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.

18,000 BMW models recalled for potential fuel pump failure

BMW will be recalling over 18,000 vehicles from the 2, 3 and 4 Series families, including vehicles from model years 2014 and 2015, due to potentially bad fuel pumps. The full roster of vehicles includes four- and six-cylinder models of all hardtop 2 Series models, rear-, all-wheel-drive and Gran Turismo versions of the 3 Series, and coupe, convertible, Gran Coupe, rear- and all-wheel-drive 4 Series models. The 3 Series ActiveHybrid is also included in the recall, although the 3 Series diesel line has been left alone. According to the bulletin from the National Highway Traffic Safety Administration, "improper" nickel plating on some of the parts could lead to a failure of the fuel pump, leading to a stall situation. BMW is planning to notify owners and will begin replacing the fuel pumps of affected vehicles at the end of the month. Scroll down for the official NHTSA bulletin, which includes a complete breakdown of individual models affected by the recall. Related Video: Report Receipt Date: MAR 31, 2015 NHTSA Campaign Number: 15V189000 Component(s): FUEL SYSTEM, GASOLINE Potential Number of Units Affected: 18,054 Manufacturer: BMW of North America, LLC SUMMARY: BMW of North America LLC (BMW) is recalling certain model year 2014 228i Coupe, M235i Coupe, 320i, 320xi, 328i, 328xi, 335i, 335xi, ActiveHybrid 3, 328xi Sports Wagon, 428i Coupe, 428xi Coupe, 435i Coupe, 435xi Coupe, 428i Convertible, 428xi Convertible, 435i Convertible, 328xi Gran Turismo, 335xi Gran Turismo, and 2015 428i Gran Coupe, 428xi Gran Coupe, and 435i Gran Coupe vehicles. Improper nickel plating of components within the fuel pump may result in the fuel pump failing. CONSEQUENCE: If the fuel pump fails, the vehicle may stall without warning, increasing the risk of a crash. REMEDY: BMW will notify owners, and dealers will replace the fuel pump, free of charge. The recall is expected to begin April 30, 2015. Owners may contact BMW customer service at 1-800-525-7417. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

BMW X6 M said to lap the 'Ring in 8:20

Bimmer Today reports that the German rag Auto Zeitung ran an Audi RS3 and a BMW X6 M around the Nurburgring together, and the hotted-up sports activity vehicle came in just five seconds behind the white-hot hatch. Driven by 'Ring regular Horst von Saurma, the RS3 ran its lap in 8 minutes, 15 seconds, and the X6 M ran an 8:20. If those times are accurate, that makes the X6 M the second fastest production SUV on the lap-time list according to Wikipedia: ahead of it is the 550-hp Range Rover Sport SVR, which ran a time of 8:14. That time puts BMW's 575-horsepower, 5,200-pound SUV four seconds ahead of the time registered by the last-gen, 555-hp X6 M, and well ahead of the Porsche Cayenne Turbo S that Sport Auto clocked an 8:34 with. It would not, however, match the predictions that X6 M project manager Herbert Bayerl made for it in an interview with Sport Auto earlier this year. Bayerl said "The new BMW X6 M moves at the level of M3," speaking of the E92 BMW M3 that Sport Auto ran around the 'Ring in 8:05. It is, though, two seconds faster than the E46 M3, which lapped in 8:22. Bayerl called out the Range Rover Sport SVR directly, saying, "We have been traveling much faster in testing and have undercut the time of Range Rover several times," and "We don't need any special attachments to go faster." Auto Zeitung's report on the lap is only for subscribers so we'll have to wait for more official news. For the apples-to-apples comparison we'll be looking forward to Sport Auto's hot lap, then we'll know if the Range Rover has anything to fear. Related Video:
