I am standing at the foot of Changbai Mountain, the temperature is -25, and I am about to drive this BYD Song L with snow tires to have an ice and snow endurance challenge.
The route of this ice and snow endurance challenge is 220 kilometers round trip, there are national roads, county roads, and urban roads, of course, more of them are actually on the ice and snow roads, and the cold weather and slippery roads are a great test for people and vehicles. This is a more extreme road condition, even the Northeast folks, there are few opportunities to drive on the ice and snow road, for an electric car, this kind of weather and road surface is double the crit.
From the perspective of users, the battery life under extreme cold, the handling experience under low adhesion, and even the stability of various configurations in the car also have reference significance at the car purchase level. Of course, ice and snow test drives are born with a sporty and handling atmosphere, and there are also full performance promotion opportunities for manufacturers, which is one of the reasons why Porsche, Mercedes-Benz, BMW and other traditional luxury car companies have insisted on holding ice and snow activities over the years.
And the model I drove this time is the BYD Song L 2024 662km Excellence type, and the official guide price is 22980,000 yuan. Unlike BYD Dynasty's previous models that focused on the family atmosphere, this Song L is labeled with "control", E platform 30. Yunnan-C chassis system, narrow front and wide rear tires, front double wishbone rear five-link suspension, etc., from these configurations, this Song L has enough confidence to provide stable handling ability on ice and snow roads.
But compared to these, the first thing I did when I got into the car was to raise the temperature of the air conditioner to 24 second gear hot air, and then turn on the seat heating and steering wheel heating, I have to say that these two configurations are really good things in the Northeast, Song L's wide temperature range and efficient heat pump system is heating up faster in the car (heat utilization rate increased by 20%, cooling and heat exchange efficiency increased by 10%), but my little potato operation down, the challenge for BYD Song L is greater.
In order to ensure the fairness of the challenge, the charging ports of all participating vehicles have been sealed, after all, this car was born on an 800V high-voltage platform, and the oil-cooled electric drive boost charging technology is blessed, which has achieved 100% compatibility and adaptation with public charging piles.
There is not much to say about the process of the endurance challenge, and it depends on which veteran driver's footwork is better. Before departure, the battery of our vehicle was fully charged to 98%, and the apparent range was 653 km, and the final result was that after the challenge of 218 km, the apparent range was 49%, and the remaining range was 327 km, with a range achievement rate of 668%, under the condition of -25 + ice and snow road + snow tires + 24 air conditioning heating, I think it is very, very good to be able to achieve such a battery life.
What surprised me even more was that the first place in the Ice and Snow Endurance Challenge was 7415% endurance achievement rate, it can be seen that BYD Song L in such a cold situation, can also run other brands of models at room temperature endurance level, the battery started BYD, in the current new energy environment, does show a sense of power to reduce the dimensionality.
Every winter comes, Porsche, Mercedes-Benz, BMW and other luxury brands will hold ice and snow test drive activities in the Northeast, after all, the ice and snow is a good stage for luxury brands to show their performance, but this year BYD Song L held in Changbai Mountain Ice and snow endurance challenge is more violent, in addition to showing their performance control, but also to ice and snow endurance challenge to show the advantages of battery life, we all know that the temperature in the Northeast is minus twenty or thirty degrees, which is indeed a great challenge for electric vehicles, Of course, this is inseparable from the deeply integrated eight-in-one electric powertrain carried by Song L, which not only reduces the loss of energy transmission, but also reduces the switching loss of the silicon carbide module it uses, so that the comprehensive working efficiency of Song L is as high as 90%.
And on the "driving ice and snow" part, Song L's sense of control also brings a high sense of friendliness, although it is equipped with snow tires, but the low adhesion of ice and snow roads will still bring a very high risk of "loss of control" to the vehicle, and Song L is equipped with narrow front and rear wide tires, maximizing the use of front and rear axle loads, so that driving can further explore the limit. The front narrow tires make the front of the car flexible and easy to operate, and the rear wide tires ensure grip, coupled with the strong control of the front double wishbone + rear five-link suspension on roll, so that I can face the situation of loss of control and rescue alternately on the ice and snow, Song L not only ensures the safety of emergency avoidance, but also brings me a sense of satisfaction after conquering success.
Of course, if you are dedicated to the pursuit of safe and comfortable driving, Song L's Yunlin-C intelligent damping body control system can also bring extremely high stability to the vehicle, and the electronically controlled shock absorber can actively adjust according to the road condition information collected by the sensor to achieve stepless adaptive change of damping. Different from what friends in the south imagined, in fact, the bumpy feeling of driving on ice and snow roads is very obvious, and Song L can maintain a stable body posture after the adaptive change of shock absorber damping.
On the one hand, BYD Song L has achieved excellent energy consumption performance in the endurance challenge in severe cold weather; On the other hand, the Song L's chassis tuning performance is also good enough. Although for the vast majority of users, the opportunity to drive on pure ice and snow roads can be said to be basically non-existent, even northern users are at most encountered in the backlog of ice and snow on the road, as long as you drive carefully, there will generally be no problems. But for Song L, the ice and snow road can still be conquered so far, and the driving experience of the conventional road is easier to boost the confidence of users.
