The Scania 3-series is a truck model range introduced in 1987 by Swedish truck manufacturer Scania. It is the successor of the 2-series.The 3 series came in a range of different engine sizes and horsepower from 9.0 litre 230 horsepower all the way up to 14 litre V8 500 horsepower engine. Production of the 3-series was stopped after the 4-series were introduced in 1995. The 3-series was the first series of Scania trucks to use the Streamline name, aiming to improve fuel efficiency and keep the styling up-to-date. The most notable changes were a redesigned bumper and front fascia incorporating a lower-drag grille design and full headlight bezels and an improved cab-side wind deflector design.
