The Tesla Model S vehicle is currently in Alpha testing. Tesla's retail chief George Blankenship just revealed pricing specifics for the vehicle.   (Source: Tesla Motors )
$20k USD will buy you 140 extra miles of range

George Blankenship, former Apple retail chief (and an ex-executive of Gap, Inc.), has been a critical force in driving Tesla Motors Inc.'s strong continued sales of its Roadster EV while the company awaits the Model S.  On Monday Mr. Blankenship, the company's new Vice President and retail chief, blogged on a recent meeting at the opening of Tesla's latest store in Milan, Italy.

Apparently Mr. Blankenship and company CEO Elon Musk were met with plenty of questions about the Model S, including details on the battery and pricing.  And, surprisingly, for the first time in some time they offered precise answers.

According to the pair, the Model S is well into Alpha testing, which began with Alpha vehicles hitting the road in December 2010.  The production-intent beta vehicle will be assembled this year at the new Tesla Factory in California, though the precise month was not revealed.

In the realm of more concrete details, the Model S will be produced with a variety of battery options, at a variety of prices.

The longest range model, the Model S, will be priced at $69,900 USD after $7,500 USD U.S. federal tax credit.  It will get 300 miles on a full charge.  230 mile and 160 mile variants will also be offered for $59,900 and $49,900 USD, respectively after federal tax credit.

But there's one caveat.  The Model S "Signature Series" -- a special 300 mile-range model with additional luxury options, still has its pricing up in the air.  That's a major unknown, given that the first production run will be composed exclusively of "Signature Series" models.

The pricing on the Signature Series will be announced this summer.

As to Tesla's shipping schedule, the company says it will produce and ship 1,000 Model S Signature Series vehicles in "mid-2012".  Later that year Model S production will partially shift to the 230 mile and 160 mile variants.  In total 5,000 Model S variants will be assembled and shipped in 2012, if all goes according to plan.

Then in 2013, the production will ramp up to 20,000 units over the year.  Among those will be the first right-handed variants, which will land in "mid-2013", destined for Tesla's European and Asian markets.  Prior to that, Tesla will exclusively be producing left-handed (e.g. North American) models.

Tesla is in the midst of taking the plunge of developing a mass market EV.  That process has thrust the company deep into the red financially, but it promises big rewards if Tesla is correctly predicting the demand for an entry-level luxury EV.  The company is also buoyed by EV-related contracts with Toyota, U.S. Department of Energy high-tech loans, and hundreds of millions of dollars raised by a highly successful initial public offering of stock.

You probably should've kept reading that wiki page on Lithium Ion battery history beyond them being theorized in the 1970s. The first commercial Lithium Ion battery was released by Sony in 1991. There have been numerous advancements to Li-Ion technology over the past 20 years.

Yes there are a ton of people experimenting with and testing new battery ideas along with ultra capacitors and some of them do hold promise. It's pretty asinine to believe Li-Ion is the end of the road for batteries.. If that's what you truly believe though, I'm not sure why you bother visiting tech websites.

It took 50 years for HDTV to come out somethings take longer than others. And the problem with the battery materials is that they are sourced from China. So by going EV we go from being reliant on Middle Eastern Nations to being reliant almost exclusively on China as they have 97% of those materials.

The point was I'd rather spend money on subsidizing a new technology that could turn into something to curb our dependence on fossil fuels than on wars. What's it going to cost to subsidize the electric car while they try to reach economies of scale? $50 million? $100 million? What's that in terms of how much we spend on wars? A drop in the bucket. I just don't see much point in complaining about some trivial spending on a new technology when the government wastes billions on other endeavors.

Think of all those poor souls who wouldnt be able to afford an electric car without the tax credit! The tax credit goes straight to Tesla - its built into the price.

Now if there was a requirement that the car had to be below 25k for the tax credit and required significant sales numbers, than that would actually achieve a goal and drive some growth.

