What Car? says...
The Citroën C1 (in case you hadn't guessed from the photos) is in the competitive city car class – and that puts it up against some seriously strong rivals.
There's the Hyundai i10 and Volkswagen Up for starters, and as if those two popular models weren't enough to worry about, it also has to take on the Toyota Aygo and Peugeot 108 – stablemates from the Toyota Peugeot Citroën tie-up. The C1, Aygo and 108 share the same engineering DNA, with variations in styling, pricing and specifications to set them apart.
