There has been rapid change in this sgement recently. Toyota has launched the Auris HSD - basically a petrol Auris fitted with the Prius hybrid drivetrain. There have also been major developments in conventionally-powered models. The first sub 100 g/km small family car appeared in 2009 and there are now five such models to choose from. As stop-start technology becomes more widespread, this number will grow steadily. The lure of free road tax is so strong that no major manufacturer will want to be without a sub 100g/km model for much longer.
