Tesla just deliberately rolled out an update to make its cars go slower

Tesla has introduced a Chill Mode for its Model S and Model X electric vehicles, toning down the rapid acceleration its EVs are capable of.

A software update introduced the Chill Mode, which can be accessed via the on-board infotainment screen. In the software update notification it says Chill Mode is “ideal for smoother driving and a gentler ride for passengers.”

The setting can be particularly useful in the Model S 100D, which in Ludicrous Mode can accelerate from 0-60mph in 2.5 seconds. This makes it faster than almost any vehicle currently on sale. In Chill Mode, that 2.5-second figure will not be possible, nor can the driver use the full electric jolt of 603bhp and 967Nm of torque from its 100kWh battery pack.

 Chill Mode isn’t the only new feature in Tesla’s latest software update. An ‘Easy Entry’ system has been downloaded onto Tesla EVs, which gives drivers’ easier access getting in and out of their Tesla.

When parked, the vehicle automatically adjusts the steering wheel and driver’s seat so that exiting the vehicle doesn’t turn into a laborious process. The software will remember the driver settings so that when you get back into the vehicle and step on the brake, it will return to the driver’s preferred driving position.

Elon Musk promised the upgrade back in August, after responding to a driver’s tweet requesting easier entry and exit in and out of his Tesla.

The update follows last month’s speed boost which saw Tesla unlocking extra power in older Tesla Model X and Model S 75Ds. Earlier in the year, Tesla said it had found a way to increase the performance of new 75D models and this has now filtered down into the older models. The update only works on a certain hardware configuration introduced midway through production, though, so not all 75Ds will be able to benefit.
