Changing tastes among car buyers over the past decade have revealed rocketing demand for smaller cars that has reshaped traffic on Britain's roads.

Traditional segments including lower-medium and upper-medium vehicles have fallen in terms of their share of the overall car market, while minis, superminis, and even specialist sports cars have seen their share grow.

Superminis are now the most popular car in the sales charts, overtaking lower-medium cars which topped the charts in 1004. In terms of percentage growth, MPVs have seen the biggest surge, rising from 0.7% to 4.3% of the market. And despite environmental pressures, luxury saloons have retained the market share today that they enjoyed 10 years ago, at about 0.5%.
