dmoberhaus writes: Someone claimed to use their Tesla to power a cryptocurrency mine to take advantage of the free energy given to Tesla owners. But even with free energy, does this scheme make sense? Motherboard ran the numbers.

From the report: "...If we assume that each of the GPUs in this rig draws around 150 watts, then the 16 GPUs have a total power draw of 2.4 kilowatts per hour or 57.6 kilowatt hours per day if they ran for a full 24 hours. According to Green Car Reports, a Tesla Model S gets about 3 miles per kilowatt hour, meaning that running this mining rig for a full day is the equivalent of driving nearly 173 miles in the Tesla. According to the Federal Highway Administration, the average American drives around 260 miles a week. In other words, running this cryptocurrency mine out of the trunk of a Tesla for a day and a half would use as much energy as driving that Tesla for a full week, on average. Moreover, drivers who are not a part of Tesla's unlimited free energy program are limited to 400 kilowatt hours of free electricity per year, meaning they could only run their rig for a little over 7 days on free energy.

Okay, but how about the cost? Let's assume that this person is mining Ethereum with their GPUs. Out of the box, an average GPU can do about 20 megahashes per second on the Ethereum network (that is, performing a math problem known as hashing 20 million times per second). This Tesla rig, then, would have a total hashrate of about 320 megahashes. According to the Cryptocompare profitability calculator, if the Tesla rig was used to mine Ethereum using free electricity, it would result in about .05 Ether per day -- equivalent to nearly $23, going by current prices at the time of writing. In a month, this would result in $675 in profit, or about the monthly lease for a Tesla Model S. So the Tesla would pay for itself, assuming the owner never drove it or used it for anything other than mining Ethereum, Ethereum doesn't drop in value below $450, and the Tesla owner gets all of their energy for free." Motherboard also notes that this conclusion "doesn't take into account the price of each of the mining rigs, which likely cost about $1,000 each, depending on the quality of the GPUs used." TL;DR: Mining cryptocurrency out of your electric car is not worth it.

An anonymous reader writes: Tesla will soon offer a 100 kWh battery for the Model S and Model X that will allow for increased range -- perhaps as much as 380 miles for the Model S. Currently, the 90 kWh batteries are the company's largest capacity. Kenteken.TV is reporting that the Dutch regulator that certifies Tesla's vehicles for use in the European Union, RDW, has recently published a number of new Tesla variants. RDW's public database now includes entries for a Tesla "100D" and "100X," which are titles that follow Tesla's current naming system based on battery capacity. The listing for the 100D claims the vehicle has a range of 381 miles or 613 kilometers. The motor output is reported as 90 kilowatts (121 horsepower), which is the maximum output the Tesla motors can sustain without overheating. Autoblog notes that EU range estimates tend to be more optimistic than those issued by the U.S. EPA. A more realistic range might be 310 to 320 miles.

One computer wiz claims to have hacked into Tesla's firmware and discovered a reference to a juicier battery. Self-proclaimed white hat hacker, Jason Hughes, says he discovered a secret in Tesla's firmware 7.1, but he didn't want to tell the world outright what he discovered, so he made Tesla Motors Club forum-members work for it by obfuscating the secret with a hash. TheSHA256 hash, a one-way function, would either require forum members to guess and check to decrypt this code, or to look it up in a hash directory. Forum member LuckyLuke decrypted Hughes' hash and discovered its meaning: P100D. P100D is the nickname given to Tesla's upcoming 100-kWh battery pack that would give the Model S a range of 300 miles or more. In response to a fellow forum-member decrypting his secret code, Hughes responded on Twitter. On the forum, Hughes had some additional information to mention, saying: There have been references to the P100D in firmwares as early as 2 months ago. They finally added the badges to 2.13.77. I mucked it up a bit by adding a crappy background (it's a PNG with transparency in the firmware)... There are quite a few things that are in the firmware that I'm not prepared to share publicly. Just like the P100D has been in there for months with my lips mostly sealed. I don't want to spoil all of Tesla's surprises.

