The Stralis Active Space cab: new inside and out TextCenterThe new Active Space cab, based on the structural body of the existing EuroStar cab, has a completely new exterior and interior, which contribute to the aerodynamics, image, fittings of the driving position and rest area. Styling which cuts fuel costs The exterior of the Stralis cab has been designed to guarantee optimum airflow: the corners of the cab front and bumpers are more rounded, as is the front of the high roof. The flowing lines are the result of research into aerodynamics and give the Stralis a modern, streamlined look. The big lateral deflectors channel the flow of air towards the side of the cab and effectively protect the side windows, mirrors and door handles from mud coming up off the front wheels. The outsize grille means increased air flow to the radiator. Trials in the wind tunnel have helped shape the general outline of the cab, as well as a few details, such as the sun visor, the moulded raised roof and aerodynamic elements between the cab and bodywork, and between the cab and semitrailer. When the Active Space cab is teamed with a trailer the raised roof comes with a standard built-in adjustable deflector. For tractors Iveco offers a three-dimensional deflector with an upper adjustable part and two side fenders. The left-hand side fender is adjustable to provide access to the catwalk. In this way the cab and bodywork (of the truck or semitrailer) are completely streamlined, up to an exterior height of four metres. The improved aerodynamics mean less wind resistance, and consequently lower fuel consumption, with maximum efficiency at cruising speed, statistically proven to be the most frequent operating speed. Design and functionality Research into aerodynamics came up with a fluid outline, but left a certain amount of freedom as to styling. Iveco wanted the new range to have a powerful image, without resorting to overly aggressive elements, and at the same time to create a feeling of comfort, as well as looking good on the road. And with its roots in the land of vehicle design Iveco also had to give a touch of class to products which would be conveying its clients’ image too. The famous design studio Garnero worked together with Iveco technicians and designers. MoreContentHtmlGreater engine-cooling power Compared to the EuroStar, the surface of the liquid coolant in the radiator has increased from 68 to 84 dm2 (+23%), while the intercooler has gone up from 47 to 57 dm2 (+21%). These changes achieve three things. They reduce fan-operating times and cool the air in the engine in order to limit the maximum temperature of combustion. (reducing polluting emissions causes a substantial increase in temperature) Meaning the amount of energy absorbed by the braking system on the transmission is dispersed through the liquid coolant, making for more efficient braking. The air feed to the radiator is aided by the new frontal area of the Active Space cab and by the layout of the pipes and various controls behind the grille. The fan has also been given a new electronic coupling, which makes for a more gradual insertion and intermediate rotation speeds, which are slower than the engine. Iveco engineers estimate that the new cooling system means a 1.5% saving on fuel. A flexible net in front of the radiator cuts down the risk of insects entering the pipes and blocking them, and the net can be removed for cleaning. Advanced comfort The new four point air suspension with shock absorbers and anti-roll bar means enhanced comfort, thanks to a more efficient absorption of variations from the road surface and the semitrailer, as well as a lower oscillation frequency. The cab tips up to an angle of 72° without having to open the front grille thanks to a hydraulic cylinder, which is actioned by a standard electric pump. Two lateral storage compartments, which are accessible from the outside of the cab, can also be opened from inside the cab. They provide perfect storage space for all the driver’s work equipment (gloves, safety shoes etc), and as they are separate from the cab no unpleasant odours come through. Three equidistant anti-slip steps provide access to the cab. Air from the engine is aspirated via a flat pipe situated at the back left of the cab.
