Gear shift indicator.

Changing gear at the correct time can save fuel. The gear shift indicator, from BMW EfficientDynamics, displays the most efficient gear to use in every driving situation.

All BMW 3 Series Convertibles with a manual transmission come with the gear shift indicator: it constantly calculates which gear is currently the most economical and accordingly advises the driver when to shift. When calculating, the system takes both the driving situation and engine load into account. Changing gear at the right moment can considerably reduce fuel consumption.