HughPickens.com writes: Matt Richtel writes in the NYT that one big reason there are only about 330,000 electric vehicles on the road is that car dealers show little enthusiasm for putting consumers into electric cars. Industry insiders say that electric vehicles do not offer dealers the same profits as gas-powered cars, they take more time to sell because of the explaining required, and electric vehicles may require less maintenance, undermining the biggest source of dealer profits — their service departments. Some electric car buyers have said they felt as if they were the ones doing the selling. Chelsea Dell made an appointment to test-drive a used Volt but when she arrived, she said, a salesman told her that the car hadn't been washed, and that he had instead readied a less expensive, gas-powered car. "I was ready to pull the trigger, and they were trying to muscle me into a Chevy Sonic," says Dell. "The thing I was baffled at was that the Volt was a lot more expensive." Marc Deutsch, Nissan's business development manager for electric vehicles says some salespeople just can't rationalize the time it takes to sell the cars. A salesperson "can sell two gas burners in less than it takes to sell a Leaf," Deutsch says. "It's a lot of work for a little pay."

Jared Allen says that service is crucial to dealer profits and that dealers didn't want to push consumers into electric cars that might make them less inclined to return for service. Maybe that helps explains the experience of Robert Kast, who last year leased a Volkswagen e-Golf from a local dealer. He said the salesman offered him a $15-per-month maintenance package that included service for oil changes, belt repair and water pumps. "I said: 'You know it doesn't have any of those things,'" Mr. Kast recalled. He said the salesman excused himself to go confirm this with his manager. Of the whole experience, Mr. Kast, 61, said: "I knew a whole lot more about the car than anyone in the building." "Until selling a plug-in electric car is as quick and easy as selling any other vehicle that nets the dealer the same profit, many dealers will avoid them, for very logical and understandable reasons," says John Voelker. "That means that the appropriate question should be directed to makers of electric cars: What are you doing to make selling electric cars as profitable and painless for your dealers as selling gasoline or diesel vehicles?"

cartechboy writes: Last Friday we learned that Volkswagen got caught cheating on emissions testing via software programming. The punishment? It could get slapped with up to $18 billion in fines. While the company has yet to admit to any wrong doing, the CEO has now issued a formal apology and said the automaker will cooperate fully with any and all investigations. It's issued a stop-sale on all new and used TDI vehicles until further notice. VW's currently in talks with the EPA and the California Air Resources Board in regards to these allegations. It's also ordered an external investigation of its own into the matter. Whether criminal charges will be filed is yet to be seen.

cartechboy writes: First, it was Chrysler last month with its Uconnect system being hacked while being driven down the road. Now, it's Tesla's turn. That's right, the Silicon Valley automaker's very own Model S electric car has been hacked by two white-hat hackers. The duo were able to manipulate the speedometer, lock and unlock the car, and at speeds of less than 5 mph they were able to make all the electronics go blank and shut down the car while engaging the emergency parking brake dragging the car to a stop. Tesla's already issued a software update that owners can download to path the security flaw. Welcome to the new world where cars can be hacked thanks to all their electronics.

cartechboy writes: It's like a game of follow the leader. First, Tesla announced its Powerwall Batteries, and now Mercedes-Benz plans to follow suit by entering the energy-storage business as well. A division of parent company Daimler has been testing battery packs that can power houses, and plans to launch commercially in September. Supposedly a battery pack for "light industrial, commercial, and private" use is being tested with sizes ranging from 2.5 kWh to 5.9 kWh. While Tesla's building a massive Gigafactory to make all its batteries for its Powerwall and electric cars, it's unclear exactly how Daimler plans to produce its batteries in a larger-scale energy-storage operation.

cartechboy writes: Remember 18 months ago when Tesla promised it was going to launch battery-swap stations? Well, it's finally happening, sort of. It seems Tesla's about to announce a battery-swap pilot program that will launch next week. The swap site will be located across the street from a Tesla Supercharger site in Harris Ranch, California — 184 miles south of San Francisco and about 200 miles north of Los Angeles. The pilot program will involve an unspecified number of Model S electric-car owners, who will be invited to take part in the test. For now, the battery-swap service will be offered by appointment only, at a cost of roughly a tank of gas in a premium sedan. Tesla's using words to describe this pilot program like "exploratory work" and "intended to test technology and assess demand" for a swapping service. While originally pitched that the battery swap would take less time than it would to take to refill the gas tank of a comparable luxury sedan, the company says now that "for this specific iteration" the swap process will take "approximately 3 minutes" — though it adds Tesla has "the ability to improve that time with future iterations." Is this test going to show that battery swapping is or isn't a realistic initiative?

