Tesla Model S guide: The first full- production model

See All Stories

The Tesla Model S is an all-electric luxury sedan and the first vehicle developed from the ground up by Tesla. The Tesla Roadster was the first vehicle developed by Tesla, but it was based on a chassis by Lotus.

Tesla Model S

History of the first volume production Tesla

The Tesla Model S is an all-electric luxury sedan and the first vehicle developed from the ground up by Tesla. It was originally unveiled as a prototype in 2009.

The Model S sedan also sits as Tesla’s longest-running EV in production to date, making its official debut in 2012, three years after it debuted as a prototype. At the start of production, Tesla was completing 12-15 Model S EVs a week.

By 2015, that number had grown to over 1,000 per week, helping the Model S reach its reign as the best-selling plug-in electric vehicle in both 2015 and 2016.

The time of the launch of the Model S is when Tesla also began building out its Supercharger network, which now consists of over 16,000 locations globally.

Early owners of the Model S also qualified for free Unlimited Supercharging, a perk that is much harder to come by these days.

In recent years, sales of the veteran Model S have dwindled in comparison to Tesla’s more cost-friendly Model 3 and Model Y EVs, but it remains a premier sedan offering luxury and performance, especially following its latest refresh and upcoming Plaid powertrain.

Performance Specs

The Tesla Model S currently comes in two different AWD trims – a dual-motor Long Range and the tri-motor Plaid.

The newly refreshed Model S Long Range offers an EPA estimated range of 405 miles, can hit a top speed of 155 mph and can travel 0-60 mph in 3.1 seconds.

The previously available Performance trim of the Model S was dropped when the EV saw a refresh from Tesla in 2021. It has since been replaced by the highly anticipated Plaid tri-motor powertrain.

This version travels an EPA estimated 396 miles on a single charge and can hit a top speed of 200 mph. Additionally, the Plaid Model S can zoom from 0-60 in 1.99 seconds.

Most recently, the Model S Plaid has showcased its hot track times at the Nürburgring racetrack in Germany. In late August, the Plaid actually crashed into a barrier while attempting to break some track records. Luckily, the driver was ok.

A week later, we reported footage of the Model S Plaid once again tearing up the track at Nürburgring. In fact, the Plaid actually ended up setting a new electric lap record, with a time of 7:35.579.

Plaid+

In 2021, Tesla began touting an even faster version of the Plaid powertrain with the unveiling of the Plaid+. This trim was advertised to offer the same speed as its Plaid counterpart but with a 520+ mile range on a single charge.

Not long thereafter, however, Tesla scrapped the entire trim as its CEO declared that drivers don’t need more than 400 miles of range, and the regular Plaid is “just too good.”

Here’s a rundown of how everything transpired around the short rise and fall of the Plaid+:

Other features

In addition, the Plaid tri-motor powertrain and nasty speed increase, the latest refresh on the Model S, brought updates to the interior.

This includes a second touchscreen for rear passengers, as well as a new yoke steering wheel. When Electrek first reported the yoke steering, we were seeing some early versions of the Model S with a regular round wheel.

However, Tesla CEO Elon Musk has since come out and stated that the yoke steering wheel is here to stay. At least on the Model S and Model X.

Last March, Elon Musk stated that the new Model S would come with a rear-facing, third-row seating option, but we have yet to see it.

Most recently, Tesla pushed a new software update to improve the Model S’ suspension, Autopark feature, and more. This was followed by an additional software update that enables Sirius XM radio and “immersive sound” in the new Model S.

How much does a Model S weigh?

This is a common question for prospective Tesla owners, especially those looking to maximize speed… or practice deadlifting their EV for workouts.

The current Long Range version of the Tesla Model S weighs 4,561 lbs., while the Plaid and its additional motor weigh in at 4,766.

The Model S remains the second heaviest Tesla behind the Model X — at least until the Cybertruck begins deliveries.

How much does a Tesla Model S cost?

This is an important question for anyone even briefly pondering purchasing a Tesla, especially the more luxury-end Model S. The final purchase price depends on a number of factors, including powertrain, customizations, and add-ons such as Full Self-Driving capabilities.

To give you the best range of pricing for a Model S, we have shared the lowest-priced, bare-bones model and gone upwards to the fully loaded version of either trim.

Note that all prices are relevant at the time of this posting and do not include any taxes, destination fees, or federal tax rebates.

The Long Range Model S is the lower-priced of the two versions currently available. This dual motor AWD trim starts at a purchase price of $89,990 and can go as high as 108,990 all in.

