We got quite excited when we saw the headline of the Citroen announcement.

However, it turns out Citroen has "done a Fiat 500" and added a fabric roof to the DS3 which rolls back all the way to the boot. The doors and windows stay the same as the hatchback as do the outer edges of the roof, so you do not get the full cabrio experience of, say, the Mini.

The advantage of the "maxi-sunroof" approach is that the interior and bootspace of the hatchback is largely preserved, and the cost premium should be lower (prices are yet to be announced). Citroen claims that the DS3 Cabrio features the largest boot in its class at 245-litres and even retains the 60/40 split-folding rear bench. There is also little extra weight (just 25 kg), because little extra bracing of the bodywork is required – Citroen says a full fabric convertible would add 100 kg.

Three soft-top roof styles will be available - black, Infinite blue and a DS Monogrammed design. The Infinite blue soft-top uses three different coloured threads - one of which is shiny - each reacting differently to changes in light conditions and creating different hues of blue and violet.

The electric roof takes only 16 seconds to fully close, and can be operated at speeds up to 120km/h (75mph). A button on the overhead console opens the roof to three positions: intermediate, horizontal and total. Even in the horizontal setting, rear passengers get a completely clear view overhead.

The new car will go on sale in early 2013.
