BMW 4 Series Gran Coupe blows the doors back on [w/video]

BMW sure seems to take pleasure in confusing the hell out of us. It used to be pretty simple: if you wanted a compact Bimmer, you had to look no further than the 3 Series. Then it was just a matter of which bodystyle you wanted. But the smaller end of BMW's lineup has gotten more complicated lately. Never mind the 1 Series and 2 Series (in their various iterations) that have slotted in below it - now the 3 Series has been split in two: Want a four-door, get the new 3 Series. Want a two-door, the 4 Series is your address. Right?
Almost. Because now there's a 4 Series Gran Coupe that keeps the two-door's roofline (or some approximation of it) but adds an extra set of doors in the back, thereby bridging the gap between the 3 Series sedan and 4 Series coupe. And it's just made its public debut here at the Geneva Motor Show.
The difference between this and the two-door 4 Series is plain to see: it's got two extra doors. But what's the difference between this and the 3 Series sedan? About two or three grand, to start with - depending on which version (428i Gran Coupe or 435i Gran Coupe) you choose. But it's also sleeker, more muscular and altogether that extra bit sexier. Which is a good trait, as you can see from our gallery of live shots above, to have in your European sports sedan, coupe, or whatever you want to call it.

Renderings may show upcoming BMW 4 Series Gran Coupe

We've already shown you spy images of the latest member of the BMW Gran Coupe family, the 4 Series Gran Coupe. Following the trend of the larger 6 Series Gran Coupe, the 4 Series variant grafts a spare set of doors onto its two-door body.
Now, the f30post forum has come up with what it says are patent drawings of the new 4GC (originally from Chinese site Autohome.com), giving a glimpse of what the coupe-sedan-thingy looks like without its camo in the way. What we're seeing is seemingly a mix of the 3 Series GT (noticeable around the rear window) with the larger Gran Coupe styling, while retaining the current 4 Series front end.
We can't say it looks great, but as these are merely renderings, it's far too early for us to come to a final conclusion on the overall look of the 4 Series Gran Coupe. Have a look up top at the patent images. We've also included our spy photos of the new Gran Coupe below. Let us know what you think of the latest niche product from BMW down in Comments.

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.
