Fuel-efficient cars

125 articles · Page 1

This section covers cars chosen for low running costs and low emissions: hybrids, electric models, diesel and petrol, and alternative fuels. Articles compare real-world MPG against official figures, break down fuel and charging costs, and weigh emissions across a vehicle's life rather than at the exhaust alone. You will find hybrid versus electric comparisons, guidance for commuters and city drivers, buying advice for eco-friendly models, and examinations of common claims about green cars, including when keeping an existing car is the lower-impact choice. Fuel cost and mileage calculations, diesel pros and cons, and emissions comparisons between models are recurring themes throughout the collection.

Frequently Asked Questions

Is a hybrid or an electric car the better choice?

It depends on how and where the car is driven, since hybrids and electric cars differ in fuel and charging costs, emissions and suitability for long commutes. Articles here compare the two on real-world running costs rather than official figures alone. The comparisons cover city driving, long-distance commuting and total emissions.

Why does real-world MPG differ from the official figure?

Official fuel economy figures come from standardised tests, while real-world MPG reflects actual driving conditions, speeds and journey types. This section reports real-world MPG alongside official numbers so the gap is visible. Fuel cost and mileage calculators are used to translate those figures into running costs.

Is buying a new eco-friendly car always greener than keeping an old one?

Not necessarily, because manufacturing a new vehicle carries its own carbon footprint that has to be offset by lower running emissions. Several articles audit this trade-off and identify cases where keeping an existing car is the lower-impact option. The analysis also addresses greenwashing in how green credentials are marketed.
