Silly dyno, that Tesla doesn't have 2,000 lb-ft of torque

Mon, 11 Aug 2014

Torque. Lots of torque, right off the line. That one benefit presented by an electric motor over its internal-combustion sibling, and the Tesla Model S delivers it in spades. 443 spades, to be precise, or about as much as a Bentley Continental GT or McLaren 12C. But when one Emmanuel Chang put his electric sedan on a dyno up (way up north) in Edmonton, Alberta, it registered a whopping 2,000 pound-feet!
Of course that number isn't correct, as no car on the road produces that much torque. Even a Bugatti Veyron produces "only" 1,000 lb-ft, give or take. Clearly something's amiss here, but the problem the dyno had in reading the Tesla's torque apparently doesn't come down to its electric powertrain. (Nor does it have anything to do with the northerly latitude or the interference of polar winds.) It comes down to the shiny, ten-spoke alloys.
Apparently this type of dyno measures torque by running horsepower and wheel revolutions through an algorithm. It measures horsepower at the wheel (which, at 436 hp, wasn't far off of Tesla's own rating of 416 hp) and uses a stationary optical sensor interfacing with a reflector on the wheel. Every time the reflector passes the sensor, it counts one revolution. But since the Model S has shiny ten-spoke wheels (and we presume because it was taken outdoors under bright sunlight), the sensor thought that each passing spoke was one revolution of the wheel... when it was, in fact, ten times too much.

Recharge Wrap-up: Formula E car swap video, Lyft adds carpooling, new Tesla book

Fri, Aug 8 2014

Curious to see how the Formula E car swap goes down? During each hour-long race (or ePrix, as the series calls them), drivers have to make a pit stop to switch cars as the battery runs down. Of course, they want to do it as quickly as possible. It's kind of a tricky dance extricating oneself from the cockpit of one car and slipping into the seat of another facing the opposite direction. See the maneuver in the video below and read more at Jalopnik. A new report forecasts that the CNG and LPG vehicle market will be worth nearly $5.2 billion by 2019. The report cites fluctuating gasoline and diesel prices, and the relatively low prices of these alternative fuels, for their growing popularity. The report also breaks down the popularity of natural gas and propane vehicles in different parts up the world. In the Asia-Pacific region, China is the largest consumer. In Europe, CNG thrives in Italy, while LPG is most popular in Turkey and Poland. Meanwhile, CNG remains a tough sell in America, while South America has a healthy market. Learn more in the press release below or at Markets and Markets. The Ports of Los Angeles and Long Beach are testing trucks connected to overhead electric wires to reduce emissions and improve air quality. The eHighway, as the project is called, will cost $13.5 million and will use battery electric and hybrid trucks to move cargo around the ports along a one-mile stretch of wires. The trucks, made by Siemens and Volvo, also have the ability to disconnect from the wires and drive under their own power. See more in the video below or read more at ABC7. Lyft is introducing its own carpooling feature to its car-hailing app. Yesterday, we reported that its competitor Uber is testing UberPool, and Lyft is now doing something similar to encourage people to share rides. Lyft Line offers discounted rides, and matches passengers who are going to nearby destinations around the same time. Lyft Line offers passengers a guaranteed price before they accept the ride. Lyft is launching the carpooling service in San Francisco, and hopes to expand it from there. Read the in-depth article at The New York Times. A new book is available called Tesla Motors: How Elon Musk and Company Made Electric Cars Cool, and Sparked the Next Tech Revolution. Written by Charles Morris, senior editor of Charged, it chronicles the history of the famed electric automaker, its achievements in business and technology and the people responsible for Tesla's success.

