The R-series model range debuted in 2004, and won the prestigious International Truck of the Year award in 2005 and again in 2010. The range offers various trucks optimised for long haulage. All models have a Scania R cab, and each vehicle is available as a tractor or rigid. There are different axle configurations and a choice of chassis height and suspension. The Scania R730, the most powerful variant of the R-series, currently holds the record for the most powerful production truck. Its 16.4 Liter DC16 Turbo Diesel V8 engine produces 730 PS (540 kW; 720 hp) at 1,900 rpm and 3,500 N·m (2,600 lb·ft) of torque at 1,000 - 1,350 rpm.
The R series also came as a limited edition '+' the most common being the R420+ with 100 being sold across Europe. This came with a newer opti-cruise gearbox with a trial gear ratio. It also came with an added microwave from the dealer. It's believed the sales were mainly in Sweden, but as many as 10 per country elsewhere.
In the 2013 Scania lunched the new face of R-series with the name Streamline. Has not changed much of overall design of the truck. It is aimed to the fuel efficiency. With its new low-drag looks and full air deflector kits and with new Opticruise from Scania claimed that the fuel costs can be reduced up to 8%.
