If winter comes, and the circle of friends to locate automotive media’s “way north” of the season. Mohe, Hailar, Heihe … as more and more ice each car brands test drive program, these Chinese “northernmost” names have gradually been familiar to fans, but snow everywhere these small town in the North, but also integrates natural Test drive the required subjects natural track. Here’s driving experience and other people believe can make a relish for a long time, such as Chevrolet and this time we participate in the joint launch of the Discovery Channel DC24 hour test drive …
first 24 hours: at the factory inside the proving ground “engaged in things.”
– when we talk about snow test when driving, what are we talking about?
“do something?” When you see the screen in front of snow-draft test drive wheels are raised snowing, you might think we are in much work, seems to limit the exercise of these snow and ice your daily driving and driving simply does not matter. In actual fact, as most manufacturers before the launch of the new car will be almost ice (Arctic) test, to ensure that a car can in a complex road conditions and low to forty degrees below zero three car environment to maintain a reasonable reliability, especially part of the safety-related control, in fact, is very necessary.
For perhaps inappropriate example: although most say the car airbags to scrap that day are not necessarily have the opportunity to detonate, but if the manufacturers with Jane probably still make a lot of people took it the keyboard. So in fact, this event is mainly to show us the Chevrolet SUV models, under the snow and ice environment “security control”, and in this context can carry more possible and fun.
Since this is a security-oriented, and that a large enough buffer space is a necessary prerequisite. Specifically how much? You can search under “wau Lake Reservoir,” this time we test track is on the wau lake frozen lake, including ice and snow of dozens of test areas and subjects are specifically listed as a former car factory car testing the ice to create a professional venue, every winter there are a lot of engineers and test drivers withThe new car covered with camouflage here.
It is precisely because these cars are kept in secret camouflage, so here is generally strictly forbidden to take pictures of. However, as a part of this experience activities, it said that we are the first to be allowed media within the test site of the shooting. A rare opportunity, then let me bring you in here to find out.
In the two-day test, we are most of the time driving a Chevrolet four-wheel drive version of the 550T’s exploration sector. Domestic product in the current sequence in the sale of Chevrolet, this is equipped with four-wheel drive 2.0T plus 9AT midsize SUV should be regarded as a veteran. For safety and better performance, but also for the organizers test drive through its good replacement Jia PX Winter500 brand snow tires (with single guide patterns and fine snow tire tread sipes necessary). In addition, other vehicles are equipped with this state maintained the original.
into the interior of the field test, a vast lake entire snow-covered, with the introduction of a large equipment skiing routes and compacted snow surface, and then combined with high natural snow slopes on both sides launched almost 30cm of snow walls, is our today’s test drive of the environment.
and, like all venues test drive, all of the first to experience such as a linear accelerator, a class of conventional emergency braking subject combination, just bring snow surface becomes low adhesion so that these subjects require a longer time and distance.
In the process of doing the full linear acceleration from a standstill, the starting moment it is possible to break the tires grip the snow surface, so the exploration sector’s electronic stability system to make the engine speed is close to 2000rpm “ramp-up” period, until the vehicle speed exceeds added after about 40km / h grip gradually stabilized, so that the engine rotational speed limit and then release the quick climb. In everyday driving, such a design orientation can try to ensure that the vehicle is in a more controlled state, to enhance stability in hard acceleration.
Compared to a straightLine acceleration and braking, should be more fun to drive character count, slalom and snow ring the subject of such a curve. In particular, we experience the venue two snake-like compacted snow surface of pure ice and different situations Slalom.
in the snow around the pile, the four-wheel drive system, electronic stability system and allows snow tires facelift probe bound by this holding good controllability, body roll when the shuttle also between piles is preferably suppressed, so that the driver only needs to appropriately control the speed and reduce the amplitude of the direction of play, and then the pile into the process to leave a certain amount in advance, the driver can do ordinary faster rate complete snow slalom.
In contrast, the ice around the pile becomes much more difficult, because we did not test drive studded tires fitted, so you have to put the ice in the speed control at a lower level (if snow 40 to 50km / h when the tracking Slalom have substantial nature, then you probably only on the ice this figure down to 20km / h or less).
After the ice
/ snow large annulus subjects also confirms the great difference of snow and ice. In a large diameter circular area, the outer ring is slopes, the inner surface of the ice. It is important to control the speed at the time of the ice around the ring, started to break when the speed limit a little, you can also control the car back on track by delicate throttle; but if the speed exceeds the limit too much on the basic can only pray. In comparison it would be much easier to travel along the outer ring road of snow, at a speed of about 50km / h, driving feel and dry almost no difference.
