Once again, the Which? Car Survey takes the top spot as the UK’s biggest round-up of car reliability and satisfaction. This year, more than 49,000 car owners told us about 58,055 cars.
The Which? Car Survey is essential reading for anybody buying a new or used car. We rate 283 car models for durability, breakdowns, faults and time off the road.
We also rank the car brands according to Which? test scores and owner feedback. And we reveal the most efficient cars in each class, based on our realistic fuel economy tests.
- The Citroën C1 supermini was the most reliable new car of 2014, with an impressive reliability rating of 99.3% for the first three years.
- BMW and Toyota take joint manufacturer honours; both came top in two of the eight car classes we looked at.
- Six of our eight highest-scoring new car models had no reported breakdowns last year.
- The Hyundai iX20 diesel was the least reliable car up to three years old, with a score of 75.2%.
Editor of Which?, Richard Headland, said:
‘Choosing an unreliable car could cost you time and money.
‘The Which? Car Survey 2014 is the UK’s biggest survey of car satisfaction and reliability. This year, the Citroën C1 takes first place as the most reliable new car. However, it has just been replaced by a new model, so we’ll be interested to see how the latest C1 fares next year.
‘Hybrid cars continue to score well, plus there’s an overall trend for petrol engines being more reliable than diesels.’
