In the new column "True Wild Reality Test" opened by the Driving School, in the previous few issues, we tested the two city-biased SUVs of Lando FREE and Highlander, as well as the hottest extender "Daddy Car" Ideal ONE, but there has never been a real "off-road vehicle" entering the off-road field of the Tianfu International Circuit - the special venue of "True Field Test" to set a difficulty standard.
And this time, Tuda , which is also our camera teacher's favorite car , the 2020 automatic all-wheel drive flagship version , finally challenged the difficulty of this track as "a non-load-bearing off-road vehicle with girders". One question that may be a lot of people is, 2.5 naturally aspirated to reach in the off-road field, is the power enough to see?
And in my experience of participating in Tuda's national test drive in 2018, it will at least not be timid when facing such an off-road venue. Especially in terms of hardware structure, Tuda has a low-speed four-wheel drive that can amplify the torque, and with the rear axle differential lock and the electronic limit slip of the four-wheel drive system, the bottom line is very sufficient.
When the ignition starts, the silicone oil fan connected to the crankcase creates a "ground shake" momentum, like a "5.7 V8" Land Cruiser. This is not the end, the first plate can give you a "hard pie" feeling, the weight of the low-speed steering machine can make you wake up instantly, although it is not about "men's gym", but the left and right full of only 4 turns of the steering makes people feel crossed.
Or take you to a brief review of Tuda's "keyboard value": 2.5L natural suction power and the QR25 of the old X-Jun are exactly the same - the maximum power of 184 Ps and the maximum torque of 251Nm, but the two cars have different orientations in tuning. In addition, this Jetc Gatcore 7AT gearbox also has a head - it is also mounted on the million-level Infiniti QX80 (Tule).
Coming to the first project, ramps, for a non-carrier off-road vehicle, this kind of subject can be said to be not difficult at all, I kept Tuda in the rear-drive 2H mode, directly on the end of the matter.
On a slope of nearly 30 degrees, the 1835mm high and long-stroke suspension, coupled with a higher sitting posture, have a more exaggerated body feeling. The little partner who does not play off-road really thinks that he is going to "overturn", in fact, the performance of Tuda at this time is very stable, not only the rear wheel does not have any signs of slippage, but also the body does not have any abnormal noise.
We will not engage in the "open trunk on the slope" test this time, because for non-load-bearing off-road vehicles, the original body is not integrated with the suspension, the actual significance is not great, plus Tuda does not have an electric tailgate, and there will still be safety hazards when operating on the slope.
Then came the gravel pavement. Tuda uses a time-sharing four-wheel drive system, and at this time I used Tuda's 4H - high-speed four-wheel drive mode. I think that on the one hand, the use of 4H is to ensure the safety of off-road, after all, unexpected situations are always unexpected; on the other hand, hanging 4H makes the front and rear axles have driving force, which is also a kind of protection for tires, and the loss of tire scratching in the wild will not be small.
This non-loader off-road vehicle also has the advantage that its chassis is "placed" on the girder of the body, and there is a layer of physical isolation, such as the link between the entire suspension and suspension, which is located on the "H-type" girder. So, when you drive the Tuda on this intensity of unpaved pavement, you feel relatively comfortable, and there is no obvious sense of impact transmitted into the carriage. Even the shaking and vibration formed by the small fork shaft carry a sense of isolation.
Even so, carefully control the speed of the car on the bumpy road and patiently choose a route that avoids sharp rocks. The approach and departure angles of the Tuda are 32 degrees and 27 degrees, respectively, and the wheelbase is also 2850mm, which is the size of a medium-sized SUV.
There seems to be no pressure on the bumpy road section, but in fact, it is precisely because of the long-stroke suspension of the non-carrier body, while ensuring passability, it is easy to have a large shift in center of gravity due to back and forth compression, and the speed of the car is too fast there will be the risk of "kowtowing" scraping the chassis, which is especially bold and careful for off-road whites.
Next is the more challenging three humps, this time continue to hang on the 4H high-speed four-wheel drive mode, in the absence of low-speed torque amplification, if you did not open the way before or feel a little weak.
In fact, this seemingly weak chicken 2.5 naturally aspirated engine has a good initial explosive force, originally thought that the sensitive initial stage of the throttle is just to cover up the lack of torque, but the actual situation is that when going up the first slope, you only need to continue to stabilize the throttle at 2000rpm, you can go up relatively calmly.
When climbing the next 2nd and 3rd humps, there is no need to increase the throttle. As long as the self-priming engine torque matches the speed of the point, Tuda will appear more relaxed, of course, not easy.
One of the things I personally like is that Tuda's electronic all-wheel drive system has a limited sliding function, which automatically distributes the drive force to the adhesion tire. Compared with the "original off-road vehicle" of Jimney, Tuda is obviously much more humane and relatively more suitable for home use, and can ignore the differences in driver technology as much as possible to make off-road easier.
Letting Highlander break the sand and sink the sand "good Han Slope" can be regarded as a slope of truth to test whether a car is a "true off-road vehicle". After passing the first slope without alarm, hang up the 4L low-speed four-wheel drive, pull the speed to about 4000 rpm, and the torque amplification of the low-speed four-wheel drive allows Tuda to have no lack of power during the climbing process.
When it is close to the top of the second slope, it is a smooth surface without dust, and it can be clearly felt that Tuda's electronic limit slip is in play - the limit slip function is timely to prevent the loss of power, and at this time, it still does not feel that the power is pulling the hind legs.
Coming to the third slope with the most difficulty, locking the rear axle differential in the 4L low-speed four-wheel drive state, the ESP light is turned off and anti-slip, and now it is the strongest off-road state of Tuda. After some route selection, Tuda slipped in the place where the three slopes had crossed axles, at which time the throttle opening was increased, and the original AT tire struggled to maintain traction, and the vehicle quickly regained grip.
In fact, after hanging up the differential lock, there is really nothing to worry about the passability of The Wayda, and I think the only deficiency in the equipment is the original at-road performance of the AT tire.
Driver's Summary:
After today's "True Field Measurement", we found that Tuda's passing ability belongs to the mainstream level of hardcore SUVs, the electronic limit slip intervention is very rapid, and after the rear differential is locked, the performance of the rescue has been significantly improved.
If it is not some extreme subjects, it will not pose a threat to the original AT tire. The 2.5L naturally aspirated engine is not a short board in the off-road scene dominated by low speed. Of course, the throttle opening will be relatively large during daily driving, and torque is obtained by pulling up the speed. The only thing to note is that in highland areas like Western Sichuan, the acceleration distance of Tuda's overtaking is sufficient.
Therefore, I think that the core competitiveness of Tuda is not only the passing performance of the hard-core SUV, but also the stability - the maturity of the powertrain system, including the 7AT gearbox of Gatco, is quite reliable. About 250,000 yuan can have the non-load-bearing girder equipped with hardcore off-road vehicles, rear integral axle suspension, rear axle differential lock, and electronic limited slip function, in this price point of medium and large SUV, Tuda has few opponents.
