Jeep Grand Cherokee test drive since 2010 SUV

Jeep Grand Cherokee received a new engine from Italians

Chrysler refuses German engines in favor of Italian. The new diesel for Jeep Grand Cherokee is more powerful, more economical and environmentally friendly than the previous one ... When this happened to me in Rome for the first time, I laughed and thought an accident.


But recently I had to fly to Milan at the invitation of Chrysler and everything was repeated. I am about the fact that everything, literally everything that is done in Italy, is either already broken, or will break in the near future. Already at the entrance to the hotel I was met with broken automatic doors. I have never seen in my life that Seraton had something similar in at least one country in the world. But this is nonsense. The air conditioner did not work in the room. The radio did not work in the multimedia complex.


With pneumatic suspension, the road clearance reaches 270 mm, and you can climb even further

The liquid crystal panel hung crookedly on the wall, that is, it did not skew it from the wind, it was initially tightly fixed askance! When I went to breakfast the next day, I saw a broken elevator, he looked at me with half -open jammed doors. There was a completely broken coffee machine in the restaurant, the waitress repair it every five minutes, but it helped for a short while. It did not steam anyone. Italy! It should be so here, since even the bus driver in profile looks like Caesar, and such people are not up to the smallest detail. They think largely.

The roof changes the supplier
In what vein is it worth considering a new three -liter turbodiesel for Jeep Grand Cherokee? (By the way, they will begin to sell it at the end of this year.) He develops the maximum power of 241 liters. With. And it gives out a torque of 550 Nm. Thus, in comparison with the previous engine, the power of the new is increased by 10%, and torque by 8%. At the same time, the fuel consumption, as the manufacturer claims, in the mixed cycle is 8.2 liters per hundred, which is 19% less than that of the predecessor.

Italians are proud of the latest injection system (with a pressure of 1800 bar), which was developed and patented by Fiat Powertrain. Multijet II technology is also boasted using a special electromagnetic valve that allows the nozzle to carry out up to eight fuel injections per cycle. This guarantees a decrease in fuel consumption and a decrease in harmful emissions into the atmosphere by about 2% compared to traditional nozzle, as well as a sharp decrease in noise level.


But we understand that this is all PR. In fact, after Chrysler changed the German roof to Italian, the latter decided to plant Yankees on its own engines. Like, why will they take Daimler diesel engines if Fiat has their own? However, another option is not excluded: so that Grand Cherokee could not compete with the brother in the Mercedes-Benz ml aggregate base, the Germans, after the divorce of companies, simply did not give their diesel engines for the Jeep brand.


The hooks remained in place this is the main thing!
 
Not Marlene Dietrich is no longer
I traveled a little to the Jeep Grand Cherokee with a new diesel in the Milan region and found that he was pretty good. Acceleration is peppy, there are more than enough Newton-meters. On off -road, it pulls well on decent lifts with a control stop in the middle of the hill. It is difficult to compare it in absentia with the German predecessor, but according to subjective sensations, he now sings as Luciano Pavarotti, and not as Marlene Dietrich.


If it were not for the tree beloved by the Americans in the decoration, the interior would look exclusively. And so you can argue about tastes ...

Let us return to the quality of Italian products. Do you know what all automobile journalists talked about on the trip? Do you think about the reliability of the Italian novelty? Nope. They asked when Chrysler will finally throw a German multifunctional steering wheel switch to a landfill, which has been enraging all the testers for several years. For a journalist, the change of Daimler diesel is just the first step towards getting rid of the German inheritance in the form of a very misunderstanding. Maybe so it is necessary? In any case, Italian turbodiesels with a working volume of 2.8 liters on Cherokee/Liberty have been working for a long time and do not ask pasta.




Caution, technical details
In fact, the installation of the Italian diesel diesel engine under the hood Jeep is by no means a sensation. Jeep put the VM Motori diesel engine (Vittirio Martorelli), which has become a Detroit Diesel unit since 1995 for a long time. 3.1 liter in a line five-cylinder engine developed 150 liters. With. at 4000 rpm and a moment at 373 Nm at 2000 rpm. The German CRD 2.7 L manufactured by Mercedes-Benz in 2002, has already developed 163 liters. With. At 4000 rpm, and the moment at 400 nm at 1800 rpm was also a five -cylinder in order. The Italian Diesel did not occur to the revolution to his native nest for the European modification of Grand Cherokee. In their homeland, these machines with diesel engines are not sold. However, in the design, Jeep received a completely new power unit. Now it has six cylinders located V-shaped. Having a working volume of 3.0 liters, the engine develops the maximum power of 241 liters. With. At 4000 rpm and torque 550 nm in the range of 18002800 rpm. The design of the engine is compact and small. Dimensional dimensions: length 695 mm, width 729 mm, height 697.5 mm. The mass of a completely equipped engine is 230 kg. Along with the high rigidity of the block carder, the quiet work is provided by a durable oil crankcase made of aluminum alloy. The lower pallet was reinforced taking into account the operation of the car in off -road conditions.
