H-DOG is named Haval’s ＂Second Generation Big Dog＂. Let’s look at the differences between the first generation and the second generation.

Harvard unveiled a new car called "H-DOG" at the beginning of the year, and its Chinese name was not announced before.

Because the dog’s image is "cute", some netizens call it "Han Han Dog".

However, Haval Automobile finally positioned its Chinese name as "the second generation big dog", which will be the first new energy SUV； in the category of Haval dogs; However, the car is not a pure electric vehicle, but a 2DHT plug-in hybrid platform developed by Great Wall Motor. If there is a "second generation", there is naturally a first generation, that is, the first generation. Whether the second generation is "evolution" or "offspring" is only for you to feel; Let’s take a look at the design of the two cars first, and compare them one by one from different angles.

Front 100%:

The most handsome angle:

Tail, focusing on taillights:

Aesthetic opinions are different. Personally, I don’t like the second generation big dogs, because I feel that their eyebrows are too exaggerated, and the taillights are too similar to BJ20 of BAIC. The first generation of big dogs looks more eye-catching, and the square body is simple and clear, and it does not lose its tough temperament. I feel that the first generation of big dogs is like "German shepherd", but the second generation of big dogs is like a bully.

However, the interior of the second-generation big dog is quite eye-catching. The LCD dashboard with a frame looks good, the screen of the suspension car is large enough, and the sense of technology is still quite strong. The shift lever is still in good shape, and it looks quite tough. The width of the center console is also good. After all, the body size has reached 4705*1908*1780 mm, and the wheelbase is also 2810 mm.

The off-road capability of this car is unknown for the time being, and the existing parameters are as follows.

• Approach angle 24.
• Departure angle 30
• Longitudinal passing angle is 19.
• Minimum ground clearance is 200mm.

The approach angle of the tank 300 is 33, the departure angle is 34, the passing angle is 23, and the minimum ground clearance is 224 mm and the highest is close to 250 mm..

This shows that the passing capacity is not very strong, but this car is not an off-road vehicle, and the load-bearing body it uses is only suitable for outdoor light off-road driving; The functional positioning is the same as that of the original big dog, but the plug-in hybrid version should not talk about off-road capability-because it should use the same front-drive plug-in platform, so don’t talk about off-road without four-wheel drive, at the very least, it is the rear drive plus rear axle differential lock to see the threshold of off-road.

However, it has not been confirmed whether the plug-in hybrid version of the second generation big dog has a four-wheel drive option. In the four-wheel drive car using this system, the lowest level is Wei brand latte at present; If the second generation big dog is also used, then the plug-in four-wheel drive version of this car can also be off-road.

The second generation of big dogs will also have fuel versions, and it is possible to launch 1.5T and 2.0T fuel versions at the same time; Among them, it is possible to use the four-wheel drive system for the 2.0T version. Because of its large size, it is really difficult to build a four-wheel drive with a power reserve of 1.5T. The 2.0T engine should be a 4N20 Miller cycle engine, because both the Haval brand H6 and the first generation of big dogs chose it, and this engine is more fuel-efficient than the 4C20B-2.0T Otto cycle engine.

The standard used by the first generation of big dogs is 155 kW/325 N m (1500 ~ 4000 rpm). It is estimated that the standard of the second generation of big dogs is 175 kW, and the maximum torque has not been confirmed. The transmission should also be a horizontal wet powershift, so it is unlikely to use the ninth gear.

Finally, look at the "differential lock" of the first generation of big dogs. The reason why the evaluation of the first generation of big dogs is high is that the four-wheel drive version of the car has a differential lock.

After the differential lock locks the differential function of the differential, the left and right rear wheels can only run at the same torque and speed, which can prevent one side wheel from slipping and the opposite side wheel from losing power; At this time, as long as one wheel has enough grip, the vehicle can get out of trouble stably.

Therefore, the first generation of big dogs can be regarded as light off-road vehicles, and without differential locks, they can only be regarded as ordinary four-wheel drive SUVs; If the second generation of big dogs also have differential locks, their off-road ability will not be worse than that of the first generation, and vice versa. At present, there is no car with differential lock on the rear axle in its plug-in hybrid version of series production cars. I don’t know what will happen to the second generation of big dogs, so we will wait and see.
