Peugeot is the oldest existing car brand in the world, having started producing cars in 1891, and has perhaps the most diverse history. Founded in 1810, the iron foundry produced saw blades, watch springs, tools, irons, sewing machines and - to this day - coffee grinders, pepper mills and bicycles. In 1929, the Peugeot 201 was the first model with the typical centre zero in its name. In 1974, Peugeot acquired a majority stake in Citroën. Two years later, the two companies merged to form the PSA Group. If you believe the British TV programme ‘Top Gear’, Peugeot's post-war history can be divided into three phases: first extremely robust cars, then extremely sporty cars and finally extremely lousy cars.
