmission, rear axle and rear suspension and a re-engineered engine, and the New Stralis NP, a natural-gas truck for long-haul work.
• 2 July 2019. Iveco launched the IVECO S-WAY in Madrid as “the first vehicle in the new IVECO WAY heavy range”; the release says it “carries over all the advances introduced in the previous generations and adds a new cab”. Its company profile lists Iveco’s heavy segment above 16 tons as the Trakker and the IVECO WAY range with the S-WAY and the X-WAY, where the profile in the June 2016 releases had listed “the Trakker (dedicated to off-road missions) and the Stralis, both over 16 tons”. The 2019 release does not use the name Stralis. The Iveco S-Way and the light off-road Iveco X-Way have their own pages.

The 2007 Stralis

The 2007 press kit builds the range from three engines of 8, 10 and 13 litres, three cabs and three roof heights, low, medium and high, and speaks of more than 500 versions in 4x2, 6x2 and 6x4 form. The starting configurations it lists are 4x2 tractors, with a low version (Low Tractor), a double-reduction rear axle version (HR) and a reinforced-chassis version (RR); 6x2 tractors with a steered centre axle; 4x2 rigids on mechanical or air suspension; 6x2 rigids with a single- or twin-wheel third axle that is liftable, fixed or steered, or steered and in the centre position, on rear or full air suspension; and 6x4 tractors and rigids. High-travel air suspension adapts the vehicle to the height that distribution or intermodal work requires.

Active cabs

• Active Day, a short cab with a low roof, for medium-distance, urban and suburban work without overnight stops.
• Active Time, a long cab with a low or high roof, for medium and long national or international distances.
• Active Space (AS3), the top of the range, named for its interior space, with dimensions that make the cab “praticamente cubica”, practically cubic; it is also offered with a low roof. Iveco gives the high-roof AS3 95 mm more height, 90 mm more depth and 1.8 m³ more volume.

The slatted bunks measure 746 x 2,020 mm (lower) and 784 x 1,940 mm (upper); the upper bunk tilts open on air springs and is reached by an aluminium ladder. The lower bunk comes in three layouts: three modules with a table in the centre module, three modules taking in the passenger seat, or a single module combined with a 100-litre sliding container next to the fridge. The folding table measures 580 x 545 mm, 30% more surface than before; usable storage volume is up by 15%, and the central compartment measures 450 x 780 mm against 220 x 595 mm on the previous model. Outside, an electrically opened side locker with doors 60% larger than on the previous Stralis and an under-cab locker on both sides give a total of 480 litres of storage. Iveco says the drag coefficient (Cx) improved by 2% despite the larger roof. The driver’s seat is an air-suspended seat with four degrees of freedom and 220 mm of travel, 40 mm more than before; on the AS3 the central multifunction instrument panel has a colour display.

The 2007 line-up

The cab codes in the same tables are AD-N (low roof), AT-N (low and medium roof) and AS3-L (low and high roof), and every page carries the footnote “configurations may vary in accordance with specific models’ features”. The IAA 2010 kit adds two special versions shown at the show: the Stralis AT 440S36T/P SL, designed for payload-sensitive work such as liquid transport, and the Stralis AS 260S42Y/FS-CM, prepared by Saxas for demountable bodies.

Cursor engines of the Euro 5 range

The 2007 kit describes the Cursor Euro 5 engines as SCR engines with unit injectors at up to 2,000 bar, an overhead camshaft, four valves per cylinder, a “sotto-blocco e testa cilindri mono-blocco” (lower block and one-piece cylinder head) for rigidity, a decompression engine brake, electronic control of injection timing and quantity for each cylinder, and a variable-geometry turbocharger. It gives 310 to 560 hp and peak torques of 1,300 to 2,500 Nm across the three families. Its engine table lists the Cursor 8 at 7,790 cc and a dry weight of 680 kg, the Cursor 10 at 10,300 cc and 932 kg and the Cursor 13 at 12,880 cc and 1,006 kg. The 2012 Hi-Way kit describes all the Cursor engines as inline six-cylinders. By Iveco’s account the Euro 5 engines use 2 to 5% less fuel than the Euro 3 versions, and oil-change intervals are 150,000 km.

The IAA 2010 press kit gives the ratings in one table, which names no emission class:

The table prints the power speeds of the 500 and 560 hp ratings as 2080 – 1900 and 2050 – 1900. The 2007 line-up tables give the two Cursor 10 ratings as 309 kW (420 hp) and 331 kW (450 hp), the 2010 table as 310 and 330 kW. The 480 hp Cursor 13 is in the 2010 table and not in the 2007 kit. How power and torque figures are stated is set out in reading truck power figures.

Stralis Hi-Way (2012): Euro VI engines and HI-eSCR

The Hi-Way kit of July 2012 gives the Stralis FPT Industrial Cursor engines in three displacements for each emission range, 8, 10 and 13 litres for Euro V and 9, 11 and 13 litres for Euro VI, with eight diesel ratings from 310 to 560 hp and three CNG versions from 270 to 330 hp. At the IAA in September 2012 Iveco added two Euro VI ratings: 400 hp with 1,700 Nm from the Cursor 9, for fuel-transport vehicles, and 480 hp with 2,250 Nm from the Cursor 11, which Iveco says matches the performance of a 13-litre engine with lower weight and fuel consumption. Neither kit gives a kilowatt figure for a Euro VI rating.

