Tesla says Germany concludes Model S fire probe without further action

It was the perfect storm: three Model S fires in six weeks were enough for the National Highway Traffic Safety Administration (NHTSA) to start an investigation into the two US fires in mid-November, but as it turns out, the German government was paying attention too. According to Tesla, Germany's Kraftfahrt-Bundesamt (KBA), or Federal Motor Transport Authority, already has completed an investigation into the two US fires and the one in Mexico, found no manufacturer-related defects and will not take further measures.
According to a statement issued by Tesla, the automaker says it was contacted by the KBA about the post-crash fires, and it "provided the KBA with data and additional information regarding each of these incidents." The KBA subsequently sent a letter in German to Tesla saying the investigation was complete and that no manufacturer-related defects could be found. (Take a look at the letter here.)

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

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.

Tesla Model S vulnerable to hackers?

Next time you walk by a parked Tesla and its sunroof is opening and closing with nobody sitting inside or around it, you could be witnessing a hacker moment. For all of its strengths as a car, the Model S reportedly has a weak spot: the security of its API (application programming interface) authentication, according to an article in the O'Reilly Community by George Reese, executive director of cloud management at Dell. Tesla develops and uses its own API authentication protocols, which have made access to certain Model S functions too easy for hackers, Reese says - himself a Model S owner.
At question is the Tesla REST API, which is accessed via a web-based portal, usually by Model S owners with their iPhone or Android-based smartphone, to perform a variety of menial tasks and check the status of the car. The Tesla-registered e-mail and password of the car owner is used to access the API through a web portal, which creates a "token" that lasts for three months. During that period, owners access the Tesla REST API via the token without the use of their log-in information. Unfortunately, the tokens and their respective cars are stored on website databases that are all too easy to hack, Reese explains, and if a hacker gains access, "it has free access to all of that site's cars for up to three months with no ability for the owners to do anything about it." On top of that, there is no way to revoke access of a compromised application.
Reese says that "there's nothing in the API that (can? should?) result in an accident if someone malicious were to gain access." The API can check the car's battery charge, operate climate control, operate the sunroof, identify car location, honk the horn, open the charge port, and perform other similar operations. But, he cautions, "Perhaps the scariest bit is that the API could be used to track your every move."
