Tesla wants to hackproof the Model S

Apparently, Tesla Motors is abiding by the wise words of Chinese military general Sun Tzu to keep its friends close and its enemies closer. The tech-heavy electric vehicle maker attended the recent Def Con conference in Las Vegas, The Wall Street Journal reports, in order to learn about computer-security advances and to attract hackers. Come and get it. But Tesla's there for good reason. The California-based automaker is looking to hire at least 30 hackers from the conference (which is chock full of hacking competitions), according to the Journal. Kristin Paget, Tesla's self-described "hacker princess," notes that with the automotive industry increasingly relying on networked communications for features ranging from on-board entertainment to parallel-parking controls, automakers are very vulnerable to whims of expert hackers. Tesla has a built-in way to play defense since it already regularly sends out wireless software updates for its Model S sedan. In February, Tesla hired Paget away from Apple Computer to improve its virtual shields. Paget previously worked at Microsoft, specifically with its Vista operating system, before joining Apple in 2012. She once gained notoriety for writing a manual on how to build a fake cell tower that was capable of intercepting mobile-phone calls, so she's got a good eye for these things.

GM CEO Akerson calls out Tesla, says Cadillac will compete on EVs

Cadillac will be taking on Tesla Motors, the underdog EV manufacturer that's seen heaps of critical acclaim and stock market buzz with its most recent sedan, the Model S. "If you want to compete head-to-head with Tesla, and we ultimately will, you want to do it with a Cadillac," Dan Akerson, the chairman and CEO of General Motors, told media in Washington, according to The Detroit News.
Akerson continued, telling The News, "We'll sell more Volts and lose less money on the Volts than they'll lose on the Model S." He also took time to point out that Tesla getting vehicles out to customers isn't a guarantee of success or permanence, using Fisker as an example, saying "Does anybody even remember Fisker? I mean, there were a number of them; they are all gone."
This strong talk from Akerson comes after Doug Parks, another GM exec, let slip that the Detroit-based manufacturer has an EV in the works that will cover 200 miles per charge and only cost about $30,000, a massive upgrade over similarly priced EVs that struggle to top 100 miles per charge. Until that vehicle arrives, though, GM is preparing the Cadillac ELR, a small coupe that, like the Volt with which it shares technology, uses a gas engine as a mobile generator to recharge the batteries. Akerson took aim at Tesla again, saying, "But I do think when the ELR comes out late this year, early next - it's certainly the same postal code as Tesla, but now we're going to move up. It's not going to be a mass-produced car."

What does the open patents deal mean for Tesla ... and BMW?

Gift to the world or trade bait? Tesla Motors announced this week it would open its patents for other automakers to use. That has analysts guessing whether the California-based electric-vehicle maker is looking to either swap trade secrets with other automakers or to expand the proverbial pie that represents the plug-in vehicle market. For its part, Tesla says the answer is B. BMW, which is establishing its i sub-brand of plug-in vehicles, would be a natural collaborator with Tesla, Forbes says. In fact, executives from the two companies met in Europe this week. Details were not released, but a BMW spokesman said, "Both companies are strongly committed to the success of electromobility and discussed how to further strengthen the development of electromobility on an international level." While Tesla brings battery technology to the table, BMW offers its carbon-fiber advancements that lighten vehicle-body weight. Those advancements are key to range-extending efforts and could do wonders for Tesla on its journey to help spur technology for the sake of getting more of the general public to accept plug-in technology as a viable first-car option. Then again, Forbes says Tesla, whose investors include Mercedes-Benz parent Daimler and Toyota, may be keeping its best technologies to itself by not patenting certain advancements at all. What's in Tesla's patent pool? uAutoInsurance analyzed Tesla's 249 patents and found that 104 of them related to battery technology, while 28 pertained to recharging activity, which wasn't surprising (about a quarter of those 249 patents couldn't readily be categorized). Tesla also has nine patents related to sunroof technology. The company is based in California, after all.
