How is the wear of the ONE at 50,000 kilometers?

Before I knew it, my Ideal ONE had already driven over 50,000 kilometers. Luckily, there was a free inspection event for car owners in April. As I was planning a long-distance trip this month, I spent a morning carefully inspecting my Ideal ONE at the authorized maintenance and repair center for sheet metal and paint located on Fanggong Road in Jiaxing.

Next, I will use pictures to document some personal projects that I am interested in and share them with everyone.

Tires

I had tested them before when the car had driven 40,000 kilometers. This time, I first tested a new tire and found that the depth at the replacement mark was 7.4mm, while the old tire, which had already driven 50,000 kilometers, had a depth of only 5.3mm at the same position.

This means that the tires wore down by about 2.1 mm² over 50,000 kilometers, and if this proportion is used to calculate it, this set of tires can still run for 100,000 kilometers, which is terrifying. If the wear-resistant coefficient of the inner layer is slightly lower, it should be no problem to run another 50,000 kilometers.

It seems that this set of Michelin Silent tires with a high wear-resistant index of 440 can accompany me for more than 100,000 kilometers. What a bargain, what a bargain!

Braking System

I first checked the status of the brake pads; the condition of the brake pads on all four wheels was more or less the same.

After driving for 50,000 kilometers, the maximum wear of the brake pads on my Ideal ONE was 2.2mm, and there is still at least a 4mm safety wear thickness. By this calculation, these brake pads can still be used normally for 80,000 kilometers. Thus, the total mileage for the brake pads can be as high as 130,000 kilometers.

I already knew that the kinetic energy recovery system of electric vehicles could greatly reduce the wear of the brake pads. After this test, I have a deeper understanding of it. It seems that the manufacturers of brake pads have a hard time.

After removing the tires and looking at the pictures of the brake rotors, all four were shiny and smooth to the touch. I didn’t want to test them, but the manager of the sheet metal and paint center, Mr. Wang, suggested that I give it a try.

From the data, it can be seen that there is only about 0.2mm of wear, and the old manager, Mr. Wang, said that it seems that I will never need to consider replacing these brake rotors. They should be no problem to run for 200,000 to 300,000 kilometers.

Inspection of various fluid levels

Here, I found that the Ideal ONE has three cooling fluids: the range extender cooling fluid, the battery cooling fluid, and the motor cooling fluid.Translate the following Markdown Chinese text to English Markdown text in a professional manner, retaining HTML tags inside Markdown, and only outputting the results.

Primarily because the temperature control requirements are different. For example, the temperature of the range extender coolant is controlled between 90℃-95℃, the battery coolant is generally controlled at about 25℃, and the motor coolant is generally controlled at about 60℃.

The staff took samples of the coolants and performed freeze point tests and water content tests on the brake fluid samples. All indicators are within the normal range.

It has been 7500 kilometers since the last range extender maintenance, so let's also check the condition of the oil in the range extender. The oil level remained in the upper-middle position of the dipstick, and there was basically no "burned oil" situation.

## Chassis Parts Inspection

During the entire inspection process, the staff also checked some rubber parts and sealing mechanisms on the chassis.

## Battery Inspection

## Tire Pressure and Torque

Finally, let's add the standard tire pressure and standard tightening torque for Ideal ONE tires.

Summary

This free inspection during my long-distance trip made me feel more secure, and helped me to understand the wear and tear of this 50,000 kilometer Ideale ONE. By the way, the inspection did not include the air conditioning system maintenance. I hope to add the inspection and maintenance item of the air conditioning system before the arrival of high temperature season.

The life-long quality guarantee and the PLUS pick-up and delivery service of this Ideale ONE make me feel very relieved for the later maintenance.