Recharge Wrap-up: Tesla seeks Gigafactory architect, Uber hails carpools

Thu, Aug 7 2014

Tesla is looking for an architect to help design its proposed Gigafactory battery manufacturing facility. According to the Palo Alto-based job listing, which is titled "Architect - Gigafactory," the applicant must have, among other qualifications, over five years of experience with "high-tech infrastructure and operational facilities (semiconductor, solar, battery, waste water treatment plants, etc.)." The job also includes being away from home quite a bit, as it the listing states, "This full time role requires the flexibility of traveling when needed (up to 70 percent) and doing whatever it takes to achieve project objectives." Think you've got what it takes? See the listing for yourself, here, or read more at Silicon Valley Business Journal. Tesla has appointed Robyn Denholm of Juniper Networks to its board of directors. Denholm is Executive Vice President, Chief Financial and Operations Officer at Juniper Networks. Denholm replaces Brad Buss as chair of Tesla's Audit Committee and a member of the company's Compensation and Nominating and Corporate Governance committees. Buss will remain a member of Tesla's board as he joins SolarCity as CFO. Denholm is Tesla's first female director. Read more at Bloomberg, or in the press release below. Uber, the company behind the now famous ride-hailing app, is introducing its carpooling service, UberPool. The service matches drivers with (hopefully multiple) passengers going to similar destinations, with users paying just a fraction of the cost of a normal taxi, or even an Uber ride. If a rider can't get matched with a driver, they can enjoy a discounted Uber ride. As the company points out in its blog, "At these price points, Uber really is cost-competitive with owning a car, which is a game-changer for consumers." UberPool is currently running a private beta program, which it plans to expand on August 15. Read more in-depth about the UberPool at Forbes, or learn more at Uber's blog. For a few reasons why this new expansion might run afoul of archaic laws (put there to keep entrenched interests in play), check out Engadget. Plug-in hybrids are encouraging an evolution of transmission technology. Companies like Schaeffler and ZF Friedrichshafen are adapting their transmissions to include electric motors within them for use in plug-in hybrids. For example, the electric motor in ZF's eight-speed powers the transmission when the internal combustion engine is shut off.

Tesla trademark suit in China ends with settlement

Wed, 06 Aug 2014

After years of fighting, Tesla has finally put its trademark dispute in China with businessman Zhan Baosheng behind it, thanks to an undisclosed settlement. The news comes at a perfect time for the automaker, which is still setting up its dealers there.
According to an email from Tesla cited by Bloomberg, the two sides came to an agreement "completely and amicably," but the business isn't revealing what it cost to resolve the conflict. As part of the settlement, Zhan is also transferring his ownership of the tesla.cn and teslamotors.cn over to the company. "Mr. Zhan has agreed to have the Chinese authorities complete the process of canceling the Tesla trademarks that he had registered or applied for, at no cost to Tesla," said the statement, according to Bloomberg. "Collectively, these actions remove any doubt with respect to Tesla's undisputed rights to its trademarks in China."
Zhan had claimed to hold the trademark on the Tesla name in China since 2009, but he was appealing a ruling by the country's courts invalidating those rights. The situation heated up even further in July when Zhan sued the automaker for trademark infringement and asked for 23.9 million yuan ($3.9 million) in damages, plus for the company shut down all of its operations there. Tesla had reportedly already attempted to settle with him years ago for 2 million yuan ($325,000 at current rates), but Zhan countered with a figure of the equivalent of over $32 million.

Weekly Recap: The divergent paths of Tesla and Fisker

Sat, 02 Aug 2014



There's no doubt that Tesla is downshifting while Fisker has been grinding its gears. But it wasn't always that way.
In the wake of Tesla's recent success, it's easy to forget that there were once two California electric carmakers with bright futures.

Edmunds' long-term Tesla Model S has been wonderful, woeful

Thu, 31 Jul 2014

We generally don't report on other outlets' long-term model tests, but Edmunds just completed a 17-month ownership experience with a 2013 Tesla Model S. It's just too interesting not to share.
The site bought a 2013 Model S Performance model for the added range of its 85-kilowatt-hour battery and tossed on a good variety of options for a total price of $105,005, including a wall charger. In terms of driving the electric hatchback, the folks there seemed to love it. There were a few minor gripes, but for the most part it offered sufficient driving range, plenty of space and generally good quality.
However, the ownership experience was hardly flawless. The journalists there were never quite able to hit the Model S' promised range of 265 miles, with a best real-world result of 230.4 miles during their ownership. Also, while they had it, the Model S had a rash of unscheduled trips for service - seven times - and their Tesla left them stranded by the side of the road once.

