A Mercedes modellek aerodinamikája már napjainkban is kiemelkedőnek számít ám a német gyártó legújabb koncepció modellje még feljebb emeli a lécet egy olyan jármű képében, mely 80 km/h felett különböző pontokon megváltoztatja külső formáját. A mai S osztály jövőjét sejtető jármű a világon egyedüláll&oacut
A javított aerodinamika természetesen kedvező hatással van a fogyasztásra is és pusztán ennek az alakváltásnak köszönhetően 3 g/km-el kevesebb az autó CO2 kibocsátása és az elektromos üzemmód hatótávolsága is 4 km-el megnőtt. A különleges Mercedes belső kialakítási is futurisztikus és a Tesla S modelljéhez hasonlóan mindenfelé érintő képernyők találhatók a már-már űrhajóra emlékeztető belső térben.
Mercedes-Benz “Concept IAA”: digital transformer.
Two cars in one.
The Mercedes-Benz “Concept IAA” (Intelligent Aerodynamic Automobile) is two cars in one: an aerodynamics world champion with a Cd value of 0.19 and a four-door coupé embodying irresistible design. The study, which is celebrating its world premiere at the IAA Cars 2015, switches automatically from design mode to aerodynamic mode when the vehicle reaches a speed of 80 km/h, whereby numerous aerodynamics measures alter the shape of the vehicle. Inside, the “Concept IAA” continues the design line of the S-Class and S-Class Coupé and offers new touch-based functions.
Fascinating transformation.
At the touch of a button, or automatically on reaching a speed of 80 km/h, the Mercedes-Benz “Concept IAA” performs a fascinating transformation in which the captivatingly beautiful four-door coupé turns into an aerodynamics world champion: eight segments extend at the rear, increasing its length by up to 390 millimetres; front flaps in the front bumper extend by 25 millimetres to the front and 20 millimetres to the rear, improving the air flow around the front end and the front wheel arches; the Active Rims alter their cupping from 55 millimetres to zero; and the louvre in the front bumper moves 60 millimetres to the rear, improving the underbody air flow. “The “Concept IAA” applies intelligent innovations to resolve the conflicting aims of functionality and aesthetics and shows that we still have plenty of ideas on how to achieve further improvements in efficiency,” says Prof. Dr Thomas Weber, Member of the Daimler Board of Management responsible for Group Research and Head of Mercedes-Benz Cars Development.
Systematic digital networking.
Equally, the “Concept IAA” exemplifies the fundamental technological changes which are taking place in the automotive industry. The primary driving force behind this process of change is digitisation – buzzword: Industry 4.0. For Mercedes-Benz, a continuous digital process chain from research and development through production to marketing and sales, logistics and the service area is already becoming reality. The design and aerodynamic shaping of the “Concept IAA” would not have been possible without the systematic digital networking of different specialist departments. The designers have employed the latest algorithmic design methods to handle the complex geometric design. The individually adapted software enables dynamic design in three-dimensional space. This dynamic modelling makes it possible to display and model different states simultaneously. The resultant highly complex geometries were turned into reality with the aid of innovative production technologies (rapid prototyping). The world-beating aerodynamics were developed in parallel with the aid of so-called numeric flow simulation. The aerodynamics experts from Mercedes-Benz have calculated some 300 variants.