This higher price includes all available add-ons such as red paint, custom interior, and FSD capabilities. It also includes 21″ Arachnid Wheels, which bring the EV’s estimated range down to 375 miles.

The Plaid Model S begins at a purchase price of $129,990 with white exterior paint and zero upgrades. If you were to add every available feature listed above, the Plaid can go as high as $148,990.

Again it’s important to note that the Arachnid Wheels upgrade will not only cost $4,500 but will also lower the Plaid’s estimated range to 348 miles.

All in all, you can get yourself a newly refreshed Model S for $90,000 minimum and can go all in on a souped-up Plaid for $149K. Either way, you may have to wait a bit longer for delivery, especially on the Long Range Model S.

If that’s too much money, you may be able to find a cheaper Model S for sale near you.

Have Model S prices gone up?

They certainly have. While the Model S has always been one of the most expensive Tesla models in the current fleet, it has seen additional price hikes recently, beginning with the 2021 refresh.

Here are some previous articles to get you up to speed.

How long does it take to charge a Model S?

After the pricing question, another common one to follow is How long does it take to charge a Tesla? Just like the pricing, a number of factors contribute to how quickly you can get your Model S juiced back up.

First, it’s important that you clearly understand the EV charging standards and how they vary. Then, you’ll know the three levels of charging and what sort of times you can expect.

Charge times will most certainly vary based on these factors, but here’s a broad breakdown of charge speeds for a Model S.

  • Level 1 AC (110-120V outlet at home): 20-40 hours
  • AC Level 2 (220-240V – Third party chargers/Tesla chargers/Tesla home charger): 8-12 hours
  • Level 3 DC fast charger (480+ volts – Third party chargers/Tesla Supercharger): 15-25 minutes

The Tesla Supercharger network is the best for speedy charging, especially on a road trip or for a quick recharge when you’re running super low.

However, due to their massive direct current (DC), Superchargers are not recommended for daily use.

Tesla recommends Level 2 charging at home if and whenever possible.

For more pertinent details regarding Tesla’s Supercharger network, check out our detailed guide.

What is the max Supercharging power available on the Model S?

Currently, either trim of the Tesla Model S can handle up to 250 kW of power on a DC fast charger.

However, Elon Musk has recently stated that Tesla plans to up the Supercharger network to 300 kW.

That may eventually require an upgrade to the Tesla’s themselves to handle such power, but that can likely be accomplished through an over-the-air (OTA) software update.

How much does it cost to charge a Tesla Model S?

Different question, same answer – it depends. In this case, pricing depends on a lot of factors. This includes what state you live in, whether you’re at home or on a public charger, what time of day it is, and how long you’re charging.

By using annual data of the average residential energy costs in the US from the Energy Information Administration (EIA), we have calculated an estimated cost to charge both at home and at a DC Fast Charger.

Cost to charge at home

To begin, we’ve calculated that the 100 kWh battery pack on the Model S will cost approximately $16.47 to charge at home on a Level 1 or Level 2 AC charger from 0-100%.

Since the charger must convert AC power into DC for the Tesla, we’ve also accounted for an 85% charging efficiency in that price. For more information on how to determine these prices and what the heck charging efficiency is, check out our Tesla charging guide.

It’s also important to note that while these prices are the cost to charge your Tesla battery from 0-100%, you should never let your battery get down to 0%. Furthermore, you should rarely charge your EV all the way to 100% unless you need maximum range for a long trip.

Speaking in terms of mileage, the Model S Long Range has an EPA estimated range of 405 miles, which means you’d pay about $0.041 per mile or $4.07 for 100 miles of range.

The Model S Plaid has an estimated range of 390 miles, coming out to $0.042 per mile or $4.22 per 100 miles.

Cost to charge on a Tesla Supercharger

Considering the 100 kWh battery pack on a public DCFC like a Tesla Supercharger, drivers can charge from 0-100% for approximately $22.95. This accounts for a 95% charging efficiency since less energy is lost on DC chargers compared to AC Level 1 and Level 2.

The Long Range Model S costs about $0.057 per mile and approximately $5.67 for 100 miles of range. At a lower estimated range, the Plaid version of the Model S can cost you about $0.059 per mile and $5.88 per 100 miles.

Model S FAQ

Is the Model S the first Tesla?

Close. The Model S is the first Tesla to reach volume production. The original Tesla is the Roadster, but only about 2,450 units of that EV were produced.

What happened to the Tesla Model S Plaid+?

