Here is the video of Elon Musk's presentation at the launch of the Dual Motor Model S and Autopilot.

He was obviously trying to portray an image of Robert Downy Jr's portrayal of Iron Man, but the stuttering and what not didn't quite sell that completely. Regarding the tech, a lot of it is nonsense. Active differentials can distribute the power on AWD vehicles just as well, and because there aren't four wheel in hub motors, you still have to use differentials to get the power to the four wheels, and you still have to be able to distribute torque to them through limited slip or torque sensing differentials all the same or the inside tire without traction would just spin like crazy.
So that's all a whole bunch of nonsense.
Regarding autopilot, that's not really unique to electric vehicles, and is something that many different groups have been working on.
And while he talks about matching the performance of a McLaren F1, a car that ended production back in 1998, his metric is a fast 0-60mph time. The McLaren F1 is not a drag car though, what makes it special is the handling and its ability to kick ass on a racetrack. The Tesla cannot kick ass on a racetrack, as it doesn't handle that well and it literally overheats and goes into limp mode after a relatively short period of time. So, no, its not as good on the track as a car from almost two decades ago.
But I understand the need to build hype and market what you're able to produce as best you can, I just hope people aren't uneducated enough to realize that this is an immature technology that is inferior to alternatives available.
While I agree that the only D here was disappointment, I strongly disagree with your last statement. The tesla model s is an amazing vehicle that is competitive with other cars near it's price range. The F1 was never near it's price range nor are high end track cars. I'm not saying he model S is cheap or even reasonably priced for most of us. However, if you compare it to other high performance luxury cars around 100K it's pretty damn competitive. In addition it's electric so you don't have to deal with gas stations or oil changes.
The car is quite exhilarating to drive because of it's torque at the low end and near silent operation. If I was single and didn't have kids I would pick one up. Several of my coworkers have them and they are about the nicest daily commute car with muscle I could imagine having.

It's been a long time since I've been involved with 4-wheel vehicles, so I'm unfamiliar with what mix of mechanical and electronic methods other companies currently use for dealing with 4-wheel drive or providing limited slip.
That said, an active mechanical differential that is powered by a single engine and uses mechanical means to distribute that power will be inherently less efficient that two separate motors that are kept in complemetary operation via electronics.
This would also be applicable to limited slip/torque sensing.
How well Tesla implements the process, of course, remains to be seen.

Yeah, tell me about it, had to turn that off. I wonder if he has some sort of medical condition associated with this, akin to Parkinson (or hell maybe even just that).The dude's a genius, but damn is he hard to listen to.
True.Zarathustra[H];1041155538 said:I agree under most circumstances.
The only time this wont be true is if one end (front or back) has very little traction and the other has lots. In this case a mechanically linked system with one engine will be able to transfer all (or most) of its power to the end that has traction.
A two motor solution will only be able to max out the motor on that end.
This is mostly theoretical though. For most practical uses I think a dual motor solution will be just as good as (if not better than, due to the instant on response time) as compared to a traditional mechanically linked solution.
I'm glad you think so, but you're wrong, and as I said, the two motors still have to use two differentials to power the four wheels... mechanical means to distribute power.That said, an active mechanical differential that is powered by a single engine and uses mechanical means to distribute that power will be inherently less efficient that two separate motors that are kept in complemetary operation via electronics.

The only difference is that you don't need a center differential, that's it. And its rather pathetic that the Tesla is using open differentials in the front and back, I didn't realize that. That means the only way it can keep the tire with lower traction from spinning and giving no torque to the other wheel is by applying the brake to it.
That is way less efficient than an active torque sensing differential.

This is a very shallow and superficial post. Still rocking your iPhone? It beats watching smooth talking schmucks about another useless phone year in, year out.
Dude grew up in south africa, give 'em a break.
Da fuck? I've gone on extended rants about how close Steve Jobs and Hitler are in personality and life events. And pointing out that the guy is trying to emulate an Iron Man movie poorly doesn't have anything to do with my de-hyping technical analysis of the technology's current limitations, in how it falls short of the nearly two decade old supercar they erroneously say it now equals.This is a very shallow and superficial post.

one of the things he mentioned is with 2 motors range increased. i wonder if they are using a more energy efficient engine on this vs the toher.

Most people don't cut it as public speakers... Who gives a fuck?
I need subtitles for this.Don't worry he wishes he was could talk this bad and be as smart as make as much money lol.
The worst thing about this is that all of us with P85s took a bath in resale value essentially overnight!
