Mercedes-Benz is a company often portrayed as being deeply conservative, though in fact, no other manufacturer has such a record of innovation. Today, the brand is bolder, more forward-thinking and younger in feel, attributes very much in evidence in this fourth generation version of its smallest A-Class model. This car's now pitched even more directly against sporty premium compact family hatches like Audi's A3 and BMW's 1 Series thanks to key new driving features, plus sharper looks, extra media connectivity and greater efficiency. There's now the option of a saloon body style too.
