The new generation magistralnikov: test drive Scania S730

Held just before the French presentation of Scania’s, which main tractors of new generation were presented, was bright and exciting in all but one – then no one could get behind the wheel. But in Sweden, Södertälje, we have come with a specific and foreseeable purpose: to conduct a full-scale test on the roads of varying quality and fully loaded trucks.

H ovoe generation Scania waited more than 20 years. Next, the fourth series appeared in 1995 and went through two restyling (2005 and 2013). Logically, the new Scania should have been called a “fifth” generation, but the Swedes have avoided this name and limited the term “new generation» (New Generation).

Before the trip to Sweden, I was sure that only refreshed cabin – the more that just three years ago restyled version of the Scania Streamline has been shown with the most advanced solutions … However, the changes were much more – it’s really a new car. 20 billion SEK (about € 2 billion), who went to the development of a new generation, not spent in vain!

 

The subject of debate

Scania The new design leaves no one indifferent – in the range of opinions is very different: as expected from the evaluation of “cool” to “sucks” and “ruined bench” … In fact, that reaction is predictable – exactly the same opinions were expressed, and after a new generation of premiere Mercedes Actros MP4 2011 and Volvo FH in 2013 … Perhaps the assessment there were even sharper. But it took several years, and the new Mercedes and Volvo are already familiar. The same is likely to happen with Scania. The fact that the main carriers – some of the most conservative groups of customers, their only conservative bus owners – they did not like innovations.

So the design – it is a matter of taste, and though he is interesting, but not in the first place. Much more interesting functionality – and here it is, a story to tell. To begin with, the new Scania is now sports a four-storey light engineering: the combination of working and if the fog lights in the bumper and underneath it has long been customary, the new generation of trucks were added to LED running lights, which is also expected. But more … Narrow triangles under the windshield – it’s not the size – a main-beam headlamp! The same can be said about the lights in the upper corners of the cab. In general, even in the polar night extra “chandelier” is not required.

The windshield was just as flat as in the predecessor – and that is good, and in combination with the fact that the driver’s seat shifted forward visibility is even improved. Large mirrors eliminate blind spots, and additional mirrors on the passenger door and the windshield now equipped with electric – can be parked close to the curb, without the risk of crushing anything.

It completes the appearance of evidence of serious work on the aerodynamics: side walls covered with metal shields.

The chassis is completely rearranged: a tank with a synthetic urea was moved under the frame, brake receivers hidden between the side members, and the batteries were placed in the rear overhang. Outside the frame leaving only the exhaust system and two fuel tanks with a maximum capacity of 1 500 liters. In addition, the wheelbase to improve weight distribution increased by 50 mm.

Location

To get to the “top-end” cab, it is necessary to overcome the four steps, two of which overlap the door. The largest cabin is now called: «S-series.” Here, a flat floor and inside height 207 cm Prostor -. Unreal, even to reach the passenger – a problem. At Scania «the fourth series of” fit and range of the steering wheel and seat adjustments were the best in the class – it instilled fear that parameters can be changed for the sake of design … but they proved unfounded in the new generation – a huge range! You can sit in the car, the driver’s seat completely down to the floor and raised his maximum wheel – and it is possible vice versa. The maximum height of the driver, which is calculated “skanievtsy” – 212 cm!

This is not just another “tail” on the old frame – it really is the new cab. At the moment there are two versions: as they are called themselves “skanievtsy”, “20-inch” and “17-inch”. Both are equipped with beds, but first, you guessed it, a little more, and it has gone in sliding sleeping berth width of nearly 1 meter. In addition, there are three roof heights. Later for construction equipment and delivery trucks will show “Daytime cab” without bed.

Plastic finishing machines in all soft and flawless sound and vibration – unlike some competitors, everything here is really very good.

Of course, the list of options – length and weight variants – from the simplest to the plastic wheel and “rag” to most expensive seats, fully trimmed in leather and equipped with a coffee maker, microwave, television, refrigerator and hundredweights other options.

I went for a test just top-end configuration, and easier to say that there was no – there was no coffee maker. Everything else, including the refrigerator and the plate was.

Sleeper – another reason to look into the cockpit. It has cutouts at the back of driver and passenger seats: width shelf behind the back of about 55 cm, and in the middle – 75 cm bunk Length – 215 cm.! The S-Series cab seats are moved forward in one motion, and the bed can be further separated into 20 cm However, efforts at the same time it is necessary to make childish -. Pen, which accounts for the pull is too small.

Working space

When the bed moves with the steering wheel, you realize that the “center of the universe” is still here. The top configuration itself is decorated with high-quality leather steering wheel, very pleasant to the touch. The cross-section shape and can be regarded as optimal, and the lower segment of the steering wheel is cut – not in sports, but rather based on the beer lovers with bulky bellies.

The wheel, of course, located media center controls, on-board computer hands-free system and active cruise control. Devices which have kept the same layout as in the version of the Streamline, still clearly readable in all lighting conditions – it is, however, a note from the formal discharge.

But right stalk switch several overloaded: it is derived management automated Opticruise gearbox can be switched to manual mode, plus a retarder control and two-stage engine brake – to have to get used to this.

