As if those two weren't enough to worry about, the C1 also has to take on its stablemates, the Toyota Aygo and Peugeot 108. With all three cars sharing the same basic engineering DNA, it’s only the cars’ styling and pricing, and the small differences in their specifications and trim, that will matter to customers.
Two three-cylinder petrol engines are on offer: a 1.0-litre 68bhp petrol, available with either a five-speed manual gearbox or a five-speed ‘ETG’ automated manual, and a slightly more powerful 1.2-litre petrol that produces 82bhp. Both attract zero road tax.
To reduce its emissions further still, the entry-level motor, called the VTi 68, also has the option of engine stop-start. However, if you want this low-emission model, it’s only available in top-spec Flair trim.
The C1 comes in a choice of three or five doors, and there is also an open-top Airscape version which has a retractable fabric roof. Read on over the next few pages to get our in depth impressions of the C1, and to see how we think it compares with its rivals. We'll also pick our favourite trim and engine option.
