In 1967, a concept car was presented by BMW and Bayer at the plastics trade fair in Düsseldorf.
At the Tokyo Motor Show in 2019, Toyota presented a new electric concept car: the Toyota LQ. A highlight of the LQ is the use of artificial intelligence to create an emotional connection between the vehicle and the driver. This should be achieved in particular by adapting the interior lighting, scenting or seat air-conditioning to the driver's needs. In addition, the LQ is equipped with automated driving functions.
