The annual Which? survey polled 49,000 car owners in the UK about more than 58,000 cars in 283 categories, quizzing them about durability, breakdowns and the time their cars spent off the road. The survey also analysed repair costs, common faults and how satisfied owners were with their cars overall.
Winner of the category of most reliable medium car of models under three years old, the Toyota Auris scored 98.8% for reliability, spend an average of just 0.01 days off the road each year and had an average annual repair cost of just €3.80 (£3.00). For cars over three years, Auris Hybrid topped the poll with a reliability score of 95.8% and just 0.05 days off the road each year.
The Toyota Verso topped the MPV class for models under three years old, scoring an impressive 98.5% reliability in the poll and averaging annual repair costs of €14.00 (£11).
Topping these two categories meant that Toyota claimed top manufacturer honours jointly with one other car brand.
Scoring highly elsewhere was RAV4 which came second, just 1% behind 1st place, in the list of most reliable SUVs under three years old, with a 97.7% reliability score, and Avensis which topped the list of most reliable large car over three-years old, with a 97.0% reliability score. Finally Prius Plug-in topped the Which? list of most economical large cars averaging 78.5mpg in Which?’s real-world mpg test.
