Stralis : the heavy specialists

The evolving market, customers’ needs and environmental demands: Iveco has always taken all this into consideration when it designs its vehicles. They are elements that have played an important role in the development of the Stralis range, which introduces a number of important innovations in 2007.

The entire heavy range can boast the same features of safety, design and comfort, and all the vehicles are equipped with Cursor engines, the benchmark in terms of reliability, low consumption, and high torque power.



Designed to improve comfort and productivity at the same time, the vehicles in the Stralis Active Day and Active Time range offer the best of everything to their owners: modern, functional styling combined with excellent performance and reliability. The new range stands out for the restyled cab exterior and the new features inside. Both versions are powered by Curser 8 and 10 engines that already meet the Euro 5 emissions standards, well ahead of the 2009 deadline.


Innovation in the cab

The features on the Stralis Active Time and Active Day  begin on the outside, because the new cabs share the innovations created for the Active Space3 flagship: a new grille, new bumpers and an innovative look for the front light clusters. Inside, a new colour range enhances the styling of the vehicles, confirming that the Stralis AT and AD offer a functional working environment that is also comfortable and relaxing.

Available in tractor and rigid versions, the Stralis AT cab is available in two configurations, both with double bunks: with a Standard Roof, or with a High Roof, replacing the medium on request.

The Stralis AD has a new cab with a standard Roof, which stands out for the captivating design of a number of exterior elements such as the front grille, bumpers and light clusters.

 Driveline

On the Stralis Active Time and Active Day, the driveline, is perfectly integrated with the Cursor engines, the EuroTronic automatic transmission and the Allison automatic transmission, to guarantee optimal performance and low fuel consumption.


Engine

The Cursor engines are the heart of the Stralis. They are powerful and reliable, designed to guarantee excellent performance and low running costs, as well as superior comfort on the road. They are available in different versions, the Cursor 8 delivering 310, 330 and 360 Hp and the Cursor 10 delivering 420 and 450 Hp. The combination of cutting edge engineering and electronics makes these engines a benchmark in terms of performance, consumption, maintenance costs and durability.

Gearboxes

The range of gearboxes offered on the Stralis Active Time and Active Day are the 12-speed automated units and Allison automatics.

Front and rear axles
The Arvin Meritor rear axles were designed to meet all the needs of heavy road transport. Renowned for their exceptional resistance and low maintenance, they are available in simple and double reduction versions to guarantee maximum reliability even for the most demanding missions. The front axle has a steering lock of 52°, which is a great advantage for anyone in the delivery business.

There is a wide range of rear axle ratios that are suitable when travelling fully laden on motorways and main roads: long ratios are recommended on level terrain, with medium loads and for less difficult missions, while “shorter” ratios are suitable for more demanding routes where more traction is required, such as mountain routes or with a full load.

The chassis

The sturdiness and ease of bodying of the chassis, the reliability of the braking system fitted with innovative electronic devices that help in emergency conditions, the outstanding flexibility of the air and mechanical suspension, and the cutting-edge technology of the electronic systems make the Stralis an extraordinarily efficient vehicle, that guarantees optimal performance on all types of route.

Frame

All versions share the well-known characteristics of reliability and sturdiness that have made Iveco frames famous. Built with double-bottleneck U-section long members of Fe F 490 high yield steel, the Stralis AS3 is offered with two different types of frame, depending on the mission. For road use, the Stralis adopts a frame that is 6.7 mm thick, which is easily bodied. For more demanding applications, i.e. HM (Heavy Mission 6x4) versions, the frame thickness is 7.7 mm. The 6x2 chassis-cabs with wheelbases above 5,700 mm also use these same dimensions.

The Stralis comes in a wide choice of wheelbases and body lengths, and two or three axles, with all the advantages of a flat, uncluttered frame that poses no limits even for the most specialist body and equipment.

The Suspension

To respond to the needs of all its customers, the Stralis is offered with different types of suspension, steel with parabolic or air springs, so that it can tackle different types of terrain and load. Trucks destined to carry containers are fitted with special all-round air suspension with five front struts, which guarantee rapid excursion of almost 30 cm.

Throughout the Stralis range, there are models that fit rear air suspension with four air cushions and a trim adjustment system, to eliminate pitching and rolling, enhancing comfort and stability. For high cube transport, there is a low loader version with all-round air suspension and low profile tyres.

All the air suspension systems are fitted with the ECAS (Electronically controlled air suspension) system, which keeps the chassis height constant, raising and lowering the system rapidly and memorising different levels.

Equipped with electronic devices that come into play in emergency situations, the Stralis range tops the market in terms of active safety, boasting excellent performance, both for road behaviour and for braking.

Brake

The Cursor engines offer a decompression brake (the Iveco Turbo Brake), which increases the efficiency of the braking when it is used in conjuction with the variable geometry turbo. The force of the engine brake guarantees maximum safety downhill, making it less necessary to use the service brake, also saving on brake pad and disc wear.

All the Stralis vehicles are fitted with disc brakes at the front and rear, controlled electronically by the EBS (Electronic Braking System) control unit which governs the ABS (Antilock Braking System), ASR (Anti Slip Regulation) and EBL (Electronic Brake force Limitation) functions, backing up the engine brake and the Intarder which are activated automatically to minimise service brake wear and to decelerate the vehicle in a manner suited to the driving conditions.

Onboard electronics
All the cabling on the Stralis, in the cab and on the chassis, adopts CAN-Bus architecture and Multiplex technology: a solution that allows all the control units of the main component and sensors on the vehicle to dialogue reliably and extremely efficiently. Instead of a cable where a single electrical impulse passes, the Stralis uses cables with Multiplex logic which can send multiple signals simultaneously. The reduction in the number of cables (-45%) and connection points which translates into greater reliability of the electrical system, provides a clean layout on the chassis, and an increase in serviceability.

The CAN system also makes it possible to perform rapid, effective diagnosis (thus reducing down time in the workshop) and manages a series of functions electronically, such as control of the engine (which thus enhances the already excellent fuel consumption figures) and the EBS braking system, or the operation of the display and steering wheel controls.

The Stralis is equipped with the FMS (Fleet Management System), a very useful application which acts as a protected interface between the vehicle’s Multiplex system and the onboard computer, optimising fleet management by collecting, processing and analysing data regarding the vehicle and driving conditions.
