Smarter driving

By making small improvements to the way you drive, you can reduce your environmental impact and cut fuel costs by as much as 10%. Follow these simple steps to make your journey more energy efficient:

Maintain - Well maintained vehicles tend to run more efficiently.
Keep the pressure up - Check regularly to make sure your tyres are inflated to the correct pressure for the vehicle - under-inflated tyres are dangerous and can increase fuel consumption by up to 3%.
Plan ahead - Planning your journeys to avoid congestion, road works and getting lost and share journeys with colleagues and friends where possible.
Think ahead - Anticipate road conditions and drive smoothly, avoiding sharp acceleration and heavy braking. This saves fuel and reduces accident rates.
Gear up - Check your revs and use a higher gear before reaching 2,500rpm (petrol) and 2,000rpm (diesel).
Sparing usage - of air-conditioning significantly decreases fuel consumption.
Slow down - The most efficient speed depends upon the car in question but is typically around 55 - 65mph. Faster speeds will greatly increase your fuel consumption.
Cold start - Drive away as soon as possible after starting. Idling to heat the engine wastes fuel and causes rapid engine wear.
Lose weight - Accessories such as roof racks, bike carriers, and roof boxes add weight and significantly affect your car's aerodynamics and reduce fuel efficiency, so remember to remove them when not in use.
Avoid short journeys - A cold engine uses almost twice as much fuel and catalytic converters can take five miles to become effective. Walk, cycle or use public transport for short journeys.
Switch off - If you're stuck in a jam or waiting for someone, switch the engine off if you expect to be there for more than a minute. Cutting the engine will save fuel and reduce emissions.