Great question. This past June, Elon Musk Tweeted that Plaid+ had been cancelled because the Model S Plaid “is just too good.” When asked to elaborate, Musk said that Tesla no longer believes drivers have any need for over 400 miles of range.

Can I lease a Model S?

Totally. However, we recommend you doing your homework and research to see if a Tesla lease is better for you than buying. Used Tesla values have been soaring lately, so it’s worth at least weighing both options. Check out our Tesla lease guide for more.

What’s the closest Tesla to a Model S?

Considering they’re both sedans, the Model 3 is the most similar Tesla, although the Model 3 is smaller and much much cheaper. Mechanically, the Model S shares more of its DNA with the Model X as they both sit upon Tesla’s 2nd generation platform.

Does the Model S qualify for free unlimited Supercharging?

Most versions of the Model S have previously received some offers of free unlimited supercharging at some point. However, Tesla has made no mention of free unlimited Supercharging for any models since 2020. Learn more here.

Tesla ends the year with 50 US superchargers and most of the East and West Coast covered

Site default logo image

What you are looking at above is the state of the Tesla Supercharger network on The last day of 2013/first day of 2014.  Tesla counts 50 Superchargers in the US (1 per state!) and another 14 in Europe. While Elon Musk originally planned to take his family on a Christmas holiday across the country, there are still some rather big holes to fill.

Those holes all fall in the “coming soon” category and if you take a look at this helpful 3rd party map, you can see a lot of the country is still being built.

ExtremeTech reviews the Model S: “Go ahead”

Site default logo image

Another Tech site reviews the Model S. Conclusion?

Should you buy a Model S? Go ahead. It’s not your only car…

If you have the money, go ahead and get a Tesla. If you can spend $75,000 on car, odds are you already have another $75,000 car in your garage already, something like an Audi Q7 diesel. That takes care of range anxiety on really long trips, that or renting a combustion engine car for the weekend. With all respect to Tesla, I think the hassles of finding fast-charging stations are still a lot to deal with. The score currently reads: US gas stations 120,000 and slowly declining, Tesla Supercharging stations 44 and growing. On the New York to Boston and back trip, it was fun, especially chatting up other Tesla owners. Do it regularly and it could be a grind. But as more Supercharging stations become available, the hassle factor falls off, and for daily driving or weekend recreation trips, the 200-plus miles of range is more than enough.

ET Editors' Choice badgeThis is a car unlike no other. The same goes for the dealer network. Name one other vehicle that carries four plus cargo, that your neighbor doesn’t own except in Atherton, gets to 60 mph in as little as 4.5 seconds, has an LCD display big enough to be seen from low earth orbit, uses less than $10 worth of energy per fill-up when it’s not free, and — try this in your Porsche Cayenne — lets you slip into the HOV lane as a solo driver. You will be hooked.

I agree and I don’t think the “only car” angle is played up enough. Sure Tesla would like you to think that this can be your only car, and it probably could be if you live on the West Coast. But the reality is that most drivers have another car laying around for those trips into the Flyovers.

Tesla pushes back Supercharger station rollout moving Fall and Winter into “Coming Soon” category

Tesla rejiggered its Supercharger map today moving Fall and Winter 2013 into a “Coming Soon” category. Fall is a few weeks from being over and it was clear Tesla wouldn’t be able to make the deadline on many of its stations, especially in the east coast where things have all but stalled in the Supercharger front.

Tesla CEO Elon Musk takes to the Blog to set record straight on fires with 3-step plan

Site default logo image

As reported this weekend, Tesla has announced that it has removed the Air Suspension lowering as part of a three step plan to deal with the media attention. The whole Blog post is worth a read but here are the important bits:

First, we have rolled out an over-the-air update to the air suspension that will result in greater ground clearance at highway speeds. To be clear, this is about reducing the chances of underbody impact damage, not improving safety. The theoretical probability of a fire injury is already vanishingly small and the actual number to date is zero. Another software update expected in January will give the driver direct control of the air suspension ride height transitions.

Second, we have requested that the National Highway Traffic Safety Administration conduct a full investigation as soon as possible into the fire incidents. While we think it is highly unlikely, if something is discovered that would result in a material improvement in occupant fire safety, we will immediately apply that change to new cars and offer it as a free retrofit to all existing cars. Given that the incidence of fires in the Model S is far lower than combustion cars and that there have been no resulting injuries, this did not at first seem like a good use of NHTSA’s time compared to the hundreds of gasoline fire deaths per year that warrant their attention. However, there is a larger issue at stake: if a false perception about the safety of electric cars is allowed to linger, it will delay the advent of sustainable transport and increase the risk of global climate change, with potentially disastrous consequences worldwide. That cannot be allowed to happen.