The Euro VI engines have common-rail injection at up to 2,200 bar, a new engine control unit that also manages the SCR system and the particulate filter, and variable-geometry turbochargers on the highest torques. Iveco gives maximum torque from 1,000 rpm, fuel tanks of up to 1,400 litres and service intervals of up to 150,000 km. Every engine has a decompression engine brake; on the Euro VI engines an exhaust throttle valve raises the performance of the Super Engine Brake (SEB) by up to 30% against the Euro V engines, and the engine brake works with the service brakes and the Intarder hydraulic retarder.

Euro VI is met without exhaust-gas recirculation. FPT Industrial’s patented HI-eSCR system, which Iveco calls High Efficiency SCR, reduces nitrogen oxides “di oltre il 95%”, by more than 95%, and consists of a diesel oxidation catalyst (DOC), a passive diesel particulate filter (DPF), an AdBlue dosing module, an AdBlue mixer, the selective catalytic reduction (SCR) catalyst and a clean-up catalyst (CUC), with sensors for nitrogen oxides and excess ammonia (NH3). The kit says forced regeneration of the filter is not needed, and that because the engine needs no extra cooling the Hi-Way keeps the body in white of the existing cab. How SCR and AdBlue work and what the Euro VI standard requires are covered separately. Iveco claims fuel savings of up to 10%, and up to 4% lower total cost of ownership on an international mission run by a Stralis Hi-Way tractor.

Hi-Way, Hi-Road and Hi-Street cabs

The 2012 cab range comes in two widths. The wide Hi-Way cab, 2,500 mm, is a long cab with a high or low roof for long-haul work; the medium cab, 2,300 mm, is the long Hi-Road with a medium-high or low roof and the short Hi-Street with a low roof. The high-roof Hi-Way has more than 10 m³ of interior space. Inside it has a new dashboard, and the kit lists a new ventilated and heated seat with an integrated height-adjustable seat belt as available. The cab has a steering wheel with telephone controls, a lower “High comfort” bunk 80 cm wide and more than two metres long on wooden slats with a reclining backrest, or a bunk that folds into a table, and in the high-roof version an upper bunk that opens on air springs and folds away into the wall. A roof-integrated auxiliary air conditioner that works with the engine off is available, and a maxi-fridge of more than 50 litres can be fitted. The Hi-Road and Hi-Street have a redesigned symmetrical dashboard.

Outside, the new front has a redesigned central grille and corner panels, a sun visor with LED lights, LED daytime running lights and xenon headlamps; Iveco says the drag coefficient (Cx) improved by 3%. The IVECONNECT system combines infotainment, navigation, the Driving Style Evaluation function, the Driver Attention Support and fleet management on a 7-inch touchscreen in the dashboard.

Iveco’s release of 12 September 2013 lists options and Iveco Shop accessories for the Hi-Way cabin: the Hi-Sound audio system with 520 watt speakers, 700 watt amplifiers and subwoofers of up to 400 watts, a Hi-Vision kit made with Blaupunkt with a 19-inch LCD TV, the Around View 360 system with four cameras and a 7-inch monitor, an alarm system with call alert, a roof air conditioner for use when the truck is stationary, a 50-litre maxi-fridge and a Lavazza espresso machine orderable from September 2013. It gives the driver bunk as 80 centimetres wide and two metres long with a nine-centimetre mattress.

Gearboxes, axles, chassis and suspension

The 2007 kit lists ZF manual gearboxes with 9 or 16 speeds and Servoshift assistance, Allison automatics for stop-and-go work and the 12-speed EuroTronic automated gearbox: the 9-speed 9S1310TO and the EuroTronic 12AS1420TD on the 310 and 330 hp Cursor 8, and the 16-speed manual also on the 560 hp Cursor 13. Rear axles are by Arvin Meritor and Iveco, in single- and double-reduction versions. The side members have a double bottleneck and a U section, with riveted cross members, in Fe E 490 high-yield steel 6.7 to 7.7 mm thick, and the wiring uses CAN-bus and Multiplex technology with 45% fewer cables.

The 2012 Hi-Way kit offers a manual gearbox with 9 or 16 speeds, the ZF EuroTronic 12-speed automated gearbox with its lever on the steering column, and a 6-speed Allison automatic; from the Euro VI vehicles on, the manuals have a single-H shift. The Intarder is available on manual and automated gearboxes. Front axles are rated at up to 9 tonnes and the standard single-reduction rear axles at up to 13 tonnes; differential locks and double-reduction axles (central and hub reduction) are available, with axle ratios from 2.64 to 5.29. The range also includes three- and four-axle vehicles with fixed or liftable, rigid or steered axles on single or twin wheels. The frame is a double-bottleneck C-section in high-yield steel, 6.7 or 7.7 mm thick by wheelbase and version, and the suspension is parabolic, rear air or full air, the air suspensions with ECAS electronically controlled air suspension.

