On May 21, Consumer Reports released a detailed summary on its Tesla Model 3 testing, focusing on the sedan’s poor braking performance.

Shortly after, Tesla CEO Elon Musk vowed the automaker would get a fix out within days and it was actually on schedule. Consumer Reports says braking distance has improved by almost 20 feet through the OTA update, which is really unheard of when it comes to the auto industry. “I’ve been at CR for 19 years and tested more than 1,000 cars,” said Jake Fisher, director of auto testing at Consumer Reports, “and I’ve never seen a car that could improve its track performance with an over-the-air update.”

So how was it done without having to install new brake rotors or brake pads? A Tesla spokeswoman said the automaker improved the software for the Model 3’s antilock braking system to adapt to variations in how the brakes might be used and to respond to different environmental conditions.

In new tests, Consumer Reports found the Model 3 stopped in 133 feet from 60 mph, an improvement of 19 feet. That new shorter distance is typical for a compact luxury car and helped improve the Model 3’s Overall Score so that it is recommended by Consumer Reports. The publication also noted that Tesla has begun to roll out some changes to address the car’s controls, with testers finding that the controls for the side-mirror and steering-wheel adjustment on the touchscreen now function differently.

Now, Musk did promise the Model 3’s braking performance would be best-in-class. Although the update did result in improvement, the results still aren’t class-leading, so don’t be surprised if another update is rolled out to further improve the Model 3’s braking performance.

But there you have it. We somehow managed to live in a world where cars can improve their braking performance with an OTA update, similar to what we receive on our smart devices.
