Plan before chasing a number
Economical driving reduces unnecessary acceleration, braking and journeys, rather than pursuing a dashboard figure at any cost.
Plan the route, traffic delays and fuel or charge. Combining trips or using suitable alternative transport can reduce consumption too. Do not expect a fixed saving percentage: the vehicle, weather and route matter.
Look ahead and keep a margin
- Read traffic, signals and crossings early.
- Following distance gives you time to slow smoothly when traffic ahead is already braking instead of accelerating again.
- Do not crawl unnecessarily or obstruct traffic for economy.
- Safe speed depends on visibility, grip and other road users as well as the posted limit.
Choose a suitable gear
In a manual, use a gear that keeps the engine running smoothly with enough pulling power.
There is no universal compulsory second-to-fourth shift: skipping gears must suit speed, load and conditions. In an automatic, use the intended modes and manufacturer guidance. Do not switch the engine off or select neutral to coast on the road.
Deceleration and regeneration
Lifting off early can help, but it does not replace the service brake when needed.
Combustion cars, hybrids and EVs decelerate differently; regeneration can change with a cold or charged battery. Do not assume identical slowing every time. “Engine braking always uses zero fuel” is not a valid universal promise.
Condition and unnecessary load
- Maintain tyre pressure according to the manufacturer for the load, not above it to chase savings.
- Remove unneeded luggage and unused external carriers where the design permits.
- Economy measures must not compromise visibility, grip or load security.
- Servicing can investigate unusual consumption, but one high reading does not establish a fault.
Idling and the driving test
Avoid unnecessary engine running with regard to the vehicle and situation.
Section 16’s rule about needless idling noise and emissions concerns built-up areas or their vicinity; it is not an instruction to stop the engine for every momentary halt. The test considers independent, safe interaction overall. Do not sacrifice necessary braking, observation or a confident safe entry for an “eco” gesture.