The 2016 Stralis XP release lists the new 12-speed HI-TRONIX automated transmission and a longer 2.47 rear axle ratio, which lowers engine speed by 7%, according to Iveco.

Brakes, safety and driver assistance

In the 2007 kit the whole Stralis range has ventilated disc brakes with EBS as standard and the Iveco Turbo Brake decompression engine brake; ESP is available on the whole range, together with the Hill Holder, Adaptive Cruise Control (ACC) and the Lane Departure Warning System. The ZF Intarder of the second generation is offered for routes with steep gradients.

The 2012 Hi-Way kit lists EBS with a Brake Assistant function and integrated ABS, ASR and EBL; ESP; the Hill Holder, which holds the vehicle for a few seconds on a hill start; ACC, which brings in the engine brake, the Intarder and the service brakes automatically; the Advanced Emergency Braking System (AEBS), available from the Euro VI vehicles on; the Lane Departure Warning System; the Driver Attention Support, which monitors steering movements; xenon headlamps; and daytime running lights with xenon or conventional headlamps.

Natural gas versions

The IAA 2010 kit shows two CNG Stralis with ZF 16S1621 gearboxes and the Intarder: an AD 260S27Y/FS CNG in 6x2x4 configuration on air suspension on all three axles, with the first and third axles steered and 640 litres of CNG cylinders, and an AD 440S27T/P CNG tractor for temperature-controlled urban distribution with 720 litres of CNG.

The IAA 2012 kit describes the Stralis LNG, in which the liquefied natural gas is stored liquid at −125 °C in cryogenic tanks and reaches the engine as a gas after a heat exchanger. The tractor at the show was a 4x2 for 40-tonne GCW work with a 330 hp natural-gas Cursor 8, a manual gearbox, the Intarder and EBS as standard. Iveco gives the noise of its natural-gas Stralis as 3 to 6 decibels lower on average than that of a diesel of the same power.

The New Stralis NP of 14 June 2016 has the 8.7-litre Iveco Cursor 9 Natural Gas Euro VI engine with 400 hp and 1,700 Nm, which Iveco says equals its diesel equivalent, a stoichiometric engine with a new high-flow three-way catalyst. It runs on CNG or LNG, and Iveco calls it the first natural-gas truck with a 12-speed automated gearbox. The LNG-only version has a range of 1,500 km by Iveco’s figure. The after-treatment needs no AdBlue, no particulate filter and no active regeneration, and an integrated hydraulic retarder, the hill holder and ACC are standard. The NP has the Hi-Way cab, given as about 2 metres high inside with a volume of over 10 cubic metres and one or two beds.

Stralis XP (2016)

The New Stralis XP of 14 June 2016 carries over the Hi-Way cab and the HI-SCR Euro VI system, which Iveco says requires no regeneration. Its standard fuel-saving features include Smart Auxiliaries that switch off or go into energy-saving mode when not needed and the predictive GPS-based Hi-Cruise system controlling eco-roll, gearshifting and cruise control; the release names them together with the 12-speed HI-TRONIX automated transmission, the EcoSwitch speed and torque limiter, the optimised rear-axle ratio and low-rolling-resistance tyres developed by Michelin. The 480XP and 570XP, for extra-long-haul work, add Smart EGR, which recirculates 8% of the exhaust gas to allow an earlier start of injection, in combination with HI-SCR at a 97% tailpipe NOx conversion. Iveco claims fuel savings of up to 11% from the vehicle and up to 3% more from its services, and a 5.6% lower total cost of ownership in long-haul work.

Source notes

The engine rows are the Stralis table of Iveco’s IAA 2010 press kit, with the displacements of the 2007 press kit; the table heads the power column CV (km) and prints the power speeds of the 500 and 560 hp Cursor 13 ratings as 2080 – 1900 and 2050 – 1900 rpm. The 2007 line-up tables give the two Cursor 10 ratings as 309/420 and 331/450 kW/cv, the 2010 table as 420 (310) and 450 (330). The Euro VI engines of the 2012 Stralis Hi-Way, the 9, 11 and 13 litre Cursors, have no row because the documents opened rate them in CV only: 400 CV with 1,700 Nm for the Cursor 9 and 480 CV with 2,250 Nm for the Cursor 11. The same applies to the 8.7 litre Cursor 9 Natural Gas of the 2016 Stralis NP, 400 hp with 1,700 Nm. The 44 t is the GCW of every tractor in the 2007 line-up tables; the rigids are given at 19 t GVW as 4x2 and 26 t as 6x2 and 6x4, and the range as a whole at 19 to 44 tonnes. The cab widths are those of the 2012 Stralis Hi-Way press kit. No document opened gives a start or an end of production: the 2007 press kit says the range was presented in 2002, and the IVECO S-WAY launch release of 2 July 2019 does not name the Stralis.
