Tesla's 'D' Adds All-Wheel Drive, Safety Features

Tesla Motors CEO Elon Musk unveiled a new version of the luxury electric car maker's Model S sedan that includes all-wheel drive and self-driving "auto pilot" features. The open-to-the-public event Thursday night included free alcohol and test rides on an airport tarmac. With more than 1,000 Tesla fans in the audience, Musk explained that the current Model S is a rear-wheel-drive car with one motor, but a new version will have two motors - one powering the front wheels and one powering the rear wheels. All-wheel drive helps grip slippery roads and is standard on many luxury sedans. Analysts have said Tesla needed it to boost sales in the Northeast and Midwest, as well as Europe. The company sold 13,850 cars in the U.S. this year through September, down 3 percent from a year ago, according to Autodata Corp. Unlike all-wheel-drive systems on gas-powered cars, Tesla's system improves speed, acceleration and mileage by optimizing which motor is used, Musk said. The dual motor version of the P85 performance sedan will have a top speed of 155 mph, compared with the current 130 mph. It will accelerate from 0 to 60 mph in 3.2 seconds, akin to exotic sports cars. "This car is nuts. It's like taking off from a carrier deck," Musk said at the municipal airport near Los Angeles where another of Musk's companies - the commercial rocket firm SpaceX - is based. The crowd obliged with cheers and applause. Tesla is also significantly upgrading its safety features through a combination of radar, image-recognition cameras and sonar. The Model S will right itself if it wanders from its lane and brake automatically if it is about to hit something. Those features are offered on luxury competitors, as well as mainstream brands such as Ford, Hyundai and Toyota. But Tesla is going a step further. Its new system will move the car over a lane when the driver uses the turn signal. It will also use cameras to read speed limit signs and decelerate accordingly. Volvo has a system that reads signs and alerts drivers if they are over the limit but does not change the speed. Musk said "auto pilot" does not mean the car could drive itself - as he put it, a driver cannot "safely fall asleep." Pulling together all the driver-assist features impressed Brian A. Johnson, an analyst with Barclay's. "It's a year ahead of the timeframe I was expecting," he said.

Tesla Model S driver goes from Mexico to Alaska, loves the experience

As range anxiety lessens, and more chargers are installed along major roadways, increasing numbers of people are taking road trips in their electric vehicles. The Tesla Model S in particular has become the go-to vehicle for electric touring. When equipped with the 85-kWh battery pack, the Model S offers up to 265 miles of range, which is a respectable distance to cover in one sitting. It's still notable, though, when a Model S driver makes a particularly long trek, especially when much of the route is mostly devoid of Tesla Superchargers. Guy Hall, the president of the Sacramento Electric Vehicle Association, drove his Tesla Model S from the US/Mexico border outside of Yuma, Arizona to Fairbanks, Alaska in 17 days. He calls the trip the T5 (Tesla Tijuana to Tundra Tour), and he encourages other people to make the journey, despite the challenge of driving through areas that are sparsely populated. Charging "slows you down to take a break. I've met some marvelously nice people here." – Guy Hall Driving through California, Oregon, and Washington isn't too difficult. North of Vancouver, British Columbia is where charging starts to get a little tricky. Hall says that when gas stations with electrical outlets were few and far between, he stopped at RV parks to charge (a trick of the Tesla tripping trade we've seen before). Hall made use of his charms, and would offer rides in his Model S to curious employees at mechanic and welding shops in return for the opportunity to more quickly charge his battery using their 240-volt outlets. While the trip took quite a bit longer than it would have in one of the Ford Tauruses Hall owned before switching to EVs, it allowed him to soak in the beauty of his surroundings, meet people along the way and answer questions about the Model S. Charging "slows you down to take a break," says Hall. "I've met some marvelously nice people here." Guy Hall now hopes to turn the T5 trip into a sort of event, where EV drivers who make the trip in the shortest amount of time could win a trophy. If you're interested in making a similar journey, Hall has posted his route from Sacramento northward, here. Read more about Hall's journey at News Miner, or read his thread at Tesla Motors Club.

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."
