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 rethinks all-wheel-drive M cars

BMW M hasn't been able to decide whether it wants to jump on the all-wheel-drive bandwagon or not (with the exceptions of the X5 M and the X6 M, which are based on AWD architecture). That might be changing though, since M's president Friedrich Nitschke recently realized that 70 to 80 percent of Mercedes-Benz E63 AMGs are ordered with all-wheel drive. Earlier this year, Nitschke said that there were no new AWD M models planned, so this comes as somewhat of a surprise.
"On our cars we are thinking of all-wheel drive, but it won't come before we get the successor of the M5 and M6," Nitschke said in a Motoring report. "That's the timing and it's not practical to react in the current life cycles."

BMW i3 with range extender won't get all the EV tax benefits in NJ

Everyone loves that new-car smell, but not everyone loves that new-car tax. And whoever in New Jersey thought the extended-range version of the BMW i3 plug-in would be exempt from said tax was sorely mistaken, Green Car Reports says. To paraphrase the Garden State's favorite son, Bruce Springsteen, the first kick those drivers will take is when they hit the ground. BMW said last year that the BMW REx would qualify for new-car tax exemptions in New Jersey and in Washington State. The car's all-electric range was recently estimated at 72 miles and it has another 87 miles of gas-powered range-extended capability. Unfortunately, the range extender not only tacks on $3,850 to the car's sticker price but adds on almost that much again because New Jersey's seven-percent sales tax applies to all cars with any sort of gas-powered engine. BMW didn't respond to a request for comment about the New Jersey situation from AutoblogGreen. In other New Jersey electric vehicle news, the Consumer Affairs Committee of the New Jersey State Assembly will discuss the legality of Tesla selling directly to consumbers tomorrow. The extended-range i3 is involved in a different issue on the other side of the country. BMW said earlier this year that the REx would qualify for California's white zero-emission vehicle stickers that allow for solo access to high-occupancy vehicle (HOV) lanes. These unlimited white stickers can go on any EV, but the REx version only qualifies for the green stickers, which are designated for plug-in hybrids and extended-range plug-ins and the state has run out of those.
