FRANKFURT: The Mercedes-Benz “Concept IAA” (Intelligent Aerodynamic Automobile) is two cars in one: an aerodynamics world champion with a C
d
value of 0.19 and a four-door coupé embodying irresistible design.
The study, which is celebrating its world premiere at the Frankfurt International Motor Show, switches automatically from design mode to aerodynamic mode when the vehicle reaches a speed of 80 kph, 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, offers new touch-based functions and provides an idea of what the interior of a business saloon might look like in the near future.
At the touch of a button, or automatically on reaching a speed of 80 km/h, the Mercedes-Benz “Concept IAA” (Intelligent Aerodynamic Automobile) 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 mm to the front and 20 mm to the rear, improving the air flow around the front end and the front wheel arches; the Active Rims alter their cupping from 55 mm to zero; and the louvre in the front bumper moves 60 mm to the rear, improving the underbody air flow.
“Fascinating and technically sophisticated cars form the core of Mercedes-Benz. 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 member of the Daimler Board of Management for Group Research and Head of Mercedes-Benz Cars Development, Prof. Dr Thomas Weber.
Equally, the “Concept IAA” exemplifies the fundamental technological changes which are taking place in the automobile industry. The primary driving force behind this process of change is digitisation – commonly referred to in a business context as “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 interior of the “Concept IAA” combines stylish sportiness with modern luxury. The interior continues the design line of the S-Class and S-Class Coupé while providing an idea of what the interior of a business saloon might look like in the near future. The choice of colours and materials conjures up extrovert contrasts between anthracite and white as well as between aluminium and cut glass. Elegantly curved forms, flowing lines, carefully chosen high-quality materials and the touch-based operating philosophy provide for a high level of functionality.
The steering wheel also incorporates touch-based operating functions, offering great functionality in the most compact dimensions as a study in perfect ergonomics: OFN (Optical Finger Navigation) buttons, embedded in the clusters in a similar hovering manner as the touchpad in the centre console, enable the driver to scroll through the instrument cluster menus.
The OFN button on the left controls the left-hand display, while the button on the right controls the right-hand display. In this way, the “hands on the wheel, eyes on the road” operating philosophy which has been applied by Mercedes-Benz for many years now is implemented in a manner which is at once brilliantly simple and uncompromising.
The “Concept IAA” is 5040 mm long (5430 mm in aerodynamic mode), 1995 mm wide and 1305 mm high. Its wheelbase measures 2975 mm, and the front/rear track widths are 1710 and 1770 mm respectively. The concept car is powered by a petrol/electric plug-in hybrid drive with a total output of 205 kW (279 hp). This provides it with a top speed of 250 km/h (electronically limited). CO

emissions and electric range depend on the mode in which the vehicle is tested: in aerodynamic mode the “Concept IAA” manages an all-electric range of 66 km and emits 28 g CO

per km.
The “Concept IAA” show car forms part of a long line of aerodynamically perfected vehicles from Mercedes-Benz. With a dimensional concept that makes it suitable for everyday use, this four-seater attains a C
d
value of 0.19, assuring it of a place in the gallery of record-breaking and racing vehicles such as the Mercedes-Benz W 25 record-breaker of the 1936 season.
