2015 BMW M4 Coupe ditches some doors, gains some grunt

If you saw our earlier post about the hot new BMW M3 Sedan and were about to call blasphemy for no coupe version, just settle down, silly. Remember: BMW now badges its two-door 3 Series models with the number four, and thus, meet the 2015 M4 Coupe. Looks hot, right?
So yeah, it's pretty much just the M3 with two less doors, but that doesn't make it any less important - or potent. Power comes from a turbocharged, 3.0-liter inline six-cylinder engine, sending 425 horsepower and 406 pound-feet of torque to the rear wheels via either a six-speed manual or seven-speed dual-clutch transmission. You know, the usual.
Not only is the M4 more powerful than the M3 Coupe it replaces, it's a good deal lighter, too. BMW has managed to cut 176 pounds of weight out of the M4, and that means, with the increased output numbers, that the M4 will scoot to 60 miles per hour in 3.9 seconds with the DCT or 4.1 seconds with the do-it-yourself tranny. Either way, that's not what we'd call slow.

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 plans i5 as a useful EV for families

BMW has the often-rumored i5 under development as the next member of its i sub-brand. While the work isn't done yet, look for the future model to be an electric vehicle to appeal to families. To fit the mainstream purpose, BMW's engineers plan to give the new product a long driving range and useful cargo capacity, i product boss Henrik Wenders told Car and Driver. In the brief interview, Wenders shoots down many previous rumors about the i5. For example, he says the model is an EV – not hydrogen fueled or a plug-in hybrid like previous reports claim. However, BMW plans to offer an optional range extender like it does for the i3. "The range-extender plays an important part in the next years when range remains a limiting factor and a source of anxiety," said Wenders. Without saying so directly, the exec also seems to suggest the division wouldn't use the platform from the long-wheelbase 5 Series for the i5, which some reports allege. Instead, Wenders sees the sub-brand as pushing BMW's technological prowess with tech like the current model's extensive use of carbon fiber. According to Wenders, "One of i's roles is as an enabling brand, to help industrialize new materials and processes. We have already opened the door with the i3, and we will take it from there." BMW's EV boss told Autoblog in early 2014 that the company already had the new vehicle under development, but the automaker later denied that claim. With the current lineup, the i3 excels in urban environments, and the i8 is a sports coupe. The next natural step is to offer more room and greater range with the i5. Given the upcoming EV boom from models like the Chevrolet Bolt, Tesla Model 3, and next-gen Nissan Leaf, we're very curious to see BMW's effort to stay competitive in the segment. Related Video:
