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.

2014 BMW 4 Series Convertible is easy, breezy, beautiful

BMW debuted its 2014 4 Series Convertible today at the LA Auto Show, and the sporting two-door will feature a folding hardtop - like the convertible 3 Series before it - and be offered in 428i and 435i guises.
The 428i Convertible is equipped with BMW's 2.0-liter turbocharged inline four-cylinder engine, which pumps out 240 horsepower and 255 pound-feet of torque - good for sprinting from 0-60 miles per hour in 6.2 seconds. The 435i Convertible gets the 3.0-liter turbocharged inline six-cylinder engine, which steps up output to 300 hp and 300 lb-ft of torque. The topless 435i drops the 0-60-mph time to 5.5 seconds. Both cars come standard with an eight-speed automatic transmission, and BMW says that a manual transmission will not be offered on 4 Series Convertibles in the US market.
The 4 Series Convertible will be offered in Sport Line, Luxury Line and M Sport trims. Pricing starts at $48,750 for the 428i Convertible and $54,900 for the 435i. Head on below to peruse the (long) press release for details.

AWD BMW M5 is headed our way

Remember the rumor about the BMW M5 going all-wheel drive? Well, there's definitely some truth there because these spy shots show BMW testing the Autobahn-storming sedan with the ability to spin the front and rear wheels. Our spy shooters grew suspicious when they saw this seemingly normal-looking M5 appearing to turn all four wheels during ice testing. They checked it out and snapped these shots underneath clearly showing power routed to the front axle. While this shows that the tech is at least being tested on a current-gen M5, all-wheel drive is probably not coming until the next 5 Series model, which is already being evaluated. The idea of power going to the front and rear axles for this sport sedan might polarize some hardcore brand fans as a break with tradition. However, the head of the M division thinks the change is a priority to actually put torque down effectively. The future vehicle is slated to get at least 600 horsepower and pack it into a lighter platform. Rear-drive M5 purists can take heart, though. The all-wheel-drive system would reportedly be an option, and it would be rear-biased to still let drivers hang the tail out, if the desire arises.
