Eco-Friendly Driving and Vehicle Loading Flashcards

Which driving technique most effectively reduces fuel consumption?

Answer: Driving in the highest appropriate gear at a steady speed

Driving in the highest suitable gear at a smooth, steady speed minimises fuel consumption and engine wear.

How does an incorrectly inflated tyre affect fuel consumption?

Answer: Under-inflated tyres increase rolling resistance and raise fuel consumption

Under-inflated tyres have a larger contact patch and higher rolling resistance, forcing the engine to work harder and burn more fuel.

What effect does carrying unnecessary weight in your vehicle have?

Answer: It increases fuel consumption and tyre wear

Every extra kilogram the engine must move requires more fuel, so removing unnecessary items from the boot reduces running costs.

A roof rack with no load fitted to your vehicle will:

Answer: Increase fuel consumption due to extra aerodynamic drag

Even an empty roof rack creates additional aerodynamic drag, which forces the engine to work harder and increases fuel consumption.

At what engine action do vehicles typically use the most fuel?

Answer: Idling at traffic lights for extended periods and heavy acceleration

Excessive idling and harsh acceleration both burn disproportionately large amounts of fuel compared to smooth, progressive driving.

What is the most eco-friendly action to take when you know you will be stationary for more than a couple of minutes?

Answer: Turn the engine off

Switching the engine off when stationary for more than a minute or two prevents unnecessary fuel burn and reduces exhaust emissions.
