Citroen to launch '3CV' plus DS3 cabrio, DS4 SUV, DS6

Citroen is working on a '3CV', a radical new entry-level model positioned between C1 and C3. Imagine the previous C2 pepped up by the glittery polish that's made the DS3 such a success, and you're not far off Citroen's new city car vision.

Thanks to a canvas roof and carbon fibre rollover bars, the weight penalty for the Spider is only about 60kg (around a 7 per cent gain) which shouldn’t hurt performance too much.