cartechboy writes The common assumption among Tesla fans seems to be that state auto-dealer lobbyists are working with Republican legislators to enact laws banning direct sales of Tesla's electric cars to retail buyers. Is it true? The New York Times published an article with some data points that assesses the supposition. While the article mainly focuses on the conflict between Uber and the Republican party, some quotes could be easily applied to Tesla. For instance, Republican National Committee chairman Reince Preibus said, "It should be consumers, not government bureaucrats or legislators, that deicde what companies get our business." The author of the article, Josh Barro, wrote that 22 states permit direct sales of automobiles by Tesla to retail buyers, and of those the majority--14 of them-- voted for President Obama. He suggested that Democratic California, Illinois, and New York "have freer markets in auto retailing than Texas," which is presently Republican. When looking at a five-year-old article by Nate Silver that looked at political donations by car dealers, fully 88 percent of those donations went to Republican candidates, and just 12 percent to Democrats. That possibly suggests a propensity among Republican state legislators to support the interests for car dealers over those of electric-car buyers. Is the small bit of evidence enough to make a case? Good background on the current system of dealership sinecure can be found in this short 2009 Competition Advocacy Paper from the U.S. Department of Justice, which delves into the history and effects of the dealers-only system which still prevails.

cartechboy writes It's a story we've come to see quite often: a state trying to ban Tesla's direct sales model. It seems something sneaky just happened in Michigan where Tesla sales are about to be banned. Bill HB 5606 originally intended to offer added protection to franchised dealers and consumers from price gouging by carmakers, and was passed by the Michigan House in September without any anti-Tesla language. However, once it hit the Senate wording was changed that might imply the legality of a manufacturer-owned dealership was removed. The modified bill was passed unanimously by the Senate on October 2, and then sent back to the House that day where it passed with only a single dissenting vote. The bill was modified without any opportunity for public comment. Michigan Governor Rick Snyder has less than a week to sign the bill into law. Of course, Tesla's already fighting this legislation.

cartechboy writes Most luxury automakers have a Certified Previously Owned (CPO) program. Tesla isn't like a normal luxury automakers, in fact, it's not really like any automaker out there. It doesn't have franchises and it sells its own vehicles through its network of galleries. Now, it plans to create its own CPO program. There are a great deal of Model S sedans out there currently under lease contracts. When those cars are ready to come back, Tesla has guaranteed that it will purchase them for a figure that falls somewhere between 43 and 50 percent of the original purchase price. This is exactly how Tesla's going to create its CPO fleet. Tesla seems to do everything in an unconventional manner, so we'll have to see if its CPO program behaves like every other automaker's, or if it's different somehow as well.

cartechboy writes There's been plenty of skepticism when it comes to Tesla. The Silicon Valley startup unveiled an all-electric car that stunned the world and had many other automakers rolling their eyes. Fast forward to 2014 and Tesla's preparing to launch its third model, the Model X. Production of the Model S sedan is humming along, and this new automaker continues to make headlines multiple times a week. Industry veteran Bob Lutz was the champion behind the Chevrolet Volt, and has been quite vocal about Tesla from the beginning. So what's his view on the company now? He said Tesla will remain a "fringe brand" until it launches its next generation of vehicles and the smaller, less expensive Model 3. Speaking Wednesday on CNBC's "Squawk Alley" finance show he said that Tesla's stock price was "kinda high" at the moment.

cartechboy writes Unless you've been in a coma for a while you're aware that many dealer associations have been causing headaches for Tesla in multiple states. The reason? They are scared. Tesla's new, different, and shaking up the ridiculously old way of doing things. But the thing is, Tesla keeps winning. Now Ward's commenter Jim Ziegler, president of Ziegler Supersystems in Atlanta, wrote an opinion piece that basically says Tesla's going to prevail in every state against dealer lawsuits. He says Tesla's basically busy defending what are nuisance suits. This leads to the question of whether there will be some sort of sweeping federal action in Tesla's favor.

