Tesla has released details of an impending software update, for the 2012 Tesla Model S electric sedan.

Among the changes, owners will now be able to use new features like an app launcher and voice commands, while seeing improvements to some of the controls, and even acceleration response.

New features

First of the new features introduced in the update is a "vehicle sleep" mode.

This is aimed at reducing energy use while the vehicle is off, powering down the vehicle display and electronics to a "sleep" state when the car is turned off.

Tesla notes that this does mean the displays will take a little longer to boot up, but drivers can choose whether to turn this feature on or off. Turning it on is beneficial to those who may not recharge every time they're parked up--the company says that leaving the displays on uses the equivalent of 8 miles of energy per day when the car is not plugged in.

An App Launcher is also included in the update, letting users pick where they wish a launched app to be displayed--in the top or bottom half of the screen--by dragging and dropping the item on the touchscreen.

Finally, voice commands are now available.

Drivers can use this to listen to music, use the navigation system, or call contacts--all using simple commands like "listen", "drive to" and "call", while holding down the voice command button on the steering wheel.


A series of subtle enhacements are included in the updates.

Most noteworthy are the synchronized door handles and the improved throttle response.

The former means that all doorhandles now present and retract together. All door handles will remain extended for a minute after the last door closes, before all retracting in unison.

The latter will also be welcome for Model S drivers. The car has never been short on speed, but Tesla has re-tuned the "throttle" response for what it calls a smoother, crisper feel. This should make the Model S even quicker in real-world driving.

Additionally, drivers can switch the vehicle alarm on or off, choose between metric or imperial units, choose whether the door handles auto-present when unlocking the car, and a 'Range Driving Mode' reduces the climate control's effectiveness to the benefit of conserving range.

Model S owners will be presented with an update scheduling screen when the update becomes available, and the software will be updated wirelessly.

  1. Is that picture of the white Tesla the 2012 as labeled or a prototype? looks different.

  2. Having all the door handles pop up would save you from having to explain how they work every time.

  3. This is great!

    The Leaf announces the same improvements... from now on, these cars are gonna get more and more advanced.


  4. Accordig to Tesla specifications (*1), the Model S uses about 300 Wh/mile, so that makes 2.4 kWh for 8 miles. If the computer consumes so much energy in a day (24h) we can conclude that it has a power consumption of about 100 W in idle mode.

    This is a huge amount of energy. Those embedded systems are supposed to use low power processors, such as Intel Atom, ARM or something in that category. The power usage of the computer should not be bigger than, say, 30W.


  5. 100W isn't exactly bad in "on" mode.

    If you leave a computer in "on" mode, not in "sleep" or "hybernate", it can easily draw up to 30-50W of power without anything running. Telsa's system is constantly monitor all the system to ensure the car is ready to go.

    Also, display also draw a lot of power as well. "the company says that leaving the displays on uses the equivalent of 8 miles of energy per day "

    So, if the dash display is always on, I am willing to bet that it is at least another 50W of power to keep the display on.

    That is easily 80-100W of power per day. No different than keeping your laptop on all day without the screen going into "saver" mode.

  6. The door handles is the biggest small improvement to this car. I went by a Tesla store last weekend (I'm a huge fan of Tesla) and was shocked to see a door almost take a customer's finger off. Definitely something that they needed to fix ASAP.
