Why does the aerodynamics of a commercial vehicle the same time or perhaps even a larger role than in a Car? If you look at a Truck, then everyone is visually seen rather like a wall. Especially in the transport sector, the efficiency is but one of the key factors and so the fuel consumption or fuel efficiency cost for the maintenance. In a current Truck, spent about a third of the available mechanical energy by Burning fuel to Overcome air resistance. Every drop of Diesel in the must have less to be burned, so it is money for the freight forwarding company.

The wind tunnel at the Untertürkheim plant

A Truck like the Actros as efficiently as possible so to make, will worked extensively on the aerodynamics of the Trucks. The development is done virtually on the computer, but also real experiments in the wind tunnel. At the plant in Untertürkheim, Daimler AG has a wind tunnel. Already since 80 years in operation, and thus the oldest of the 1-to-1 wind tunnel in Europe. Thanks to targeted modernization, he is still on the current state of the art.

Optimized aerodynamics of the new Actros ensures fuel efficiency

Nine-wing axial fan ensures the strength of the wind 17

The heart of the installation is a nine-wing axial fan with 8.5 meters in diameter. Each of the wings brings it to a weight of 850 kilograms. Powered by the wings of two DC motors, each with 2500 kW of power put to the fan so vigorous in movement, that even the wind can be given to strength of 17. In order for Tests can be up to a wind speed of 250 km/h on the plant.

Test range with a turntable

In the test area of the test Vehicle is on a turntable with twelve meters in diameter, so that it can be exposed to the wind stream at the front or at any other desired angle to the side. In the hub of a Six-component balance is integrated. It serves for the highly accurate determination of many forces, including the air force. The forces are transmitted through levers and rods to the load cells and thus can be evaluated made.

Tests in the wind tunnel for the new Actros with MirrorCam

The current Generation of the Actros has for the first Time about a MirrorCam instead of the classic outside mirror. The associated improved aerodynamics contributes up to 1.5 percent to the total saving in fuel consumption of the new Actros. Possible this was due to the intensive work in the wind tunnel. In the experiments simulated, the engineers, the flow conditions on the Truck, with the aim to determine the best Position for the camera arms of the MirrorCam. To the debate of the upper and the lower area of the A-pillar and the upper portion of the B-pillar stood.

Optimized aerodynamics of the new Actros ensures fuel efficiency

For the Experiments a real Actros was used, which had replaced the exterior mirrors by means of prototypes of the camera arms – sequentially applied to test the three positions. The Truck was placed on the scale of the wind tunnel and the fan is set in motion. The scale allowed the engineers to measure the air force, which influenced the flow around the vehicle. Result: The best Position for the camera arms located on the A-pillar in the area of the edge of the roof.

Development for more fuel efficiency

The wind tunnel were also used for the development of the new concave-shaped trailing edge flaps on the cab. The new Dampers also contribute to that as little fuel is required to as possible. All of the aerodynamic improvements, together with the optimized cruise control and control Predictive Powertrain Control (PPC), as well as the new final drive ratio in the transmission, finally, the new Actros on highways up to three per cent, and in intercity traffic for up to five percent less fuel than its predecessor. Alone the MirrorCam contributes around 1.5% to the total fuel savings, what is the fuel efficiency contributes.

Sacrifice at Mercedes-Benz the Mercedes-Benz S-class Coupé and the convertible of the current series 217 for the upcoming EQ model ? The good candidate on the string bar of the Ola Källenius, of which is highly likely – and also the coupe and the Cabriolet, the S-class is a Post about it. Confirmations are yet to come.

S-class coupe & convertible to make space for the EQ ? Production will end in August 2020

S-class Cabriolet and coupe will not be replaced

With the S-class Cabriolet and Coupé, it will probably go faster than I thought: after first rumors in the setting of series 217, we expect the current with a fast setting of the model variant – in the year 2020. We expect that it is possible to order the two upper-class variants, probably only up to approx. beginning of may 2020 and the production could then be phased out of the factory holiday in August.