cartechboy writes How low can battery costs go, and how fast? That's the question automakers are dealing with when it comes to the future of electric cars. Tesla is betting big on electric and has already proven many skeptics wrong with its Model S sedan. The company is making even bolder claims with its upcoming Model 3 stating it'll have about 200 miles of range and a base price of $35,000. That's a nice goal, but is it possible. Battery skeptic Menahem Anderman wrote a new report suggesting that the pace of cost reduction for electric car batteries won't be as swift as Tesla's CEO Elon Musk suggests. This leads Anderman to predict the actual price of the upcoming Model 3 will be in the range of $50,000-$80,000.

cartechboy writes: Tesla and Toyota have already worked together a few times. The factory in which Tesla builds the electric Model S? It bought that from Toyota. The Toyota RAV4 EV? The battery and software tuning was done by Tesla. Now it sounds like Tesla and Toyota might have another significant project in the pipeline in the next two or three years. Tesla CEO Musk said such a project could be "on a much higher volume level" than the firm's last project with Toyota, the RAV4 EV. Toyota currently has a 2.4 percent stake in Tesla Motors and has sold 2,130 RAV4 EVs through August. For its part, Toyota has no comment regarding Musk's statements about the future project. Given Toyota's stance on electric cars, Musk's comment is a bit confusing. So what exactly will this joint project be?

cartechboy writes Tesla's Superchargers are the talk of the electric car community. These charging stations can take a Model S battery pack from nearly empty to about 150 miles of range in around 30 minutes. That's crazy fast, and it's nothing short of impressive. But what does it take to actually build a Tesla Supercharger site? Apparently a lot of digging. A massive trench is created to run high-capacity electric cables before the charging stations themselves are even installed. A diagram and photos of the Electric Conduit Construction build out have surfaced on the Internet. The conduits connect the charging stations to a power distribution center, which in turn is connected to a transformer that provides the power for charging cars. It took 11 days to install the six charging stalls in Goodland, Kansas. If you thought it was a quick process to build a Supercharger station, you were clearly wrong.

cartechboy writes: We all know Tesla is working on its Gigafactory, and it has yet to announce officially where it will be. But the automaker did announce a shortlist of possible locations, and California wasn't on it. The state has quickly been trying to lure Tesla to get back into contention. Now the state may waive environmental rules which would normally make construction of such a large manufacturing facility more difficult. Apparently, Governor Jerry Brown's office is currently negotiating an incentive package for Tesla that would waive certain parts of the nearly half-century-old California Environmental Quality Act. Not only that, but state officials are reportedly considering letting Tesla begin construction and perform damage mitigation later, along with limiting lawsuits that could slow down the project. Let's not forget some massive tax breaks, to the tune of $500 million. Is California stepping out of bounds here?

cartechboy writes Remember four years ago when Tesla's new headquarters in Palo Alto, California seemed like a big risk? Yeah, time flies and now the Silicon Valley startup is already running out of room. Apparently the electric-car maker is already looking for 200,000-300,000 square feet of office space in the lower Peninsula market. Part of the motivation is that the company would like to have employees closer to its Fremont factory, which is 20 miles from its current headquarters. With heavy traffic that journey can take up to an hour or more. While not looking to relocate its headquarters, Tesla's simply looking to expand its space. Meanwhile, we all eagerly await to hear if the Gigafactory will indeed end up being built in Nevada.

cartechboy (2660665) writes "Earlier in the week we heard that Tesla and Panasonic had reached an agreement to build the gigafactory together, and today that became official. Now it seems that things are farther along than anyone thought. In fact, construction of the plant might already be secretly underway in Nevada. This is of course interesting as Tesla hasn't officially announced where the gigafactory will be built. Something called Project Tiger is currently underway east of Reno, and there's a lot of construction workers, heavy equipment, and a heavily guarded fenced barrier around the site. The volume of dirt being moved is 140,000 cubic yards, which matches the gigafactory dimensions given earlier this year by Tesla. Is it possible that Tesla's actually building the gigafactory before even announcing its location? It seems so, yes."

