“We don’t want to set the expectation that you can basically pay no attention to what the vehicle is doing”, Musk said in a recent earnings call. Tesla was agile from the beginning with the launch of the Roadster model, which tried to create a global supply chain like a typical auto company, but that was not the right choice for it. The automotive brand has begun standardizing its production practices by adding capacity for the Model S sedan and the upcoming Model X. And several publications with a well-established reputation for credibility in performance numbers have already managed to meet Tesla’s claimed 3.1-second 0-60 miles per hour time.

On the car’s brochures, the P85D can sprint to 60mph from standstill in just 3.17 seconds, but this is provided that the driver activates the Insane Mode. Offering a free and fast charging network and then chastising owners who use it doesn’t seem like a good business strategy.

According to a report by Autoblog, the latest iteration of Tesla’s Autopilot feature (version 7.0) has been rolled out to a select number of Model S beta testers.

“Tesla promises the new “Ludicrous” mode will lower that to 2.8 seconds, but based on our testing, we’re not convinced”, the report notes.

This is the same vehicle , by the way, that staffers were locked out of due to a failure of the Tesla’s retractable door handles.

See the video below for their take so far and how they conducted the tests; and they promise to release full test results next week.