Third, to reinforce how strongly we feel about the low risk of fire in our cars, we will be amending our warranty policy to cover damage due to a fire, even if due to driver error. Unless a Model S owner actively tries to destroy the car, they are covered. Our goal here is to eliminate any concern about the cost of such an event and ensure that over time the Model S has the lowest insurance cost of any car at our price point. Either our belief in the safety of our car is correct and this is a minor cost or we are wrong, in which case the right thing is for Tesla to bear the cost rather than the car buyer.

TSLA shares are again down in morning pre-market trading.

Tesla 5.8 Firmware Update rolling out to Model S owners just 10 days after 5.6

Site default logo image

Tesla updated my, as well as many other, Model S cars this weekend with the 5.8 firmware.  5.8 doesn’t seem to be a big update from 5.6 that I got just 10 days ago. Some drivers have reported:

* A wipers service mode. Who would’ve know? 🙂
* A reset TPMS button. Nice.
* MAC Address display in Wifi settings. Who was it again asking for this to setup their router’s MAC filter?
+ all the goodies which were already in 5.6, of course.

Also – it seems to accelerate a little smoother all of a sudden but that’s likely just me being overly sensitive.

Atherton, CA town manager would love to see Tesla Model S police cars

Site default logo image

It is a bit of a stretch but interesting note on story about the rich village of Atherton where Teslas are the best-selling car:

“I probably see a Tesla Model S every day,” said Atherton City Manager George Rodericks. “Atherton is 100 percent residential. We don’t have any public charging stations. We don’t even have a grocery store. But driving around town, you sure do see a lot of them. I’d love to see the Model S be used for Atherton’s police cars.”

Best way to catch a tesla is with another Tesla. Doesn’t sound like the town is hurting for money.

Tesla Model S 5.6 Firmware OTA upgrade rolling out to US owners

Site default logo image

I just got my 5.6 firmware update without calling Tesla. I was on 4.5.1 previously. It took about 20 minutes to install after a 2 minute shutdown procedure.  After the update I got the screen above.

I did have some trouble connecting to my home Wifi networks as you can see toward the end there.  I’m going to give it another try tomorrow, I wonder if it isn’t encryption problems. I also want to try a Verizon LTE Mifi.

I really love the updates to maps. Right away I can see the usefulness of the compass and directional UI.

I know 5.6 has been rolling out to Europeans for around a month but I don’t know many folks stateside that have it via OTA without it being pushed for issues.

Also, I hear this update reduces the vampire drain effect. That would be a big deal for me because I lose at least 5 miles per 24 hours unplugged.

Fox begins attack on Tesla Model S with ‘auto expert’ who fans flames of fires to the old and ignorant

Site default logo image

[youtube=http://www.youtube.com/watch?v=fhMjRzvE1Ng]

You knew Fox News was going to stage a takedown of Tesla at one point or another. Here is Lauren Fix’s interview on the Tesla Fires (above).

‘Interviewer’: “…Something about Tesla Cars that cause them to blow up”?  Just … No

Fix: “supposedly a piece of metal that supposedly punctured the battery box” All facts. Seattle fire: Metal into the underside of the battery box at highway speeds. What would happen if it hit a gas tank?

Fix: “NHTSA didn’t investigate”. They did. They found no reason to push forward and the car acted like expected.

“After reviewing all available data, the NHTSA has not found evidence at this time that would indicate the recent battery fire involving a Tesla Model S was the result of a vehicle safety defect or noncompliance with federal safety standards,” the agency said in a statement.

Fix: “I assume they offered him a deal on a new car”. No. Published reports say the Seattle driver happily bought another one with the money he got from his insurance

Fix: “If this were Ford, GM, Toyota…[Congress] they would call them on the carpet and basically and draw and corner them” There are hundreds of vehicle fires every day. I don’t think that Congress acts on every one of them?

Fix “Something happened in a hit a wall but here wall on a regular combustion car your car is not likely to blow up” Actually the car did a lot more than bust through a wall. It was called an extreme accident where the vehicle travelling well over the speed limit experienced a violent crash with low wall after it jumped curb and went airborne. The driver walked away without any permanent injuries.

Fix: “There’s hundreds of people that complain; many many of these owners are happy because they’re environmentalists they want to be cool” There are quite a bit of owners who are speed freaks and who love havin a 7-seat sports car that is quiet and requires no maintenance.  Motor Trend and Consumer reports must be crazy.