I see no reason for subsidizing Model S buyers, since the car is worth the price. As for those who one claims can go buy a $35K BMW and so on... needs some education. No $35K BMW is competitive with the Model S. Pay $65K or $70K and you might find a model that can compete. Lots of ignorance
here about batteries, I see. With 300 miles of range, the ONLY time one will need a public charging station or to charge/discharge completely is during a trip. And level 3 charging stations, which is the only type that makes sense, doesn't require 3 /12 hours to recharge. The Model S, regardless of battery pack, can recharge in 45 minutes, usually less. Whether one charges
all the way to full and discharges below 10% (the safe level, despite the Volt's system), is up to the owners, but doing so occasionally while travelling is hardly going to have much effect on the battery pack's lifespan. And fast charging has zero effect on lifespan - MIT proved that several months ago. If you think their battery pack is expensive, why not walk into a Mercedes parts department and ask what it would cost to replace a MB engine, tranny, cooling system, exhaust system, and fuel system? The Tesla electric motor costs peanuts to rebuild and is infinitely less likely to need repair. That battery pack is now looking pretty cheap, and anyone can easily save 80% or more off their gas fuel bill, not to mention oil changes, fuel filters, air filters, etc.etc.

I could see owning a Tesla S series car, but spending an extra $20k for a longer range battery pack I don't see as valuable to most people. The electric car won't be used for long road trips since it would be a pain to recharge for 3.5 hours every 300 miles. The daily commuter would benefit from an electric vehicle, but they wouldn't likely ever go more than 160 miles in a day of general driving. Since you can simply recharge every night, the extra capacity would be largely wasted I'd imagine.

The way I envision the electric vehicle fitting into the grand scheme of things for me, would be a daily commuter for limited range driving, and anything over 100 miles I'd use a diesel car for.

I think 150 miles is a minimum acceptable range for me. My usage would include daily commutes, but also day trips for the weekend. I think 150 miles is the minimum acceptable range for a reasonable trip to the beach or the mountains for a hike.

If the car actually gets 160 miles, it's great. If it gets 160 miles in dry 65degree environments with no AC use, this wouldn't work for me.

Granted, this is a luxury item that I can't afford. If I could afford a 50k car that only goes 160 miles on a charge, I could probably also afford a 60k car that goes 230 miles or a 70k car that goes 300 miles. I'd be willing to bet that Tesla sells more 300 mile cars than 230 and 160 combined...

I was mainly talking about the daily commute to and from work, not weekend roadtrips over 100 miles.

The average American commute to and from work is 30 miles round trip. 160 mile range is more than adequate for the average commute.

Sources for average commute (though they aren't terribly recent, the average over the years they do show doesn't change that much with the exception of travel time.

Regarding your comment about the battery life I have extracted some text from teslamotors.com FAQ section on the S series http://www.teslamotors.com/models/faq:

How does Model S perform in extreme temperatures?
Model S is engineered to perform in extreme hot and cold weather. The sophisticated Tesla battery management system uses re-circulating propylene glycol to either heat or cool the battery as necessary.

Do Tesla battery packs suffer from "memory effect?” Is it necessary to completely discharge the battery to maintain its capacity?
No. Tesla uses lithium ion cells, which do not suffer from memory effect.

If Model S is parked and not charging, will the battery lose its charge?
Loss of charge at rest is minimal. For example, Model S owners can park at the airport for extended vacations without plugging in.

How does accessory use (radio, climate control, headlights) affect driving range?
Accessory use does not have a dramatic impact on driving range. Exact range fluctuates based on vehicle speed, driving style, road conditions, and weather. Holding these factors constant, using higher consumption accessories like climate control will reduce range approximately five to ten percent

Most of the LI battery packs in cars are not charged to full capacity nor are they discharged to zero either. A "buffer" is left in the pack to counteract the eventual loss of capacity you get.

Then went on to say:

Doesn't sound like daily commute talk to me. Regardless, 150 miles still wouldn't be enough range for the type of driving that YOU spoke of. Maybe if I lived in Malibu. The mountains there are within minutes of the beach. Nope! I've read of Malibu residents that ran out of juice in their Tesla's romping through the mountains there. And we know those cars have more than 150 miles of range.

My original post..

