That has been talked about but nothing official.
Roadster - new options
And, my opinion (from 19th March):
Sounds like they are building their own Tattler / OVMS?
I doubt it. Speaking for OVMS, and as a v2.5 Roadster owner and Model S reservation holder, I would really love to have Tesla extend their Model S iPhone app to roadster owners. However, the v1.5 vs v2.x vs Model S are worlds apart in terms of functionality.
- The v1.5 roadsters have no GSM hardware built in. To support these cars they would need to add on a hardware module, and that would be a lot of work (I know, I've done it). A huge investment for Tesla, considering it is < 500 cars.
- The v2.x roadsters have the GSM hardware built in as well as a link back to Tesla HQ. To support these cars, Tesla would presumably need changes to the roadster firmware, plus extensions to their server infrastructure, plus extensions to the App they have built. Not too difficult.
- The Model S cars have it all, and the Tesla App has already been built for it. It was designed that way from the start, rather than a retro-fit.
The v2.x roadsters are certainly close to the Model S in terms of the hardware needed for this, but the questions of who pays for the data plan and getting the firmware, server and app changes made are not trivial. The big question is whether Tesla will invest the engineering time into doing this - I hope they will, but realise that Model S is what will make/break Tesla not supporting Roadsters with new features. My biggest hope would have seen them doing this with the justification that it would be a test bed for the Model S App and Server rollout. Something they could do to work out the kinks before the Model S is launched. But, that would have meant we would have seen it by now, and we haven't.
To put this in perspective - anyone over 5'9" tall has been crying out for Tesla to replace the readout in the speedometer with a digital speedo (rather than amps/trip/whatever). The inability to simply see the speed you are travelling has been a problem affecting roadster owners for years. I've seen the bus messages, I've prototyped the fix, and I know it is literally a few lines of code to be changed in the VMS and instrument panel code. It is really that easy. But, Tesla haven't invested the engineering to get that simple feature added. The reason? Even for a couple of lines of code, they would have to (a) test it, (b) validate it, (c) certify it, (d) update the documentation, (e) update/educate the owners, (f) deal with the fallout if there were any regression issues introduced.
In the past 18 months, the firmware updates we've seen include a new memorial screen, cabin temperature tweaks, and support for new headlights. Tiny tweaks.
The last major change was the new drive information screen in 4.2.30/4.2.34 and that was a long time ago.
Don't get me wrong, I'm not complaining about Tesla not doing this. Given a choice between this and work on the Model S, if I was Tesla it would be an easy decision. The Roadster owners are important to the future of Tesla, just not so sure about the Roadster itself.
