Mercedes-Benz IAA Concept PREVIEW
NetCarShow


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 Frankfurt International Motor Show, 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, 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 Prof. Dr Thomas Weber, Member of the Daimler Board of Management responsible for Group Research and Head of Mercedes-Benz Cars Development.

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 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 numeric flow simulation. In around one million CPU hours, the aerodynamics experts from Mercedes-Benz simulated the flow characteristics, calculating some 300 variants. This roughly corresponds to the scope of work involved in developing a production model.

The "Concept IAA" also offers a look into the future in areas which are not apparent at first glance. The study features Car-to-X technology, for example, which enables the study to communicate with other vehicles or other sources of information. This represents a major advance in helping to avoid accidents, as obstacles or events which are not visible to the vehicle itself can be detected - the "Concept IAA" is able to look around the corner, as it were. With this and its interior and operating concept, the "Concept IAA" also offers a foretaste of the business saloon of the near future.

Exterior design: sensual purity and innovative aerodynamics...

The interior: touch-based operating philosophy...

...The "Concept IAA" is 5040 millimetres 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). CO2 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 kilometres and emits 28 g CO2 per km. In design mode the range stands at 62 km and CO2 emissions at 31 g per km. As urban driving is accorded a two-thirds weighting in the current New European Driving Cycle (NEDC), the advantage of aerodynamic mode is not revealed as clearly in this test as in real-life driving...

New Cd world record achieved through active transformation
Two cars in one - on reaching a speed of 80 km/h, the "Concept IAA" switches automatically from design mode to aerodynamic mode, whereupon numerous active aerodynamic measures alter its appearance. As a result of this transformation, the Cd value improves from 0.25 to 0.19 - a new world record for a four-door four-seater. The frontal area totals 2.16 m2.

The active aerodynamic measures at a glance:
• The front flaps in the front bumper in front of the wheel arches move outwards by 25 millimetres and 20 millimetres to the rear, up to the rear edge of the wheel crescent. This substantially improves the inflow of air to the wheels and the flow of air over the front wheel arches.
• The louvre in the front bumper moves 60 millimetres to the rear, improving the flow of air towards the underbody.
• The Active Rims alter their cupping with the aid of centrifugal force from 55 to 0 millimetres, transforming them from sporty 5-spoke wheels into flat disc wheels offering exemplary aerodynamic characteristics.
• In conjunction with the diffuser, the rear extension which is extendable by up to 390 millimetres ensures that the air flow hugs the vehicle more closely and that the after-flow zone behind the vehicle's rear end is substantially smaller. This results in a considerable reduction in drag. The rear extension in "boat tail" design consists of eight segments produced in CFRP in a sandwich structure which close to form a ring...

Lots & LOTS More..........

They seem to have a very distinct look for their electric/Tesla competitor. But the theme at this show is definitely Tesla.

This is why I don't think Tesla can survive, there is just no way they can iterate and keep up with bigger luxury manufacturers.

I agree with you. Can Tesla beat Porsche (with the VW giant behind it), BMW and Mercedes-Benz ? I doubt it.

Mercedes-Benz Has A Concept Car That Grows By Nearly 16 Inches
TTAC

By Aaron Cole on September 15, 2015

While it may or may not be the next-generation Mercedes-Benz CLS-class (note: probably not), the automaker took the wraps off a transforming concept car that grows in length significantly at highway speeds to better cut through air.

The Mercedes-Benz IAA concept (Intelligent Aerodynamic Automobile) was shown off Tuesday in Frankfurt and, according to the automaker, can grow by 390 millimeters to achieve a drag coefficient world record of 0.19. (The current generation Prius is around 0.25, for reference.)

The whole thing is powered by a hybrid powertrain that’ll never see the light of day and sports an interior array of electronics that’s probably something out of “Minority Report.” It’s the moveable aerodynamic elements on the IAA that could see production, and there are a lot of them.

In addition to the growing tail (Jalopnik has a gif, here) the IAA features other adaptive aero elements that help the car cut through the air. Flaps on the front and rear wheels grow by 25 millimeters and 20 millimeters respectively to cut down drag, and the front bumper’s louvres reach 60 millimeters underneath the car toward the rear to improve aero under the car. The five-spoke wheels also transform into discs at speeds over 50 mph, according to the automaker...
