Schlörwagen
The ''Schlörwagen'' (nicknamed "Göttingen Egg" or "Pillbug") was a prototype aerodynamic rear-engine passenger vehicle developed by Karl Schlör (1911–1997) and presented to the public at the 1939 Berlin Auto Show. It never went into production, and the sole prototype has not survived. Design history Schlör, an engineer for Krauss Maffei of Munich, proposed an ultra-low drag coefficient body as early as 1936. Under Schlör's supervision at the AVA (an Aerodynamic testing institute in Göttingen) a model was built. Subsequent wind tunnel tests yielded an extraordinarily low drag coefficient of 0.113. For a functioning model, a Mercedes-Benz 170H chassis, one of their few rear-engine designs, was used. The aluminum body was built by the Ludewig Brothers of Essen. Subsequent tests of the motorized model showed a slightly higher but still impressive drag coefficient of 0.186. The Schlörwagen was built on a modified chassis of the Mercedes 170 H. The wheelbase was 2.60 met ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dymaxion Car
The streamlined Dymaxion car was designed by American inventor Buckminster Fuller during the Great Depression and featured prominently at Chicago's 1933/1934 World's Fair. Fuller built three experimental prototypes with naval architect Starling Burgess – using donated money as well as a family inheritance – to explore not an automobile per se, but the 'ground-taxiing phase' of a vehicle that might one day be designed to fly, land and drive – an "Omni-Medium Transport". Fuller associated the word ''Dymaxion'' with much of his work, a portmanteau of the words ''dynamic'', ''maximum'', and ''tension'', to summarize his goal to do more with less. The Dymaxion's aerodynamic bodywork was designed for increased fuel efficiency and top speed, and its platform featured a lightweight hinged chassis, rear-mounted V8 engine, front-wheel drive (a rare ''RF'' layout), and three wheels. With steering via its third wheel at the rear (capable of 90° steering lock), th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stout Scarab
The Stout Scarab is a streamlined 1930–1940s American car, designed by William Bushnell Stout and manufactured by Stout Engineering Laboratories and later by Stout Motor Car Company of Detroit, Michigan. The Stout Scarab is credited by some as the world's first production minivan, and a 1946 experimental prototype of the Scarab became the world's first car with a fiberglass bodyshell and air suspension. Background William B. Stout was a motorcar and aviation engineer and journalist. While he was president of the Society of Automotive Engineers, Stout met Buckminster Fuller at a major New York auto show and wrote an article on the Dymaxion Car for the society newsletter. Contemporary production cars commonly had a separate chassis and body with a long hood. The engine compartment and engine were located longitudinally behind the front axle, and ahead of the passenger compartment. The front-mounted engine typically drove the rear axle through a connecting drive shaft runn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aurel Persu
Aurel Persu (26 December 1890 – 5 May 1977) was a Romanian engineer and pioneer car designer, the first to place the wheels inside the body of the car as part of his attempt to reach the perfect aerodynamic shape for automobiles.Aurel Persu Romanian State Office for Inventions and Trademarks He came to the conclusion that the perfectly aerodynamic automobile must have the shape of a falling water drop, taking it one step further toward that shape than |
Rumpler Tropfenwagen
The Rumpler Tropfenwagen ("Rumpler drop car", named after its raindrop shape) was a car developed by Austrian engineer Edmund Rumpler. The Tropfenwagen Aerodynamics Rumpler, born in Vienna, was known as a designer of aircraft when at the 1921 Berlin car show he introduced the Tropfenwagen. It was to be the first ''streamlined'' production car, before the Chrysler Airflow and Tatra T77. The Rumpler had a Automobile drag coefficient, drag coefficient of only 0.28, a measurement which astonished later engineers and would be competitive even today. For comparison: the top ten most aerodynamic production cars in 2014/2015 were in the range 0.26 down to 0.19. The Fiat 508, Fiat ''Balilla'' of the mid-1930s, by contrast, was rated at 0.60. To enable the car's aerodynamic shape, the Tropfenwagen also featured the world's first (single plane) curved windows. Both the windscreen and the side windows were significantly curved. Engine The car featured a Siemens, Siemens and Halske-built over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automobile Drag Coefficient
The drag coefficient is a common measure in automotive design as it pertains to aerodynamics. Drag is a force that acts parallel to and in the same direction as the airflow. The drag coefficient of an automobile measures the way the automobile passes through the surrounding air. When automobile companies design a new vehicle they take into consideration the automobile drag coefficient in addition to the other performance characteristics. Aerodynamic drag increases with the square of speed; therefore it becomes critically important at higher speeds. Reducing the drag coefficient in an automobile improves the performance of the vehicle as it pertains to speed and fuel efficiency. There are many different ways to reduce the drag of a vehicle. A common way to measure the drag of the vehicle is through the drag area. Reducing drag The reduction of drag in road vehicles has led to increases in the top speed of the vehicle and the vehicle's fuel efficiency, as well as many other perfor ...

