BMW aims to make driving fuel-efficient with its new start-stop concept
BMW has showcased a system in collaboration with Siemens, at the American Association of State Highway and Transportation Officials (AASHTO) conference held in Palm Desert, which will communicate between the vehicle and traffic lights to optimize the engine start-stop function. In the already existing start-stop concept, the engine is turned off as soon as the car comes to halt and the clutch is released and it is started again when the clutch is pressed. Though this system is very useful in certain situations, if the time-gap between stopping and starting is only a few seconds then this system causes more than the normal amount of fuel to be burned. The new system is build to communicate the time gap between traffic signals, environment conditions, and traffic and road conditions to cars and accordingly optimize their engine usage.
This concept can give a very phenomenal increase in fuel efficiency and might as well be standard in future cars.