Yes, it is a sloppy, stupid takedown but unfortunately there are a lot of ignorant and elderly people who watch Fox and actually consider it to be a source of information. The oil industry is a hundreds of billions of dollars per year industry. These attacks will only grow more prominent in the coming years.

Tesla Model S to appear on Top Gear USA?

Site default logo image

Jeremy Clarkson famously gave the Tesla Roadster some undeserved bad publicity a few years ago. Tesla then sued Top Gear/BBC for libel and eventually dropped the suit. There is no love lost between Tesla CEO Elon Musk and Top Gear’s Jeremy Clarkson however as evidenced by his comments earlier this week (above).

With that in mind, commercials are showing that Top Gear USA will be reviewing the Tesla Model S this week. Will it get a fair shake?

Tesla opens Springfield Oregon Supercharger, announces West Coast Corridor open

Tesla today officially announced the Springfield Oregon Supercharger had opened thereby allowing Tesla owners to travel the whole West Coast of the US without spending a penny.

I had called the thing a bit early last week but Tesla wasn’t ready to give it the green light until the Springfield OR station opened because the distance between the two previous Oregon stations “would be a little bit risky” for 60kWh owners.

The new station is a few blocks off the highway, contains 8 stalls and is open immediately.

Some observations on new Tesla Model X prototype shown at Palo Alto showroom

Site default logo image

[twitter https://twitter.com/teslamotors/status/389440087324246016]

As predicted, Tesla did showcase its Model X SUV-Crossover at its Palo Alto Store today and it differed in a few ways from what we’d seen before.

Perhaps most noticeably, the virtual side rear view windows which worked as cameras (pictured from Tesla’s web page, above) were replaced by Tesla Model S-lookalikes (below). That could indicate that Tesla isn’t going to get government clearance to do away with the side rear view mirrors. Or perhaps Tesla hasn’t yet gotten clearance and needed to put something legal on the road. The cameras were intended to reduce drag that would likely be lost with the added height of the Model X.

Next, the steering wheel appears to have replaced the hardware buttons on the model S with iPod nano like 2-inch touch screens (these aren’t necessarily new, they have been in the Tesla Model X webpage for months). I have mixed emotions about this. The obvious advantage is that Tesla can change what’s on the screen giving them more UI control (especially good when global markets are considered). On the other hand, the steering wheel buttons are the one hardware button on the Model S that you can actually feel and navigate without your eyes, something that is key when driving a car.

Two pictures of the new display steering wheel and the website:

The big question: Can you really fit 7 adults in this thing comfortably? Tesla hasn’t changed the wheelbase nor the overall length of the vehicle so how do they make more room? From the first glance, it appears that those back seats aren’t going to have a lot of legroom.

For kids, this is fine, but saying that 7 normal sized adults can fit in this thing seems a little bit of a …stretch. I really like the ‘jump seat’ model in the Model S which puts 2 kids rear facing seats in the back while leaving plenty of legroom for the now middle compartment.  This model seems to compromise the middle compartment to give room for forward facing rear seats.

Finally, no one saw that mystery app icon (far right, below) on the Model X website did they? It looks like a download option but I’m still not sure what this is for.

The Model X is supposed to go on sale in about one year with similar cost and configurations as the Model S.

2014 Cadillac ELR is a $75K Volt in a nice suit

Site default logo image

[youtube=http://www.youtube.com/watch?v=aEqNniw7Qbs]

Just when you think the big automakers might be catching on to the electric car scene, GM goes and does something absurd like the 2014 Cadillac ELR. Remember the Cadillac Cimarron, the dressed up Chevy Cavalier? This is worse.

Introduced with pricing today and shipments in January, the $75,000 ($68K after Fed Tax Cred) car will have almost identical specs as the Chevy Volt in 35 miles in EV mode and 300miles on gas. That’s actually worse than the Volt’s upgraded 40 EV miles – probably due to the slightly higher performing engine on the Caddy. It even appears to have the same T-shaped battery going through the middle of the car as the Volt which makes it barely capable of seating of 4 people. Trunk space is listed at a comical 10.5 cubic feet which is about a third of the Tesla Model S before you consider the “Frunk”.

The ELR is a two door which probably lends itself better to the 2+2 seating that the 4-door Volt has currently.

