Which? Complete Guide to Greener Driving

Driving a greener car will save you money as well as help the environment, says the new Which? Complete Guide to Greener Driving.

The Which? Complete Guide to Greener Driving has revealed the top 10 cars for fuel economy out of the hundreds of cars tested by Which? since 2006. 

The 10 most fuel efficient cars are all diesels. Although diesel cars cost more than petrol cars, better fuel economy means diesel cars save drivers money if they cover lots of miles. A Peugeot 207 driver, for example, could save £247 on fuel over 10,000 miles by switching from a petrol engine to the HDi diesel alternative.

You can also save money and reduce your car’s impact on the environment using greener driving techniques – find out how in our greener driving advice guide.

Fuel economy top 10

Which? fuel economy tests, more stringent than EU official measurements, reveal the 10 best cars for fuel economy out of all vehicles tested by Which? since autumn 2006:

  • =1 Fiat Panda 1.3 Multijet, Toyota Yaris 1.4 D-4D, VW Polo BlueMotion 1: 60.1mpg
  • 4 Mini Clubman 1.6D Cooper: 58.8mpg
  • =5 Audi A3 1.9 TDIe, Mazda2 1.4D, VW Golf BlueMotion: 57.7mpg
  • 8 Vauxhall Corsa 1.3 CDTi 90: 57.6mpg
  • 9 Fiat 500 1.3 Multijet: 56.5mpg
  • 10 Renault Modus 1.5 dci 86: 55.3mpg

Fiat, Toyota and VW have produced models that break the impressive 60 miles per gallon (mpg) barrier. 

Cheaper driving

Green car drivers will also save money on tax as the government plans to bring new road tax rules in 2009 to encourage motorists to drive cars with lower carbon emissions. A car which emits less than 100g/km – such as the VW Polo BlueMotion 1 – will not be liable for road tax.

Richard Headland, editor, Which? Complete Guide to Greener Driving, says: ‘It’s a win-win situation. Choosing a greener car will reduce your carbon tyreprint, cost less in road tax and you’ll save money every time you fill up your car.’

The Which? Complete Guide to Greener Driving is available in selected WH Smith, Borders, Sainsbury’s, Tesco and Asda stores for £6.99. The Guide reviews the UK’s top 100 eco cars and is packed with practical advice on greener driving.
