As we all know, pure electric SUVs because of the chassis is arranged on a layer of power battery pack, so many people will have some questions in their minds: can pure electric SUVs really completely take over all the functions of traditional fuel SUV? Is it just a mimicking of the appearance of an SUV without similar off-road capabilities? On the other hand, most of the current pure electric SUVs consciously or unconsciously emphasize road performance, and there is very little mention of off-road capabilities, so let's unveil this mystery together today.
The two pure electric SUVs we evaluated this time can be said to be more representative, one is the Tesla Model Y with a considerable amount of market ownership, and the other is the equally popular Polar Fox Alpha T with all-terrain off-road capabilities. After all, it is to be light off-road testing, so both cars are all four-wheel drive models.
Before the official testing begins, let's take a look at the basic data of these two cars related to off-road. After measurement and calculation, the approach angle, departure angle and longitudinal passage angle of the Polar Fox Alpha T are about 19.90 degrees, 21.50 degrees and 7.80 degrees, respectively, and the approach angle, departure angle and longitudinal passage angle of Tesla Model Y are about 16.70 degrees, 19.90 degrees and 6.70 degrees respectively (the above data are manual measurements, and there will inevitably be errors, subject to the official published data). From the above data, it is easy to draw a preliminary conclusion: Tesla Model Y is still based on road performance, and off-road is indeed not very good at; while the Polar Fox Alpha T has the appearance characteristics of SUVs and the prerequisites for off-road capabilities.
This preliminary conclusion was quickly confirmed in the design of the two cars. As mentioned earlier, the Polar Fox Alpha T has three different representative road conditions of the off-road all-terrain mode of mud, sand and snow, while the Tesla Model Y only has two auxiliary functions: simple off-road assistance and get out of trouble.
Throughout the off-road field test, driving the Polar Fox Alpha T is still very confident and can basically pass all the test subjects. The Tesla Model Y is due to the smallest ground clearance, many subjects do not have the possibility of testing, a little regret. For example, in the test subject of the gutter, the Polar Fox Alpha T can easily pass, while the Tesla Model Y can only be simply meaning with a single-sided wheel.
However, in the test subject of simulating cross-axles, both vehicles have performed well, thanks to the innate advantages of electric vehicles, the adhesion wheels can get power immediately, so that they can easily get out of trouble by relying on strong torque.
In the course of this mild off-road test, we also found some "little Easter eggs". For example, the chassis suspension shock absorption performance of the Polar Fox Alpha T on this non-paved road is significantly better than that of the famous Tesla Model Y, worthy of Magna's master tuning hand, giving people a very high-grade filter texture.
Especially when the speed is slightly higher, the suspension of the Tesla Model Y is a bit stretched when dealing with this kind of unpaved road. And it may be that the Tesla Model Y does not have a special design of the roof beam, so in the process of off-roading, it will constantly hear the abnormal noise from the body.
In addition, in the polar fox Alpha T's car machine interface also appeared in the past only in the professional hardcore off-road vehicles will have a transparent chassis function, this function in the off-road process can give the driver a lot of help, or quite unexpected.
Through this day's mild off-road test, let's first say the final conclusion: that is, the pure electric SUV does have a certain off-road capability, and it already has the strength to take over all the functions of the traditional fuel SUV. Moreover, the inherent low center of gravity advantage of new energy models due to battery layout can bring better anti-roll ability; there is no engine air intake, so it has more advantages when wading; and the unique high torque output advantage of electric vehicles, these natural characteristics are more advantageous than traditional fuel vehicles in off-road.
In terms of the two pure electric SUV cars tested today, the all-terrain feature of the Polar Fox Alpha T does impress people in terms of off-road, and although the Tesla Model Y also has a four-wheel drive system, it is obviously not designed for off-road scenes, after all, an SUV with a tail diffuser, what can you expect it to do on the off-road field?
