Fuel economy
With the P- and R- series trucks, fuel economy has been further improved by up to 3 percent. This, thanks to improved aerodynamics, smarter control of engine auxiliaries as well as a lighter truck.
Aerodynamic characteristics have a significant bearing on fuel economy - especially vehicles that travel over long distances at consistent speeds. Scania is constantly investigating new methods of minimising air turbulence. The design of the cab is a key factor for a truck’s aerodynamics. The cab must be streamlined with the chassis as well as bodywork and various types of trailers. In the R-series, a new roof air deflector reduces wind resistance by deflecting more air above a high semi-trailer, for example. Also, the integrated underrun protection is equipped with a wheel spoiler for better air deflection.
There is a more intelligent use of electronics. The new electrical system is based on CAN-bus technology which means that all vehicle-based computers interact on a common network. This paves the ground for future developments in many ways not least in terms of fuel economy and emissions.
Less chassis weight allows more payload. Weight reductions are being steadily introduced on Scania vehicles. Over the years we have managed to reduce the average weight of a 4-series truck by some 400 kg. With the R-series we take another step; lighter cab components, a lighter frame, new air suspension, and a new fifth wheel that is mounted directly on the frame, save up to 270 kg on a tractor unit.
Emissions
As from September 2004, Scania customers can choose a truck with very good environmental performance that complies with legal emission requirement that enters into force 2006. Scania's Euro 4 engines feature emission reductions of NOx by 30 percent and by 80 percent of particulates compared with Euro 3. Read more
Hazardous substances
Scania strives to prevent the use of hazardous substances in our trucks. When developing the cab each design engineer has checked the chemical content of the materials used. The ambition has been to phase-out hazardous substances. One example is the integrated steering wheel lever where a polybrominated diphenyl ether used as flame retardant was phased-out. Read more
End-of-life treatment
Although it may seem distant today, the trucks will be dismantled and recycled one day. Scania has produced dismantling information and material labelling for its trucks for several years to guide dismantlers to perform end-of-life treatment in an environmentally suitable and safe way. Read more
