2015 BMW M3 Sedan

BMW's all-new M3 Sedan is dynamically nearly identical to its two-door M4 Coupe sibling: a stopwatch reveals that both are sub-four-second cars to 60 miles per hour, a racetrack proves that the mechanical twins are equally as adept on a road course and a full afternoon of driving on public roads demonstrates that each possesses talented everyday adaptability.
Yet after driving both BMW models back-to-back over two full days in Portugal, it's clear there are a few noticeable differences, both objective and subjective, that don't require instrument testing to reveal. All it takes is a few hours behind the wheel of both cars to conclude that one is slightly more agile, and the other a bit more twitchy. One has better outward visibility, while its counterpart is unquestionably more convenient.
It is the little things - subtleties attained through seat-of-the-pants observations - that eventually allow me to choose a favorite.

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.

Apple and BMW have been exploring partnerships on cars

Apple and BMW may eventually have more in common than just some features in your car's infotainment system. Sources for both Reuters and Manager Magazin understand that the two companies have had "exploratory talks," including a trip by Apple executives to Leipzig to see how BMW builds the i3. Apple reportedly likes that BMW rethought the conventional car manufacturing process for its electric vehicle, and might use what it learned to help make its own EV. While BMW claims that there aren't any active talks about jointly developing a car, a Reuters tipster hears that the firms may revive talks (not necessarily to co-produce a vehicle) later on. Not surprisingly, BMW is cautious about any deals. Research lead Klaus Froehlich says the doesn't want to "open [its] ecosystems" to a potential rival. However, it's hard to see the two avoiding each other when they could both use each other's help. Apple knows a lot about user interfaces and integrating mobile technology into cars, but it's a newcomer in creating the cars themselves – that's part of why it's hiring so many auto industry veterans. Meanwhile, BMW knows that it can only do so much to accommodate connected devices without collaborations. You probably won't see an Apple-designed Beemer or an Apple car with loads of BMW-sourced parts, but there's still lots of potential for the corporations to influence each other.
