Scania Streamline: The Changes in Detail
• Aerodynamic improvements for the cab • New lighting solutions front and rear • Low-drag gearbox • New Performance Modes for Opticruise • New seats, and cabin trim refresh • New air suspension control unit
Scania has further refined the airflow around the front and along the sides of the R- and G-series cabs to lower drag and cut fuel consumption. In addition, a redesigned sun visor with improved airflow and a new set of optional auxiliary lamps is introduced on all cabs.
A new range of premium seats and revised interior colours enhance comfort and well being for drivers and passengers.
Scania’s aerodynamics specialists took a close look at all imaginable areas for further productivity and fuel consumption improvements. Despite the fact that the Scania R- and G-series are two of the most aerodynamic truck ranges on the market, the Scania experts identified areas where air drag could be significantly reduced.
The modifications involve smoothing the cab corners to pass the airflow onto the cab sides with minimum resistance. However, some (good) turbulence is needed to keep dirt and spray off the door handle. The solution to this requirement is a patented deflector lip located just above the headlights. The lip includes a duct that generates the right amount of swirl. The air enters above the light unit and is forced to swirl to create an anti-spray barrier.
The deflector lip is adapted to the different heights of the G- and R-series cabs. On the 16-litre V8 models, the lip features a chromium insert to complement the other frontal V8 styling accents.
The new aerodynamic corner treatment and sun visor reduce fuel consumption at cruising speed by up to 1% on the Scania R- and G-series.
The new sun visor, applied to all vehicles, R-, G-, and the P-series, also refines the airflow and sharpens the look. The ends of the sun visor have been opened up to allow air to escape along the sides of the cab, a revision that also serves to reduce wind noise inside the cab.
All attachments have received attention, as well as the integrated spotlights and LED marker lights. The new spotlights are not just stylish – they also feature an improved, more relaxed beam pattern, both close to the truck and at a distance.
The new spot lamp has been developed for high mounting. It is adjustable both vertically and laterally. The underside is fitted with a cover for easy access for bulb exchange.
It is now possible to specify the identification lamps in combination with the spot lamp.
This will be the standard specification on all V8 models and an option on all other trucks.
Other styling changes at the front include new headlight units, with new bezels, LED indicators and daytime running lights. Light options include H4, H7 and Xenon, with H7 the standard for Australian specification trucks.
The new H7 headlamps have two bulbs, an H7 bulb for dipped beam and a supplementary H1 bulb that is turned on for main beam. The lenses are clear glass. The headlamp units incorporate direction indicators, LED Daytime Running Lights and LED position lights. Separate side-indicator lamps are located in the boarding steps.
New unique LED tail lamps are being introduced as standard across the product range. They are shaped to mimic the Scania styling traits at the front, and provide an extra fuel saving of up to 30 litres per year (due to reduced power consumption), as well as a long service life and higher reliability.
The LED tail lamp has been designed to last the truck’s lifetime. The circuit board is covered with a special gel that will keep out water and dust. This preventive measure will ensure lifelong durability.
Another fuel saving improvement is the new low-drag gearbox that is introduced as standard.
The original intention with this project was to have better lubrication of the gearbox. However a resulting benefit is reduced fuel consumption as a result of lower friction levels in the gearbox due to the reduced oil capacity.
The new way of circulating oil in the gearbox reduces splash losses by 25%. This is done by lowering the oil capacity and implementation of new guiding plates for the oil that ensure full lubrication in all locations, as well as keeping the oil on the gears for longer time.
This gives much better cooling and the temperature can be reduced by as much as 20-degrees on the gears.
This translates into fuel savings of up to 0.4% in high-speed operation such as long-haulage.
The change will be applied to all 8- and 9-series gearboxes, with the exception of some specific applications such as mining.
The oil level will be fixed by the position of the oil level plug. On 8-series gearboxes the level will be lowered by 13 mm and for 9-series, 19 mm, reflecting a reduction of gearbox oil capacity of 3.0-litres, which also brings a cost saving in lubricant refills during service.
Fuel economy benefits of 25% less internal drag translate to savings of:
-0.3% in construction applications
-0.1% in distribution
-0.4% in long haulage
-0.1% in public & special service sectors
The new gearbox will manage hilly terrain and hot climate situations better, despite the lower oil capacity. However, operators will have to pay close attention to maintenance of the correct oil level.
The new low-drag gearbox has been subjected to exhaustive testing by Scania, including running ‘lifetime’ testing on 16% grades. The results have been excellent.
In line with Scania's ongoing product refinement, customers have access to a new range of Scania-designed premium seats representing the ultimate in truck comfort.
In-cab enhancements include Bluetooth connection, new upholsteries and more subdued trim colour schemes selected to create a calmer atmosphere in the sleeping area.
The new Scania line of premium seats offers the perfect combination of comfort, style and convenience, as well as typical Scania ergonomics. The new premium seat is standard on all Australian prime movers delivered with engines above 400 hp.
The seats are unique Scania-styled designs produced by European seating specialist Recaro.
Styling is state-of-the-art, with a smart selection of upholsteries that match the other interior fittings.
The seats adjust in fine steps in all directions, and are available with two-stage ventilation. The seat squab is wide and the lumbar support is fairly pronounced for greater comfort.
In conjunction with the introduction of the new seat range, the interior colour schemes have been reviewed to provide new choices and a fresh look.
The standard seats will be dark woven material with the options of sand coloured velour-type upholstery, as well as leather.
The wall and roof panels are manufactured in a new material and a darker shade is being introduced on the walls in the sleeping area to create a more subdued ambience. Special dashboard and sill strips are fitted on Scania Streamline.
Scania's pullout bed with extra-thick pocket-spring mattress offers exceptional comfort and is fitted as standard on Scania R-series sleeper cabs.
The bed pulls out to full width even when the driver is seated on it. Sleeping comfort can easily be tailored to individual drivers, without encroaching on the highly adjustable driver station.
Bed width is adjustable from 730 mm to 900 mm. The width adjustment can also be used to adjust the softness of the mattress. The bed can be expanded to its full width even when the driver is seated on it.
New Air suspension controller
A new electronic level control system is being introduced for the air suspension equipped versions.
The new remote control handset has four memory press switches. Two performance steps are offered – basic and fast – the latter suited to applications that require frequent operation of the air suspension system.
Another new feature is the load handling function. Load transfer is being introduced between triple bogie axles.
This is a two-step procedure, first transferring from tag axle to bogie axles and then between driving bogie axles to provide extra traction.
