Car Hacking 101: Here's what motorists should know [w/video]

Cars are nothing more than computers on wheels. As such, they're vulnerable to hackers. Most people who work within the auto industry have understood this for years, but for the broader American public not paying as close attention, three storylines emerged recently that underscored this new vehicular reality. First, German researchers found a flaw in BMWs remote-services system that allowed them to access the telematics units in vehicles. Then, a 60 Minutes report demonstrated that researchers could remotely infiltrate a Chevy Impala and override critical functions, like acceleration and braking. Finally, a US Senator released a critical report (see video above) that found almost all automakers are unprepared to handle real-time hacks of their vehicles. Those reports come on the heels of two previous instances in recent months when researchers demonstrated the capability to hack cars. All this news can be disconcerting. If you're late to the concept of car-hacking and wondering how this is possible, we've got you covered. Here's your quick primer on what you need to know. 1. How Did My Car Become A Computer? On the outside, cars haven't changed all that much over the past couple of decades years. On the inside, however, the amount of electronics and software has dramatically increased. Most new cars contain more than 50 microprocessors known as electronic control units. These ECUs control everything from airbag deployment and navigation systems to throttle control and braking, and they're usually connected to each other on an internal network called the CAN bus. 2. What Exactly Is Car Hacking? Depends who you ask. Automakers might consider anything that alters the car from its state of manufacture as a 'hack.' For example, if you're chipping the engine – re-calibrating those ECUs to increase your horsepower – some people might consider that a hack. But in the context of the recent news reports, security experts are focused on unwanted, unauthorized cyber intrusions into a vehicle. Once inside your car, prospective attacks could range from minor things like eavesdropping on conversations via an infotainment system and unlocking car doors to major concerns, like overriding driver inputs and controlling braking, steering and acceleration. 3. How Is This All Possible? Any part of the car that communicates with the outside world, either via a remote or direct connection, is a potential entry point for hackers.

2015 BMW X4

BMW has been in the line-blurring business of late, with the original X5 "Sports Activity Vehicle" muddling the line between SUVs and sport sedans in 1999, the 5 Series Gran Turismo challenging what our definition of "Gran Turismo" means in 2009, and pretty, low-roofed four-doors like the 6 Series Gran Coupe and the fresh new 4 Series Gran Coupe broadening the meaning of the word "coupe."
In the midst of all of this, BMW blurred the lines around both the SUV and coupe genres with its big, heavy, and in many ways ridiculous X5-based "Sports Activity Coupe" (cue collective eye-roll), dubbed X6. Auto wags scoffed at its lack of utility, compromised outward visibility and added cost, but a more emotional public was apparently smitten enough by its aggressive looks to avail itself of some 250,000 of them worldwide in six model years on sale.
Enter the all-new 2015 X4 crossover - err, "Sports Activity Coupe" - which BMW hopes will perform as well in the compact category as the X6 has on the next rung up the ladder. Like the X6, the X4 is a tough sell on paper: it's more expensive and less practical than the X3 on which it's based; it's heavier, despite the loss of interior space; and it doesn't even hold as much stuff in the back as the 3 Series wagon. As with the X6, the X4 is essentially a high-riding style statement that, like proper coupes (the two-door kind), says to the world, "You fools can take your need for practicality and shove it. I just want to look good."

Tesla, BMW and Nissan meeting in secret to discuss charging tech

It's interesting what's happening in the electric vehicle field. It used to be that BMW and Tesla were competitors. Then – and of course they're still competing, especially in the public mind – they were working together on ... something. Maybe. And now, the Financial Times reports that the two luxury automakers are meeting with Nissan. Again, maybe. The scuttlebutt is that the three companies are interested in working together on something to do with charging electric vehicles, potentially a global recharging standard. Currently, when it comes to fast charging, BMW uses the SAE Combo standard, Nissan uses CHAdeMO and Tesla uses its own Superchargers. The meeting was prompted by Tesla opening of all of its patents the other day, FT says. Speaking during the recent annual shareholder meeting, Musk said he was "more than happy to have other manufacturers" use Tesla's Superchargers but that, "there is no other electric car that can accept anything close to 135 kilowatts." Let's assume the technical hurdle can be overcome. With any potential patent/licensing problems out of the way, these discussions with BMW and Nissan might be revolving around this other angle that Musk mentioned: "They (other automakers) just have to contribute to the capital cost, so figure out what percentage of the time are their cars using the Supercharger network and then they can make a contribution proportionate to their customer usage of the Supercharger network." That certainly sounds like something that could take some time to figure out.
