Fuel consumption optimization is the most direct and impactful cost-reduction lever for a fleet manager.

With fuel accounting for up to 30% of the Total Cost of Ownership (TCO), every liter saved translates into increased profitability.

An effective optimization strategy combines technology, processes, and training.

The most effective methods revolve around three major axes: 1.

**Driving Behavior: Eco-Driving** This is the most influential factor.

Telematics technologies allow for its objective measurement by identifying energy-intensive habits: harsh acceleration, sudden braking, excessive speed, and prolonged idling.

By training drivers and implementing a scoring and coaching system, companies see consumption reductions of 5% to 15%.

Eco-driving also reduces vehicle wear and tear and accident risk.

2.

**Route and Mission Optimization** Fewer kilometers driven mathematically means less fuel consumed.

Route optimization software no longer just shows the shortest path.

It calculates the most efficient route by integrating real-time traffic, time constraints, and avoiding unnecessary detours.

Furthermore, good planning helps avoid 'empty miles' and maximizes payload, thereby improving the efficiency of each trip.

3.

**Preventive Maintenance and Vehicle Condition** A poorly maintained vehicle consumes more fuel.

Several points are crucial: - **Tire pressure:** Under-inflated tires can increase fuel consumption by 2% to 4%.

- **Engine maintenance:** Regular replacement of filters (air, oil, fuel) and the use of quality engine oil ensure optimal engine performance.

- **Unnecessary weight:** Unneeded materials or equipment add weight to the vehicle and increase its consumption.

By combining these three approaches and relying on precise data provided by fleet management software, a company can achieve substantial and sustainable fuel cost reductions.
