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.

BMW's Connected Drive feature vulnerable to hackers

BMW is working to fix a cyber-security flaw that has left 2.2 million vehicles worldwide vulnerable to hackers. Cars equipped with the automaker's Connected Drive remote-services system are affected, according to the German Automobile Association (ADAC), which first discovered the problem. Researchers found they could lock and unlock car doors by mimicking mobile communications and sending phony signals to a SIM card installed in affected vehicles. An attack could be launched "within minutes" of accessing the system without the perpetrators leaving a trace, according to their report, in part because once they had gained access to the network, the communications were not secure. In response to the security gap, BMW says it has been upgrading software via over-the-air updates over the past week, so no visits to dealerships are needed to remedy the security hole. In fact, owners of affected cars may not have even noticed the updates taking place. The problem affects BMW, Rolls-Royce and MINI vehicles equipped with Connected Drive since 2010. Flaws were first reported to BMW last year by ADAC, which is the country's equivalent of AAA. ADAC says it withheld a public announcement until the car company could address the problem. While BMW has pushed the software patch to most affected vehicles, the organization said it's possible some at cars in the United States had not yet been updated. BMW did not respond to a request for comment Monday. In a written statement, the automaker said it knows of no real-world breaches. 2015 Off To Dubious Start The hack could raise the eyebrows of industry leaders: Cars are now the equivalent of mobile computers and cyber-security experts have been warning that the auto industry has been slow to close its security holes. BMW's breach marks the second time in 2015 that researchers have found a popular automotive feature with little or no security precautions. Last month, experts said a popular device made by Progressive Insurance that allows motorists to track their driving habits contained no security whatsoever. Like the Connected Drive smart-phone app, many automotive components and infotainment features were conceived and produced at a time when industry executives never considered the possibility someone might want to hack into them. But increased connectivity brings increased risk. Going forward, BMW says its Connected Drive features will now operate by using encrypted communications via the HTTPS protocol.

BMW revisits its 8 Series

So why would BMW choose July 2 to release a retrospective on the 8 Series? Could it have something to do with the recent unveiling of the Pininfarina Gran Lusso Coupe concept, another sleek, B-pillarless V12 two-door, at this year's Villa d'Este? We have no idea, but the timing is likely coincidental.
This three-minute look at the 8 Series talks to Niels Hamann, who was smitten with the long-hooded coupe when it appeared in 1989 and finally bought one in 2004. Hamann also happens to be a project manager at BMW, and that came in handy when he wrote a book detailing every aspect of what was BMW's flagship for ten years but to the chagrin of many only managed one generation.
While we wait for the next clue about the Gran Lusso - 8 Series connection, check out the video below.
