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.

Guess what BMW's '30 Years M3' special edition celebrates

It's anniversaries on top of anniversaries at BMW in 2016. The company celebrated its 100th year of existence at an elaborate celebration in March, last week we got a new hommage concept to mark five decades since the iconic 2002 debuted, and now, in time for the holiday weekend, there's this limited-edition M3. Wait, that's not what this holiday is for? This celebratory sports sedan gets the not-quite-grammatical name of "30 Years M3," which is totally grammatical when translated back into German ("30 Jahre M3"), and BMW plans to build just 500 of them for the whole world. We don't yet know how many will come to the US, but seeing as ours is one of BMW's larger markets, we are at least banking on "some." What makes it neat besides rarity? It comes with pretty much everything you can get on a standard M3, including the Competition package with its 444-horsepower engine tune, Adaptive M suspension, and Active M differential. To that it adds an M exhaust with black tips, the requisite dash plaque, shouty door sills, and unique "30 Years M3" badges on the fender gills. The interior has special seats with gray or blue inserts and stitched headrests, plus seat belts with M three-stripe trim. (And yes, the cars in the photos say "30 Jahre M3," but we already explained that, right?) And then there's the paint. It will be available in Macao Blue metallic, a color that was available for special order on the E30 M3. And if there's any car that deserves some celebration, it's the original M3. Happy 30th, neat car. Related Video:

As US exports top 2 million, is America becoming the world's source of cheap cars?

North American auto production is booming with 2014 figures just shy of the of the 17.3-million vehicle record set in 2000. With more models being built on the continent, even more are being shipped overseas. Factories in the US exported 2.1 million cars last year – the highest number ever. About half of those went to Canada and Mexico, but more than ever have been heading to places like the Middle East and China. The upswing comes in part from from after-effects from the Great Recession, according to The Wall Street Journal. With a weak dollar and lower production costs after the financial crisis, building vehicles in the US was relatively cheaper and more competitive in the world. At the same time buyers around the world are going crazy for crossovers. According to the WSJ, BMW and Mercedes-Benz are already exporting the majority of their US production of these models overseas. Both automakers have also announced investments to expand production further here to send more vehicles abroad. Even Honda has been shipping more models out of the country than it imported here. There is a concern this international strength could start slowing because the dollar is strengthening against other currencies, though it's too early to know what the actual effect of this could be, according to the WSJ. "Of course, we closely watch currency exchange, but we don't make changes in production or allocation based on temporary fluctuations in the exchange rate," Ford North American boss Joe Hinrichs told the newspaper.
