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.

BMW unveils 2016 X5 M and X6 M super CUVs

The second-generation BMW X5 M and X6 M have officially made their arrival for the speed-obsessed, crossover-loving masses that aren't willing to turn to Mercedes-AMG or Land Rover Special Operations.
While the new models retain their 4.4-liter, twin-turbocharged V8s, power has increased from 555 horsepower to 567 ponies. Torque is up more significantly, climbing from 500 pound-feet to 553 pound-feet. The extra twist is slightly less accessible, with peak grunt arriving between 2,200 and 5,000 rpm, rather than the earlier model's 1,500 to 5,650. Still, we'll take the ten percent increase in torque as a net win.
The big powertrain switch sees the old X5/6 M's six-speed automatic replaced with an eight-speed Steptronic transmission from BMW M. This new gearbox feeds power to an xDrive all-wheel-drive system that can variably shuffle up to 100 percent of power to either axle. In conjunction with the force-induced thumper under the hood, this powertrain arrangement allows both M models to hit 60 miles per hour in just four seconds. That's a mightily impressive stat in a 5,000-plus-pound vehicle.

BMW X5 driver repeatedly fails to understand big rig braking distances

Nobody should be shocked that a big, heavy vehicle like a semi truck takes a longer distance to stop than the average passenger car; it's just basic physics. However, this BMW X5 driver seemingly has a major problem grasping the concept, and it results in some serious damage to the back of his SUV.
The whole incident is very confusing to watch. The BMW doesn't even seem to have a reason to slow down before the semi slams into the back of it at fairly high speed. But to make the situation even weirder, the crashes just keep happening again and again.
To give the BMW driver a little credit, he appears amazingly calm when surveying the damage afterward. But you have to wonder what this guy was thinking when trying a harebrained move like this. Check out the video to watch the carnage unfold.