While the electronics giant was originally skeptical of Tesla's battery factory, it now isn't just on board, it's actually going to participate in the construction of this new facility. It's reported that Panasonic will invest 20 billion to 30 billion yen (194 million to $291 million at current exchange rates), and supply fabrication machinery necessary for cell production. That means Pansonic could end up footing the bill for $1 billion of the total $5 billion anticipated investment required for the gigafactory to get off the ground. If things continue to move forward, the Gigafactory should be online by the end of 2017.

cartechboy (2660665) writes The Toyota Prius is pretty darn popular, especially in California. One might think that hybrid sales are on the rise as gas prices continue to fluctuate, but it seems hybrid sales in the U.S. might be peaking. Researchers at IHS Automotive found that U.S. hybrid sales haven't kept pace with the rest of the market. In the automotive world, conventional wisdom states that adding a model to a brand or segment will increase sales--but that hasn't happened with hybrids. The number of hybrid offerings has almost doubled from 24 in 2009 to 47 in 2014--but U.S. hybrid sales haven't dramatically increased. In fact, hybrid market share actually declined from 2009 to 2010, and then again from 2013 to 2014. So if consumers aren't buying hybrids, what are they buying? It seems some hybrid early adopters are now switching to plug-in hybrids or electric cars stating that these models are just nicer to drive.

cartechboy (2660665) writes "Tesla won't reveal its production figures every quarter, but it has now likely built about 50,000 all-electric Model S luxury sport sedans. Unlike other automakers, Tesla doesn't group its changes to a model year, rather it makes running changes to cars whenever updates are tested, validated, and ready to roll out. Which raises the question, are model year 2012 Model S sedans already outdated? The answer is it depends how you look at it. From a powertrain perspective, no. There are still two battery-size options and the shape is still the same. But under the surface of the car there are a surprising number of updates and new options. Not including software changes (of which there are dozens already pushed to the car), changes range from power folding mirrors and a new cold-weather package (which cannot be retrofitted) to a new ultra-high-fidelity sound package and three-zone, three-mode rear seat heaters. It's worth noting that none of these are mandatory changes — there are merely options that have been added to the roster of available equipment."

cartechboy writes: "Automakers are scrambling to increase vehicle fuel economy every year as regulations increase, so when an automaker finds a way to possibly increase fuel economy by 10 percent with one new part, that gets some attention. Today that automaker is Toyota, and the part is a new semiconductor. Toyota's power control units (PCU) in its hybrids use semiconductors to govern the flow of electricity between the battery and the electric motor. Unfortunately, they're also an electrically restrictive component. Toyota says the PCU accounts for a quarter of the total electrical power losses in a hybrid drive system, and semiconductors alone make up a full fifth of the total. Reduce electrical losses through a semiconductor, and you can make your hybrid system (and therefore your car) more efficient. Toyota has done this, in theory at least, using a new silicon carbide material for its semiconductors, rather than a standard silicon unit. The future could be shaped by individual parts, and this new semiconductor tech is one piece of that puzzle."

cartechboy writes: "Tesla seems to be doing quite well these days, but one bond trader thinks the company should quit making electric cars and focus efforts on making batteries instead. Bond manager Jeffrey Gundlach says he's already tried to meet with Elon Musk to persuade him to take the battery-only route. Speaking to Bloomberg, he said Tesla could be 'wildly transformational' in the same way electricity and electromagnets were at the advent of their discovery. Enough people are interested in Tesla's vehicles that Musk probably won't take Gundlach's advice. Should he?"

That partnership gave us the RAV4 EV electric crossover, but it seems as though that will be the only vehicle we see from that deal. The partnership will soon expire and Toyota has no plans to renew it. Why? Because Toyota believes the future is in hydrogen fuel cell cars, not battery electric vehicles. We knew trouble was brewing when the RAV4 EV failed to set the world on fire when it came to the sales floor. Then Toyota and Honda announced plans to debut hydrogen fuel cell vehicles as early as next year. Add it all together and the writing was on the wall. Is Toyota right? Are hydrogen fuel cell cars the future, or is it missing the mark?"

joe5 writes "Many experts suggest that battery technology is really the key to the future of transportation. Its certainly the key to unlocking Tesla for even further growth. Today, a Japanese startup called Power Japan Plus unveiled a new battery chemistry that could significantly improve transportation batteries. In testing, the recycle-able cell has completed more than 3,000 charge/discharge cycles with virtually no performance degradation, meaning that it could conceivably last the lifetime of a car. They company won't yet provide too many details due to pending patents, and won't even say who its first customer is — but the chemistry requires 'specific and proprietary changes to the nanostructure of the carbon crystals.'"

