What about the Chevy Explorer? What are the advantages and disadvantages of engine and gearbox?

1, transmission ratio setting

At present, there are four brands equipped with 9-speed automatic transmission in the domestic market, namely Land Rover, Jeep, Honda and Mercedes-Benz. Among them, the first three brands all adopt 9HP gearbox from ZF, Germany, which is suitable for horizontal platforms, while Mercedes-Benz adopts its own 9G-Tronic automatic gearbox, which is suitable for vertical platforms. So what can be found by comparing these three gearboxes horizontally?

Comparing two 9-speed automatic gearboxes with horizontal platforms, it can be found that compared with ZF's crazy setting of four overdrive gears, the general 9-speed automatic gearbox only has two overdrive gears, which is more to reduce the gear difference between the front gears to ensure the smoothness of the vehicle when shifting gears, while ZF's design may be more to ensure the fuel economy during high-speed cruising. Compared with the 8-speed automatic gearbox currently used in the vertical platform of GM, the 9-speed automatic gearbox has a smaller gear gap, which makes the gear shifting smoother and can work in the best gear regardless of the engine speed or speed. At the same time, the new 9-speed automatic transmission also provides a start-stop function, which helps to reduce fuel consumption.

2. Offset adjustment

The shift control module selects the shift timing by receiving information from the brake pedal, vehicle acceleration, throttle position, slope and whether the trailer is connected. At the same time, 9AT has the function of automatic gradient braking. When taxiing or braking downhill, it will choose a lower gear to maintain the required speed, and use engine braking to prevent unnecessary acceleration, thus reducing the use of braking when downhill.

3. Active gearbox oil management system

The hydraulic system of GM's new 9-speed automatic gearbox adopts electronic control, which can provide the required pressure and the volume of gearbox oil at various working temperatures, thus achieving the best lubrication and cooling effect. The side cover of the valve body plays the role of an internal expansion tank, which stores excess gearbox oil when it is not needed, and sends the gearbox oil to the oil pan through pressure when the demand increases. In addition, the gearbox oil used in 9AT gearbox does not need to be replaced under normal driving conditions, which provides convenience for later use and maintenance.

Second, the engine.

When 1 and the engine speed is between 1200 and 1400, it is obvious that the muffler has * * * vibration noise. In particular, it is normal to go uphill to find a 4S shop to inform, and it is said that Buick Angkewei, who is on the same platform as the explorer, can't solve this problem. You must have a good test drive when buying a car.

2. Explorer RS will be equipped with 1.5T overhead direct injection turbine engine and 2.0T twin scroll direct injection turbine engine, in which the maximum power of 2.0T engine is191kw (260ps)/5500rpm and the peak torque is 353Nm/2000-5300rpm.

3. This 2.0T engine has sufficient power, a steady stream of strong torque output, which is vigorous and direct. Even at high engine speed, it will not be hoarse. Power output seems to be hidden under your feet all the time. Just step on the accelerator and the power you want will come as scheduled.

: Appearance parameters

As a medium-sized SUV, the domestic Explorer has a body size of 4652 *1843 *1661mm and a wheelbase of 2725mm, which is slightly smaller than that of Buick Angkewei. The new car adopts Chevrolet's latest family-style front face, and the middle net is decorated with a large number of chrome trim strips, with LED headlights and LED daytime running lights, which is fashionable as a whole. It is understood that the new car taillights will also use LED light sources.

Internal parameters

From the official map released this time, we can see that the new car will adopt Chevrolet's latest family-style embracing design, and the central control, steering wheel and instruments are basically the same as its new models. However, this car still has some unique designs in details. For example, the air outlet of the central air conditioner has more chrome decoration, and the front panel of the co-pilot has a more three-dimensional effect.

Vehicle configuration

In terms of configuration, the car will be equipped with a panoramic sunroof, an 8-inch LCD screen, and the tenth generation OnStar in-vehicle interconnection system.

Vehicle power

In terms of power, domestic explorers will be equipped with 1.5T and 2.0T turbocharged gasoline engines. The maximum power of 1.5T engine is 127kW, and the maximum torque is 275nm, matching the 6-speed automatic gearbox. The maximum power of 2.0T engine is 188kW, and the maximum torque is 352nm, matching the 9-speed automatic gearbox.
