"AutoLab 2021 Winter Endurance Test" has ended, and then it is time to announce the results one after another, about the overall results of the winter electric vehicle endurance test, my colleague has made a brief report to you in the previous tweet.
As the driver of the Volkswagen ID.4 CROZZ of the No. 9 car, I am also here to report my experience to you at the same time.
In this winter endurance test, we have prepared a total of 12 different types of pure electric vehicles, the test route from Shanghai to Hefei, the whole high-speed road conditions of more than 95% (considering safety, power output is limited when driving away from the high speed), driving until finally completely anchored.
Before departure, we set up a series of rules, such as weighing each occupant and using mineral water counterweight to ensure that each test vehicle maintains the same load, using ACC assisted driving throughout the whole process to eliminate the interference of different drivers' footwork, maintaining a unified air conditioning setting throughout the whole process and live broadcasting throughout the whole process, etc., in short, we strive to objectively and fairly measure the true endurance level of each pure electric vehicle.
How does volkswagen ID.4 CROZZ actually perform?
The specific version of the Volkswagen ID.4 CROZZ I drive is the 2021 first two-wheel drive version of the night, the official NEDC has a battery life of 550km, equipped with a rear permanent magnet synchronous motor, and the battery pack capacity is 84.8kWh.
▲Power at departure
Before departure, the SOC charge to 100%, full meter range of 391km, here to explain, Volkswagen ID. series of pure electric vehicles the meter range measurement method is based on the previous stage of driving mode dynamic presentation, in their actual driving process, its table mileage will gradually reveal the real data, and later tests also found that this is indeed the case.
This is also because I have been exposed to volkswagen ID. series products before, and I have experienced the authenticity of the endurance of this car, so I am actually more confident before I set off.
In the end, the actual situation is that after almost a full day of testing, volkswagen ID.4 CROZZ finally ran out of 478.64km performance, referring to the official NEDC endurance data of 550km, the actual endurance authenticity reached 87%, a very good result.
In the whole test process, in addition to the weather on the day is still good, we are driving at high speed in formation, coupled with the situation of two people with a load of about 130 kg, which is actually not very friendly to a pure electric vehicle, but during the entire test period, the Volkswagen ID.4 CROZZ meter showed the minimum energy consumption reached 15.4kWh/100 km, which is also a bit surprising for a compact pure electric SUV.
Even volkswagen ID.4 CROZZ in the SOC has reached 0% of the time still insist on driving about 20 kilometers, and although the instrument has a performance limitation prompt during the period, but there is no obvious motor power limitation, in 0% SOC in fact, we have been driving on the ground road, but the maximum speed during the period also reached 60km/h, acceleration is not affected at all. This setting is quite good, after all, if it is at high speed, it can greatly reduce the safety risk caused by low-speed driving due to power limitations.
In addition, since we recorded the apparent mileage and the actual mileage for every 5% drop in our entire SOC, and finally reviewed the recorded data after the breakdown, I also verified a very interesting situation again, that is, the longer it was driven, the more real the meter range of the Volkswagen ID. electric vehicle was.
For example, in the SOC 40% time, the table display endurance is 197km, at this time according to our trajectory records, the vehicle has driven 278km, that is to say, volkswagen ID.4 CROZZ will probably anchor at a position about 475km from the starting point, compared to the actual mileage after the final break-down, the error is only less than 4km, the table endurance is very real, tell you where to anchor, and eventually you will break down where.
In fact, to some extent, a large part of the reason for the endurance anxiety of pure electric vehicles is derived from the unreality of the pure electric vehicle table endurance, which obviously shows that it can still run 50km, and the result is 10km, and the performance of the table is still 30km, and this uncertainty about the anchoring situation is the most bald of the electric vehicle owner.
After all, the uncertainty and unreality of the table display endurance means that the future situation is uncontrollable, and the itinerary such as supplementary charging cannot be reasonably planned, especially for long-distance travel, and the authenticity of the table display of volkswagen ID.4 CROZZ can be said to greatly reduce the mileage anxiety of electric vehicle owners.
After finally completely breaking down, safely pull over and set up warning signs in the rear to wait for the rescue of the refill car, at this time the car machine system shows that it has been driving for more than 9 hours, and the system calculates the average energy consumption of 15.4kWh/100km. At this time, the vehicle doors and windows, lighting system, vehicle machine system and even the full speed domain assisted driving system can still be opened normally, but the permanent magnet synchronous motor located in the rear axle of the vehicle is no longer able to drive the car forward.
After a long test run, how about the Volkswagen ID.4?
Finally, this winter endurance test is actually not the first time I have come into contact with the Volkswagen ID. series of electric products, but it is really the first time that hundreds of kilometers of long journeys until the battery is completely exhausted and anchored. Long-distance driving is not an easy task, especially a long-distance test of running out of power, which not only tests the driver's patience but also tests physical strength.
But fortunately, I am probably one of the more relaxed drivers in the whole team, not only because of the sense of security brought by the real endurance, but also because of the comfort, intelligence and other additions of the whole car.
Because of a long-distance driving of 100 kilometers, for electric vehicles, it not only shows its true endurance, but also allows the driver to have an in-depth understanding of the dynamic driving experience, comfort, intelligence and so on of a vehicle.
In the whole process of high-speed driving, the Volkswagen ID.4 CROZZ impressed me most was the performance of the chassis, you can hardly feel that this is a mass of more than 2 tons, in the fuel car has been a large tonnage of electric models, Volkswagen ID.4 CROZZ chassis is solid, stable, but not the heaviness of most pure electric vehicle chassis.
In some slightly poorly paved roads, the chassis toughness of the Volkswagen ID.4 CROZZ will be significantly better than other vehicles, and in the entire long-distance driving process, the high-quality driving texture brought by the chassis performance can be said to ensure the comfort of driving and riding from the basis.
Since most of the mileage of the test was driven in the formation of the car in front, I was also impressed by the intelligent performance of the Volkswagen ID.4 CROZZ, which has an IQ. Drive L2+ Advanced Driver Assist, which supports full-speed domain adaptive cruise, at a speed of 0-160km/h, the system can automatically adjust the speed, distance and steering wheel, and almost no additional worry for me during the entire formation.
At the same time, because there are AR-HUDs and IDs. The overall interaction of the Light interactive light strip, the driver for the entire driving information is also almost instantaneously unaware of the grasp, especially can put the driving dynamic real-time feedback interactive ID. Light interactive light strip, the co-driver's little sister still can't stop praising.
And in the whole formation driving process, thanks to this, it can be said that it has reduced my pressure as a driver to a considerable extent, supplemented by the 12-way / heated / massage electric seat of the front row of the main co-pilot, etc. Comfort configuration, sitting in the Volkswagen ID.4 CROZZ car, in a trance, you will find that even if it is a long-distance mileage test that consumes physical strength, it seems that it is a lot of enjoyment at this moment.