BMW has just revealed a concept carport that takes these structures into the future. Made out of bamboo and carbon fiber, this concept carport features solar panels that harvest the sun's energy and use it to charge your BMW i-vehicle. "With the solar carport concept we opted for a holistic approach: not only is the vehicle itself sustainable, but so is its energy supply," explained Tom Allemann of BMW Designworks USA. "This is therefore an entirely new generation of carports that allows energy to be produced in a simple and transparent way. It renders the overarching theme of lightweight design both visible and palpable." The entire thing is quite beautiful, and could be the way to make not only charging your electric car sustainable, but also building your carport."

cartechboy (2660665) writes "Tesla just announced its first-quarter earnings and the numbers are interesting. It logged revenue of $713 million on deliveries of 6,457 Model S electric cars. It's worth noting that's basically the number of vehicles it said it would sell in the quarter, but that number is slightly down from the prior quarter. It built a total of 7,535 Model S cars in the quarter as it built inventory as shipments began to China where sales just started last month. Net orders in North America grew 10 percent, and production for the second quarter is expected to increase to 8,500-9,000 Model S cars. Tesla expects to deliver 35,000 cars during the 2014 calendar year. Musk told analysts that China's enthusiastic and that government support is crucial. The Model X is delayed until spring of 2015 with production-design prototypes being ready in the fourth quarter. Tesla hopes to possibly break ground as early as next month on its gigafactory, though the location has yet to be announced. Of course, the stock market is already reacting to these numbers and is currently down nearly 3 percent in after hours trading."

cartechboy (2660665) writes "You think of efficient electric car and you probably think of the Tesla Model S, right? Well, you'd be wrong as the Model S is only rated at 89 MPGe. As of today, BMW now has the most efficient electric car sold in the U.S., the 2014 i3. The ratings were just posted to the Internet via a window sticker, and at 124 MPGe combined (138 MPGe city, 111 MPGe highway), the i3 is currently king of the efficiency race. The nearest competitor? The 2013 Scion iQ-EV with a 38 mile range and 121 MPGe rating, but it's not even available to the general public. Other competitors are mostly compliance cars such as the Chevrolet Spark EV and Fiat 500e. So where does that leave us? Well, BMW just won the race, for now. But how long until a competitor takes away that top spot?"

Now auto engineers are working to refine combustion power as part of cars that are increasingly electrified, including plug-in hybrids. Toyota's new 'Free Piston Engine Linear Generator' (or FPEG) shows us one potential way. Linear engines eliminate the rotating crankshaft of conventional engines in favor of a single chamber, in which a piston moves forward and backward. A linear engine has no crankshaft, nor connecting rods. In their place is a gas-filled chamber, the compression of which functions like a spring — returning the piston after the expansion / combustion phases of a typical combustion cycle. This back-and-forth motion can be turned into energy, when you haven't got a crankshaft and the mechanically-useful rotation it produces. While linear engines are far from new, and Toyota's test units are only 10 kW (13 horsepower), a pair of them can still produce enough electricity for a Yaris- or Corolla-sized vehicle to cruise on the highway at 75 mph."

cartechboy (2660665) writes "We've all read about Tesla and the ongoing battles its having with different dealer associations. Basically, dealer associations aren't too pleased about the Silicon Valley startup's direct sales model. Today the FTC has had made a statement on the matter and it's actually in favor of Tesla's direct sales model. 'In this case and others, many state and local regulators have eliminated the direct purchasing option for consumers, by taking steps to protect existing middlemen from new competition. We believe this is bad policy for a number of reasons,' wrote Andy Gavil, Debbie Feinstein, and Marty Gaynor in the FTC's 'Who decides how consumers should shop?' posting to the Competition Matters blog. The FTC appears to take issue not with those laws, but with how they're being used, and with the direct-sales bans being passed in several states. Now the only real question is how long will it be before Tesla prevails in all states?"

