What is the 0-100km/h acceleration time of the Tesla Model 3?

The domestically produced Model 3 has a measured 0-100km/h acceleration time of 5.6 seconds. Below is some relevant information about the Model 3: 1. Introduction: The Tesla Model 3 is a new product in the Tesla Model X series, officially launched in the United States on April 1, 2016, at 11:30 AM Beijing Time, with a base price of $35,000. Before opening online reservations, the Model 3 had already received over 115,000 orders through in-store queue reservations alone. 2. Features: The Model 3 does not use an aluminum body, so the body size is reduced by 20% to offset the impact of increased weight on range. The Model 3 is expected to have a range of approximately 320 kilometers. It eliminates the flashy but impractical falcon-wing doors and removes the 3-second 0-60 mph launch acceleration; the autopilot feature may also be removed.

What Color of Engine Oil Indicates It Needs to Be Changed?

Here are the methods to determine when engine oil needs to be changed based on its color: 1. Freshly added engine oil is golden yellow in color. The detergents and dispersants typically added to the oil help clean off the carbon deposits and gum films adhering to the pistons, dispersing them in the oil to reduce engine deposits. 2. From this, we can understand why lubricating oil turns black after being used for a period of time. However, the oil at this stage hasn't necessarily deteriorated. To determine whether the lubricating oil has deteriorated or needs to be changed, you can assess the oil's viscosity. 3. The method involves placing a drop of oil on a test paper and observing the spread. If the edges of the spread are not clear, the oil is still usable. If a ring forms, the oil is still acceptable. If the ring is very distinct and the spread is minimal, it indicates that the oil needs to be changed.
