PEUGEOT 508 Sedan test drive since 2010 sedan

The stone of Destiny. PEUGEOT 508 RXH Hybrid

This test was the shortest in my practice. At the wheel of a hybrid Peugeot 508 RXH, I managed to drive no more than 10 kilometers. And all thanks to its carelessness. And the organizers are good for preparing an off -road route to demonstrate the capabilities of the full -wheel drive transmission Hybrid4, they never let it go along it ... I had to look for bypass tracks.


Hybrid4 is a diesel-electrical hybrid drive that PSA Peugeot Citroen plans to install immediately on a number of serial models. It has already been received by Peugeot 3008 and Citroen DS5. Now the time of the universal Peugeot 508 has come, to meet with whom I went to Marseille. Large trunk, spacious salon, enlarged clearance, plastic body kit around the perimeter. PEUGEOT 508 RXH car for sorties to the cottage on dirt roads and light crossed areas. The anatomical features of the Hybrid4 all-wheel drive are such that the front wheels here rotates a two-liter turbodiesel connected to a six-speed robot, the rear electric generator engine operating with a traction battery installed over the axis. Logical move: neither you additional cards, nor gearboxes, nor cardan shafts ...


Why did no one make hybrids with diesel before? After all, the decision was asked for a long time. It is known that heavy fuel engines have good efficiency, efficiency and give out excellent traction at low and medium -speeds. The cheapness of fuel also plays into the hands of consumers. But not so simple. As part of the ICE hybrid, it operates in ragged mode. The engine for the sake of saving is constantly turning on, then it turns off. Moreover, shutdown often should be done right immediately after the engine has worked for some time in the maximum return mode. As a result of such bullying, the turbocharger suffers first of all.


At 508 RXH, instead of a tachometer, a scale that demonstrates the modes and efficiency of the drive. The scale is divided into three sectors. If the car slows down in the recuditive braking mode of the shooter below in the charging area. When you move at a constant speed on an electric motor or using two engines, an arrow in the ECO sector. It is worth sprouting, the index from the eco-zone will be immediately extended to the territory of the scale of indication of the efficiency of the drive. Numbers at the last percent of the traction drive


In total, four operating modes of the ZEV, 4WD, Sport and Auto hybrid drive are provided. The choice is made by a puck next to the transmission selector. In ZEV (Zero Emission Vehicle), Hybrid4 moves the car mainly by electric trim. ICE is connected only after reaching 60 km/h or when the charge of the traction battery runs out (the electronics then immediately falls into the automatic mode). 4WD involves start and movement on both engines at the same time, so it is best suited for off -road, snow, sand or slippery coating. In Sport mode, acceleration is most dynamic, here the electronics willingly holds a turbodiesel in a tone in reduced gears

PSA Peugeot Citroen coped with this issue. Firstly, the standard two-liter engine received a different management program, which provides for a decrease in boost pressure. Due to the reduced pressure, the maximum rotation of the turbine impeller and the load on the bearings are reduced. The latter are made of more hardy materials, and their lubrication and cooling are more effective. It doesn’t matter that Diesel lost its traction (the maximum torque here is 300 Newton meters, while the standard motor issues 340 nm), but it has become somewhat more economical and environmentally friendly.


When the battery is devastated, the hybrid moves exclusively due to the diesel engine. At the same time, the battery is recharged from the traction electric motor during braking and sometimes from an 8-kilowth generator (he is also a starter), which is given from the internal combustion engine. So even with an empty battery, the thrust on the rear axle will be supplied if necessary

On standard versions of Peugeot 508, I rode a year ago. The machine then liked the car with a clear control and an fearless attitude to the broken asphalt. A 115 kg hybrid is heavier (1770 kg versus 1655), he received other springs and shock absorbers with more rigid reptile stabilizers. Despite the increase in mass and road clearance (grew from 170 to 184 mm), the habits of the hybrid are slightly different from those in ordinary executions. It costs a lot. The 508th hybrid retained comfort, an informative steering wheel drive and lightness in reactions to the steering wheel. He willingly stands on the arc, you go along the winding serpentines on it without straining at all. That's what the school means! Although before the GT version (instead of the front MacPherson, parallel levers and a suspension tuned for active driving) is still far away ...


The trunk, compared with the usual version of SW, decreased in volume by 100 liters and now 400 liters (under the window sill with raised seats). The niche for the spare wheel had to sacrifice. Instead of a spree, a reprimatum is included in the compressor, sealant and anti -traffic shoes. Why a jack, when there is still nothing to change the punched wheels?

And what about off -road? As I said, the pezhoshniks were not allowed on a prepared off -road route. What was not clear! You can watch and photograph, you can’t touch it. Like in the museum, by God!

Get a ride!
Not a question, but only in a passenger place.

Of course, the brave test pilots turned out to be a spore. Tarized upsurges and descents, excesses on which wheels barely came off the ground ... Bravo! Such obstacles in inertia can be able to overcome even on a monopoly road sedan.


After such an off-road Ersatz test, I want to get drunk. Having went further along the test route, I immediately began to look for towns where you can fall off the asphalt down to feel the geometry and the possibilities of an all -wheel drive hybrid transmission.

Maybe we should not? Syuya, what it smells, prominently said Alexei Smirnov from Drive. The plane is soon!
It is necessary, Lesha, we must! ..