cartechboy (2660665) writes "Ask most people why they won't consider an electric car, and they talk about range anxiety. And I can easily imagine why 84 miles of range isn't enough. Now it sounds like Nissan is listening, as well as watching Tesla's success. The company plans to boost the Leaf electric car's driving range with options for larger battery packs. Not long ago Nissan surveyed Tesla Model S owners, and they probably heard loud and clear that longer driving range is very, very important. So it looks like the Leaf might get up to 150 miles of range, possibly by the 2016 model year. The range increase will come from a larger battery pack, possibly 36 or 42 kWh, and more energy-dense cells. Either way, clearly Nissan is looking to expand the appeal of the world's best-selling electric car, and increasing its driving range is pretty clearly a key to doing so. I just wish Nissan would ditch the weird styling while they're at it."

cartechboy (2660665) writes "Led by Tesla, electric cars are all the rage now. And the idea of a nine-passenger all-electric vehicle sounds good--until you learn that it maxes out at 30 mph, weighs almost four tons, and costs in the six figures. What is this monstrosity? It's the Frankenstein creation of a group of animal-rights advocates, who are proposing it as the replacement for New York City's fabled horse carriages--and who paid $450,000 to have a prototype built. Who's against it? Would you believe Liam Neeson and one of NYC's daily papers? The huge electric car--modeled after an early 1900s open touring car, complete with brass lanterns--is on display this week at the New York Auto Show, and it's certainly attracting its share of attention."

cartechboy (2660665) writes "They say you shouldn't bite the hand that feeds you. Maybe it should go you shouldn't trash talk the company you partner with. U.S. head of Mercedes-Benz Steve Cannon was just quoted as saying future service of Tesla's vehicles could be 'limited,' and that while it's great, the market could be more attracted to other luxury automakers once their products hit the market. Cannon also suggests that the current infrastructure isn't up to maintaining and fueling electric vehicles, in particularly Tesla's stores and go-to servicing can't handle high demands. Naturally he said Mercedes has the 'whole network' to put customers minds' at ease. Sounds like fighting words to me. Hey Mercedes, where's your Model S competitor?" There is a reason that Jim Rogers drove around the world in a Mercedes.

cartechboy (2660665) writes "Tesla said a few weeks ago it would add additional safety shielding to protect the battery of every Model S car on the road against damage from road debris. But it offered no photos of its update as it would look when installed--so one owner took his own. These may be the first detail shots of what the three different pieces look like. There's a half-round aluminum tube, a titanium plate, and a T-shaped section--and you can see how they combine to deflect and direct impacts to minimize damage to the battery. Do these updates look like they'll solve Tesla's problems?"

cartechboy (2660665) writes "Let's be real, the three Detroit automakers were skeptical of Tesla Motors, and rightfully so. But at this point, it's pretty hard to deny the impact this Silicon Valley automaker is having on the industry. Now there's a new question buzzing around: Is Tesla Motors actually a carmaker, or is it really just a grid-storage company? If you think about it, the company's stock price is too high for Toyota or Daimler to just buy it outright. So maybe Tesla's gigafactory will not only make batteries for its own electric cars, but it could also sell battery packs to electric utilities and others. In reality, the gigafactory could become its own separate company and just sell the battery packs to Tesla, and others."

cartechboy (2660665) writes "Did you watch the Tesla 60 Minutes segment the other night? If you did, you might have ended up on the floor rolling around laughing like I did. Since when does the Tesla Model S electric car make audible engine noises? Or downshift? Turns out, 60 Minutes dubbed engine noises and a downshift over the Model S running footage. The show claims it was an editing error. Call it what you want, it was absolutely hilarious. A little note to TV producers assigned to cover Tesla Motors in the future: Electric cars don't upshift or downshift." At least they didn't fraudulently blow it up!

cartechboy (2660665) writes "Just the other day we read about how the Department of Transportation will require all manufacturers to include rearview cameras on all new cars produced after May 1, 2018. But there's something else auto manufacturers are pushing for, the ability to replace sideview mirrors with cameras in 2018. Tesla in particular is pushing for this to happen as traditional mirrors are bulky, and not very aerodynamic. That lump of plastic can cause surprising amounts of drag on an otherwise smooth car body. Camera units are much smaller and can be made streamlined, or even mounted nearly flush with the body, thus reducing aerodynamic drag. The idea has been around since the 1990s, and many concept cars have used cameras instead of sideview mirrors for years. But how will NHTSA respond? Is it finally time to ditch the sideview mirror?"
