It’s over 20 years ago, Scania last viewed a new truck. As the first newspaper, new technologies have been test drive and inspect the new Scanian the seams.
The test car is still wrapped in specially made coveralls when Ny Teknik’s team enters the four steps up into the cab. Masking tape covers a part of the side windows, and dampen the sought safe sound when we close the door on us.
While Scania Project Manager Lars Bygdén talks about all the new features and options in equipment and instrumentation we set the driver’s seat and the steering wheel and pull away with 60 tonnes of the trailer.
Scania has changed a number of things that affect the run positively, but individually it is difficult for an inexperienced driver to point to one of the feature or the other. The driver’s seat is moved slightly forward and to the side, the glass panes are larger, more efficient brakes, steering and handling have been improved. Safety has improved with side-mounted inflatable curtains.
Overall, a first impression is that it is incredible how easy run to make such a heavy truck. The steering wheel exudes luxury, and the heavy rig does exactly what I ask for, no more, no less.
– The biggest engineering challenge was to move the front axle 50 millimeters forward, and the driver 65 millimeters. All components are on the bulkhead in front of the driver, or below, and we have lost 80 liters pack volume. But that’s where we won 5 per cent shorter braking distance, says Lars areas.
The new Scanian also 2 percent lower drag than their predecessors. Despite, or rather because of, that it has an even flatter front than the old one.
– It has to do with how the air goes around the corners here, says Lars Bygdén and points.
It is a huge task just behind the form. A thousand different versions have been measured in the wind tunnel, Scania has conducted computer simulations 3000 à 40 hours using 1000 computers in the cluster. While we’re on the figures: the whole car has taken 4500 man-years of development work; Thus eight million working hours.
Scania has built 200 test vehicles which have completed a million mil and in addition spent 26,000 hours in skakrigg and 20 000 hours of dynamometer. 5000 brand new article has been subjected to 40 000 hours of component testing. 25 percent of the development work has taken place virtually.
It all has taken ten years and cost 20 billion. Last Scania unveiled a truck with such large changes was October 14, 1995.
At the end of September, relieving the new car the older models at its plant in Södertälje. As usual, production has been in the design process, so the car will go well to build. For the first time, has also service organization got to be with.
– Service’s an increasingly important part. Their main demands has been to get a divisible stabilizer which allows one to access, for example, replace cooler without removing the entire cabin.
The new car is also prepared for electrification: there is a space set aside for an electric motor.
Lars Bygdén has led the project with the new truck from the time it went into the real situation seven years ago. When asked what he is most satisfied with the answer directly:
– It’s so handsome! And so it is fantastic to drive.
