BMW 7 Series and many other models now have the option to turn off the automatic engine start-stop function

News on July 29, according to "BMW Customer" reports, starting from the production month of July this year, the newly produced BMW 7 Series models will usher in a new feature. An option will be added to the center console display of these models to allow users to turn off the automatic engine start-stop function. For BMW 7 Series (G70) models that have been produced before, car owners can obtain this new feature through RSU remote software upgrade. The new function is added under the "Drive system and chassis" menu in the driving settings, specifically "Engine energy-saving start and stop settings". Users can also quickly find this option by sliding down the top menu bar or clicking on the car icon next to the gear lever. Users can choose to actively turn off this function or turn it back on, but the next time they start the vehicle, this function will be on by default.

1. Origin and purpose

Automatic start-stop technology is a technology that started in the 1970s and is designed to improve fuel efficiency and reduce emissions. When the vehicle is temporarily stopped while driving (such as waiting for a red light), the system will automatically shut down to save fuel.

2. Working principle

The automatic start-stop system relies on the following key conditions:

• The vehicle stops and the driver depresses the brake pedal
• The vehicle stops and takes off the gear
• The engine is idling and Not in gear
• The wheel speed sensor of the anti-lock system shows zero
• The electronic battery sensor shows there is enough energy for the next start

After these conditions are met, the engine will automatically stop turning.

BMW Remote Software Upgrade

After actual testing, the BMW 7 Series and BMW X5 (G18) have received the remote software upgrade option after being upgraded to the 07/2024 version through RSU remote software. The discovery has sparked speculation about whether the feature will be rolled out to more BMW models, such as the BMW 5 Series, BMW X6 and BMW X7 equipped with iD8.5 engines. -->