S-class coupe & convertible to make space for the EQ ?

Open-top driving comfort in the top class of the series 217

With a setting of the series, we completed, among others, the open-top driving comfort in a S-class, which you can currently enjoy from 144.644,50 Euro. The closed coupe is in the basic equipment from 102.756,50 Euro can be ordered. Both variants of the model have been to the IAA in 2017 in the revised Version of the model of care presented.

A direct successor for the series 217 is that it is the on the other hand, apart from the electrified EQS model from Mercedes-Benz. Here is the model in Sindelfingen space for the production of the new EQ model.

What is the rear-view mirror, windshield wipers and hood ornament have in common? There are three of “33 Extras” that draw in the permanent exhibition at the Mercedes-Benz Museum and view fascinating Details of the mobility history and automotive culture to life are. And one more thing in Common, they have: The story of the three exhibits, each inspired by women, as the hat for women.

5/33: The Ladies ‘ Hat

Women in elegant Outfits in the early 20th century. Century to enforce as drivers, is an important piece of women’s emancipation in everyday life. This movement Bertha Benz leads. You actively, to the great invention of her husband, Carl Benz is showing the way. The Patent motor car she drives from the first day, and among the first in the summer of 1888 long-distance journey with an automobile. On the open tricycle, she protects against Wind and weather. Contemporary depictions show her with a wide-brimmed hat, the scarf holds.

The speeds will grow, and the cantilevered head covering reached their limits: The wind catches and pulls strong to the wide-brimmed Hats. But the woman knows how elegant and help at the same time of style: the 1920s and 1930s, the tight-fitting hat to Topfhut called. Like combined with a bobbed-hairstyle – the modern woman underlines your self-confident appearance. This is the story of the ladies ‘ hat is told in the exhibit is number “33 Extras” of the Mercedes-Benz Museum.

And who delivers the practical and at the same time, fashionable headgear for the perfect appearance? There is a own career for the Making of ladies ‘ hats: the milliner. Previously, she was a milliner, because the hat belongs to “plaster” – the lady dressed in order. Buying the hat is not easy, but can be detailed to advise the design and Details, and most of the time he is made not specially.

Then, as the cars and closed bodies, lose the hat its functional importance. Today, hats are to be worn in everyday life rather rare. But there are occasions when gentlemen as well as ladies show up with stylish head covering – for example, in the case of events of the automotive classic. Here, you can stroll around the fine lawn of a Concours d’elegance, between noble automotive, it must be for you like the wide-brimmed hat. And in the case of an exit of the tight-fitting option. Like I used to.

Due to the current COVID-19 pandemic is probably to be expected with shifts of dates of all the upcoming Changes in April and may, what all the first of the compact models, as well as the revised E-class should meet.

Not only are compact models affected

The towards the end of April 2020, the expected dates for the change of the year 20/1 in the compact models, you will – in all likelihood – due to the current Situation can’t hold. The hits, the models of the A-class sedan (V 177), B-class (W 247), as well as the CLA coupe CLA Shooting Brake (C/X 118), what are we to 23. April 2020 had expected. Thus, inter alia, the B 250 e series 247, as well as the CLA 250 e well not in April 2020 can be ordered.

The change of the year 20/1 for the S-class Cabriolet and Coupé (A/C-217) in April 2020, is also still questionable.

Postponements for April and may

In mid-may the approval for the change of the year 20/1 of the E-class sedan, T-model, as well as parallel also as a coupe and Cabriolet was to be expected, what concerns here at the same time, approval for the model of care. Here, too, we expect a shift in time according to the back. Similarly, the change of the year 20/1 for the CLS Coupé (C 257) is moved to the well-being of Mercedes-Benz.

Currently ignored by the market launch for the E-class sedan and T-model in the series 213 in 3 should. Quarter, as well as for the Cabriolet and coupe in the 4. Quarter of the current year be secured.

