BMW M4 Convertible poised for Goodwood unveil

It shouldn't be a shock that BMW is working on a convertible version of the M4. Not only have we caught it testing twice, but this is an automaker that seems willing to build a vehicle for nearly every buyer's needs. Evo claims that the high-performance droptop is going to debut at this year's Goodwood Festival of Speed in England from June 26-29.
Judging from the spy shots we've seen, the M4 Convertible will consist of a retractable hard top like the 4 Series cabrio. Other than the roof, there aren't expected to be many changes from the coupe. The engine will be the same turbocharged, 3.0-liter inline six-cylinder engine, but the added weight of the roof and its mechanism may take a small bite out of performance.
We spoke to BMW USA about the rumor and were told that it has no comment at this time. After the M4 Convertible, Evo claims that BMW is working on a M4 Gran Coupe. How that would be all that different from an M3, isn't exactly clear.

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.

Next-gen BMW X3 caught in the cold

The BMW X3 might be getting a bit long in the tooth, but fans of the sporty CUV can rest easy knowing that Munich hasn't forgotten about it. The third-generation crossover was caught squeezing in some end-of-season winter testing by our trusty spy photographers. According to our spies, the 2017 X3, code-named G01, will be underpinned by a new modular platform that promises more space in the cabin and better visibility out. Beyond that, the next X3 will get a range of B-series engines; expect four- and six-cylinder options, as well as a plug-in-hybrid option (eventually). Our spies also report that BMW will finally offer some more performance-oriented options, starting with an X3 M40i and eventually expanding into a X3 M. Beyond the oily bits, it looks like the X3's looks are set to evolve, growing slightly compared to its predecessor. BMW's trippy camouflage, though, prevents a closer analysis of the next-gen CUV's styling. Check out our full gallery of spy shots to see what's coming for the X3.
