Mercedes-Benz » Econic III
That the new Econic has quite a number of important other innovations apart from the environmentally acceptable high performance Euro VI engines can be seen at first glance by the modern design of the low entry cab – the heart of the Econic concept. The spacious cab with its ergonomic entry and exit has been rigorously upgraded with a much more advanced design to make working a great deal more efficient. There are also innovations on the chassis – the wide range of chassis versions allow the Econic to be used for a very wide variety of applications. The new arrangement of the power units behind the cab as well as other alterations to the frame makes mounting bodies easier. Despite the increased weight or additional Euro VI components it has been possible to retain the payload as it was up to now by weight-saving measures on chassis and frame.
Altogether the Econic is a completely new vehicle with the exception of the time-tried bodyshell of the cab. At the very first glance it is quite clear that the new Econic is a member of the new Mercedes-Benz truck family. The new radiator grille, the stronger bumpers and standard LED daytime running lamps identify the modern design of the Econic cab. The new arrangement immediately catches the eye when getting into the low entry cab, which could be retained despite the required additional vehicle components needed to comply with the new Euro VI emission standards.
Econic drivers and crew will really appreciate the new cab with its time-tried low entry and the unusually spacious working area it provides. The completely revised cockpit with its new multifunction steering wheel allowing the instrument cluster display and the radio to be reached even more easily, as well as the switches which can be individually assigned and placed, give the driver the best working conditions. Other highlights in the cab are the new arrangement of the air vents and the electric sunblind which give the cab a much better working atmosphere in combination with the better insulation of the cab and engine tunnel, and of course, obviously, the low entry with the fully-glazed bi fold door on the side away from the traffic.
The European emission standards Euro VI really mean no less than a reduction of emissions and particulate matter by a total of 90 percent in comparison with Euro V. An important role on the way there has been played by the design of the greatly improved cooling system which deals efficiently with the additional cooling needed by the exhaust gas recirculation. In addition to the exhaust gas recirculation within the engine, the exhaust gas is cleaned by the closed particulate matter filter, AdBlue injection and the SCR catalytic converter. The BlueTec 6 filter systems are integrated in an exhaust gas aftertreatment unit with automatic electronic controls which regulate the cleaning of the exhaust gas with a multitude of engine and work parameters as required.
Two six-cylinder, 7.7 l OM 936 LA engines are used in the Econic with a basic output of 220 kW (299 hp) and a peak performance of 260 kW (354 hp). The new in-line engines deserve best marks in their class straightaway for all aspects. Construction features such as the cam shaft with shrunk on cam, forged and bolted conrod as well as a crankshaft designed for the greatest rigidity make it quite clear: these engines have been designed for a long, successful and efficient working life.
One great challenge to engine and transmission during the day-to-day work of the Econic is the stop-and-go traffic encountered in inner cities. That is why the Econic drivetrain also includes the six-gear automatic Allison transmission used up to now – and there could hardly be a more pleasant way of winding one’s way through dense city traffic. The automatic transmission also proves its ability for instance during the frequent stops and starts, e.g. for waste collection.
Initially the Econic will be supplied with 4x2, 6x4 and 6x2/4 axle configurations, with electro hydraulically progressive steered leading and trailed axles in the permitted gross vehicle weights 18 and 26 tonnes. As an option, it is possible to order specially customised vehicles tailored to the customer’s requirements. The two and three-axle versions are also available with various wheelbases – from compact and manoeuvrable with a length of 3450 mm up to 5700 mm. The cab is also available with two different heights: high (1745 mm interior height) and low (1295 mm).
