BMW 1-Series features ‘stop-start’ system

The latest petrol and diesel versions of the BMW 1-Series feature a system designed to reduce fuel consumption and cut carbon dioxide emissions.

Created by Bosch, the ‘stop-start’ technology will cut out the car’s engine when the vehicle is waiting in traffic or has stopped at lights. It will immediately reignite when the clutch pedal is depressed, prior to the car moving off.

According to the component supplier, the system will provide a cost-effective way of conserving resources and also protect the environment.

"This technology reduces fuel consumption significantly, especially in city centre driving," said Dr Volkmar Denner, a member of the Bosch board of management.

"This and other systems supplied by Bosch will help to reduce CO2 emissions further in the future."

European guidelines currently suggest that a dozen 15-second stops should be made over a distance of seven kilometres.

According to Bosch, the stop-start system can reduce fuel consumption and CO2 emissions by up to eight per cent over such a journey. When stops last longer, in bad traffic jams for instance, the fuel and emissions savings can be significantly higher.
