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 X7 rumored to get BMW's best interior, 130,000-euro price

Spanish outlet Motor.es has some info on the coming BMW X7, the sport activity vehicle that will take the Munich brand to the penultimate SUV segment. Unnamed sources said BMW has been working on both the X7 and the future Rolls-Royce all-terrain vehicle for almost two years, and that in BMW guise it will ride on the CLAR (CLuster ARchitecture) platform that will make an appearance later this year under the new 7 Series. The Rolls-Royce, on the other hand, will get its own aluminum spaceframe. The two vehicles will share components, though, which are now being tested. Running gear and engines will borrow from the X5 and X6 tool chests, with rear- and all-wheel-drive configurations mooted and engines ranging from the TwinPower 3.0-liter six-cylinder to an uprated version of the 6.0-liter V12 in the 760iL. The 4.4-liter V8 is mentioned as the middle child and perhaps the base for an X7 M, should one be made. A plug-in hybrid offering could swipe the unit from the X5 xDrive40e PHEV, good for 55MPGe in that current application. The interior, we're told, will be the nicest seen on any BMW, said to surpass that of the new 7 Series. We'll have to wait two years to find out how close all of that is to the mark, but the tidbit that might need some salt sprinkled on it right now is the predicted price: Motor.es says 130,000 euros in Europe, to start. That's not the first time a sky-high price has been predicted, but a leap that far beyond the six-figure mark would readjust all of our expectations for the vehicle when an X5 cost 53,700 euros in France and an X6 costs 70,900 euros. Other outlets predict US pricing to start from around $60,000; the X5 costs $53,900 here, the X6 is $59,600.

BMW expands Takata airbag recall nationwide, 140k 3 Series affected

Following the urging of the National Highway Traffic Safety Administration, BMW has expanded its recall of vehicles equipped with Takata airbag inflators to cover the entirety of the United States, rather than just high-humidity areas. That means there are about 140,000 owners of 2004 to 2006 model year BMW 3 Series coupes, convertibles, sedans and wagons (that means owners of both E46 and E90 3ers should take note). It's unclear if this recall includes the high-performance M3 Coupe and Convertible. With the expansion of its airbag recall, BMW joins Honda, Mazda, Ford and Fiat Chrysler in moving from a regional to a nationwide recall of vehicles equipped with Takata airbags. According to Reuters, BMW claims none of its vehicles have been subject to the potentially harmful airbag deployments.