But the “hammer” was familiar and sticks on the front panel. The developers have assured us that soon will be “key” – is the same as its competitors. But so far, according to the chief designer, “customers – people are conservative, and they wanted to see a normal handbrake lever on the front.”

The very front panel on “skanievskoy” tradition deployed to the driver, and to use the secondary functions, it is not necessary to tear off the back of the chair. A lot of these functions. Multimedia Complex except navigation with three-dimensional maps of European and good equipped with Bluetooth-channel radio system – now the driver can connect to the handsfree system is not only a service but also personal phone. And in order to charge it, the front panel has as many as three nests with USB-connector, plus one on the rear wall of the cab. In general, discharged gadgets in the cabin will not. Under the media center panel is climate control and powertrain controls. Buttons all happened a lot – but still less than the competition.

And here we come to the fun. The remote control mirrors, windows and light located on the left … the windowsill! Yes, it is on the driver’s door. Enjoy all these pretty comfortable, but … What if the buttons and joysticks flood water?

How to behave in the wire loopback driver’s door? These questions we asked designers and engineers – their response can be translated like this: “All of these features were subjected to multiple tests, both mechanical (opening and closing of doors, pouring water) and thermal (heating and cooling), and it should work in the staffing order “… In my opinion, the solution is more than ambiguous.

Driving force

Under the new cabin – new engines: a 13-liter inline “six”, the maximum capacity of which was adjusted to 500 liters. s., and the torque to 2200 Nm, and the 16-liter V8 (the only one in the world that performs Euro-6 standards), spanning a power range in 520-730 liters. from. The new engines have refused the exhaust gas recirculation (EGR) system and achieve Euro-6 standards only by means of the injection of synthetic urea AdBlue into the exhaust tract (SCR technology).

Technical educational program titled article so I, of course, ready for a wild burst of emotion in the comments to this material, with the charges in my technical ignorance, lack of foresight and remarkable …

To achieve this, we had to do a lot of work. Compression ratio was raised to 20.1: 1 – this is very much for the heavy truck turbodiesel! Moreover, engineers have optimized the combustion chamber, refused Variable Turbine Geometry, fully modernized system of intermediate cooling of air (intercooler) and increased radiator area. The engine is quite hard mode, but the developers promise that it will save up to 3% fuel.

Branded “skanievskuyu” automated transmission OptiCruise did not change – and so it is the best in the class. Not for nothing have 2018 MAN abandons its own transmissions, and their trucks will put it OptiCruise.

Drive axles, too, have remained the same, the only innovation – the ability to order a main pair with a gear ratio of 2.35: 1. But such machines Russia irrelevant – it is economical for the main pair of good European roads, where you can use Trunk trucks on 18-inch wheels, and routes run across the plain. Last fleeting remark about technique: service brakes – of course, disc on all axes.

Movement in life

The fact that the presentation of the First World customers have not given train – big omission marketing department, new Scania revealed just in motion. Only in motion can be estimated and excellent noise and vibration control, and correct operation of the automatic transmission, and maneuverability of the new long-haul tractors.

It so happened that the first truck, which I drove on the highway, turned out to be super-heavy (64 tons) and extra-long (24 m) “Scandinavian” trailer – these machines can go on the road in Sweden, Norway, Denmark and Finland, and in the rest of the world their operation is prohibited. But we in Sweden, and now that chance turned out to be, it is a sin to miss it.

The first thing to note – this is a very unusual feeling: have to go “on the mirror.” But you know what strikes the most? The fact that the entire coupling behaves monolithically, and no habitual twitches, reminding the driver that the car reaches a rather big tail. And the second – just what the Swedes have managed to calculate the kinematics of the trailer, that all his five axes are exactly on the trail of the head of the machine! It is fantastic. And yes, the 730-hp V8 engine (3500 Nm) of Scania does not feel this gravity! Later, I specifically checked their impressions on a conventional 16-meter eurowaggon: Yes, the dynamics a little bit down, but on the descent retarder can be activated not until the end, and for a couple of degrees less – but on the whole machine behaves predictably and 64 tons total weight just does not felt.

It is like a modernized retarder. This whole system was activated at different stages and the service brakes, and transmission (actually, retarder), and engine brake. Brake system is activated at the beginning to prevent the “folding trailer” on the slippery slope – and then braking is only due to the transmission. At 8% downhill 64-ton tractor-trailer confidently holds the set speed, and the workers have to use the brakes only to a complete stop.

And, as is customary in Scania’s, as soon as the retarder, completely cuts off the fuel supply. This is the real economy, and the fuel and brake pads.

Simple human sensations of driving the most positive – noise insulation and suspension work fine. The car just floats like on an asphalt road and on the pavement “Brussels pavement.” In any movement in the cockpit mode you can talk without raising his voice – a few cars can provide a level of comfort.

Summary

The car turned out well, comfort, economic and environmental performance at a height – in general, everything is great. However, no one has been able to say how many such beauty is worth, because these machines will appear with engines of Euro 5 and earlier in Russia than a year. In the best case – the fall of 2017, and, most likely, – since the beginning of 2018 year.

In Sweden the price of top-end Scania S730 is located at 150 thousand euros. Expensive? But Scania has never been cheaper – it’s a real premium. And it is worth the money. And so I think I’m not alone: ​​those carriers, which was able to talk, are willing to purchase this machine right now.
