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 i3 range-extender lawsuit supports Tesla's store argument

Tesla's argument that it needs to own its stores in order to sell its electric vehicles and give customers better information is about to get bolstered by an unlikely source: BMW. The German automaker is the subject of a class-action lawsuit stemming from the performance of the range-extended version of its i3 plug-in. And at least one green-car advocate and i3 owner says the problem could have been avoided by better education at BMW dealerships. The lawsuit was filed in California by some owners of the BMW i3 REx, i.e. the version that's equipped with a gas-powered "range extender," according to Green Car Reports. The issue is that, when the car's battery starts running low and the powertrain is subjected to extended stress, such as a long uphill highway stretch or a fully loaded vehicle, the car can slow from highway speeds to as slow as 45 miles per hour without warning. The claim states that the vehicle can post a danger as a result, while BMW has declined comment, citing pending litigation. Meanwhile, Tom Moloughney, owner of the first BMW i3 REx to be sold in the US, says the problem might rest at the dealership level. Moloughney says that if dealers explained the car's mechanics better – especially the fact that the range extender is essentially a 34-horsepower, two-cylinder motorcycle engine whose power is limited – drivers would be better informed about what could happen when the battery power is sapped at highway speeds. While Tesla EVs don't have the same sort of REx powertrain, this argument nicely dovetails with what Tesla Motors has been saying for a long time, that its cars should only be sold at company-owned stores because third-party dealers are less likely to understand and explain the nuances of electric vehicles. No word on whether Elon Musk's lobbyists are getting together with lawyers representing the Ultimate Driving Machine.

BMW offering glitch fix for i3 with range extender

The BMW i3 has received quite a bit of acclaim since its release, with the electric powertrain grabbing a spot on Ward's 10 Best Engines list and the high-tech machine earning the nod as 2015 Green Car of the Year. However, Consumer Reports uncovered a vexing problem with the range-extended version of the hatchback that has plagued it until a recent software update. While CR was driving the range-extended i3 last year, it discovered that when the internal combustion engine was running during low states of charge, hard acceleration could suddenly cut back with no warning to the driver. This was especially problematic when passing. BMW knew about the issue and promised a software update in the spring. That improvement is now available. BMW spokesperson David Buchko tells Autoblog that the software update adds a percent-of-charge indicator to all models of the i3 to let drivers know just how much juice is left. For the range-extended model, it also provides a warning of possible power reduction when the charge reaches two percent. According to Consumer Reports, the revision lets the car anticipate needing more reserve power based on the topography from the navigation system, as well. For any i3 drivers who want the upgrade, they need to visit a dealer for installation, according to Buchko, but it should be come at no cost to owners. Related Video:
