Most reliable new supermini revealed

The best small cars for reliability in 2012

Citroen C1 1

Improved fuel economy figures and lower CO2 emissions, that equate to cheaper fuel costs and car tax, have contributed to the growing popularity of the superminis.

Reliability is another key reason to buy a small car – they regularly claim the top spots in our annual reliability survey. In fact, the average reliability score of all the small cars reported on in the latest Which? Car Survey was an impressive 89%.

Most reliable new supermini: Citroën C1 (05-)

The Citroën C1 has topped the reliability charts for the past two years, with owners awarding it a score of 96.9% in the latest poll. 

And not a single breakdown was recorded throughout the year, meaning you can be pretty confident this little city car will get you from A-to-B successfully, if it’s under three years old. There were some minor faults, such as split rainwater seals, but repair costs for these averaged out to just £8 for the year.

Toyota iQ

Least reliable new supermini: Toyota iQ (08-)

In 2011 the Toyota iQ was one of the most reliable superminis featured in our survey. The past 12 months were not so kind to the diminutive city car – a recall from Toyota meant it slipped to the bottom of the table with a lowly score of 66.3%. With nearly a third of the faults reported on relating to this recall work we expect the iQ to return to steadier ground this year. We also applaud Toyota for being pro-active in issuing recalls in the UK.  

The Smart ForTwo (07-) was the only other supermini to record a reliability score of less than 70%. This isn’t a one-off though, so we would recommend steering clear of this model if you want a car you can depend on.
