Does smooth driving save fuel?

In general, yes. Aggressive driving usually uses more fuel than smooth driving.

Why it helps

Accelerating hard burns more fuel, and braking hard throws away the speed you just paid for. If you anticipate traffic and let the car slow gradually, you reuse momentum instead of wasting it.

Other things that matter

• Speed: fuel use tends to rise at higher highway speeds.
• Tyre pressure: under-inflated tyres increase resistance.
• Weight and roof racks: extra load and drag cost fuel.
• Short trips: cold engines are less efficient.

Be realistic

The size of the saving depends on your car, roads and traffic, so treat any exact percentage with caution. The habit is still worth building, because it is also calmer and gentler on brakes and tyres.

Track your own trips

Road Rank lets you add your vehicle and see an estimated fuel cost per drive, so you can compare calm trips with rushed ones.