My reply about the weekend day trips still applies and by your comment about 2 hours to the beach and really close to the mountains, if there was a charging station at your destination then it sounds pretty doable with a 160 mile range. Unless of course by 2 hours you mean driving for 2 hours at a greater than 80mph average.

Obviously I haven't done any real world testing here in MN since I don't own one nor do they sell them here. For now I'll trust the specs within +/- 20% of what they claim versus hearsay.

I truly don't believe this for a second. If the range is 160 miles on a sunny spring day then in the following scenario it certainly is *much* less than 144 miles (10% less):
Leave home in January (car garaged overnight & fully charged).
Outside temperature at 5:30 AM is low single digits F.
Headlights, electric heat and window defrosters (including rear window in glass defroster) all blasting away.
Drive 60 miles to work (yes, I've done that commute many, many times).
Park outdoors in the parking lot -- no plug in.
High temperature that day is still single digits F.
(Car is either expending energy to keep the batteries warm for those 13+ hours or the batteries get very, very cold. Either way at the end of the day the effective/available energy is less.)
Leave work at 7:30 PM (yes, I often pull long days) in the dark with outside temperatures in low single digits F.
Drive 60 miles home with headlights, heater, defrosters, etc. on.

Will I make it the full 120 miles round trip? Maybe, but I doubt it with a 160 mile "spring weather & daylight" range. In extreme conditions the impact will be much more than 5 to 10 percent. I would not be at all surprised if the impact is 25% or more under these conditions.

The batteries getting very cold doesn't reduce the amount of energy stored in them, only the ability to access it. The batteries only need to be warmed up again once you go to drive.

The headlights won't pull that much considering the size of the battery pack. The heater would probably be a considerable load though.

Anyway, your 'belief' isn't backed by any factual information or related expertise so to be claiming any idea of what percentage of the range that would be lost is meaningless. Do you even know the actual capacity of the battery pack?

At below zero temps the ability to crank and start a car that has not been in a garage is greatly reduced.
At really low temps the car might not start.
So the expectation that this battery powered car will -
1 - heat the driver on his commute- remember heating takes a lot of power
2 - keep the windows clear - heating as well
3 - make the 60 miles that he drives - and at freeway speeds

I don't need Comsumer Reports to tell me that the battery will be greatly affected by these conditions. As such the strickly battery powered cars are not fuctional for us snow bound commuters to us.

The Focus is interesting as it gets 38 mpg hwy and it's comes loaded at $25k. It looks good and has very nice options (including MyFord Touch). The Edge and Accord are both 27-28 mpg which is our goal. Anything more is gravy. I prefer the Edge. Good sized gas tank, lots of room inside, 27 mpg, MyFord Touch, and surprisingly great ride and handling. I understand that there is supposed be an Ecoboost 4 cyl for the Edge sometime but unless it gets in the mid 30's mpg AND keeps the gas tank size and options of the V6, I'm not interested.

Biodiesel is still progressing rapidly. There's a patent app out there pending for a way to utilize water treatment plants of our sewage lines which skims the lipid wastes off the top. I don't know the specifics on how it works but it's basically a skimming process and the costs to produce a gallon of biodiesel from that waste was next to nothing.

Then there's algae which can be economically viable at 5000 gallons per acre yield.

Now there's this cyanobacterium which is supposed to be capable of 15,000 gallons per acre.

So Biodiesel will grow organically without any government subsidies is my guess since it's economically viable with the above mentioned sources.

They really should advertise the car at full price because that's what you're paying when you show up at the dealership. Not that it really makes a difference to me and most people in this forum.

Hah, the US government got soo duped. I suppose with all your knee-jerk reactions to sensationalist garbage; who's to say its not well deserved?

To get 300 miles from an electric vehicle, assuming 4 miles/kWHr (which is generous), you'd need 75kWHr of usable battery capacity.

Now we know that you can't use all of the battery capacity or you will kill the battery in short order so let's say they use 75% of the capacity (GM uses 65% in the Volt). This means the total battery capacity would have to be at least 100kWHr. The Volt battery is 16kWHr and weights about 400 lbs. This means the S battery would weigh more than a ton. A lot more actually.

And the cost would be astronomic.

Like I said, can't wait to see how they're going to do this.
