Hybrid vehicles - promoted as the planet's eco-saviours - are not as economical as common diesel models.
Results of a test by British green motoring website Clean Green Cars showed that the Toyota Prius had a real-world consumption figure of just 7.8l/100km despite its claimed figure of over 4.7l/100km (60mpg).
When tested against a diesel SUV, the Jeep Patriot, the Patriot managed marginally less over the same journey, recording an average of 7.26 l/100km.