Autoblog editors come clean about their controversial automotive beliefs

Thu, 31 Jul 2014

We'd also like to invite you to share your unpopular and controversial opinions with us and the Autoblog faithful down in Comments. Don't be ashamed - this is a safe place.

Elon Musk to get spot on The Simpsons

Wed, 30 Jul 2014

It's hard to believe that The Simpsons is moving into its 26th season, but there's good news for auto enthusiasts, especially of the EV variety. The show's executive producer, Al Jean, confirmed on Twitter that Tesla Motors CEO Elon Musk would have a guest spot on the show in the upcoming season. Even better, it sounds like a pretty significant role.

Icon Helios streamliner with Tesla bones is a dream from which we don't want to wake

Wed, 30 Jul 2014

When it comes to truly, genuinely interesting automotive design and craftsmanship, Icon is one of the finest outfits in the game. We've covered the company and its founder, Jonathan Ward, in the past, and have remarked on just how fully and intricately done the automotive art it turns out is. The company's next big thing, though, is a far cry from the modified Land Rovers and Chevy Thriftmaster pickups.
The sketches you see above are of the Helios, Icon's latest mad creation. While still remarkably early in the planning phases, it's safe to say that the streamlined, Art Deco-inspired, boat-tailed (every vehicle should be boat-tailed) coupe is the company's single most ambitious vehicle yet.
"Although almost all of our projects thus far have been recreations inspired by vintage vehicles, I am fascinated about the concept of revisiting history in our own way," Ward told Jalopnik staffer and former Autoblog editor Damon Lavrinc. "The most interesting way to do this is by celebrating a particular era of design, or design language."

Recharge Wrap-up: Panasonic, Tesla on Gigafactory deal?

Tue, Jul 29 2014

Bentley has been awarded the Carbon Trust Standard for reductions of carbon, water use and waste production in manufacturing. The Carbon Trust is an organization that helps groups such as businesses and governments reduce carbon emissions, use of energy and resources, and waste output. From 2011 to 2013, Bentley reduced CO2 emissions by 16 percent per car manufactured, curtailed water use by 35.7 percent, and saw significant waste reductions. Darran Messem of Carbon trust says, "Bentley is clearly passionate about continuing to improve its environmental performance, which is reflected by the fact the company has consistently invested in new technology." Read more in the press release below. Chevrolet is giving 12 Volts to MBAs Across America. The organization will use the range-extended electric cars in its efforts to help MBA students learn from and work with small business owners. As part of the MBAs Across America program's first year, four students drove 8,000 miles to provide entrepreneurs with free business counseling. The program has expanded, and this year, teams of MBAs will use the Volts to travel to 25 cities to offer their services. Learn more about the partnership between Chevrolet and MBAs Across America in the press release below. A professor from the University of Michigan has found fuel cycle analysis to be too flawed to be relied upon for measuring CO2 impacts of transportation fuels. Professor John DeCicco of the university's Energy Institute feels that the flaws in calculating the carbon footprint of liquid fuel production and combustion make such lifecycle analysis impractical. He suggests, instead, to focus to carbon capture. Since capturing CO2 directly from a vehicle is probably never going to happen, DiCicco believes the solution is to capture carbon from the atmosphere in sectors outside of transportation. Says DiCicco, "Research should be ramped up on options for increasing the rate at which CO2 is removed from the atmosphere and on programs to manage and utilize carbon fixed in the biosphere, which offers the best CO2 removal mechanism now at hand. Such strategies can complement measures that control the demand for liquid fuels by reducing travel activity, improving vehicle efficiency and shifting to non-carbon fuels."