GLE series is probably just as affected.

At the beginning of may, we had planned the change of the year 20/1 for the GLE and the GLE coupe, as well as the GLS series 167, which could move as well. The hits may be the planned market launch of the GLE coupe within the 2. Quarter of 2020. Similarly, the G should be affected here-class (W 463), as well as the AMG GT to be a series, we had the same with a change in the year (and then also with Changes in the engines) at the beginning of may expected.

GLC and C-class will get change year 20/1 only in July

No Changes by the way the EQC (N 293), for the currently, there is no change in the year is pending. For the GLC or the GLC coupe a change year, 20/1 is expected to be until July 2020, which is also the case for the C-class model series 205.

Confirmations, postponements are not available, by the way, due to the production and mostly the government shutdown, we anticipate strong so that you can a variety of scheduled and planned appointments for April and may as well no longer hold.

In terms of the spread of the Coronavirus in the auto group Daimler is now also the U.S. operation to a large extent. In the US plant in Tuscaloosa, Alabama as well as in the Van-production in Charleston (South Carolina) are stopped, the belts of the production, initially for 14 days temporarily.

The Mercedes-Benz plant in Tuscaloosa (Mercedes-Benz U.S. International – MBUSI) in Alabama is a production site for the latest SUV model series GLE, GLE coupe and GLS. Furthermore, the C produced-class sedan for the North American market.

With the stop of the production in Alabama and in South Carolina, Daimler follows the recommendations of the national, international as well as local authorities. In the related administrative departments of the company in the operation is to be limited parallel to the bare minimum.

Already at the beginning of the week it was announced that Daimler AG is suspending most of its production of passenger Cars, vans and commercial vehicles in Europe due to the COVID-19 pandemic.

With the now confirmed settings of the US-production, Daimler follows already from other manufacturers. In addition to General Motors (GM), Ford, Fiat Chrysler, just as Volkswagen has ceased production until the end of the month.

Fascinating sports car icon and media darling, a rolling laboratory for the development of the Wankel rotary engine, as well as for testing new technologies and, not least, the car’s legendary record of This and much more is the Mercedes-Benz C 111. Its second stage of development of the C 111-II with the 257 kW (350 HP) Four-disc version of the rotary-piston engine M 950 F (four times 602 cubic centimeter of chamber volume) this year celebrates a milestone birthday.

1970: Premiere for the C 111-II from Mercedes-Benz at the Geneva motor show

Premiere

Presented the super sports car 50 years ago at the age of 40. Geneva motor show from the 12. to 22. March 1970. The 1.120 mm flat new Gullwing with 2.620 mm wheelbase version has a body made of glass-fiber-reinforced plastic (GRP), which is bolted to the frame-floor unit made of sheet steel. Its maximum speed is up to 300 km/h. A magnet for the public he is today: A Mercedes-Benz C 111-II in the characteristic painting “white autumn” is in the Mercedes experience-Benz Museum in the exhibition area “fascination technology”.

Further development of the C 111

The C 111-II on the Basis of the in the autumn of 1969 presented the C 111. Technically, it is characterized in particular by the Four-rotor Wankel engine, a real sports motor. Design development under the guidance of Bruno Sacco, and Josef Gallitzendörfer begins in the summer of 1969. Among other things, the driver’s view is improved compared to the predecessor, with the changes in fenders, roof and rear lid. The aerodynamics were also optimized: the wind tunnel measurements compared to the C 111 eight percent reduction in air resistance. The interior of the C 111-II impresses with its modern Aesthetics. Its everyday practicality is underlined in the dream car, for example, by the fact that it offers space for one large and two small suitcases of the Mercedes-Benz suitcase set.

