If the Tesla's 50 kWh battery pack was almost fully discharged it would take around 7 hours to recharge from a 220V 30 amp outlet. There are special charging stations that can deliver power a lot faster. The Altairnano 35 kWh battery pack can be re-charged in 10 minutes at one of these high capacity charging stations. However I don't believe the batteries in the Tesla can accept a charge this fast even if it was available.
 
So basically your roadtrips will be limited to ~200 miles. Probably not a big deal. If you consider this car to be an electric Dodge Viper then ask yourself, how many 200+ mile roadtrips do people make in Vipers? Probably not many. These types of cars are toys and not meant to be practical and shouldn't be judged from that perspective. But even as a toy the Tesla will be a valuable proof of concept testbed.

However the sedan doesn't seem to be like it should be considered a toy. Hopefully it will have much faster recharge capability so that it can be considered as a family car for local and long trips.

I do not think you will see an EV that is practical for long trips. The target will be commuter and local drivers. Even if your car has the means to be fast charged and a 300 mile range. What are the odds of there being a fast charge station where you plan to be? The fast charge home units that were available for the old EV-1 were about $4k and you had have new service run to your home. The all in one EV may never be built. At least in our lifetime. Too many logistical problems to overcome.

Have you ever taken a 300 mile trip that didn't involve passing rest stops? I don't think it would be all that an ambitious undertaking to equip rest stops with these fast-charge stations. I also think it could be a money maker. Selling the electricity for 20 cents per kWh would be a 100% markup but still vastly cheaper than gas. For your typical day to day driving that involved shorter distances the slower, overnight charge would be adequate.

I avoid the Interstates when ever possible. That is the only place you see many rest stops. I just do not see it happening. I believe all the charging stations for the EV-1 in CA were paid for or subsidized by the state. My local Costco had two. Now they are gone. Money down the old toilet so to speak.
 
Think of all the trips you have taken. I like the back roads of America. I like taking the trail of "49" etc etc. To cover all the areas that people might drive would be a huge investment. With many places never being used. I could be wrong. Something new in storage will have to emerge before we see much to be happy about. If I could justify a small errand electric vehicle I would. At this point it would just be to satisfy my desire for something different. Anything over $15k would be frivolous as a runabout.
 
Another thing to consider with a cross country charging system. Compatibility would have to be established. I don't think all the EVs built during the CA ZEV fiasco were able to use the EV-1 charging stations.

I meant in the way distant future it would be nice, not with what we have now, or in the next few years, rather 20 years from now. I can not see it happening at all in the next decade, except for commuters. The Tesla of course in not a family car and not for the average citizen. But just the idea being thrown around is exciting and I thought I would, so I didn't mean tommorrow rather in the next 2 decades for those that misunderstood me.

I would strongly agree that without a standard being established for quick recharging, the EV will never be more than a local commuter.
 
I believe that existing gas stations will be around for quite awhile. I think that it would be very worthwhile for this existing infrastructure to include providing electric recharging service, at least at those stations that are primary stops for interstate travelers. While the initial expense in providing the service won't be recovered immediately, it has the long term potential of being very profitable with minimal upkeep.

That's for sure. It's a lot simpler and cheaper to transmit electricity than it is to transport gasoline. I also agree that it could be very profitable. It will be one of those chicken and egg situations at first. No one will want to build re-charging stations until there are EVs and people won't want to buy EVs until there are charging stations.
 
I believe that Phoenix Motorcars is delivering their first vehicle in the next couple of months. So we should soon be getting some real world feedback on how the newest generation of EVs performs.

The Tesla at $50,000 ???? by sunray1

I saw a video the other day featuring the head guy at Tesla, and he was saying that his vision was to start with a more expensive car, then work his way down to something most people can afford....
 
Here's the thing. I'll bet you dollars-to-donuts that when the price of a Tesla vehicle comes down to, say, $30 grand or so, so will the relative attractiveness of the vehicle.....
 
I want the Tesla roadster for $30 grand....or 40, not some Hyundai-looking sedan....Maybe I'm paranoid, but if that actor from Oceans 11 bought one, he may be upset if Tesla offers the same cool vehicle to the masses......
 
Maybe I need a better-paying job.....

I don't think that he was ever talking about making the Tesla Roadster affordable for the masses. I've read several interviews with this guy and I believe what he is saying is this. The nature of EV technology right now necessitates that they will be expensive, very expensive. That being the case he started out building an exotic car aimed at people that aren't all that concerned with practicality or cost. As EV technology matures and gets more affordable he will build completely different vehicles targeting different markets.
 
I've said this before and people have disagreed. I personally feel that Tesla will be bought out in the next few years by someone like Ford or Chrysler. We'll see.
