The Scania 3-series is a truck model range introduced in 1987 by Swedish truck manufacturer Scania.

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.

The Scania R143 is generally considered to be the best European tractor unit of its time.

It is affectionately honoured by truck enthusiasts and has an unwavering reputation as a reliable and groundbreaking workhorse.
