One of the most famous Volvo trucks of all time was the "Titan", which was introduced in 1951. It played a pioneering role when it became one of the first trucks in the world to be fitted with a turbocharged engine, in 1954. The result was astonishing: with an increase in kerb weight of just 25 kg, the engine output was increased by 35 bhp (from 150 to 185 bhp).
