The 1.0-litre 60 PS three-cylinder petrol is efficient for city work, with official combined consumption near 4.4 l/100 km and CO2 around 102 g/km on later Euro 6 cars. Ecomotive versions with stop-start improve the numbers further. Real-world figures stay strong if driven gently.
Servicing follows a fixed 15 000 km or annual schedule for oil and filter changes, with larger inspections at longer intervals. Parts and labour stay modest for this simple group car.
Safety starts with four airbags, ESC and ABS as standard on later cars, plus ISOFIX and belt reminders. The 2011 Euro NCAP test gave five stars. Optional City Safety Assist adds low-speed automatic braking.
