There is a car engineering strategy, known as “lightweighting”, aimed at developing lightweight structure cars to improve fuel efficiency, dynamics and driving. The lighter the car, the faster it accelerates, the more maneuverable and efficient it is. Using lightweight materials in car building leads to less strain on the engines, reduced fuel consumption and better car handling.
BMW knows that and strives for lightweighting to achieve better performance for its electric cars. To reduce car weight, the German carmaker uses innovative material at car building – the carbon fiber.
The carbon fiber (Carbon fiber reinforced polymer/CFRP, carbon fiber reinforced plastic or carbon fiber reinforced thermoplastic/CFRTP) is a light and highly resilient composite containing the carbon fibres and the matrix of plastic. It is 50% lighter than the steel and 30% lighter than the aluminum, but it is extremely strong and safe for being used in the industries requiring high strength-to-weight ratio and rigidity – aerospace, civil engineering, and, of course, car engineering industry.