Dream Car of the 70s

The C 111 was from the start a Highlight. Thus, the Plan of the management Board of the former Daimler-Benz AG: This decides on the 20. In may 1969, the C 111 car as a “dream” of 11. to 21. September 1969 to be presented at the International automobile exhibition (IAA) in Frankfurt am Main. After the sensational debut of the C 111 has appeared on numerous other fairs and exhibitions: the Automobil-Salon in Paris, the London Motor Show (October 1969), the Turin Salon (October / November 1969), the Jochen Rindt Show in Vienna (November 1969) and Essen (December 1969), the auto Salon in Brussels (January 1970) and the Chicago Auto Show (February 1970). In Geneva, the further-developed Version of the C 111-II to Premiere in March 1970.

Blank checks up to half a Million DM

Cash-rich sports car fans are willing to pay high sums of money for a C 111. Already in London in 1969, a car which offers mobile lovers up to half a Million DM. In the following months of blank checks to meet even in Stuttgart. However, the brand stresses that the experimental vehicle is not for sale. At the very beginning of his career, the later C 111 (the Mercedes-Benz under the internal designation C 101 carries), but for a completely different target group, determines: in 1963, you think about a Wankel engine in a “small, inexpensive sports car” to be placed below the “pagoda”SL (W 113). At the end of 1968, this orientation is concretized in the “small sporty car” without a distinct comfort, the is also suitable for rally racing, and “younger people” appeal.

Driving experience in Geneva

In Geneva, the C 111-II is experience 50 years ago, not only as an exhibition Highlight, but also in travel. Because of the second series, Mercedes-Benz brings two of the five planned experimental vehicles using the automobile salon. The attempt with the internal number 31 in the first C 111-II, and in the framework of the press screening on 10 cars. and 11. To experience March 1970 at the Circuit de Monthoux, Geneva for demonstration rides.

Already digital on the Computer

The C 111 not only has his Form in the future. He is also the world’s first automobile to be designed from scratch on the Computer. The engineers use the procedure ESEM (elasto-statics-Element-method), a Mercedes-Benz has developed a variant of the Finite element method (FEM). The digital technology allows even the calculation of dynamic loads. At Mercedes-Benz it is estimated that around four months of development time can be saved. The in-house documentary film, “The car that came out of the Computer” introduces the Innovation.

V8 instead of a rotary

In December 1970 is to be installed in a C 111-II in place of the Wankel rotary engine, a Mercedes-Benz 3.5-Liter V8 reciprocating engine. This vehicle from Mercedes-Benz Classic makes the C 111 today also dynamic, experienced, and mobile classic provides for events of the car again and again for enthusiasm. A different individual piece of the company’s vehicle collection is a C 111-II from the year 1975: the floor-to-group consists of a Sandwich of two only a few millimeters thick, glass-fiber reinforced resin shells, which are welded with a polyurethane foam core composite waste.

Butter and Ski

The C 111-II compared to its predecessor, some of the comfortable Details. In particular, Rudolf is Uhlenhaut, head of Mercedes-Benz passenger car development. In addition to the regular trunk, for example, the placement of a piece of baggage belts on the rear lid with clamping, as well as the skitrans port provided. Uhlenhaut is the C 111-II, a practical “Butter test” to undergo: It is tested during a sporting journey, whether a packet of Butter in the trunk – melts, in spite of its insulation against the heat of the combustion drive.

Take a stand: “white autumn” painting

Today, the C 111-II is like its predecessor in the public consciousness, of course, is the orange metallic color “white-connected to autumn”. First of all, the end of the 1960s, however, it is a painting in the “vermilion” and decorated with a racing stripe idea. 1969: the C 111 first appears in a white special-effect paint, and in fluorescent orange. Up to the Premiere of the C 111-II in Geneva, 50 years ago, the painting “but the fall of white” as the typical color.

Record-breaking car

The development of the Wankel-engine super sports car will continue to run after the C 111-II, and its counterpart with plastic bottom group at Mercedes-Benz. However, the star of the experimental vehicles emits more light. Because it is the Basis of the highly successful record vehicles C 111-II D (1976), the C 111-III (1977) and the C 111-IV (1979) arise.