As for performance gains, there is no listed horsepower but the 295 lb-ft compares favorably to the 273 lb-ft. torque listed or the Volt. But, as a sad comparison, the sub-$20,000 Chevy Spark 100% electric vehicle produces 400lb-ft of torque so that $75K Caddy is likely going to get smoked by a $20K hatchback with over twice the amount of EV battery made by the same company.

I’m in full agreement with Ed Kim, vice president of industry analysis at AutoPacific Inc., who on Friday tweeted: “A Volt with a Cadillac body and badge for Tesla Model S money? Is GM on crack?”

The Volt is a great car but GM isn’t going to have any kind of success taking it into the Tesla price category without significantly upgrading the batteries and motor and bringing some more innovation to the table. This is embarrassing.

You don’t capitalize that ‘X’ by accident. Tesla’s Model X is a crossover/SUV built on the Model S frame with more headroom, gull falcon wing doors in the rear and room for 7 or 8 adults.

Tesla pushed the rollout of the X back to focus on meeting Model S supply but the product is due next year and can be reserved for $5000-$40,000.

Update: We’ve heard that the invite to the store says: “Come by to experience Model S and to see the Model X Design Prototype on display all weekend.”

Elon Musk talks about the Tesla Model S’s safety; Battery fire was statistical inevitability

Site default logo image

[youtube=http://www.youtube.com/watch?v=8n-xsEjq7pk&start=1380]

As the world loses its mind over the Tesla that caught on fire, it is important to note a few things. Above, from a conversation in July with owners and stockholders Musk indicates some of the pretty incredible considerations that went into building the Model S.

Last month, when announcing the best NHTSA ratings ever, Tesla expanded on Musk’s statement above –that statistically there was likely to be a battery fire.

The Model S lithium-ion battery did not catch fire at any time before, during or after the NHTSA testing. It is worth mentioning that no production Tesla lithium-ion battery has ever caught fire in the Model S or Roadster, despite several high speed impacts. While this is statistically unlikely to remain the case long term, Tesla is unaware of any Model S or Roadster occupant fatalities in any car ever.

The Seattle driver was fine so, as of as of this writing, no one has yet had a permanent injury or death from a Tesla Model S accident.

By the time the low-cost Tesla is released, Supercharging might only take 5-10 minutes

Site default logo image

In an interview with MIT Technology Review, Tesla CTO JB Straubel says that battery charging technology is going to get even quicker than it is now.

“It’s not going to happen in a year from now. It’s going to be hard. But I think we can get down to five to 10 minutes,” Straubel said in an interview with MIT Technology Review. He noted that the current superchargers, which deliver 120 kilowatts of electricity, “seemed pretty crazy even 10 years ago.” Conventional public charging stations deliver well under 10 kilowatts.

Tesla has already reduced its Supercharger times in half going from 40 minutes to 20 minutes for a half charge. A few more ‘half times over the next few years and we’ll be there. One of the barriers of this type of charging is heat so this might involve external or internal cooling for battery charging.

One challenge of fast charging is that delivering power to a battery very rapidly can cause it to overheat. To avoid damaging the battery, the outside charger needs to communicate with the electronics that monitor the state of the batteries, including their voltage and temperature, and quickly adjust charging rates accordingly. “To do that kind of charging, everything has to be designed and working in perfect synchrony,” Straubel says.

Achieving five-minute charges will require not only further improving the charging system, but also improving the interface with the electrical grid. As it is, only some places on the grid can handle 120-kilowatt charging. Drawing large amounts of power from the grid also incurs demand charges from the utility, increasing the cost of the system.

But Straubel says that Tesla plans to get around these problems by equipping supercharging stations with solar panels and batteries.

The rest of the interview is here and worth a read.

Tesla Model S firmware update 5.0 brings the Wifi and better sleep, creep and towing modes

Site default logo image

Click to enlarge

Tesla owners should be receiving a pretty huge over the air update in the coming days which will enable a bunch of new functionality in the car. A Flickr user has updated the release notes. The biggie here is Wifi which allows the Tesla to connect to either a stationary wifi access point or tether to a mobile phone that may have a better signal than the HSPA network the Tesla attaches itself to.

Other new features include: Tow Mode, which allows you to put your car in neutral (wonder if this works in automatic car washes?), Auto screen clearing mode and accessing radio presets from the steering wheel.

Model S owners will also see improvements in Maps, Creep mode performance, additional driver profiles and another biggie: Improved power management when not in use.

The last one is huge because the Model S burns about 5 miles of charge per day in sleep mode, otherwise known as “Vampire mode”. Taking off a chunk of that will help it last a long time in storage without a recharge and stop the useless power drain.
