2023 BMW M5 Owners Manual - Saving fuel



Saving fuel

Reducing fuel consumption

General information

The vehicle contains advanced technologies for the reduction of consumption and emission values.

The fuel consumption depends on various factors, such as driving style, road conditions, maintenance or environmental factors.

Carrying out certain measures, such as a moderate driving style and regular maintenance, can influence fuel consumption and the environmental pollution.

Removing unnecessary cargo

Additional weight increases fuel consumption.

Removing attached parts following use

Remove roof-mounted luggage racks that are no longer required following use.

Attached parts on the vehicle impair the aerodynamics and increase the fuel consumption.

Closing the windows

Open windows increase drag and therefore lead to greater fuel consumption.

Tires

General information

Tires can affect consumption in various ways, for instance tire size may influence consumption.

Checking the tire pressure regularly

Check and, if needed, correct the tire inflation pressure at least twice a month and before starting on a long trip.

Low tire pressure increases rolling resistance and thus fuel consumption and tire wear.

Additional information:

Tire pressure specifications.

Drive away without delay

Do not wait for the engine to warm-up while the vehicle remains stationary. Start driving right away, but at moderate RPM.

This is the fastest way of warming the cold engine up to operating temperature.

Anticipatory driving

A smooth and anticipatory driving style reduces fuel consumption.

Avoid unnecessary acceleration and braking.

Maintain a suitable distance to the vehicle driving ahead of you.

Avoid high RPM

Driving at low engine speeds lowers fuel consumption and reduces wear.

If necessary, observe the vehicle's gear shift indicator.

Using coasting/overrun mode

When approaching a red traffic light, take your foot off the accelerator and let the vehicle coast to a halt.

For going downhill take your foot off the accelerator and let the vehicle roll.

The fuel supply is interrupted in coasting/overrun mode.

Switch off the engine during longer stops

Switching off the engine

Switch off the engine during longer stops, for instance at traffic lights, railroad crossings or in traffic jam.

Auto Start/Stop function

The Auto Start/Stop function of the 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 an engine stop.

Switching off any functions that are not currently needed

Functions such as seat heating and the rear window defroster require a lot of energy and increase fuel consumption, especially in city traffic and with stop-and-go driving.

Switch off these functions if they are not needed.

Having maintenance carried out

Have the vehicle maintained regularly to achieve optimal vehicle efficiency and service life. BMW recommends that maintenance work be performed by a BMW service center.