As the speed gradually enhanced, when the vehicle speed exceeds approximately 60km / h, the vehicle can feel you start out with a tendency to slip, then at this time if the lifting speed 10-20km / h, the vehicle tracking sex will significantly further reduced. Here I want to commend the proper balance of this sector’s exploration: when the speed increase, tire grip gradually insufficient to support the required centripetal force around the circle, this exploration industry who will show a “four wheels to a round outer sliding synchronous “state, compared to a simple flick of the pushing head or, in this state for the driver to better control the travel route and vehicle dynamics are significant benefits, and in this process, four-wheel drive , electronic stability systems, tires and suspension tuning performance have contributed.
and the like rings, snow surface around the character is also quite fun subjects. In this process, if you can feel better weight transfer and supplemented with appropriate throttle and directional control, you can make the operation of the four-wheel drift, snowing raised in the figure below.
The first 24-hour test drive to complete a match as snow track ending exploration industry, competition cars and vehicles used in practice They are different, and displacement are replaced by smaller stature creator community. But do not think that the record industry 1.5T 165 horsepower contrast between geological exploration industry’s 260-horsepower 2.0T will become less fun, if you really from the perspective of competition, lighter body weight means the centripetal force needed to bend to smaller in this multi-turn on the track in fact, we have the opportunity to get better than that exploration industry practice when those results. Provided that …
with the proviso that not off the track. We first leg of the relay race teammates rushed snow wall of the edge of the track. The original day daytime sun drying is gradually melting the snow in front of the last two combined curved, is cryogenically frozen into ice at night, the next day was covered by a thin layer of snow formed a “dark ice”, so then snow the speed into the corner of the naturally sorry. Visible, careful driving is always right.
are summarized below: a probe bounded by Chevrolet as such good performance and a four-wheel drive SUV snow tires, coupled with the road conditions to predict in advance, the holding operation and the amount of the reasonable control of the speed and range of motion in advance, it should be regarded as opponents of the subjects completed the test drive. Further, try not to roll dark ice.
The second 24 hours: through woodland + vs. Wild
– Do not light drinking (Piao) Wine (yi ), you eat (chuan) dishes (yue) ah
snow drift and of course fun game, but for the purpose of “close to real traffic” or not to drink. Therefore, according to the activity schedule, the day before the test subjectsDriving is to let everyone can quickly familiar with snow and ice driving skills to cope with the next day through the woodland. But when you really put the car into an uninhabited forest covered in snow, the actual situation test venue compacted snow surface smoothness is much more complicated than that.
Fortunately, this exploration sector’s good performance in the two dozen kilometers of driving through the forest, following the path of the coach to lead, exploration sector in case it is full of people and equipment 5, still it does not require much driving skills to complete the crossing. Some even in the face various obstacles, SUV inherently has better ground clearance, approach angle and departure angle, but also make your driving more calmly.
Although this across the line is not difficult, but there is no snow, the track wall means that if reckless driving will still exist a certain risk. Even back to the road surface, it may appear at any time pedestrians, bicycles and even small animals crossing the road, and suddenly snow extending from the shoulder, and in these cases, the exploration sector’s four-wheel drive system and dynamic performance can also bring you to feel more at ease, and this is almost every new car manufacturers have carried out dozens of one mind on one million kilometers of testing.
crossing the process, as the Chevrolet organizers also invited together with Discovery large coffee field survival from New Zealand Josh James, wild fire, build a shelter, set hunting trap, making snow shoes and other project activities also make the experience richer. “Paper come Zhongjue,” if you can Soso DC 24 Xiaoshi Chevrolet SUV driving training camp experience for those interested in a test drive and experience by appointment.
In the end, there are two things I would like to remind you this day: one through the process if the car stuck in the snow vehicles, try not to expect accelerator plus “scratch out”, since it might give yourself a bigger hole dug, try to reverse and then open up a route plan. Second, do not believe in the circle of friends and the group of those “snow day close ESP” of “Tips” in the absence ofBefore reaching the level of deep snow vehicles, electronic stability system, the new model is still able to provide more protection for you.
About Heihe, there are several interesting thing I want to share with you.
First, if you think only understand the “ice thousands of miles” in Heihe, you’re wrong. Admittedly, we arrived early in Heihe, the temperature actually reached’s creepy sounds of minus 22 degrees to minus 34 degrees (like our test sites in the somatosensory temperature of the ice surface may be lower 3-5 degrees). But you might not think that a single day in June, the city’s temperature can also be “up to” 32 degrees to 17 degrees, so if you want to feel the snow and ice in the spring and summer, we will have then north.
See you.
