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 celebrates with M4 DTM Champion Edition

Go back just a few seasons, and Germany's DTM touring car series was a straight-up competition between Audi and Mercedes-Benz. But BMW rejoined the race in 2012, winning both the drivers' and constructors' titles on its first year back and celebrating with a special matte-black M3 DTM Champion Edition. Last season, it won the constructors' championship but not the drivers', and this year it did the opposite. In short, it's been an impressive comeback for the Bavarian automaker, and to celebrate this year's accomplishments, it's followed up with the new M4 DTM Champion Edition for Europe you see here.
Based on the new M4 coupe - which forms the basis for BMW's DTM challenger as well as its pace car - the Champion Edition is distinguished by its special livery: The orange grille frame, the matte black hood and trunk with multicolored stripes, the black stripes along its shoulder and rocker panel, and the blacked-out 19-inch wheels all to pay homage to champion Marco Wittmann's racecar, as does special lettering on the rear windows.
Other enhancements include black front splitter and skirts, carbon front flaps and mirror caps, rear spoiler and carbon diffuser, while autographed sill plates and carbon interior trim with the car's serial number adorn the cabin. Only 23 examples will be offered, symbolic of the number adorning the winning tin-top racer and the flank of this special edition as well.

Vorsteiner BMW M4 GTRS4 shows how to do a widebody at SEMA

Part of the joy of the SEMA Show is that all of the best tuners in the world are competing to show off their wares, and the challenge often pushes the companies into some absolutely insane directions. Case in point: Vorsteiner and its ludicrous GTRS4 wide body kit with the BMW M4.
According to Auto Evolution, the kit reportedly adds 4 inches in the front to fit 10.5-inch-wide wheels and a massive 7-inches more in the rear to snug in 13.5-inch-wide wheels, but spinning around the BMW in these images makes the changes look even more extreme. Beyond just the extra room in the fenders, the lower air intakes are ready to suck in huge volumes of cool air, and there's a front splitter to keep things planted. The front and rear extensions are joined by side sills that grow the farther back they go. Finally, at the rear, the M4 gets a reworked diffuser with mesh inserts.
This is just the type of automotive craziness that makes SEMA interesting. Take a lot at it for yourself in the gallery.
