Ultralight material also has elastic properties. Some ultralight materials are designed with more pores to allow the structure to have better heat transfer, which is needed for many materials, like pipes for example. [3] [1] In compression experiments, ultralight materials almost always show complete recovery from strains exceeding 50%.
For the first time Karl Benz publicly drove the car on July 3, 1886, in Mannheim at a top speed of 16 km/h (10 mph). [10] Benz later made more models of the Motorwagen: model number 2 had 1.1 kW (1.5 hp) engine, and model number 3 had 1.5 kW (2 hp) engine, allowing the vehicle to reach a maximum speed of approximately 16 km/h (10 mph).
Today, this is known as "the first Marcus car" but would be better described as a cart. His second car, built and run in 1875 according to some sources, was the first gasoline-driven car and is housed at the Vienna Technical Museum. [30] [31] However, the latest research shows that it was not built until 1888/89. [32]
From 1894 to 1902, Benz produced over 1,200 of what some consider the first mass-produced car, the Velocipede, later known as the Benz Velo. [20] The early Velo had a 1L 1.5-metric-horsepower (1.5 hp; 1.1 kW) engine, and later a 3-metric-horsepower (3 hp; 2 kW) engine. giving a top speed of 19 km/h (12 mph).
The Trabant 601 car body is made of Duroplast [1] Duroplast is a composite thermosetting resin plastic developed by engineer Wolfgang Barthel in 1953 [ 2 ] in the German Democratic Republic . [ 3 ] [ 4 ] Its production method places it in a similar family as Formica and Bakelite .
Elwood Haynes (October 14, 1857 – April 13, 1925) was an American inventor, metallurgist, automotive pioneer, entrepreneur and industrialist.He invented the metal alloy stellite and independently co-discovered martensitic stainless steel along with Englishman Harry Brearley in 1912 and designed one of the earliest automobiles made in the United States.

Lambert Lambert 1901 experimental automobile John Lambert and his brothers in 1902 in a Union Automobile Lambert 1907 automobile advertisement with the friction transmission featured in it. Lambert Automobile Company, 1908. Lambert had more than 600 inventions. [3] [4] [5]
One material sometimes used to reduce weight for structures that can accept the cost premium is carbon fiber. [9] The auto industry has used the term for many years, as the effort to keep making cars lighter is ongoing. [2] Another common material used for lightweighting is aluminum. [10]
