Citroen DS3 Cabrio (2012) first official pictures

Britain is Europe's biggest market for convertibles - odd, given our recent blink-and-you'll-miss-it summer. Still, Citroen hasn't been put off, and will launch the DS3 Cabrio after its world debut at the 2012 Paris motor show. Citroen claims the weight has only increased by 25kg over the hard-top DS3, and buyers will get even more personalisation options to go along with the wind-in-the-hair driving experience.

Some hybrids are not a green as they seem, interest group says

Car buyers who think they are helping the planet by choosing a hybrid vehicle to aid in cutting emissions don't always get the biggest bang for their buck, according to an environmental interest group.

These not-so-green hybrids compromise their value or eco-friendliness in a variety of ways.

IAM Highlights Concerns Of Driving With Dementia