And here is a suitable place. Diagonal hanging on a steep climb showed that the 508th hybrid on two wheels up it climbs very zealously. The anti -wings system does not wake up until you carefully press the gas awaits the appropriate traction. But as soon as she joins, as the car immediately breaks down and begins to confidently crawl up. Well, commendable! Moreover, there is enough traction, even when the battery is completely discharged. In this case, an electric motor, which rotates the rear wheels, is powered by an 8-kilowatt generator, which is given from the diesel engine.

Having done the exercise at different angles of attack with different obstacles, I lost caution. Sucking! Having crossed the shallow sizes, I firmly attached the front part about something solid in a grand scale! Christmas trees, no stone! He crawled from him without outside help and immediately climbed under the car to evaluate the scale of the disaster. Weaved plastic protection and dripping oil (viscous, transmission?) Did not promise anything good. But there is nothing to do, under small gas, Alexei and I talked towards the very greenhouse off-road of the highway, from which we recently set sail in search of adventure.


On the asphalt, the car began to throw under the gas from side to side to see the broken crankcase did not work out. Most likely, due to the destroyed support of the power unit, sags, lay on the cross member of the subframe and began to pull the drives of the wheels. In general, soon the devastated robot ended ... The hole in the box let the crew to the bottom. Stopped. It's time to activate the ZEV electrical mode. We are saved! Or not? By saving and recruiting the energy on occasion, supporting 40-50 km/h on the emergency and electric trustees, we met to civilization. And this, by the way, is about three kilometers along the serpentine! The charge was enough (this was later in characteristics I looked that the range on the battery is 4 kilometers). So if the fuel ends, there is a chance to get to the column within the quarter. Checked!



The engineers did not take care of protecting the alloy crankcase of the main transmission and differential of the electric motor. To split his pair of trifles. From the surface of the Earth to the lower point of the gearbox is slightly more than 180 mm (the plus of the blend is 160 mm). With the front power unit, the situation is no better, the engine and the robotic box are covered only with a plastic mudguard, which does not protect against mechanical influences

We were largely lucky twice on the checkpoint left a couple of engineers, with whom we talked the other day. He and Alexei and I took me at the ground 3008th to the airport. Such experiments are good when there is time. Then I felt it especially sharply, there were some kind of miserable half an hour before departure home, but still to saw and saw it before the airport. In general, there was a serious risk not to fly away today, in addition to all of us, a transplant in Paris was waiting for us ... The situation reminds the one that happened a year earlier during the Volkswagen Tiguan test. Only then in the river, just before the departure, we got stuck thanks to Lesha. 1: 1?

508 RXH is a solid, well -controlled car with an excellent interior and ergonomics. Capacity of 4.5 points. Economicity is phenomenal! On average, I spent a little less than 7 liters per 100 kilometers. And this is with a dynamics of 8.8 seconds to hundreds (9.5 with a devastated battery). Full -wheel drive, an anti -column body kit and an enlarged clearance make RXH suitable for operation on bad roads and light off -road. The possibilities of the drive on the crossed areas to match the geometric cross -country ability. And that's great. Only now expensive equipment is an engine, a robotic box and rear electric motor is not protected in any way. And this is a tangible minus. The only stupid stone, and the whole idea of \u200b\u200ba drain.

In Europe, Peugeot 508 RXH only goes on sale. The cost is 45,600 euros. For comparison, the usual SW with a 163-horsepower diesel and automatic transmission costs 38 100 euros. It is less economical, but in France it is legally established that when buying a hybrid, the state returns to you 2000 euros. If interested, you can pick up calculators and calculate how many years the hybrid will fight back. What for? Just because. The Russian prospects of the model, as well as the usual version with the station wagon, are more than foggy.

Technique


PEUGEOT 508 RXH divides the Hybrid4 drive with the Peugeot 3008 RXH and Citroen DS5. The sequential hybrid joint development of the PSA Peugeot Citroen, Bosch (the Germans designed and release the electromechanical part), Sanyo (battery) and many other satellite companies.
The rear wheels are given by an electric motor, which is powered by a traction battery.

The front wheels are driven by diesel engine 2.0 HDI, working with a six -speed robotic transmission. The engine is combined with an 8-acid generator, which is capable of, if necessary, to recharge the traction battery and nourish the traction electric motor.

1. A generator, united with the main program and differential.
2. The traction nickel-metallological battery Sanyo. The life life of the battery is equal to the life of the car. In numbers, this is 15 years with an annual run of not more than 15 thousand kilometers. Warranty of five years or 100,000 km of run.
3. PTMU unit (Power Train Management Unit), combining the converter and inverter. The cooling of power electronics and battery is air, it is carried out using fans.
4. Starter Generator.
5. A six -speed robotic gearbox BMP6 with a single -disk clutch.
6. The rear multi -link suspension collected on a steel subframe.
7. The front suspension, like 3008 RXH, MacPherson.



The rear multi -link suspension is a modular decision, it is the same for all hybrids of the concern. The module is assembled on a steel subframe into which the engineer-generator with the main program and differential are integrated (marked by green). The usual 508 has a completely different suspension suspension, but the body under the suspension and the Hybrid4 drive was minimal alteration. Pay attention to how shock absorbers with springs are littered
