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 unleases new M4 as MotoGP safety car

BMW has some considerable racing prowess to crow about, and draws on those credentials to create models like the new M4. But it's not about to rest on the laurels it's won at the end of innumerable races past and present. Mere months after the release of its latest performance coupe, BMW has already revealed a new M4 touring car for the DTM series, and has now unveiled its new M4 safety car for the MotoGP motorcycle championship.
Revealed on the BMW M Facebook page and set to debut at the front of the grid at the season opener in Qatar a couple weeks from now, the new M4 safety car is just the latest in a long string of official vehicles it has provided to the MotoGP series. Previous examples have included everything from the 1M Coupe to the M6 and the X6 M.
Like its predecessors, the M4 safety car features emergency lighting, special equipment and of course BMW's trademark white livery with red, navy and light blue stripes that, in this arrangement, give the new Williams Martini Racing livery a run for its money. Logos promote the BMW M Performance Parts you can buy to bring your own Bimmer up to spec, which on this car isn't likely have changed much from stock.

2015 BMW M3 Sedan, M4 Coupe are officially revealed [w/video]

The new 3.0-liter inline-six makes 425 turbocharged horsepower from 5500 rpm all the way up to 7300 rpm.
BMW has announced the 2015 M3 Sedan and M4 Coupe, high-performance versions of the new 3 Series and 4 Series that launched this year. The new Ms have stirred controversy in a variety of ways, but one must remember that the M cars traditionally don't follow a specific mold.
