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."

BMW looking to fix i3 acceleration problem uncovered by Consumer Reports

The BMW i3 has been hailed in some quarters as the future of electric mobility, what with its innovative carbon-fiber-reinforced plastic body and commitment to sustainable materials wherever possible. The modernist little hatch is even available with a 650cc two-cylinder gas engine with 34 horsepower to act as a range-extender for those who want it. However, that optional engine might have a drawback - at least for the moment.
Consumer Reports brought the problem to light when one of its drivers was behind the wheel of an i3 using the range-extender. When the driver attempted to pass another vehicle on a rolling, two-lane road, the BMW suddenly had no power to accelerate - a scary situation. CR started examining the car and found something pretty shocking: After driving at a constant speed for a while without any regenerative braking in range-extended mode, acceleration to 60 miles per hour plummeted from about 9 seconds normally to a staggering 27 to 40 seconds in their testing.
A BMW spokesperson told CR that it knows about the problem and has a fix coming next spring that also works on current models. The upgrade includes a state of charge indicator, a warning about loss of power and uses the car's navigation to boost the battery before driving on rolling terrain. It is not clear if the severe power deficiency will also eventually result in a recall.
