Reducing fuel consumption
Saving fuel
General information
Your vehicle contains advanced technology for the reduction of fuel consumption and emissions.
Fuel consumption depends on a number of different factors.
The implementation of certain measures, driving style and regular maintenance can have an influence on fuel consumption and on the environmental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts following use
Remove auxiliary mirrors, roof or rear luggage racks which are no longer required following use.
Attached parts on the vehicle impair the aerodynamics and increase the fuel consumption.
Close the windows and glass sunroof
Driving with the glass sunroof and windows open results in increased air resistance and thereby reduces the range.
Tires
General information
Tires can affect fuel consumption values in various ways, for instance fuel consumption can be influenced by the size of the tires.
Check the tire inflation pressure regularly
Check and, if necessary, correct the tire inflation pressure at least twice a month and before starting on a long trip.
Low tire inflation pressure increases rolling resistance and thus raises fuel consumption and tire wear.
Drive away immediately
Do not wait for the engine to warm-up while the vehicle remains stationary. Start driving right away, but at moderate engine speeds.
This is the fastest way for the cold engine to reach its operating temperature.
Look well ahead when driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehicle driving ahead of you.
Driving smoothly and looking ahead reduces fuel consumption.
Avoid high engine speeds
Use 1st gear to get the vehicle in motion. Beginning with 2nd gear, accelerate rapidly. When accelerating, shift up before reaching high engine speeds.
When you reach the desired speed, shift into the highest applicable gear and drive with the engine speed as low as possible and at a constant speed.
As a rule: driving at low engine speeds lowers fuel consumption and reduces wear.
Use coasting
When approaching a red light, take your foot off the accelerator and let the vehicle coast to a halt.
On a downhill gradient, take your foot off the accelerator and let the vehicle roll.
The flow of fuel is interrupted while coasting.
Switch off the engine during longer stops
Switch off the engine during longer stops, e.g., at traffic lights, railroad crossings or in traffic congestion.
Auto Start/Stop function
The Auto Start/Stop function of your vehicle automatically switches off the engine during a stop.
If the engine is switched off and then restarted rather than leaving the engine running constantly, fuel consumption and emissions are reduced. Savings can begin within a few seconds of switching off the engine.
In addition, fuel consumption is also determined by other factors, such as driving style, road conditions, maintenance or environmental factors.
Switch off any functions that are not currently needed
Functions such as seat heating and the rear window defroster require a lot of energy and reduce the range, especially in city and stop-and-go traffic.
Therefore, switch off these functions if they are not actually needed.
Have maintenance carried out
Have vehicles maintained regularly to achieve optimal vehicle economy and operating life. The maintenance should be carried out by your service center.
Also note the BMW Maintenance System.
