Ask anybody with even the slightest familiarity with cars about Citroen, and one thing's for certain - they'll start to talk about the way in which they differ from their competitors.
They might say "quirky", they might say "weird", they might say "years ahead of their time" - but they will certainly recognise that Citroen have long been unafraid to think outside of the box.
Even back in the very early days, Citroen were one of the very first manufacturers to use mass-production techniques and provide extensive social benefits to their staff, through the mass-market introduction of now universal ideas like FWD and monocoque bodyshells. Then, of course, came the DS and the 2cv. Like nothing else on the market, then or since.
As the '70s rolled around, the GS and SM continued to plough their own furrow, then the Peugeot era started to turn it down a bit. Even so, the AX and BX reminded everybody that there were still massive efficiency gains to be had, just by shedding a bit of weight. As computerisation started to bite, every manufacturer started to add gadgets by the shedload. Citroen, though, continued doing things their own way - the Pluriel solved several questions nobody had asked, and the C6 asked (again) why luxury cars had to ride like sports cars.