Mercedes-Benz 130
From 1931 to 1939, Daimler-Benz AG produced three cars (Mercedes-Benz 130, 150 and 170 H) with Rear-engine design, rear engine as well as a few prototypes. The production numbers remained quite low for each of these models, especially compared to the production of classical front-engine Mercedes cars. Development and prototypes (W17/W25D) At the beginning of the 1930s, inspired by modern streamlined shapes, there were attempts to move car engines from the forward compartment to the rear of the car. Such a move allows a reduction in the volume of the front compartment. At the same time, the voluminous rear provides a lot of space above and behind the rear axle. Moreover, when engines are rear mounted, the drive shaft is eliminated. The most famous such development was with the 1930s Tatra (car), Tatra cars under the leadership of Hans Ledwinka. In 1930, Daimler-Benz entrusted Hans Nibel with the development of a small rear-engined car, starting from the same principles. In 1931, wo ...

Hanover
Hanover (; german: Hannover ; nds, Hannober) is the capital and largest city of the German state of Lower Saxony. Its 535,932 (2021) inhabitants make it the 13th-largest city in Germany as well as the fourth-largest city in Northern Germany after Berlin, Hamburg and Bremen. Hanover's urban area comprises the towns of Garbsen, Langenhagen and Laatzen and has a population of about 791,000 (2018). The Hanover Region has approximately 1.16 million inhabitants (2019). The city lies at the confluence of the River Leine and its tributary the Ihme, in the south of the North German Plain, and is the largest city in the Hannover–Braunschweig–Göttingen–Wolfsburg Metropolitan Region. It is the fifth-largest city in the Low German dialect area after Hamburg, Dortmund, Essen and Bremen. Before it became the capital of Lower Saxony in 1946, Hannover was the capital of the Principality of Calenberg (1636–1692), the Electorate of Hanover (1692–1814), the Kingdom of Hannover ...

Concept Cars
A concept car (also known as a concept vehicle, show vehicle or prototype) is a car made to showcase new styling and/or new technology. They are often exhibited at motor shows to gauge customer reaction to new and radical designs which may or may not be mass-produced. General Motors designer Harley Earl is generally credited with inventing the concept car, and did much to popularize it through its traveling Motorama shows of the 1950s. Concept cars never go into production directly. In modern times all would have to undergo many changes before the design is finalized for the sake of practicality, safety, regulatory compliance, and cost. A " production-intent" prototype, as opposed to a concept vehicle, serves this purpose. Design Concept cars are often radical in engine or design. Some use non-traditional, exotic, or expensive materials, ranging from paper to carbon fiber to refined alloys. Others have unique layouts, such as gullwing doors, 3 or 5 (or more) wheels, or speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automobiles
A car or automobile is a motor vehicle with wheels. Most definitions of ''cars'' say that they run primarily on roads, seat one to eight people, have four wheels, and mainly transport people instead of goods. The year 1886 is regarded as the birth year of the car, when German inventor Carl Benz patented his Benz Patent-Motorwagen. Cars became widely available during the 20th century. One of the first cars affordable by the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the US, where they replaced animal-drawn carriages and carts. In Europe and other parts of the world, demand for automobiles did not increase until after World War II. The car is considered an essential part of the developed economy. Cars have controls for driving, parking, passenger comfort, and a variety of lights. Over the decades, additional features and controls have been added to vehicles, making them progressively more complex. These i ...
