Driven: Toyota Aygo (2014)

When the original Aygo launched in 2005, it shared the A-segment with nine rivals, including its sister cars, the Citroën C1 and Peugeot 107. In 2014, there are 20 small city cars on the European market, placing extra pressure on the Aygo's designers to ensure it offers something unique and competitive. But while the design rethink needs to move the car forward, pragmatism dictates that a truly successful reinvention will ensure the Aygo also remains integrated with Toyota's line-up; it's one of the top sellers in Toyota's European portfolio, and a proven driver of brand loyalty.
