Driving Techniques for Optimal Energy Use

Understanding your van’s energy data is only half the battle. The other, crucial half is implementing driving techniques that leverage this knowledge for maximum efficiency. This is where you, the driver, have immense power to impact your Citan’s performance and your wallet.

Smooth Acceleration and Braking

Abrupt acceleration and hard braking are energy killers. They require more fuel to accelerate quickly and generate excess heat (wasted energy) during braking.

Gentle Acceleration: Gradually increase your speed. Imagine you have an egg under your accelerator pedal.
Anticipate Traffic: Look ahead and anticipate traffic lights, stops, and other vehicles. Smoothly lift off the accelerator to coast rather than braking hard at the last moment.
Utilize Engine Braking: On downgrades, letting the vehicle’s speed control the engine (without pressing the accelerator) uses no fuel and also helps to conserve your brakes.

Maintaining Consistent Speed

Fluctuating speeds burn more fuel than maintaining a steady pace. Your Citan’s engine and transmission are most efficient within a particular operating range.

Use Cruise Control: On highways and long, open stretches, cruise control helps maintain a consistent speed, optimizing fuel consumption.
Avoid Unnecessary Speeding: Fuel consumption increases significantly at higher speeds due to increased aerodynamic drag. A few miles per hour less can save substantial fuel over time.

Reducing Electrical Load

Every electrical accessory draws power, which ultimately comes from the engine’s energy output (fuel).

Manage Air Conditioning: AC compressors consume a noticeable amount of power. Use it judiciously. On cooler days, opening windows can be a more energy-efficient way to ventilate.
Turn Off Unnecessary Electronics: If you’re not using the radio, extra lights, or other powered accessories, turn them off.
Be Mindful of Idling: While your Citan is designed to manage its electrical systems, excessive idling still burns fuel without covering distance. Turn off the engine for prolonged stops if practical and safe.

Proper Tire Maintenance

Underinflated tires increase rolling resistance, meaning your engine has to work harder to move the vehicle, consuming more energy.

Check Tire Pressures Regularly: Aim for at least once a month, and always before long trips.
Use Recommended Pressures: Find the correct tire pressures in your owner’s manual or on the sticker located on the driver’s doorjamb. Do not use the maximum pressure listed on the tire sidewall.

According to the U.S. Department of Energy, proper tire inflation can improve gas mileage by up to 3%.

Essential Maintenance for Energy Efficiency

Beyond driving style, regular maintenance is paramount for ensuring your Citan van operates at peak energy efficiency. Neglecting simple tasks can lead to increased fuel consumption and premature wear on vital components.
