Consumer Reports raises concerns over Tesla Model 3 braking, functionality

According to a different Musk tweet (it's hard to keep track of all these), the problem is likely due to the calibration algorithm in its antilock braking system. But the Model 3 fell a bit short of getting the magazine's approval because "testers found flaws-big flaws-such as long stopping distances in our emergency braking test and difficult-to-use controls".

Having made headlines recently attending the Met Gala with new partner, SpaceX CEO/Tesla co-founder Elon Musk, Grimes has now defended her boyfriend after fans tweeted their concerns. Musk, however, has assured that any fixes required for braking will not be at the cost of the consumer.

However, Musk did not note that when CR's testing revealed highly inconsistent braking distances - "far worse than any contemporary auto we've tested" - the magazine obtained a second Model 3 to test, and the results were the same. Now, Musk has tweeted that those reserving the least expensive Model 3 could see their cars as soon as September.

Taken one way, it's a sign Tesla is working through the early production struggles of the Model 3 and is ready to start offering more diverse options, much like it does with the Model S or X. But Tesla also needs to sell these more expensive Model 3s to grow its revenue at a time when the company is spending more money than ever. But after some negative reviews of its braking performance, Tesla CEO Elon Musk has vowed free improvements on the Model 3's braking performance for all current and future owners. He asked Consumer Reports to retest the Model 3 with a newer model with "improved ride comfort, lower wind noise & many other small improvements". Tesla responded to the Consumer Reports review by saying its own tests revealed a 60-to-0 miles per hour stopping distance of 133 feet, shorter than Consumer Reports' average result of 152 feet. Drivers must use it to do everything from adjusting mirrors to changing air-conditioning flow, rather than the typical physical buttons inside most cars.

Having said that shale oil production in the USA has constraints in the form of lack of piping infrastructure and skilled labour. Between 2014 and 2017, oil market "rebalancing" meant restricting production, stimulating demand and cutting excess inventories.

In mass-market mid-sized cars, vehicles recommended by Consumer Reports account for over 80 per cent of the category's sales volume, Barclays analyst Brian Johnson wrote in a client note.

Addressing Musk's remarks, Jake Fisher of CR told The Verge that the company is "pleased that Tesla is taking our braking test results seriously".

'If so, we will address this at our expense.

"It is important not to be too harsh on Tesla, as other vehicles have had their share of safety and technical issues", he said.
