Most economical petrol cars FAQs

A diesel car offers a fuel economy advantage on long motorway journeys, but for short journeys around town the difference between the two is far smaller. Petrol-powered cars are also preferable to diesels for these short trips as diesels have a diesel particulate filter (DPF) which can clog up causing poor running and higher fuel consumption.

Not as a rule. Modern turbocharged petrol cars with direct injection technology can offer very impressive fuel economy figures, but a diesel car can still be slightly more economical on short trips.

As with any car, keeping to the recommended service intervals, ensuring that the tyres are at the correct pressure, and avoiding aggressive driving all help to reduce fuel consumption figures.

Idling for long periods, using the air conditioner constantly and labouring the engine in too high a gear (for manual cars) also adversely affects your fuel economy.
