6. Ford Focus: 222,834 sold

The Ford Focus - the UK’s second favourite car - remains as popular as ever and, thanks to a series of enhancements for 2015, remains on top form. It’s no longer the sharpest five-door hatchback you can buy, but a strong engine line-up and an array of innovative technologies means it’s likely to enjoy another solid year in 2015. And the blistering new ST hot hatch, along with the forthcoming RS, will undoubtedly help reverse the small 0.6% drop in sales in 2014.
