• Tesla's CEO, Elon Musk, ordered his employees to stop submitting the nearly-finished 3 models to a critical test before leaving the factory in Fremont, California, according to a Internal document consulted by Business Insider
• This is what is called the test of brakes and roll, and it ensures that the car is properly aligned.
• An expert of the The industry told Business Insider that every automaker is doing this test to ensure quality and function.

Tesla CEO Elon Musk appears to have asked engineers at Tesla's factory in Fremont, in California, to remove a standard brake test, called braking test, tasks that model 3 cars must perform to move to the pro internal documents seen by Business Insider.

The test was apparently closed before 3 am on June 26, according to one person familiar with the case. It is unclear why this particular test was interrupted or for how long.

According to an industry expert, braking and roll testing is an essential part of the auto manufacturing process, which takes place during its final stages. The test ensures that the wheels of the car are perfectly aligned and checks the brakes and their function by taking the engine of the vehicle at certain revolutions per minute and observing how they react on the diagnostic machines.

In a statement, a Tesla representative, Dave Arnold, told Business Insider that every car undergoes "rigorous quality checks," including braking tests.

When asked if Musk himself gave the order to cancel the braking test, Arnold said, "I do not have it"

Here's what looks like the stage of the test of braking and roll in the internal production system of Tesla:

The far left column shows which stage the car h reached in the manufacturing process and which tasks should be performed there.

The two columns keys are those that are labeled "critical" and "blocking." According to a company employee, they demonstrate that it is apparently no longer necessary for the car to undergo this test before leaving this stage of the manufacturing process.

On the far right are all descriptions of the tasks to be performed. played at this station. However, since criticality and blocking are disabled, the car can leave the station, whether or not these tasks are performed, the employee said.

It is not known how many cars, if any, have left the station without doing this test.

Ron Harbor, a consultant at Oliver Wyman who founded and writes "The Harbor Report," a global manufacturing guide, told Business Insider that, after all that is installed in a car during the manufacturing process, a manufacturer "If you simply give up [the test] you could have a lot of quality problems with your customers," he said. "Every factory does that … It's all part of the car's finish."

Harbor told Business Insider that he did not know of any tests that could adequately replace the braking and testing test. rolling on a production line. ] "To be extremely clear, we drive * every * Model 3 on our test track to check for braking, torque, squealing and clinking," said Arnold in a statement. "There is no exception."

Musk has been for weeks in a race against the clock, trying to increase the production of the highly anticipated Model 3 of the company to 5,000 cars a week. On Monday, Tesla announced that it had "packed the factory" 5,000 cars the previous week, reaching its goal.

The Business Insider employee stated that the distinction between factory and gate is important. They said it meant the company was probably reaching its goal by finishing the cars that had already crossed the production line the week before but were selected for rework and then prepared for the safety of the company. Factory

It says: "A small number of cars are built over a week but stalled the following week, just like a small number of cars built the previous week. do not check until the following week, which is true for the last week of production, as it is always the case every week. "We publish our production figures in the same way that we have always done. "

Tesla also announced that it had completed 28,578 Model 3 in the second quarter, but Business Insider consulted internal documents showing that since last had planned to reach 36,020 models 3 in the second quarter. Tesla declined to comment on this figure

At that time, the automaker had manufactured fewer than 11,000 cars in June and just under 26,000 in the second quarter, putting it behind a plan of 36 020.
